Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless power transmission is implemented without communication capability, then power transmission can be achieved, but device identification and power control become difficult
Solution Approach 1:
The patent combines power transmission and communication functions into a single wireless power signal. Data packets are modulated onto the power transmission carrier wave, allowing the wireless power transmitter to send device identification and control information to receivers, and enabling receivers to send response packets back to transmitters, thus achieving bidirectional communication within the power transmission framework.
2Adaptability or versatility
If data packets are modulated into wireless power signals, then two-way communication is enabled, but system complexity increases
Solution Approach 1:
The wireless power signal serves multiple functions simultaneously: it transmits power to electronic devices and carries bidirectional communication data. The same carrier wave and signal pathway are used for both power delivery and information exchange, eliminating the need for separate communication hardware and reducing overall system complexity despite the added modulation capability.
