Description:FIELD OF THE INVENTION

[0001] The present invention relates to a personalized beverage preparation device that is capable of preparing beverages based on user’s health information and personal taste to cater user specific needs and maintain the same quality and mix of ingredients, thus ensuring consistent and personalized results.

BACKGROUND OF THE INVENTION

[0002] Beverages are a vital part of daily consumption and serve various purposes ranging from hydration and refreshment to health and nutrition. In recent years, there has been a growing trend toward personalized health and wellness solutions. As a result, users now seek customized beverages that match their specific health requirements, taste preferences, and lifestyle choices. Beverage preparation devices have therefore become common in households, offices, and fitness centers, with users expecting greater control over what they consume, along with convenience and hygiene.

[0003] Traditionally, beverage preparation involved manual processes using basic tools such as kettles, pots, spoons, and cups. Users would heat or cool water, mix ingredients like tea leaves, coffee powder, sugar, milk, or other additives manually, and pour the drink into containers. In some cases, mechanical machines such as blenders or dispensers were used, but these required constant human intervention and lacked automation. Additionally, health-specific personalization, such as adjusting the composition based on a person’s medical or fitness data, was not possible using these conventional methods.

[0004] These traditional practices often led to inconsistent taste, incorrect additive quantities, spillage, and lack of hygiene. Manual errors were common, especially when the user was in a hurry or had limited knowledge of ingredient proportions. The absence of automated control made it difficult to prepare beverages with specific temperatures or nutritional components. Furthermore, maintaining hygiene through cleaning and sterilization was a time-consuming process, increasing the chances of contamination and bacterial growth in reusable containers.

[0005] US8490829B2 discloses about systems and methods for dispensing compositions, such as beverages, are provided. Beverage dispensers may be configured to receive one or more physiological parameters regarding a user, and in response, formulate at least one beverage recipe for dispensing. A beverage dispenser may wirelessly receive data from a biosensor. Environmental or biological data from the biosensor may be used to alter the recipe to another existing beverage or a custom beverage. Non-physiological data may also be considered. Exertion data may be calculated. The calculation of exertion data may receive inputs regarding at least one physiological parameter and/or non-physiological parameters to derive a second physiological parameter not being measured.

[0006] US7899713B2 discloses about a system and method for creating a personalized consumer product are provided. The system and method of the present disclosure enables a user, e.g., a consumer, to customize products containing solids and/or fluids by allowing a server communicating over the global computer network, e.g., the Internet, to provide product preferences of a user to a product or a mixing device, e.g., a product or beverage dispenser.

[0007] Conventionally, many devices are available for preparing beverage as per user’s choice. However, the cited arts exhibit certain limitations, where the devices fail to automate the beverage preparation process, lack real-time health data integration, and do not provide sufficient customization or hygiene measures tailored to individual user needs and changing physiological conditions.

[0008] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that requires to enable personalized beverage preparation by integrating real-time health monitoring, automated additive dispensing, and hygienic operation. In addition, the device also needs to ensure accuracy, consistency, and user-specific customization, while minimizing manual intervention and maintaining cleanliness between consecutive uses.

[0023] The present invention relates to a personalized beverage preparation device that is capable of preparing beverages for a user by using personal health data and preference inputs, ensuring the drink supports their specific medical needs and taste choices, thereby reducing manual efforts and enhancing overall user-experience.

[0024] Referring to Figure 1, an isometric view of a personalized beverage preparation device is illustrated, comprises of a hollow body 101 with upper and lower chambers 102 103, a spill-proof lid 104 integrated with the upper portion of the body 101, a handle 105 attached to the body 101 through a gimbal arrangement 106, a solenoid valve 107 positioned at a bottom periphery of the upper chamber 102, a plurality of additive containers 108 arranged on an outer periphery of the upper chamber 102, and connected via conduits 109 to the solenoid valve 107, a mixing impeller 110 installed within the lower chamber 103, an iris valve-based dispensing unit 111 operatively connected to the lower chamber 103, fingerprint authentication module 112 is integrated with the body 101 and a LED (Light Emitting Diode) display 113 is mounted on an outer periphery of the body 101.

[0025] The present invention includes a hollow body 101 with upper and lower chambers 102 103 for customized beverage preparation. The chambers mentioned herein but not limited to food-grade stainless steel, BPA-free food-grade plastic, are Borosilicate glass for ensuring safety, maintain beverage quality.

[0026] The preferred material for the chambers is made from food-grade stainless steel, which is safe for storing and mixing beverages. This material is non-toxic, rust-resistant, and does not react with the beverage or additives, ensuring hygiene and taste preservation. The material maintains the purity and taste of the beverage, resists bacterial growth, and withstands temperature variations during heating or cooling.

[0027] The upper chamber 102 stored with beverage and featuring a spill-proof lid 104 with an airtight silicone gasket. The lid 104 is fitted with the airtight silicone gasket ensures a secure seal, maintaining freshness and preventing contamination. This airtight design helps preserve the beverage’s temperature and quality while enhancing safety and hygiene.

[0028] The airtight silicone gasket mentioned herein is a ring-shaped sealing component, typically made of food-grade silicone, placed inside the lid 104 to create airtight and leak-proof seal between the lid 104 and the chamber. The gasket prevents liquid from spilling or leaking, especially during movement. In the context of the invention, the gasket helps maintain beverage hygiene, freshness, and safety throughout the preparation and dispensing process.

[0029] A handle 105 attached to the body 101 through an arrangement 106, allowing to pivot freely and maintain body’s orientation during motion. The handle 105 is designed and securely fixed to the body 101, allowing a comfortable and firm grip for the user. The handle 105 is made from durable, food-safe material with heat-resistant properties to ensure safe handling of hot or cold beverages. The handle's shape and texture enhance usability, enabling the user to carry or use the device with ease and stability.

[0030] The gimbal arrangement 106, allowing to pivot freely and maintain body’s orientation during motion. The gimbal arrangement 106 mentioned herein includes an outer ring, a middle ring, and an inner ring, each nested within the other to allow multi-axis rotation. These rings are connected through pivot joints or bearings that enable smooth and controlled movement across different axes. The arrangement further includes support brackets or arms hold the entire setup together and ensure structural stability. This arrangement allows the body 101 of the device to maintain its upright orientation regardless of the user's hand motion.

[0031] In an embodiment of the present invention, a user is required to access and presses a push button arranged on the body 101 to activate the device for associated processes of the device. The push button when pressed by the user, closes an electrical circuit and allows currents to flow for powering an associated microcontroller of the device for operating of all the linked components for performing their respective functions upon actuation. The microcontroller, mentioned herein, is preferably an Arduino microcontroller. The Arduino microcontroller used herein controls the overall functionality of the linked components.

[0032] A user interface is installed in a computing unit linked with a microcontroller inbuilt in the device to wirelessly connect device with computing unit by means of a communication module. The user interface enables the user to provide physical and medical information as input into a user-profile of the user, and later this user-profile is stored in a database. The database stores various types of user-specific data, including age, weight, height, medical conditions (such as diabetes or hypertension), dietary preferences, daily nutritional requirements, and preferred beverage temperature or additives. This information helps the microcontroller customize beverage composition, additive type and quantity, and temperature settings to suit the user's health needs and personal preferences for optimal results.

[0033] The communication module mentioned herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module used in the device is preferably the Wi-Fi module. The Wi-Fi module enables wireless communication by transmitting and receiving data over radio frequencies using IEEE 802.11 protocols. It connects to a network via an access point, converting digital data into radio signals. The module processes TCP/IP protocols for data
exchange, interfaces with microcontrollers through UART/SPI, and ensures
encrypted communication using WPA/WPA2 security standards for secure and
efficient wireless connectivity.

[0034] For example, a user with diabetes inputs their condition, age, and dietary preferences into the interface. The microcontroller stores this data in the database and, during preparation, the microcontroller selects low-sugar additives, adjusts the beverage temperature to 50°C, and ensures precise nutrient composition delivering a personalized drink that aligns with the user’s health condition and daily nutritional needs.

[0035] A fingerprint authentication module 112 is embedded into the body 101 to recognize the user and access their pre-configured profile, which contains personalized settings such as preferred temperature, beverage flow rate, and specific additive combinations. These settings are stored in the device’s internal memory and are automatically retrieved and adjusted by the microcontroller.

[0036] The fingerprint authentication module 112 stores biometric data to uniquely identify users. Upon successful scan, the microcontroller retrieves the associated user profile from internal memory, which includes personalized settings such as preferred beverage temperature, flow rate, and additive ratios. The temperature setting guides, flow rate, and additive ratios. These parameters are pre-defined by the user via the interface and are stored in structured memory blocks, ensuring the beverage is prepared to the user’s exact preferences without requiring manual input each time.

[0037] For example, when a user places their finger on the fingerprint scanner, the module 112 recognizes them and automatically prepares a warm herbal tea at 55°C with a slow flow rate and a 2:1:1 ratio of vitamins, minerals, and antioxidants, based on their pre-saved preferences, eliminating the need for re-entering settings each time.

[0038] A health monitoring unit including a galvanic skin response sensor and a photo plethysmography sensor is integrated with the handle 105 for collecting physiological parameters of the user, and accordingly customizing the beverage compositions.

[0039] The Galvanic Skin Response (GSR) sensor measures the electrical conductance of the skin, which varies with perspiration levels triggered by emotional or physiological changes. Electrodes embedded in the handle 105 make contact with the user’s skin and detect minute fluctuations in conductivity. These variations are indicative of stress, excitement, or relaxation levels. The sensor generates analog signals proportional to skin resistance, which are converted into digital data by an onboard analog-to-digital converter. This data is transmitted to the microcontroller, which evaluates the user’s emotional state and accordingly adjusts the beverage’s additive composition.

[0040] For example, if the GSR sensor detects increased skin conductance indicating high stress, the microcontroller interprets this as a need for relaxation. The sensor then adjusts the beverage composition by selecting calming additives such as chamomile or magnesium-based supplements, ensuring the prepared drink helps soothe the user’s stress and supports emotional well-being in real time.

[0041] The Photo plethysmography (PPG) sensor operates using a light source typically an LED—and a photodetector embedded within the handle 105. The sensor projects light onto the user's skin, usually at the fingertip or palm, and measures the amount of light reflected or absorbed, which varies with blood flow. These changes correspond to the cardiac cycle, allowing the sensor to calculate heart rate and blood oxygen levels. The data is processed by the microcontroller, which analyzes cardiovascular health in real time. Based on these readings, the microcontroller customizes beverage parameters, such as electrolyte balance, fluid volume, or stimulant concentration, to support user-specific physiological needs.

[0042] For example, if the PPG sensor detects a rapid heart rate and low blood oxygen level after a workout, the microcontroller analyzes this data and prepares a rehydrating beverage enriched with electrolytes and a lower stimulant concentration, helping the user recover efficiently while maintaining cardiovascular balance and preventing dehydration or overexertion-related issues.

[0043] Multiple additive containers 108 are positioned around the outer edge of the upper chamber 102, each containing health-oriented additives and linked to a solenoid valve 107 through conduits 109. The additives mentioned herein stores health-based ingredients (like vitamins, minerals, or herbal extracts). This enables controlled additive delivery into the valve 107. The solenoid valve 107 mentioned herein is a, cylindrical electromechanical component mounted at the bottom periphery of the upper chamber 102. The valve 107 is integrated directly into the chamber wall, allowing a secure and sealed connection for enabling beverage flow to the lower chamber 103.

[0044] The microcontroller actuates the solenoid valve 107 by sending an electrical signal based on the preset dispensing parameters. The solenoid valve 107 mentioned herein consists of a coil, plunger, and a spring. When energized, the coil generates a magnetic field that lifts the plunger against the spring force, opening the flow path for the beverage. Upon deactivation, the spring returns the plunger to its original position, sealing the valve 107 to prevent leakage.

[0045] A level sensor (not shown in figure) is integrated with each of the container and operable by for dispensing additives based on user-specific health data. The microcontroller actuates the level sensor to detect the quantity of additives in each container and regulate their dispensing based on user-specific health data. Each level sensor is positioned within the additive container and functions by continuously measuring the fluid level using capacitance principles. When the user inputs a request, the microcontroller compares the required additive amount with the current level data. If adequate volume is available, the microcontroller signals the corresponding valve 107 to dispense the correct quantity.

[0046] A mixing impeller 110 positioned inside the lower chamber 103, designed to thoroughly blend the beverage with the added health-based additives. The microcontroller actuates the mixing impeller 110 by sending electrical signals to a motor integrated within the lower chamber 103, which rotates the impeller 110 at a controlled speed. The impeller 110 features multiple angled blades to create a turbulent flow, ensuring uniform blending of the beverage and additives. The speed and duration of mixing are regulated based on predefined user settings stored in the device database.

[0047] An RPM (revolutions per minute) sensor (not shown in figure) is functionally linked to the impeller 110 and designed to regulate the rotational speed according to the beverage volume and the amount of additives. The microcontroller actuates the RPM (revolutions per minute) sensor by sending control signals based on input data from the level sensors and additive dispensing logs. The sensor continuously monitors the impeller’s rotational speed and adjusts dynamically to ensure optimal mixing performance. Based on the calculated beverage volume and additive concentration, the sensor ensures that the impeller 110 operates at a suitable speed for uniform blending.

[0048] A Peltier-based thermal regulation unit (not shown in figure), coupled with a temperature sensor, is incorporated within both the upper and lower chambers 102 103 to manage the heating or cooling of the beverage. They both adjust the temperature according to the user’s predefined preferences, ensuring the beverage is delivered at the desired thermal condition for optimal comfort and health benefits.

[0049] The microcontroller actuates the Peltier-based thermal regulation unit by supplying current based on the desired temperature input. The Peltier unit operates on the thermoelectric effect, creating a temperature differential across two sides one becomes hot while the other becomes cold. The cold side cools the beverage, and the hot side dissipates heat via heat sinks. The Peltier unit reverse polarity to switch between heating and cooling modes, ensuring precise thermal control based on user settings.

[0050] The temperature sensor (not shown in figure) used herein is preferably a digital thermistor due to accuracy, reliability, and fast response time. The digital thermistor, such as the NTC (Negative Temperature Coefficient) type, changes its resistance with variations in temperature and provides precise readings suitable for beverage applications. The sensor relays temperature data to the microcontroller continuously. The microcontroller processes this input to control the Peltier unit, ensuring the beverage remains within the user-defined temperature preferences.

[0051] The lower chamber 103 is connected to an iris valve-based dispensing unit 111, which is used to discharge the blended beverage into an external receptacle in a controlled manner, preventing spills and allowing for easy collection.

[0052] The iris valve-based dispensing unit 111 mentioned herein, is an adjusting circular aperture comprised of an actuation ring and a plurality of blades according to the size of the iris valve-based dispensing unit 111. The blades are engraved with the protrusions through which the actuation ring is affixed to each blade. The actuation ring is connected to a motor, which helps in the movement of the actuation ring leading to the movement of blades inward or outward to change the size of the opening. When the blades close, the aperture becomes smaller, closing the iris valve-based dispensing unit 111. When the blades open, the aperture widens, opening the lid 104. This adjustment allows iris valve-based dispensing unit 111 iris lid 104 to control the blended beverage from the lower chamber 103 to the external receptacle.

[0053] A load sensor (not shown in figure) integrated with the lower chamber 103 to detect beverage depletion. The microcontroller continuously monitors signals from the load sensor integrated with the lower chamber 103 to determine the weight of the contained beverage. The load sensor, based on strain gauge technology, detects changes in mass as the beverage is dispensed. This data is converted from analog to digital using an ADC (Analog to Digital converter) module and sent to the microcontroller for analysis of beverage depletion. When the detected weight falls below a predefined threshold, indicating beverage depletion.

[0054] To ensure hygiene, a UV (Ultraviolet) sterilization unit is integrated within the lower chamber 103 for disinfecting the lower chamber 103 before subsequent use. The microcontroller actuates the UV (Ultraviolet) sterilization unit upon receiving input from the load sensor indicating beverage depletion. The UV sterilization unit, integrated within the lower chamber 103, comprises of a UV-C light-emitting diode (LED) calibrated to emit germicidal wavelengths between 200–280 nm.

[0055] When activated, the LED irradiates the internal surfaces of the lower chamber 103 to destroy microbial DNA and eliminate pathogens. The sterilization cycle is timed and controlled by the microcontroller to ensure thorough disinfection without overheating. A reflective inner coating within the chamber maximizes UV exposure, while sensors may optionally verify sterilization completion. This process ensures hygienic readiness for the next beverage cycle.

[0056] A pressure sensor (not shown in figure) is integrated with the handle 105 to monitor user’s grip strength on the handle 105 in real time. The microcontroller continuously monitors input from the pressure sensor, the pressure sensor used herein is preferably a force-sensitive resistor (FSR) embedded within the handle 105 to track the user's grip strength in real time. When the user holds the handle 105, the FSR detects pressure through changes in resistance. These changes are converted into analog signals and then digitized for analysis by the microcontroller.

[0057] In an embodiment of the present invention, the alert is generated through a speaker installed on the handle 105 to remind the user to hold the body 101 more firmly when grip becomes too loose or weak. The speaker works by converting the electrical signal into the audio signal. The speaker consists of a cone known as a diaphragm attached to a coil-shaped wire placed between two magnets. When the electric signal is passed through the voice coil, it generates a varying magnetic field that interacts with the magnet causing the diaphragm to move back and forth. This movement pushes and pulls air creating sound waves just like the electrical signal received and used alerting the user to hold the body 101 more firmly, when grip becomes too loose or weak.

[0058] A gyroscopic sensor (not shown in figure) is integrated with the body 101 to detect angular motion of the body 101. The microcontroller continuously monitors input from the gyroscopic sensor to detect any angular motion or tilt of the device body 101. The gyroscopic sensor, typically a MEMS (Micro-Electro-Mechanical Systems) device, measures angular velocity across multiple axes (pitch, roll, and yaw). These analog signals are converted into digital values using an on-board ADC (Analog-to-Digital Converter) and transmitted to the microcontroller. The microcontroller analyses these signals to detect abnormal tilts, falls, or rotations beyond a predefined threshold.

[0059] Upon detecting such motion, the microcontroller actuates the lid 104 to slide out via a drawer arrangement and close tightly to prevent spillage of the beverage. The drawer arrangement comprises of two plates which are connected through a slider. The slider consists of a sliding rail and a motorized slid able member connected to the sliding rail. The motorized slid able member is attached to the opening carved on the lid 104 and further to a motor which provides movement to the member in a bi-directional manner and movement to the plates. This way the drawer arrangement expands/contracts to close tightly the lid 104 in order prevent spillage of the beverage.

[0060] A Light Emitting Diode (LED) display 113 is positioned on the external surface of the body 101 and functions as the primary interface for real-time user communication. The LED 113 continuously presents information related to the current beverage status, operational activities of the device, and user-specific customization settings, enabling the user to monitor and interact with the device efficiently.

[0061] The Light Emitting Diode (LED) display 113 as mentioned herein is typically an LCD (Liquid Crystal Display) screen that presents output in a visible form. The screen is equipped with touch-sensitive technology, allowing the user to interact directly with the display using their fingers. A touch controller IC (Integrated Circuit) is responsible for processing the analog signals generated for user, providing continuous updates on beverage status, device operations, and personalized settings. The touch controller is typically connected to the microcontroller through various interfaces which may include but are not limited to SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit).

[0062] Lastly a battery (not shown in figure) is installed within the device which is connected to the microcontroller that supplies current to all the electrically powered components that needs an amount of electric power to perform their functions and operation in an efficient manner. The battery utilized here, is generally a dry battery which is made up of Lithium-ion material that gives the device a long-lasting as well as an efficient DC (Direct Current) current which helps every component to function properly in an efficient manner. As the device is battery operated and do not need any electrical voltage for functioning. Hence the presence of battery leads to the portability of the device i.e., user is able to place as well as moves the device from one place to another as per the requirements.

[0063] The present invention works best in the following manner, where the hollow body 101 as disclosed in the invention is divided into the upper and lower chambers 102, 103 for customized beverage processing. The upper chamber 102 stores the base beverage and is sealed with the spill-proof lid 104 featuring the airtight silicone gasket to prevent leaks during movement. The handle 105 is fixed through the gimbal arrangement 106, allows the device to pivot and maintain upright orientation regardless of the user's motion. The solenoid valve 107 positioned at the bottom periphery of the upper chamber 102 enables controlled flow of the beverage into the lower chamber 103 when actuated by the microcontroller. The additive containers 108 are arranged around the outer edge of the upper chamber 102, each containing health-based additives. These containers 108 are connected to the solenoid valve 107 via conduits 109, and each is integrated with the level sensor.

[0064] In continuation with these sensors detect the volume of additives and dispense them based on the user’s health data processed by the microcontroller. Inside the lower chamber 103, the mixing impeller 110 blends the base beverage with additives. The RPM sensor linked to the impeller 110 regulates its speed according to the volume of liquid and amount of additives. The Peltier-based thermal unit installed in both chambers adjusts temperature as per user preference using feedback from integrated temperature sensors. The fingerprint authentication module 112 identifies the user and retrieves from stored profile containing temperature, flow, and additive preferences. The LED 113 display provides real-time updates on beverage status and device activity. The pressure sensor on the handle 105 detects grip strength and issues alerts, when necessary, while the gyroscopic sensor detects tilting or falling motion and triggers lid 104 closure through the drawer arrangement. The UV sterilization unit activates post-beverage dispensing to disinfect the lower chamber 103, ensuring hygiene for the next use.
