Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart water bottles are cumbersome, prone to water exposure and damage, and inaccurately track water consumption due to inability to differentiate between drinking, pouring, and adding water.
Innovation Solution
A smart bottle holder with a weighing module, controller, and multi-axis accelerometer that detects movement and distinguishes drinking actions by analyzing weight changes and acceleration curves, allowing for accurate water consumption tracking and reminders without altering the bottle's structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a built-in function module is added to the water bottle for monitoring water consumption, then the water consumption monitoring function is improved, but the structure of the bottle becomes more complex and the volume increases
Solution Approach 1:
The system is divided into two independent parts: a simple bottle and a separate holder containing all electronic components (weighing module, controller, communication module). This segmentation allows the bottle to remain simple while the holder provides automated monitoring functions.
Solution Approach 2:
The holder acts as an intermediary device that contains all the electronic components needed for water consumption monitoring. Instead of embedding complex electronics in the bottle, the holder serves as a mediator that interfaces with the bottle to provide monitoring functions externally.
2Extent of automation
If a built-in function module is added to the water bottle for monitoring water consumption, then the water consumption monitoring function is improved, but the weight of the bottle increases
Solution Approach 1:
The heavy electronic components are segmented from the bottle and placed in the holder. The bottle itself remains lightweight, while the holder containing the weighing module and other electronics provides the monitoring functionality without adding weight to the bottle.
3Extent of automation
If the water bottle is made with a built-in function module for monitoring, then the water consumption monitoring capability is improved, but the waterproof performance and resistance to fall-off or hitting deteriorate
Solution Approach 1:
The bottle is kept simple and free of electronic components, maintaining its original waterproof and durable properties. The holder, which contains all electronics, is designed separately and attaches to the bottle, allowing the bottle itself to remain reliable for withstanding water exposure, falls, and impacts.
4Extent of automation
If water consumption is measured by detecting changes in water amount, then the monitoring function is achieved, but the accuracy of water consumption statistics deteriorates due to inability to recognize user actions
Solution Approach 1:
The controller receives feedback from both the weighing module (weight changes) and the wake-up module (movement detection). By combining these feedback signals, the controller can distinguish between drinking actions and other actions like pouring or adding water, thereby improving measurement accuracy.
Solution Approach 2:
The system replaces simple weight-based measurement with a more sophisticated detection system that uses acceleration sensors to detect movement patterns. This mechanical detection system allows the controller to recognize specific user actions and accurately calculate water consumption based on recognized drinking events.
