Engineering Contradiction Analysis
1Reliability
If traditional fixed strip line and movable strip line are used with small coupling spacing, then coupling efficiency is improved, but processing errors cause large gaps that deteriorate electrical performance
Solution Approach 1:
The coupling structure is divided into multiple coupling surfaces (first coupling surface, second coupling surface, third coupling surface) distributed across different locations. This segmentation ensures that even if processing errors affect one coupling interface, other coupling surfaces maintain adequate coupling between the fixed strip line and movable strip line, thereby stabilizing electrical performance against manufacturing variations.
Solution Approach 2:
The coupling between strip lines is extended from a single-plane arrangement to a three-dimensional configuration with coupling surfaces at multiple heights and positions. The fixed strip line and movable strip line are coupled through multiple surfaces located at different vertical levels, transforming a one-dimensional coupling problem into a multi-dimensional solution that compensates for processing errors in any single dimension.
2Reliability
If crimping modules are added to maintain small coupling spacing, then electrical performance is improved, but device complexity and cost increase
Solution Approach 1:
The fixed strip line and movable strip line are designed with self-coupling capabilities through multiple coupling surfaces that automatically maintain adequate coupling spacing without requiring external crimping modules. The structure itself provides the coupling function through its geometric design, eliminating the need for additional fastening components and reducing overall device complexity.
Solution Approach 2:
The coupling function is merged into the basic structural design of the strip lines themselves. The fixed strip line and movable strip line are configured with integrated coupling surfaces that perform both structural support and signal coupling functions simultaneously, eliminating the need for separate crimping modules and simplifying the overall device architecture.
