Description:FIELD OF DISCLOSURE
[0001] The present disclosure relates generally relates to the field of water purification technologies. More specifically, it pertains to a solar-powered UV-C water purification bottle system.
BACKGROUND OF THE DISCLOSURE
[0002] Currently, people live in an ever-faster paced world and hence, they always have to have pure and safe water to drink, even when they go hiking, traveling, or just walking around.
[0003] Still, most portable water bottles lack the necessary data about the water's quality, temperature, or the battery level.
[0004] As data that is needed to make a decision is not available, the people are left wondering if their water is safe and sound, especially when they are in outdoor or remote areas.
[0005] Water quality is a serious issue, especially when it comes to the use of untreated water from nature sources such as springs and lakes. Although some of the portable vessels are equipped with filtration systems, they don't have the instantaneous options to tell the water's cleanliness. Therefore, the people are not sure if their water is drinkable.
[0006] Moreover, the level of the temperature of the water is also a thing that the users should know, especially in very hot or cold weather. In cool weather, the water should be kept cold while in warm environments, being able to read the temperature of the bottle can be one of the main features in the process.
[0007] Also, another popular problem is the power supply of the bottle. A lot of the new water bottles that come out along with new features like UV sterilization or smart sensors need to be charged. In the outdoors where the power source is unavailable, it becomes a big issue.
[0008] Having to carry chargers along with the inconvenience of the battery running out is a problem, particularly when it comes to spending time in really remote and power isolated places.
[0009] Eventually, the need for the water bottles that are easily portable and provide information facts about water quality, temperature, and battery status in real-time seems to be higher than ever before.
[0010] The bottle, which solves these issues, not only will be an upgrade of the user experience but it will also guarantee people pure water, properly packed, and delivered where and when they want it.
[0011] Access to safe drinking water is a fundamental human right and a critical necessity for sustaining life. Yet, despite technological advancements, a significant portion of the global population continues to struggle with securing clean, potable water, especially in remote, disaster-affected, or underdeveloped regions.
[0012] The challenges associated with waterborne diseases, contamination by biological pathogens, and the scarcity of infrastructure for large-scale purification systems underscore the urgent need for portable, self-sufficient water purification solutions.
[0013] Against this backdrop, innovations that harness renewable energy sources to enable decentralized water treatment have emerged as promising interventions.
[0014] One such innovation is the integration of ultraviolet-C (UV-C) light technology, known for its germicidal properties, into compact, user-friendly systems designed for individual or small-group use.
[0015] Ultraviolet-C light, with wavelengths between 200–280 nanometers, has been extensively researched and applied in disinfection and sterilization contexts because of its ability to disrupt the DNA and RNA of microorganisms, rendering bacteria, viruses, and protozoa inactive.
[0016] Traditional UV-C purification systems, however, often rely on grid electricity or battery-powered mechanisms that limit their utility in off-grid environments.
[0017] The growing awareness of environmental sustainability and energy independence has driven interest in solar-powered alternatives. A solar-powered UV-C water purification bottle system builds upon this confluence of germicidal technology and renewable energy, offering a means to purify water without reliance on conventional power sources, making it ideal for outdoor enthusiasts, emergency preparedness, military personnel, travelers in developing regions, and communities without access to centralized water treatment facilities.
[0018] The conventional approaches to portable water purification, including chemical tablets, filtration straws, boiling, or hand pumps, each come with inherent drawbacks.
[0019] Chemical treatments may leave undesirable tastes or residues and require precise dosing. Filtration methods, though effective for particulates and some pathogens, may fail against viruses or require filter replacement.
[0020] Boiling demands a heat source and time, while hand pumps necessitate manual effort. By contrast, UV-C disinfection is a non-chemical, non-filtering, non-thermal approach that preserves the water’s natural taste while delivering microbiological safety.
[0021] Yet, portable UV-C devices have faced challenges in ensuring consistent energy supply, waterproofing, and user-friendly operation. The integration of a solar energy harvesting system directly into the water bottle resolves some of these limitations by enabling the device to recharge itself using ambient sunlight, ensuring readiness even in the absence of conventional electricity.
[0022] A control unit manages the charging, discharging, and UV-C activation process, often coupled with an indicator system to inform the user of battery status, purification progress, and maintenance needs.
[0023] Existing patents and products in the field of portable UV-C water purification have generally prioritized either compactness or power efficiency, but many still depend on plugging into a USB charger or external power bank. In remote or prolonged outdoor settings, maintaining access to electricity for recharging such devices is not always feasible.
[0024] Moreover, by integrating the solar panels seamlessly into the bottle’s form factor, the system achieves a balance between aesthetics, ergonomics, and functionality.
[0025] The market demand for water purification solutions continues to expand, fueled by factors such as increased global travel, rising awareness of water quality issues, natural disasters, and humanitarian crises. Portable purification systems are becoming not merely optional accessories but essential survival tools in a variety of contexts.
[0026] Climate change, with its impact on water security and natural disaster frequency, further amplifies the need for innovations that can empower individuals to secure clean water independently of centralized infrastructure.
[0027] Additionally, the proliferation of adventure tourism, camping, trekking, and outdoor recreation has created consumer expectations for reliable, lightweight, and multipurpose hydration solutions.
[0028] From a technological standpoint, advances in UV-C LED miniaturization and efficiency have made it feasible to integrate germicidal light sources into smaller devices without compromising efficacy. Earlier UV-C devices relied on mercury vapor lamps, which posed environmental hazards and bulkiness that hindered portability.
[0029] The transition to solid-state UV-C LEDs reduces energy consumption, extends device lifespan, and enables safer, more environmentally responsible designs.
[0030] Furthermore, improvements in flexible, lightweight photovoltaic materials allow the bottle’s solar panels to conform to curved surfaces without significant loss of energy conversion efficiency.
[0031] These innovations collectively underpin the feasibility and commercial viability of the system disclosed in this document.
[0032] The disclosed system also contemplates user-centered design features to enhance usability. For example, the system may include a one-touch activation button, automatic detection of water presence, or programmable purification cycles tailored to different contamination levels.
[0033] Visual and auditory indicators may guide the user through the purification process, reducing the risk of misuse or incomplete treatment. Additionally, the system’s modular construction may allow for replacement or upgrade of individual components such as the UV-C module, battery, or solar panel, extending product lifespan and adaptability.
[0034] Optional add-ons, such as pre-filtration inserts to remove turbidity or a smartphone application to monitor purification history and battery status, may further enhance user engagement and system versatility.
[0035] In regions affected by humanitarian crises, refugee displacement, or natural disasters, waterborne diseases pose immediate threats to public health. Deploying large-scale water treatment infrastructure under such circumstances is logistically complex and time-consuming.
[0036] Portable purification devices that can be distributed rapidly and used independently by individuals or families fill a critical gap in emergency response. The solar-powered UV-C water purification bottle system disclosed herein offers a solution that empowers users to purify water drawn from variable-quality sources such as streams, wells, rainwater, or containers of uncertain origin.
[0037] By reducing reliance on bottled water deliveries or centralized water points, the system promotes autonomy, reduces plastic waste, and mitigates exposure risks associated with communal water access during disease outbreaks.
[0038] In urban environments, concerns over tap water quality, aging plumbing infrastructure, or accidental contamination incidents have driven interest in point-of-use water treatment devices.
[0039] While countertop filtration systems address some of these concerns, they lack portability and fail to provide microbiological protection against viruses or protozoa.
[0040] Its portability ensures that users are not confined to a single water source, while its solar charging capability ensures that the purification function remains operational without reliance on electricity.
[0041] By leveraging solar energy, it reduces greenhouse gas emissions associated with disposable battery production, transport of bottled water, and reliance on fossil-fuel-derived electricity.
[0042] Its use also contributes to reducing plastic waste by enabling users to refill from safe water sources rather than purchasing single-use plastic bottles.
[0043] Validation of its efficacy under standardized testing protocols ensures user confidence and facilitates adoption across diverse markets. Integration with quality assurance mechanisms, such as tamper-evident seals or maintenance alerts, further reinforces the system’s reliability and safety profile.
[0044] One of the primary disadvantages of the Solar-Powered UV-C Water Purification Bottle System lies in its dependence on solar energy as its primary power source.
[0045] While solar power offers sustainability and off-grid operation, it is inherently variable and unreliable under certain weather conditions. In regions or periods characterized by cloudy skies, heavy rains, or low sunlight intensity, the ability of the solar panel to harvest sufficient energy for UV-C sterilization is compromised.
[0046] This limitation becomes particularly critical during emergencies or in disaster-prone areas where access to both sunlight and electrical alternatives is restricted.
[0047] Users may find themselves unable to recharge the system adequately, leading to incomplete purification cycles and compromised water safety.
[0048] Moreover, the duration of exposure to sunlight required to charge the system sufficiently may not align with users' urgent water consumption needs, especially when purification is required multiple times in a short period.
[0049] Another notable disadvantage is associated with the effectiveness of UV-C light against all types of water contaminants. While UV-C radiation is highly effective at inactivating bacteria, viruses, and protozoa by disrupting their DNA and preventing replication, it does not remove chemical contaminants, heavy metals, or particulate matter present in the water.
[0050] Users relying solely on the Solar-Powered UV-C Water Purification Bottle System may develop a false sense of security regarding water quality, mistakenly believing that all types of contamination have been addressed.
[0051] In scenarios where the water source is polluted with industrial waste, agricultural runoff, or chemical pollutants, the system’s purification mechanism will not neutralize these hazards, potentially posing health risks if consume without additional filtration steps.
[0052] Therefore, the system may require pre-filtration or additional purification technologies to achieve comprehensive water safety, increasing complexity and cost.
[0053] The durability and longevity of UV-C lamps or LEDs used in the system represent another disadvantage that cannot be overlooked. UV-C emitting components have a finite lifespan, typically measured in thousands of operating hours.
[0054] Over time, the intensity of UV-C output diminishes, reducing the system’s disinfection efficacy even if the device continues to operate visually. Users may not have access to tools or indicators to measure the declining UV-C intensity, leading to unnoticed degradation in performance.
[0055] In addition, replacing UV-C lamps or LEDs may not be readily feasible for users in remote or underdeveloped areas, especially if spare parts are proprietary or require specialized installation.
[0056] If the UV-C emitter fails or reaches the end of its service life, the entire system becomes non-functional for its intended purpose unless replaced or repaired, leading to potential water safety risks and additional maintenance burdens.
[0057] The structural design and material composition of the Solar-Powered UV-C Water Purification Bottle System may also introduce disadvantages in terms of durability, weight, and usability.
[0058] Integrating a solar panel, UV-C light source, battery, and control circuitry within a portable bottle adds complexity and fragility compared to conventional water bottles.
[0059] Exposure to rough handling, accidental drops, or extreme environmental conditions such as high heat or freezing temperatures may damage electronic components, rendering the purification system inoperable.
[0060] Outdoor users engaged in activities like hiking, camping, or trekking may find the system less rugged than traditional water containers, raising concerns about its reliability in challenging terrains.
[0061] Additionally, the inclusion of electronic components increases the overall weight of the bottle, which can be a drawback for users prioritizing lightweight gear for long-distance travel or expeditions.
[0062] The cost of acquiring and maintaining a Solar-Powered UV-C Water Purification Bottle System is another disadvantage that limits its accessibility to a broader population.
[0063] Compared to standard water bottles or simple filtration systems, the integration of solar panels, rechargeable batteries, UV-C LEDs, and smart control features drives up the initial purchase price.
[0064] For users in low-income regions or developing countries where access to clean water is already a challenge, the affordability of such a system may be prohibitive.
[0065] Furthermore, the need for eventual battery replacements, UV-C emitter replacements, and potential repairs introduces recurring expenses over the lifespan of the device.
[0066] When evaluating total cost of ownership, the system may not represent a cost-effective solution for all users, particularly when alternative water purification methods exist at a fraction of the cost.
[0067] User dependency on proper usage protocols also emerges as a disadvantage in the practical operation of the Solar-Powered UV-C Water Purification Bottle System.
[0068] Achieving effective disinfection requires correct user input, including ensuring that water is clear (as turbidity reduces UV-C penetration), filling the bottle to the designated level, securely closing the lid to prevent UV-C leakage, and initiating the purification cycle for the recommended duration. Users unfamiliar with these requirements may inadvertently skip critical steps or misunderstand indicators, leading to incomplete purification.
[0069] Moreover, if instructions are complex or poorly communicated, user errors may compromise the safety of treated water without immediate detection. In contrast, simpler mechanical filtration systems have fewer steps susceptible to user error.
[0070] Battery degradation and charge retention present further challenges associated with solar-powered systems incorporating rechargeable batteries. Over multiple charge-discharge cycles, battery capacity diminishes, resulting in shorter operating times and longer charging requirements.
[0071] If the battery is unable to hold sufficient charge due to aging or poor maintenance, the user may struggle to achieve a full purification cycle even under optimal sunlight. In extreme temperatures, both heat and cold negatively affect battery performance, reducing the system’s functionality under harsh environmental conditions.
[0072] Without accessible battery replacement options, the entire system’s operational life becomes tethered to battery longevity, diminishing sustainability in the long term.
[0073] The system’s suitability for purifying large volumes of water is another limiting factor. Given its portable bottle design, the purification capacity is typically confined to one bottle at a time, making it inefficient for situations requiring water for multiple people or extended stays in off-grid areas.
[0074] Users needing to purify several liters of water for cooking, cleaning, or group consumption must repeat the purification process multiple times, leading to delays, user fatigue, and reduced practicality.
[0075] In contrast, larger purification systems with higher throughput are better suited for communal or prolonged outdoor use, leaving the Solar-Powered UV-C Water Purification Bottle System primarily useful for individual, small-volume applications.
[0076] Another significant disadvantage stems from regulatory and certification challenges related to UV-C disinfection systems. In some regions, water treatment devices are subject to testing and certification to verify their disinfection claims.
[0077] If the Solar-Powered UV-C Water Purification Bottle System lacks necessary certifications or regulatory approvals, users may hesitate to trust its efficacy or face restrictions on import, sale, or use in certain jurisdictions.
[0078] Moreover, without standardized performance validation, consumers may struggle to compare different products or verify marketing claims, leading to skepticism or misuse.
[0079] Environmental factors, such as dust, dirt, or water ingress, may further impair the functionality of the solar panel and electronic components integrated into the system.
[0080] In outdoor environments, exposure to mud, sand, rain, or humidity may accumulate on the solar panel surface, reducing energy harvesting efficiency. If users are unaware of the need to regularly clean the solar panel, prolonged exposure to contaminants may lead to permanent damage or degradation.
[0081] Similarly, poor waterproofing of electronic housings could allow moisture to penetrate internal circuitry, causing short circuits or corrosion. These environmental vulnerabilities require additional care, maintenance, and design considerations to mitigate risks.
[0082] Finally, from a sustainability perspective, the Solar-Powered UV-C Water Purification Bottle System introduces e-waste concerns at the end of its usable life.
[0083] Unlike conventional bottles that can be recycled through standard plastic recycling streams, the integration of electronic components, batteries, and specialized materials complicates disposal.
[0084] Users may lack access to appropriate e-waste recycling facilities, especially in rural or low-resource areas, leading to improper disposal practices.
[0085] The environmental impact of discarded electronics, including potential leaching of heavy metals from batteries, offsets some of the ecological benefits gained from solar-powered operation.
[0086] Thus, in light of the above-stated discussion, there exists a need for a solar-powered UV-C water purification bottle system.

[0124] A solar-powered UV-C water purification bottle system 100 comprises a bottle body 102 configured to hold a volume of water. The bottle body 102 comprises insulated walls to maintain the temperature of the water for a prolonged period.
[0125] The system also includes a cap 104 removably attached to the bottle body. The cap 104 is configured to be disassembled for cleaning and replacement of the UV-C light source or solar panel without tools.
[0126] The system also includes an ultraviolet-C (UV-C) light source 106 configured to emit UV-C radiation into the water contained in the bottle body to inactivate or destroy harmful microorganisms.

[0127] The system also includes a solar panel 108 configured to generate electrical energy from sunlight to charge an internal battery. The solar panel 108 is positioned on an exterior surface of the cap to maximize sunlight exposure when the bottle is placed upright.
[0128] The system also includes a control circuit 110 configured to regulate power distribution and control the operation of the UV-C light source. The control circuit 110 is further configured to provide an alert to the user via the display when the battery charge level falls below a predefined threshold. The control circuit 110 is configured to prioritize power supply to the UV-C light source during purification cycles and redirect excess power to battery storage when purification is not active.
[0129] The system also includes a touch-enabled display 112 configured to provide real-time information to a user including at least water temperature, battery charge level, and UV-C purification status. The touch-enabled display 112 further displays a countdown timer indicating remaining purification time during the purification cycle. The touch-enabled display 112 is configured to notify the user when the UV-C light source has reached the end of its operational life and requires replacement.
[0130] The system also includes a user interface 114 associated with the touch-enabled display and operable to activate the UV-C light source for initiating a purification cycle.
[0131] A method for a solar-powered UV-C water purification bottle comprises filling a bottle with water from an external source. The method also includes closing the bottle to enable activation of an integrated purification and monitoring system. The method also includes initiating a purification cycle by a user input via a touch display on the bottle. The method also includes emitting UV-C light from a UV-C LED integrated into a cap of the bottle to irradiate the water for a predefined duration sufficient to eliminate bacteria, viruses, and harmful microorganisms. The method also includes monitoring in real-time, via the touch display, at least one of water temperature, battery charge level, and purification status. The method also includes charging a battery of the bottle automatically by harvesting solar energy through a solar panel embedded in the cap when exposed to sunlight. The method also includes notifying the user via the touch display when at least one of the purification processes is complete, the battery level is low, or the UV-C light requires replacement. The method also includes allowing disassembly of at least the cap for maintenance, cleaning, or replacement of components including the UV-C LED or the solar panel.
[0132] FIG. 1 illustrates a flowchart outlining sequential step involved in a solar-powered UV-C water purification bottle system.
[0133] At 102, the process begins as the user prepares the bottle for use by filling the bottle body with water sourced from any external source, such as a tap, stream, or lake. The bottle body is designed with a sufficient capacity to hold a meaningful volume of water while maintaining portability for outdoor, travel, or everyday applications.
[0134] At 104, once filled, the user securely fastens the cap onto the bottle body, effectively sealing the contents and creating an enclosed environment necessary for the controlled purification process. This sealing action not only prevents contamination from external factors but also mechanically and electronically engages the system’s internal components, setting the stage for the purification cycle to commence.
[0135] At 106, inside the cap, a strategically integrated ultraviolet-C (UV-C) light source is poised to perform its pivotal role in water sterilization. This UV-C light source is configured to emit germicidal UV-C radiation at wavelengths typically ranging from 200 to 280 nanometers, targeting the DNA and RNA of harmful microorganisms such as bacteria, viruses, and protozoa present in the water. By disrupting their genetic material, the UV-C light renders these pathogens inactive, preventing their ability to reproduce and cause infection. However, the emission of UV-C light does not occur automatically; instead, it is initiated through user input via a user interface that is seamlessly integrated with a touch-enabled display positioned on the exterior of the bottle or cap. This user interface empowers the user with direct control, allowing the initiation of the purification cycle at their discretion by simply tapping or selecting an activation option on the display.
[0136] At 108, the display further indicates the battery charge level, drawing input from the energy management subsystem linked to a solar panel mounted on the cap. This solar panel harnesses sunlight, converting solar energy into electrical energy via photovoltaic cells and routing this energy to charge an internal battery housed within the cap. The solar panel enables sustainable, off-grid operation, especially valuable in remote or outdoor settings where conventional power sources are unavailable. While the purification cycle is underway or when the bottle is exposed to sunlight, the system continues to recharge its battery autonomously, ensuring that the UV-C light source remains ready for future use without reliance on external charging equipment.
[0137] At 110, upon receiving the user’s activation input, the system’s control circuit becomes operational. This control circuit serves as the central processing and regulation hub for the system, coordinating the distribution of electrical power and managing the timing, intensity, and duration of UV-C light emission. The control circuit ensures that sufficient energy is delivered from the internal battery to the UV-C light source for the prescribed duration necessary to achieve effective microbial inactivation. The duration and intensity are pre-programmed based on scientific data correlating UV-C dosage with pathogen inactivation efficacy, guaranteeing reliable purification even in field conditions.
[0138] As the UV-C light source begins to emit radiation into the water, the touch-enabled display transitions into a dynamic information interface, visually conveying a countdown timer or progress bar that informs the user of the ongoing purification status. This real-time feedback enhances user confidence and provides clear expectations regarding when the water will be safe to consume.
[0139] Simultaneously, the display also monitors and communicates additional vital metrics. Embedded sensors within the system feed continuous data to the display, allowing it to present real-time water temperature, giving users an understanding of whether the water’s thermal conditions align with their intended use, such as drinking or hydration during hot weather.
[0140] At this juncture, the control circuit signals the UV-C light source to cease radiation emission, and the touch-enabled display communicates a completion notification to the user, often accompanied by visual cues such as a checkmark icon or an audible signal. This notification informs the user that the water has been effectively purified and is now safe for drinking. Notably, the system may also log the number of purification cycles completed or track the cumulative operation hours of the UV-C light source, enabling predictive maintenance or replacement alerts for the UV-C module to ensure ongoing efficacy. Such notifications may appear on the display (112) under the form of a maintenance icon or message, alerting users when the UV-C light has approached the end of its operational lifespan and should be replaced to maintain purification performance.
[0141] In the broader operational cycle, the solar-powered UV-C water purification bottle system offers continuous monitoring and passive charging functionality even outside active purification sessions. The solar panel remains exposed to ambient sunlight whenever possible, steadily trickle-charging the internal battery under the management of the control circuit
[0142] At 112, the display provides ongoing updates of the battery’s charge status, including percentage indicators or color-coded battery icons, thereby empowering users to plan accordingly, especially when venturing into environments with unpredictable sunlight exposure. In instances where the battery level falls below a predefined threshold, the system is designed to generate a low-battery alert, visually prompting the user to expose the bottle to sunlight for recharging or take alternative measures to restore power before the next purification cycle.
[0143] Throughout its operation, the solar-powered UV-C water purification bottle system integrates layers of safety protocols and user safeguards managed by the control circuit. For example, the control circuit may be programmed to inhibit UV-C light activation unless the cap is securely fastened onto the bottle body, preventing accidental UV-C exposure to the user’s eyes or skin. Additionally, the system may implement thermal monitoring to prevent overheating of electronic components under prolonged solar charging or intense environmental heat, automatically modulating charging rates or deactivating non-critical functions to preserve system integrity.
[0144] At 114, beyond purification, the user interface also functions as a command center for auxiliary settings and customization. Depending on the implementation, users may access settings menus via the touch-enabled display to adjust display brightness, review purification logs, or select between preset purification durations tailored for varying water qualities. For instance, a user collecting water from a known municipal source may opt for a shorter purification cycle, whereas water sourced from natural bodies might warrant a longer cycle. This configurability further amplifies the versatility and user empowerment delivered by the system.
[0145] In terms of maintenance, the solar-powered UV-C water purification bottle system engineered for user-friendly disassembly. The cap can be unscrewed or detached, providing access to internal components such as the UV-C light source, the solar panel, and the battery compartment. Users are thus enabled to clean, inspect, or replace these components as part of routine upkeep, extending the product’s usable lifespan and sustaining purification effectiveness. The modular design ensures that even users without technical expertise can manage basic maintenance tasks, supported by guidance prompts or instructional icons displayed on the touch-enabled display.
[0146] The entire flow of operations embodies a harmonious integration of mechanical design, electronic control, user interaction, and sustainable energy utilization, culminating in a holistic solution that addresses modern hydration needs with technological sophistication.
[0147] Furthermore, the system achieves a synergy between automation and user control. While key functions such as purification timing, solar charging, and status monitoring are automated for convenience and reliability, the user retains critical decision-making authority over when to initiate purification cycles, interpret displayed information, and respond to alerts. This balance of autonomy and oversight fosters trust and confidence in the system, reassuring users that they can depend on the device under diverse conditions, whether navigating urban commutes, trekking wilderness trails, or preparing emergency water supplies during crises.
[0148] FIG. 2 illustrates a block diagram showing working of a solar-powered UV-C water purification bottle system.
[0149] At 202, at the top of the diagram is the solar panel component, colored in bright yellow, signifying its role as the energy harvesting unit. The solar panel is responsible for converting solar energy into electrical power through photovoltaic cells. It possesses attributes such as power output, efficiency, and size, which define the electrical output capacity, energy conversion efficiency, and physical dimensions of the solar panel, respectively. The key function generate power encapsulates its behavior of generating electrical energy when exposed to sunlight. This power generation process is essential because it ensures that the system remains functional even in remote areas without traditional power sources.
[0150] At 204, the solar panel directly powers the next module, the battery, depicted in blue. The battery serves as the energy storage unit for the system, ensuring that power is stored for use even when sunlight is unavailable. The attributes capacity, charge level, and voltage characterize the total amount of energy the battery can hold, the current charge status, and the voltage output, respectively. The Battery’s functions include store power to capture the energy generated by the solar panel and provide power to deliver power to downstream components as needed. This ensures uninterrupted operation of the system regardless of fluctuations in solar energy availability.
[0151] At 206, the battery provides power to the voltage regulator, colored green. The voltage regulator's role is critical in stabilizing the voltage received from the battery, ensuring that sensitive electronic components receive a consistent voltage level to prevent malfunction or damage. Its attributes include input voltage and output voltage, representing the voltage levels at the input and output terminals, respectively. The function regulate voltage represents the regulator’s core functionality—adjusting and stabilizing voltage to meet the operational requirements of the subsequent modules.
[0152] At 208, once the voltage is regulated, it supplies power to the microcontroller, represented in pink. The microcontroller acts as the central processing unit (CPU) of the system, orchestrating the control, monitoring, and decision-making processes. It holds attributes such as processor speed and memory size, indicating its computational power and data storage capacity. The microcontroller executes multiple core functions: control UV light to manage the activation and deactivation of the UV-C light; display status to send updated data to the display module; and read sensor data to collect information from connected sensors.
[0153] The microcontroller simultaneously interacts with three different components the UVC light, the temperature sensor, and the display. Each interaction represents an important facet of the water purification system.
[0154] At 210, the UVC light component, colored in orange, is controlled by the Microcontroller through the control UV light function. This module embodies the UV-C light source that emits germicidal UV-C radiation into the water to neutralize bacteria, viruses, and other pathogens. It has attributes such as intensity, indicating the strength of the emitted UV light, and lifetime, referring to the operational lifespan of the UV bulb. Its functional methods include activate light to turn on the UV-C emission during purification cycles, and deactivate light to switch it off after the process completes or when idle to conserve energy and extend lifespan. This targeted UV-C exposure is what purifies the water inside the bottle.
[0155] At 212, parallel to UV light control, the microcontroller reads data from the temperature sensor, colored in light blue. The temperature sensor continuously monitors the temperature of the water within the bottle. It holds attributes such as temperature range, denoting the range of temperatures it can accurately detect, and accuracy, specifying the precision level of its readings. The function read temperature captures real-time temperature data and transmits it back to the Microcontroller. This temperature monitoring is crucial for user safety and system validation—extremely high or low temperatures might influence purification effectiveness or user health.
[0156] At 214, in addition to controlling and reading data from internal components, the microcontroller also controls the display, illustrated in purple. The display provides a user interface for real-time feedback and interaction. It possesses attributes like screen size and resolution, which dictate its physical display dimensions and the clarity of the visuals presented. The display hosts multiple functions: show temperature to display current water temperature, show battery status to indicate remaining battery life, and show UV status to inform the user about the current status of the purification cycle (e.g., in-progress, complete, or idle).
[0157] The interactions among these components follow a logical, sequential, and feedback-driven process to achieve effective water purification. Initially, the solar panel harvests energy and charges the battery, which stores and supplies the necessary electrical power. The voltage regulator ensures the voltage delivered to the microcontroller and other electronics remains within safe operating limits. Upon user input or programmed schedule, the microcontroller activates the UV-C light to initiate a purification cycle. Concurrently, the microcontroller reads data from the temperature sensor to monitor water conditions and sends real-time updates to the display for user visibility. Once the purification cycle completes, the UV-C light is deactivated, and the user is notified through the display interface.
[0158] Throughout this process, the system incorporates real-time monitoring and user notification mechanisms, ensuring transparency, safety, and convenience. The microcontroller’s role as the central coordinator integrates all modules seamlessly, creating an autonomous system that leverages renewable energy, intelligent control, and user-centric design.
[0159] The figure encapsulates a highly integrated system where energy generation, power management, processing, sensing, control, and human interaction converge into a compact, portable water purification device. This design not only empowers users in remote or off-grid locations to access safe drinking water but also demonstrates technological innovation through sustainability, automation, and real-time information sharing.
[0160] Additionally, the system’s modular design facilitates maintenance and upgrades. For instance, if the UV-C light reaches the end of its lifecycle, it can be replaced independently without affecting other components. Similarly, advancements in solar cell efficiency or display technology could be incorporated in newer iterations by upgrading the respective modules while retaining the overall system architecture.
[0161] The use of a touch-enabled display further enhances usability by offering an intuitive interface for interacting with the system. Users can initiate purification cycles, check status indicators, and receive alerts (such as low battery warnings or UV-C bulb replacement notifications) through simple touch gestures. This reduces the need for external devices or complex operational procedures, making it accessible to users of all ages and technical backgrounds.
