Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wearable device provides multiple functions (lighting, sensing, driving), then user interaction and safety are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functional modules (driving module, sensor module, lighting module, control module) into a single wearable device system. The control module integrates the functions of detecting exercise start, selecting LED lamps based on exercise intensity, determining blinking periods based on walking speed, and controlling the lighting module, thereby resolving the contradiction by merging multiple functions into a unified system.
Solution Approach 2:
The wearable device is designed with multi-functionality, where the lighting module serves both as a communication interface (blinking patterns indicating exercise status, suspension, resumption) and as a safety feature (providing illumination). The control module universally manages multiple operations including exercise detection, LED selection, blinking period determination, and lighting control,实现ing one component performing multiple functions.
2Loss of information
If the device provides real-time feedback through LED blinking, then user interaction is improved, but energy consumption increases
Solution Approach 1:
The lighting module operates by blinking LED lamps periodically rather than continuous illumination. The control module determines a blinking period based on walking speed and controls the lighting module to blink at this determined period. This periodic action provides real-time feedback information while significantly reducing energy consumption compared to continuous operation.
Solution Approach 2:
The device changes operational parameters dynamically: the control module selects different LED lamps based on exercise intensity, determines blinking periods based on walking speed, and adjusts blinking patterns based on exercise status (normal, suspension, resumption). These parameter changes optimize the balance between providing sufficient feedback information and minimizing energy consumption.

AI summary
A wearable walking assist and/or exercise device may detect a start of exercise of the user, select LED lamps to be blinked from the plurality of LED lamps included in the lighting module based on an exercise intensity of the wearable device, determine a blinking period of the selected LED lamps based on a walking speed of the user, and blink the selected LED lamps for the determined blinking period.
