Pressure-Sensing Cup Support for Automatic Water Intake Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cups lack functionality to remind users of adequate water intake, as they do not provide drinking information or adapt to user behavior, leading to ineffective hydration reminders.
Innovation Solution
A measuring device with a first body supporting a cup, a second body that slides relative to the first, and pressure sensing components that calculate volume variation based on weight changes, allowing for precise water intake tracking and reminders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a regular cup is used, then it is simple and universally compatible, but it lacks functionality to provide drinking information and remind users of water intake
Solution Approach 1:
A measuring device is introduced as an intermediary component that wraps around or attaches to regular cups. This mediator contains the pressure sensing components and control unit, enabling drinking information provision without modifying the basic cup structure. The intermediary device bridges the gap between simple cups and intelligent monitoring requirements.
Solution Approach 2:
The measuring device is designed to be universally compatible with various cup types and sizes through adjustable components and flexible mounting mechanisms. It performs multiple functions including weight sensing, volume calculation, and reminder notifications, making a single device adaptable to different user needs and cup configurations.
2Adaptability or versatility
If specialized designed cups are used to remind users of drinking water, then drinking information provision is improved, but users seldom use them because they forget to bring the designed cup or it does not fit into their drinking behavior
Solution Approach 1:
The measuring device accommodates various cup types and drinking behaviors through adjustable components and flexible measurement algorithms. It adapts to different user routines whether drinking from a travel mug, coffee cup, or water bottle, eliminating the need for users to adopt specific drinking behaviors or carry specialized equipment.
Solution Approach 2:
The device automatically detects cup placement, initiates measurement, and provides reminders without requiring user intervention. The system self-activates when a cup is placed on the device, automatically tracks water intake, and sends notifications based on predefined hydration goals, reducing the cognitive load on users.
3Measurement precision
If pressure sensing components are disposed between the first body and the second body to sense weight, then measurement precision is improved, but the device complexity increases
Solution Approach 1:
Traditional complex mechanical weighing mechanisms are replaced with electronic pressure sensing components that convert force directly into electrical signals. This substitution maintains high measurement precision while reducing mechanical complexity, as the pressure sensors integrate seamlessly with the digital control system for automated calculation and display.
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
The device effectively tracks water intake in various cup positions, providing reminders for adequate hydration, adapting to most cups and user behaviors, thus enhancing hydration awareness.
Implementation Method 1
The at least one first pressure sensing component is disposed between the first body and the at least one second body for sensing weight of the cup and the liquid so as to generate a signal corresponding to the weight
Data Source
AI summary
A measuring device includes a first body, a second body slidably combined with the first body, a first pressure sensing component, and a control unit. The first body is for supporting a cup receiving liquid. The first pressure sensing component is disposed between the first body and the second body for sensing weight of the cup and the liquid and generating a signal corresponding to the weight. The control unit is electrically connected to the first pressure sensing component. The control unit determines a volume variation of the liquid according to a weight variation of the cup and the liquid calculated based on a difference between signals transmitted from the first pressure sensing component at different time points.
