Liquid Dispenser User Identification for Accurate Hydration Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerator appliances with liquid dispensers lack accurate hydration tracking, requiring manual user input and often failing to differentiate between users consuming the dispensed water, leading to inaccurate recording of water consumption.
Innovation Solution
A method and system that includes a liquid dispenser with a flow meter and a controller to determine the user's identity through various means such as camera recognition, fingerprint scanning, or voice activation, and prompts the user to confirm the intended recipient of the dispensed liquid, allowing for accurate tracking and attribution of consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional refrigerator appliances notify users of water dispensed but require manual entry into separate applications, then users can track water consumption, but the tracking process becomes cumbersome and inaccurate
Solution Approach 1:
The system automatically performs the tracking function without requiring manual user intervention. The refrigerator appliance itself captures dispensing data through its integrated sensors and communication systems, then autonomously transmits this data to the user's mobile application, eliminating the need for manual entry while maintaining accurate tracking
Solution Approach 2:
The patent introduces an intermediary communication system (wireless transceiver and mobile application) that acts as a bridge between the refrigerator's dispensing mechanism and the user's tracking needs. This intermediary automatically processes and transmits dispensing data, resolving the contradiction by making the tracking process both accurate and effortless
2Measurement precision
If the system tracks water dispensed from the dispenser, then hydration monitoring is enabled, but it cannot differentiate between users consuming the water leading to inaccurate recording
Solution Approach 1:
The patent replaces manual user identification methods with automated biometric or digital recognition systems. Sensors such as fingerprint scanners, facial recognition cameras, or RFID readers automatically identify which user is accessing the dispenser, eliminating the need for manual input while achieving precise user-specific tracking
Solution Approach 2:
The system creates digital copies or profiles of multiple users and automatically matches dispensing events to the correct user profile through automated recognition. This allows the system to track consumption for each user independently without adding significant physical complexity to the dispenser mechanism
3Measurement precision
If automated user identification and confirmation prompts are implemented, then accurate hydration tracking is achieved, but the system complexity increases
Solution Approach 1:
The controller is designed to perform multiple functions: it manages the dispensing mechanism, identifies users through integrated sensors, displays confirmation prompts, and communicates with external devices. By making the controller multi-functional, the system achieves accurate tracking without proportionally increasing overall device complexity
Solution Approach 2:
The patent combines several subsystems (user identification, dispensing control, display interface, and wireless communication) into an integrated controller unit. This merging of functions reduces the number of separate components needed and simplifies the overall system architecture while maintaining accurate hydration tracking capabilities
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise tracking of liquid consumption by ensuring that each dispensation is correctly attributed to the intended user, enhancing user accountability and hydration monitoring within households or groups.
Implementation Method 1
a flow meter provided at the liquid dispenser, the flow meter detecting an amount of liquid dispensed from the liquid dispenser
Data Source
AI summary
A method of tracking liquid consumption includes receiving an input from a user to dispense liquid from a liquid dispenser, determining an identity of the user, determining a volume of liquid dispensed from the dispenser, and confirming that the correct user is consuming the dispensed liquid.
