Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NFC circuits or ICs are added at both transmitter and receiver sides for one-to-one communication, then communication reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the communication function from separate NFC circuits or ICs and integrates it into the existing wireless power transmission circuit. The transmitter and receiver use the same power transmission circuit for both power delivery and communication, eliminating the need for additional dedicated communication components.
Solution Approach 2:
The wireless power transmission circuit is designed to serve dual purposes: transmitting power and enabling communication. The same circuit that transmits power also carries communication signals, allowing one component to perform multiple functions and eliminating the need for separate communication hardware.
2Measurement precision
If NFC circuits or ICs are added for one-to-one communication, then communication accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The patent removes the requirement for additional NFC circuits or ICs by extracting the communication function from separate components and implementing it within the existing power transmission circuit, thereby reducing manufacturing costs while maintaining communication accuracy.
Solution Approach 2:
The patent merges the communication function with the power transmission function in a single circuit. By combining these functions, the system reduces the total number of components required, simplifying manufacturing and reducing costs while preserving accurate one-to-one communication capabilities.
