Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wired audio device is used for FM radio receiving function, then the FM radio signal can be received and output, but the user's freedom of movement is restricted
Solution Approach 1:
The patent replaces the mechanical connection (wired audio device with physical cable) with a wireless communication system. The electronic device includes an FM radio receiving circuit that receives FM signals and transmits them wirelessly via Bluetooth to wireless audio devices, eliminating the need for physical cables and thereby restoring user mobility while maintaining FM radio functionality
2Ease of operation
If a wireless audio device is used, then user freedom of movement is improved, but the FM radio receiving function cannot be utilized directly
Solution Approach 1:
The electronic device is designed with multi-functionality, serving both as a wireless audio device case and as an FM radio receiver. The device includes an FM radio receiving circuit that can receive FM signals and transmit them to connected wireless audio devices, allowing the same device to provide both wireless audio playback and emergency FM radio functionality without requiring separate equipment
3Reliability
If an FM radio receiving coil antenna is added to the electronic device, then the FM radio receiving function is enabled, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single integrated device. The electronic device combines the wireless audio device case, wireless charging coil antenna, FM radio receiving coil antenna, and FM radio receiving circuit into one unified structure. This integration allows the device to provide wireless charging, wireless audio transmission, and FM radio reception capabilities simultaneously, reducing the need for separate devices and overall system complexity
