Engineering Contradiction Analysis
1Reliability
If the FPC is made into a strip shape with various corners to implement electrical connections between different regions, then the electrical connection function is achieved, but the overall structure becomes complex and irregular, reducing assembling operability and efficiency
Solution Approach 1:
The patent divides the complex FPC structure into multiple simple strip-shaped FPCs (first FPC, second FPC, etc.) that extend in different directions. Each strip-shaped FPC has a simple linear structure without complex corners, and they are connected through connection components to achieve the electrical connection function while maintaining structural simplicity and ease of assembly
2Reliability
If the FPC is made into a strip shape with various corners to implement electrical connections between different regions, then the electrical connection function is achieved, but manual arrangement and coordination are required, reducing assembling efficiency
Solution Approach 1:
The patent segments the FPC into multiple independent strip-shaped components that can be assembled separately without requiring complex manual arrangement and coordination. The connection components enable straightforward assembly procedures, improving assembling efficiency while achieving the electrical connection function
Solution Approach 2:
The patent introduces connection components as intermediaries to connect the strip-shaped FPCs. These connection components simplify the assembly process by providing standardized interfaces, eliminating the need for complex manual arrangement and coordination, and enabling efficient assembly operations
3Reliability
If the FPC is made into a strip shape with various corners to implement electrical connections between different regions, then the electrical connection function is achieved, but it is not convenient for the implementation of circuit assembling
Solution Approach 1:
The patent divides the circuit board into multiple simple strip-shaped FPCs that are easier to manufacture and assemble compared to a single complex FPC with various corners. The segmented structure allows for simpler manufacturing processes and more convenient circuit assembling operations while maintaining the electrical connection function through connection components
