Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless wearable speakers use internal batteries for power, then they provide wireless operation freedom, but they require removal and charging when batteries are drained, disrupting continuous use
Solution Approach 1:
The patent implements continuous power transfer through loop charging harnesses that maintain electrical connection during wear. The system provides uninterrupted power supply by transferring charge through the harnesses from an external power source, eliminating the need to stop and charge the device, thus maintaining continuous useful action of audio playback
Solution Approach 2:
The loop charging harnesses act as an intermediary component between the external power source and the earbud battery. This mediator enables simultaneous wireless audio operation and battery charging by providing an alternative power transfer path that doesn't interrupt the wireless audio function
2Duration of action of moving object
If wired wearable speakers are used, then continuous power supply is achieved, but the wire becomes entangled and pulls the device away from ears
Solution Approach 1:
The loop charging harnesses serve as an intermediary that provides the benefits of wired power transfer while eliminating the drawbacks of traditional wires. The harness design allows flexible positioning and reduces tangling issues while maintaining continuous power supply to the earbuds
Solution Approach 2:
The charging system incorporates dynamic adjustment capabilities where the loop harnesses can be positioned and adjusted to fit various charging arm styles and user preferences. The system adapts to different wear conditions while maintaining electrical connection, providing both continuous power and comfort
