Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate NFC card reader and NFC tag IC are installed for data transmission, then data transmission function is achieved, but device complexity increases and installation becomes cumbersome
Solution Approach 1:
The patent combines power supply signal transmission and data transmission into a single wireless signal channel. The transmitting terminal modulates data onto the power supply signal, and the receiving terminal demodulates the data from the received signal, eliminating the need for separate NFC components and simplifying the overall system architecture.
Solution Approach 2:
The wireless signal is designed to serve multiple functions simultaneously: it provides power supply to the receiving terminal while also carrying data transmission. This multi-functional approach replaces the traditional separate systems for power and data, reducing device complexity while maintaining both functions.
2Use of energy by moving object
If separate power sources are installed for transmitting and receiving terminals, then power supply function is achieved, but device complexity increases
Solution Approach 1:
The patent merges the power supply signal transmission with data transmission into a unified wireless communication system. The same signal path and processing circuits handle both power delivery and data communication, eliminating the need for separate power sources and reducing overall system complexity.
