Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple coils are used in conventional close-coupled wireless communication systems, then reliable communication can be established, but the device complexity and constraint on positional relation increase
Solution Approach 1:
The patent implements dynamic antenna switching capability where the second electronic circuit device can switch between multiple second antennas based on communication requirements. The connection switching unit dynamically connects or disconnects second antennas to the second electronic circuit, allowing the system to adapt to different positional relations and maintain reliable communication without fixed coil arrangements
Solution Approach 2:
The patent divides the wireless communication function into multiple independent antenna units. The second electronic circuit device includes multiple second antennas that can be independently connected or disconnected from the second electronic circuit through the connection switching unit, allowing selective activation of communication functions based on operational needs
2Reliability
If multiple coils are used to ensure proper signal transmission and reception, then communication function is reliable, but the number of components and device complexity increase
Solution Approach 1:
The system dynamically switches between multiple second antennas based on communication needs rather than using all antennas simultaneously. The connection switching unit enables or disables specific antenna connections to the second electronic circuit, reducing the effective number of active components while maintaining communication reliability
Solution Approach 2:
Multiple second antennas are designed with universal functionality to perform both transmission and reception tasks. Any of the multiple second antennas can be connected to the second electronic circuit to fulfill communication requirements, reducing the need for specialized dedicated transmit or receive coils
3Ease of manufacture
If fixed positional relation between devices is maintained, then coil alignment is simplified, but adaptability to different device configurations is reduced
Solution Approach 1:
The connection switching unit provides dynamic reconfiguration capability that allows the second electronic circuit device to adapt to different positional relations with the first electronic circuit device. Rather than requiring fixed alignment, the system can dynamically switch between different second antennas to maintain optimal communication based on relative device positions and orientations
Solution Approach 2:
The system changes the connection state parameter of antennas dynamically. By switching which second antennas are connected to the second electronic circuit, the system adapts to varying operational conditions and device configurations without requiring physical repositioning or realignment of components
