BACKGROUND OF THE INVENTION

[0002] In laboratories, manufacturing facilities, and research institutions, the storage and handling of chemical substances is a critical process that requires utmost precision and safety. Traditionally, chemical containers are stored manually in cabinets or shelves, with labeling used to guide classification. However, such manual systems are prone to human error, mishandling, and improper categorization, which may lead to accidental mixing of incompatible chemicals, posing serious risks of fire, explosions, and toxic exposure. Additionally, unauthorized access to hazardous substances remains a major concern, with limited real-time monitoring of environmental conditions inside storage units.

[0003] Although modern storage cabinets offer features like ventilation and basic locking mechanisms, they lack automation, intelligent sorting, and real-time response capabilities. There remains a need for a device that is able to automatically detect, classify and store chemical containers based on their properties, while also maintaining optimal environmental conditions and ensuring secure, traceable access. The present invention addresses these issues by integrating automated handling, smart authentication, environmental monitoring, and safety control device within a single compact body to offer a comprehensive chemical storage and sorting solution.

DETAILED DESCRIPTION OF THE INVENTION

[0020] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting.

[0021] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0022] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0023] The present invention relates to a chemicals storage and sorting device that is configured to securely accommodate a wide variety of chemical containers and is further adapted to automatically detect, identify, classify, and allocate each container into an appropriate storage compartment based on predefined chemical properties such as flammability, reactivity, volatility and corrosiveness.

[0024] Referring to Figure 1, an isometric view of a chemicals storage and sorting device is illustrated, comprising a hollow elongated cuboidal body 101 utilized for storage of chemical bottle(s) installed with a hinged door 102, a touch display unit 103 provided on the body 101, an AI-powered imaging unit 104 positioned on the body 101, a fingerprint scanner 105 provided on the body 101, a rectangular panel 106 provided on the body 101, a motorized dual-axis slider 107 installed on ceiling section of the body 101, a scanning unit 108 attached with the slider 107, a cylindrical cam assembly 109 positioned in proximity to the rectangular panel 106 and configured with a clamp 110, a horizontal conveyor belt 111 positioned beneath the panel 106, a plurality of chemical-specific storage boxes 112 arranged along the horizontal conveyor belt 111, a centrally positioned vertical conveyor belt 113 arranged within a midsection the body 101, a movable plate 114 mounted on the vertical conveyor belt 113, a retractable conveyor assembly 115 installed within the body, a designated isolated storage units 116 installed inside the body 101, an air extraction unit 1 provided with the body 101, a gas filtration unit 118 connected to the air extraction unit 117 and a cryogenic storage unit 119 disposed in bottom section of the body 101.

[0025] The proposed device herein comprises of a hollow elongated cuboidal body 101 resembling a refrigerator profile is designed to house and organize multiple chemical bottles securely within the body 101 having several internal compartments, wherein the body 101 is constructed from chemically resistant and thermally insulated materials to ensure durability and safety during chemicals storage. A hinged door 102 is installed on the front side of the body 101, which opens similarly to the refrigerator door 102, providing easy access to the internal compartment.

[0026] A touch display unit 103 is mounted on the outer surface of the body 101 for receiving input commands of an individual regarding storing/ accessing chemicals within the body 101. The display unit 103 consists of multiple layers, including a transparent conductive layer such as indium tin oxide (ITO) coated glass, which forms the surface that users directly touch. Beneath the layer lies a grid of electrodes, typically made of a conductive material like copper or silver, arranged in rows and columns.

[0027] When the individual touches the display unit 103, the display unit 103 creates a measurable change in capacitance at the point of contact, altering the electrical field between the electrodes. This change is detected by the controller circuitry embedded within the display unit 103, which interprets the position and intensity of the touch. The controller then converts this data into digital signals representing user inputs, which are further processed by an inbuilt microcontroller linked with the display unit 103.

[0028] Upon processing the individual’s input commands, the microcontroller activates an AI-powered imaging unit 104 positioned over the body 101 and linked with a processor configured to perform facial recognition of the individual attempting to access the device. The imaging unit 104 comprises an image capturing arrangement that includes a set of high-resolution lenses configured to capture multiple images of the individual attempting to access the device. The captured images are stored within an internal memory of the imaging unit 104 in the form of optical data.

[0029] The processor embedded with artificial intelligence protocols, enables to analyze the optical data and extract relevant biometric information from the captured images. This processing involves identifying key facial landmarks and comparing them with pre-stored facial profiles of authorized personnel. Once the required data is extracted, it is converted into digital pulses and binary bits, which are subsequently transmitted to the microcontroller for individual authentication.

[0030] A fingerprint scanner 105 is provided on the body 101 to further authenticate the individual’s identity. The fingerprint scanner 105 used herein is a capacitive fingerprint scanner 105 which operates on the principle of measuring electrical charge differences to detect the unique ridge patterns of a fingerprint. The fingerprint scanner 105 comprises a sensing array made up of numerous tiny capacitor circuits, an analog-to-digital converter (ADC), a signal processor and a controller.

[0031] When the individual places their finger on the scanner’s 105 surface, the ridges of the fingerprint come into contact with the capacitor plates, while the valleys remain slightly above, causing a variation in capacitance values across the array. These differences in electrical charge are captured and converted into digital signals by the ADC. The signal processor then analyzes this digital data to extract key biometric features, such as ridge flow and minutiae points. The extracted features are sent to the controller, which compares them with stored templates in the database.

[0032] The fingerprint scanner 105 captures the unique biometric pattern of the user’s finger and transmits the data to the microcontroller for comparison against stored credentials. Unless both authentication parameters, facial and fingerprint are verified, the hinged door 102 of the device remains securely locked, thereby ensuring controlled and restricted access to the chemical storage compartment. If authentication is successful, the microcontroller actuates an electromechanical actuator such as a solenoid connected to the locking mechanism of the hinged door 102. Upon receiving this signal, the actuator retracts the lock, thereby unlocking the door 102 is done and allowing access to the chemicals storage compartment.

[0033] The electromechanical actuator, such as the solenoid operates on the principle of electromagnetism and comprises key components including a coil of insulated wire, a movable ferromagnetic plunger, a spring, and a housing. When the microcontroller sends an electrical activation signal to the solenoid, current flows through the coil, generating a magnetic field that pulls the plunger into the coil’s center.

[0034] This linear motion of the plunger overcomes the spring’s resistance and disengages the mechanical locking pin connected to the hinged door 102. Once the lock is retracted, the door 102 becomes free to open. When the current stops, the magnetic field collapses and the spring pushes the plunger back to its original position, re-engaging the lock and securing the compartment again.

[0035] The fingerprint scanner 105 and AI-powered imaging unit 104 collectively provide an advanced level of access security, ensuring that only authorized personnel is able to interact with the chemical storage device. Each time an individual gains access to the body 101, the device automatically logs the event into an onboard or cloud-synced database. The logged data includes the identity of the personnel authenticated via fingerprint and facial recognition, the exact timestamp of access, and detailed information about the chemical bottle(s) stored, retrieved, or relocated during that session. This logging process ensures complete traceability and accountability for every interaction with the device, thereby enhancing safety, compliance, and audit readiness in controlled chemical storage environments.

[0036] A rectangular panel 106 is provided on an inner lateral side of the body 101 and serves as the initial placement surface for accommodating chemical bottle(s) by the personnel. Positioned above this panel 106, on the ceiling section of the body 101, is a motorized dual-axis slider 107 is designed to facilitate accurate and controlled movement along both X and Y directions. Attached to this slider 107 via an extendable rod is a scanning unit 108, which is precisely maneuvered across the panel 106 area to approach and align with each chemical bottle.

[0037] The motorized dual-axis slider 107 consists of two axes of motion, typically arranged perpendicular to each other, allowing movement in both horizontal and vertical directions. The slider 107 is controlled by the microcontroller. At its core, the slider 107 consists of a stepper motor that drives the translation of the scanning unit 108 suspended from it. The microcontroller sends signals to the motorized slider 107, dictating the precise movements required for positioning the scanning unit 108 towards the chemical bottle.

[0038] The extendable rod is linked to a pneumatic unit, including an air compressor, air cylinders, air valves and piston which works in collaboration to aid in extension and retraction of the rod. The pneumatic unit is operated by the microcontroller. Such that the microcontroller actuates valve to allow passage of compressed air from the compressor within the cylinder, the compressed air further develops pressure against the piston and results in pushing and extending the piston.

[0039] The piston is connected with the rod and due to applied pressure the rod extends and similarly, the microcontroller retracts the rod by closing the valve resulting in retraction of the piston. Thus, the microcontroller regulates the extension / retraction of the rod for accurate positioning of the scanning unit 108 over the chemical bottle(s).

[0040] The microcontroller then activates the scanning unit 108 to scan a particular label reading over the chemical bottle. The scanning unit 108 operates on the principle of optical data acquisition and interpretation, utilizing a combination of a high-resolution image sensor, an illumination source and a decoding processor. When activated by the microcontroller, the illumination source uniformly lights up the chemical label to enhance visibility, and the image sensor captures the label’s visual information, including barcodes, QR codes, text or symbols.

[0041] This captured image is then processed by an integrated decoding processor that analyzes the visual patterns and extracts critical data such as chemical name, classification, and handling instructions. The extracted information is converted into digital signals and transmitted to the microcontroller, which uses the data to categorize the chemical and determine its designated storage location. The scanning unit’s 108 precise functioning ensures accurate identification and safe handling of chemicals.

[0042] A cylindrical cam assembly 109 is positioned adjacent to the rectangular panel 106, with a clamp 110 mounted on its end effector, configured to securely grasp and transport chemical bottles. The cylindrical cam assembly 109 is designed to facilitate both horizontal and vertical movement of the bottles, enabling accurate placement into designated storage boxes 112 located within the body 101, in accordance with the classification of each chemical. The cylindrical cam assembly 109 comprises a rotating cam shaft, end effector and the clamp 110 attached to the end effector.

[0043] When activated by the microcontroller, the cam shaft rotates according to a programmed motion profile, causing the follower to translate this rotational movement into controlled linear or oscillatory motion. The clamp 110, is securely fastened to the end effector, grips the chemical bottle positioned on the rectangular panel 106. As the cam rotates, the clamp 110 moves the bottle either horizontally or vertically, depending on the cam’s lobe design and axis of rotation. This movement enables accurate placement of the bottle into a pre-classified storage box 112 inside the body 101, ensuring that each chemical is stored in its appropriate compartment based on its handling and safety requirements.

[0044] A horizontal conveyor belt 111 is positioned beneath the panel 106 and is adapted for the initial placement and categorization of chemical containers. Along this horizontal conveyor belt 111, multiple chemical-specific storage boxes 112 are arranged, with each box 112 is designed to hold a particular class of chemical based on predefined classification and handling criteria. The horizontal conveyor belt 111 operates on the principle of electromechanical motion, comprising components such as a continuous belt loop, a pair of rotating pulleys (one powered and one idle), an electric motor, rollers, and a frame structure.

[0045] The motor, controlled by the microcontroller, drives the powered pulley, which in turn moves the belt loop across the rollers, enabling smooth linear motion along a horizontal axis. Storage boxes 112 placed on the belt are transported with precision as the belt moves, while sensors may be integrated along the path to detect the position of the boxes 112 for timely actuation. The movement is regulated to align selected storage boxes 112 with the vertical conveyor belt 113 positioned centrally in the housing, thus enabling accurate handoff for further vertical transport.

[0046] A movable plate 114 is mounted on the vertical conveyor belt 113 using a motorized hinge, which is designed to rotate and pivot the plate 114 laterally according to the desired alignment direction. The motorized hinge comprises of a pair of leaf that is screwed with the surfaces of the plate 114. The leaf is connected with each other by means of a cylindrical member integrated with a shaft coupled with a DC (Direct Current) motor to provide required movement to the hinge.

[0047] The rotation of the shaft in clockwise and anti-clockwise aids in opening and closing of the hinge respectively. Hence the microcontroller actuates the hinge that in turn provides controlled angular displacement of the plate 114 to the left or right. This precise angular adjustment ensures that the storage box 112 placed on the plate 114 is properly aligned with the panel 106 holding the categorized chemical bottle. Once alignment is achieved, the cam assembly 109 is actuated to gently push the chemical bottle into the correctly positioned storage box 112.

[0048] A retractable conveyor assembly 115 is connected to the microcontroller and is configured to relocate the loaded storage box 112 into a designated isolated storage unit 116 installed within the body 101. The retractable conveyor assembly 115 operates on the principle of linear actuation and guided motion, and comprises components such as motor-driven rollers, telescopic frame segments and guide rails. When the microcontroller sends a signal, an electric motor powers the conveyor rollers to initiate movement, while telescopic segments extend or retract the conveyor’s length to reach specific storage locations and the guide rails ensure stable linear motion.

[0049] Once the loaded storage box 112 is positioned correctly, the motor halts the movement and, if needed, the conveyor retracts automatically. This coordinated actuation allows the retractable conveyor assembly 115 to securely and accurately transport chemical storage boxes 112 into isolated compartments based on classification, maintaining safety and efficiency.

[0050] Each isolated storage units 116 is spatially separated from the others using insulating and non-reactive paneling, which serves to prevent any physical or chemical interaction between incompatible substances. These storage units 116 are specifically designed to house only compatible chemical classes, ensuring that flammable materials are kept at a safe distance from corrosive or reactive agents. This arrangement minimizes the risk of hazardous reactions, enhances containment integrity, and maintains a controlled environment suitable for the safe storage of sensitive chemicals.

[0051] A sensing module comprises a gas and vapor detection sensor integrated within each storage units 116 is activated by the microcontroller to monitor the internal atmosphere for traces of harmful, flammable, corrosive, or volatile vapors. The gas and vapor detection sensor operates by using a chemically sensitive layer or semiconductor material that changes its electrical resistance in the presence of specific gas molecules. This change is translated into an electrical signal, which is sent to the microcontroller for evaluation. If the detected levels exceed predefined safety thresholds, the microcontroller instantly activates an air extraction unit 117 provided with a rear portion of the body 101 to neutralize and remove hazardous fumes from the storage units 116.

[0052] The air extraction unit 117 works on the principle of forced ventilation and includes components such as an exhaust fan, motor, air filters and connected ducts. When the microcontroller receives a signal indicating the presence of harmful or volatile vapors, it activates the motor, which in turn powers the exhaust fan. This fan generates airflow that pulls contaminated air from within the storage units 116.

[0053] As the air moves out, it passes through filters such as activated carbon or chemical absorbents that neutralize or capture harmful particles. Once filtered, the cleaned air is expelled through the outlet, effectively removing hazardous fumes from the storage environment and ensuring safe internal conditions.

[0054] A refrigeration control module is connected to the microcontroller, and is configured to autonomously regulate the internal cooling conditions of the body 101. Based on temperature readings received from internal sensors, the microcontroller sends commands to the control module, which in turn adjusts the operation of the refrigeration components such as the compressor, evaporator fan, and expansion valve to either increase or decrease cooling intensity.

[0055] The refrigeration control module operates based on a feedback unit that involves a network of internal temperature sensors, humidity sensors and key refrigeration components such as the compressor, evaporator fan and expansion valve. The temperature sensor embedded within the internal surface of each storage units 116 typically operates using a thermistor or resistance temperature detector (RTD) as its core sensing element.

[0056] These components exhibit a predictable change in electrical resistance relative to temperature variations. As the surrounding temperature fluctuates, the resistance of the sensing element alters accordingly. This change is converted into a voltage signal through an analog-to-digital converter and transmitted to the microcontroller. The microcontroller interprets this signal to determine the real-time internal temperature of the storage units 116.

[0057] The humidity sensor within each storage units 116 commonly consists of a hygroscopic dielectric material sandwiched between two electrodes. This material absorbs moisture from the surrounding air, causing a change in its capacitance or resistance depending on the sensor type (capacitive or resistive). This variation is proportional to the relative humidity in the environment. The sensor converts this change into an electrical signal that is relayed to the microcontroller. The microcontroller evaluates the humidity data.

[0058] When the temperature sensors and humidity sensors detect a deviation from the desired temperature range, they transmit this data to the microcontroller, which processes the information and sends appropriate control signals to the refrigeration control module. The module then modulates the functioning of the compressor to regulate refrigerant flow, adjusts the evaporator fan speed for efficient air circulation, and controls the expansion valve to manage refrigerant pressure and temperature. Together, these components maintain the required internal cooling conditions within the body 101 to ensure optimal storage of chemicals.

[0059] A gas filtration unit 118 is operatively connected to the air extraction unit 117 and is designed to purify the extracted air by removing hazardous substances before it is released or recirculated. The gas filtration unit 118 comprises at least one activated carbon filter and one HEPA (High-Efficiency Particulate Air) filter arranged in series. As air containing chemical vapors, odors, and fine particulates is drawn into the unit, it first passes through the activated carbon filter. This filter relies on the principle of adsorption, wherein gas molecules adhere to the porous surface of activated carbon due to Van der Waals forces, effectively trapping volatile organic compounds and chemical fumes.

[0060] After vapor removal, the air then flows through the HEPA filter, which functions on the principle of mechanical filtration. The densely packed fibers in the HEPA filter trap particles through diffusion, interception, and impaction mechanisms, efficiently capturing particulates as small as 0.3 microns. Together, these components enable the gas filtration unit 118 to comprehensively remove harmful gases and particulates, ensuring safe air release.

[0061] A cryogenic storage unit 119 is positioned at the bottom section of the body 101 and is structurally enclosed with high-efficiency thermal insulation to minimize heat exchange with the surroundings. Surrounding the cryogenic storage unit 119 is a liquid nitrogen coiling unit, which operates by continuously circulating liquid nitrogen through a network of coils wrapped around the storage chamber.

[0062] The circulation of liquid nitrogen, which has an extremely low boiling point, rapidly absorbs ambient heat and maintains the internal environment at sub-zero temperatures well below the freezing point. This principle relies on the latent heat absorption capacity of liquid nitrogen, ensuring that the stored chemical substances remain in a cryogenically stable state. The combination of thermal insulation and active liquid nitrogen circulation enables the cryogenic storage unit 119 to preserve sensitive materials that require ultra-low temperature conditions.

[0063] The present invention works best in the following manner, where the hollow elongated cuboidal body 101 is utilized for storage of chemical bottle(s), installed with the hinged door 102 resembling profile of the refrigerator. The touch display unit 103 is provided on the body 101 which receives voice commands from the authorized individual for storing or accessing chemicals within the body 101. The individual is authenticated using the fingerprint scanner 105 and the imaging unit 104, where the fingerprint scanner 105 captures unique biometric patterns while the imaging unit 104 performing facial recognition using captured optical data processed through artificial intelligence protocols. Only when both fingerprint and facial profiles match with those stored in database, the microcontroller generates an activation signal for an electromechanical actuator to retract the locking mechanism and unlock the hinged door 102. The user then places chemical bottles over the internal rectangular panel 106, from where the motorized dual-axis slider 107 moves the scanning unit 108 via extendable rod to read critical information from chemical labels. The scanning unit 108, once activated by the microcontroller, uses optical sensors to decode label data and transmits it for classification. Classified chemicals are directed onto the horizontal conveyor belt 111 beneath the panel 106, where the set of storage boxes 112 aligned along the belt receive specific classes of chemicals based on handling requirements. The chemical container is moved via cam assembly 109 with end effector clamp 110, supported by cylindrical cam for precise vertical and horizontal positioning. Once aligned, the box 112 is shifted on the vertical conveyor belt 113, where the motorized hinged plate 114 pivots to align it with isolated storage units 116. The retractable conveyor relocates the loaded box 112 to the insulated unit. Each unit is embedded with gas, temperature and humidity sensors, continuously monitored by the microcontroller. If hazardous vapors are detected, the air extraction unit 117 is activated, and extracted air passes through gas filtration unit 118 with HEPA and activated carbon filters to remove particulates and vapors. Cooling is maintained by refrigeration and cryogenic modules for safety.
