Engineering Contradiction Analysis
1Reliability
If a radio frequency connector uses a simple structure without additional shielding components, then the device complexity is low, but electric field leakage and signal interference occur, worsening the shielding performance
Solution Approach 1:
The shielding structure is divided into multiple segments: first shielding spacer, second shielding spacer, first shielding housing, second shielding housing, and shielding enhancement housing. Each segment performs a specific shielding function, and together they form a complete shielding system that effectively blocks electric field leakage and signal interference.
Solution Approach 2:
The shielding components are nested within each other to form multiple shielding spaces. The first and second shielding spacers are nested within the first and second shielding housings, which are in turn nested within the shielding enhancement housing, creating a multi-layered shielding structure that maximizes shielding effectiveness.
2Volume of moving object
If signal terminals are placed close together to reduce device size, then the compactness improves, but signal interference between adjacent terminals increases
Solution Approach 1:
Shielding spacers are positioned between adjacent signal terminals to divide the internal space into separate shielding regions. This segmentation allows signal terminals to be placed closer together while maintaining electrical isolation through the shielding partitions, thus reducing signal interference without increasing overall connector size.
Solution Approach 2:
The shielding spacers provide localized shielding exactly where needed - between adjacent signal terminals. This local shielding approach targets the specific areas where signal interference occurs, allowing compact terminal arrangement while maintaining signal integrity through localized electromagnetic field control.
3Reliability
If traditional shielding structures are used, then the manufacturing process is simple, but electric field leakage occurs, worsening the shielding effectiveness
Solution Approach 1:
The nested shielding structure consists of multiple housings and spacers fitted within each other, forming a complete shielding system. This nested design, while providing superior shielding effectiveness, can be manufactured as integrated components or pre-assembled units, balancing manufacturing complexity with performance requirements.
Solution Approach 2:
The shielding enhancement housing merges multiple shielding functions into a single integrated component that encompasses the first and second shielding housings. This consolidation simplifies the assembly process by reducing the number of separate shielding components that need to be handled and installed individually.
