Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless charging coil communication protocol is used for authentication, then wireless power transmission can be established, but authentication speed and data transmission capability are limited
Solution Approach 1:
The patent divides the communication function into two separate circuits: the first communication circuit handles wireless power transmission using the coil, while the second communication circuit handles authentication and data transmission using a different frequency band. This segmentation allows each circuit to be optimized for its specific function, resolving the contradiction between reliable power transmission and fast authentication.
Solution Approach 2:
The patent introduces a second communication circuit as an intermediary for authentication purposes. This intermediary uses a different frequency band from the wireless charging coil, enabling authentication operations without interfering with the power transmission process and achieving both reliability and speed requirements.
2Reliability
If wireless charging coil communication protocol is used for authentication, then power transmission can be maintained, but data transmission amount and speed are insufficient
Solution Approach 1:
The communication functionality is segmented into two distinct circuits operating on different frequency bands. The first circuit maintains stable power transmission while the second circuit provides enhanced data transmission capabilities for authentication, thus resolving the contradiction between connection stability and data transmission capability.
Solution Approach 2:
The second communication circuit serves multiple functions including authentication, device identification, and data exchange, while the first communication circuit focuses on power transmission. This multi-functionality approach allows the system to maintain reliable power transmission while simultaneously achieving robust data transmission for authentication purposes.
