Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless charger supports multiple charging protocols (Qi and Powermat), then adaptability to different devices is improved, but device complexity increases
Solution Approach 1:
The charging module is divided into separate protocol-specific charging circuits (Qi charging circuit and Powermat charging circuit), each handling a specific wireless charging protocol. This segmentation allows the system to support multiple protocols while keeping each individual circuit relatively simple and well-defined.
Solution Approach 2:
The charging module is designed with multi-functionality to support both Qi and Powermat wireless charging protocols through a single unified interface. The module can automatically detect which protocol is needed and switch between different charging circuits accordingly, providing universal compatibility without requiring separate charging devices.
2Device complexity
If a wireless charger uses a single charging protocol, then device complexity is reduced, but adaptability to different devices deteriorates
Solution Approach 1:
The charging module incorporates dynamic switching capability between different wireless charging protocols. A control circuit automatically detects the device type and dynamically switches between Qi and Powermat charging circuits, allowing the system to adapt its behavior based on real-time requirements while maintaining a relatively simple underlying structure.
Solution Approach 2:
A control circuit acts as an intermediary between the device and the charging circuits. This intermediary detects the wireless charging protocol requirement and routes the charging process through the appropriate circuit, providing adaptability without requiring the user to understand or configure the complex internal structure.
