Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional light-emitting elements are attached to wearable articles, then light emission function is achieved, but the structure lacks stretch resistance and pull resistance, causing breaking during cleaning or stretching
Solution Approach 1:
The power supply system is segmented into a rechargeable battery and a separate charging device, allowing the article to be washed without the charging cable while maintaining electrical connectivity through a connector during non-washing periods
Solution Approach 2:
The patent uses flexible printed circuit boards (FPC) to connect light-emitting elements to the power supply, allowing the circuit to bend and stretch with the wearable article without breaking, thus providing both stretch resistance and maintaining electrical connectivity
2Ease of operation
If wired charging is used for rechargeable batteries, then electrical power can be supplied, but spatial range is limited and convenience is reduced
Solution Approach 1:
The patent replaces the mechanical wired charging system with a wireless charging system using electromagnetic induction, where a charging device with a transmitter coil wirelessly transfers power to the rechargeable battery through a receiver coil, eliminating the need for physical cable connections and enabling charging without spatial constraints
Solution Approach 2:
The patent introduces an intermediary wireless charging system consisting of a transmitter circuit that converts power to AC signals and a receiver circuit that converts AC signals back to power, enabling wireless energy transfer between the charging device and the wearable article
3Reliability
If light-emitting structure is mounted on wearable articles, then nighttime atmosphere and aesthetics are improved, but water washing causes breaking of power supply wires
Solution Approach 1:
The power supply system is segmented into a rechargeable battery and a separate charging device, allowing the article to be washed without the charging cable while maintaining electrical connectivity through a connector during non-washing periods
Solution Approach 2:
The patent uses flexible printed circuit boards (FPC) to connect light-emitting elements to the power supply, allowing the circuit to bend and stretch with the wearable article without breaking, thus providing both stretch resistance and maintaining electrical connectivity
