Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If terminal devices only function as receiving ends for wireless charging, then the charging system is simple, but the flexibility and convenience are reduced due to requiring an external charging base
Solution Approach 1:
The terminal device is designed with both receiving coil and transmitting coil, enabling it to function as both a wireless charging receiver and transmitter. This multi-functionality allows the device to charge itself or charge other devices without requiring an external charging base, thereby improving flexibility and adaptability while maintaining reasonable device complexity through integrated circuit design.
2Ease of operation
If terminal devices only receive wireless charging signals, then the device structure is simple, but the convenience is reduced due to needing to carry a charging base
Solution Approach 1:
By equipping the terminal device with both receiving and transmitting wireless charging capabilities, the device can serve multiple purposes: self-charging, charging other devices, and eliminating the need to carry a separate charging base. This universal functionality significantly improves ease of operation and convenience.
Solution Approach 2:
The terminal device can charge itself wirelessly by receiving signals and can also provide wireless charging to other devices. This self-service capability eliminates the need for external charging equipment, making the device more convenient to use without requiring additional accessories.
3Adaptability or versatility
If the terminal device includes both receiving and transmitting coils, then flexibility is improved, but the device complexity increases
Solution Approach 1:
The terminal device integrates both receiving and transmitting wireless charging functions, allowing it to adapt to different charging scenarios. The device can switch between receiving mode and transmitting mode as needed, providing high flexibility for various use cases such as self-charging or charging other devices.
