Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
State-of-the-art connectors face a trade-off between EMC tightness, insertion forces, and stability in high-frequency ranges, where optimizing one parameter often contradicts the others, leading to increased insertion forces and potential damage from mechanical forces.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a closed entry structure is used in the outer conductor, then EMC tightness is improved, but insertion forces increase significantly
Solution Approach 1:
The outer conductor is segmented into a base body with contact tabs and a separate outer conductor ring. The ring is attached to the base body to form a closed entry structure, but the segmentation allows the contact tabs to remain flexible while achieving EMC shielding through the closed ring structure.
Solution Approach 2:
The outer conductor ring is designed with at least one bulge or indentation that provides flexibility. This flexible structure allows the ring to deform during insertion, reducing insertion forces while maintaining the closed entry configuration for EMC tightness.
2Reliability
If a closed entry structure is used, then protection from mechanical forces is improved, but insertion forces increase
Solution Approach 1:
The outer conductor is divided into a base body and a separate ring structure. The ring provides protective enclosure for the contact tabs while the segmentation allows the contact tabs to flex independently, reducing insertion forces despite the closed protective structure.
Solution Approach 2:
The outer conductor ring incorporates bulges or indentations that create flexible regions. These flexible regions allow the ring to deform during insertion, reducing insertion forces while the closed ring structure continues to provide mechanical protection for the contact tabs.
3Ease of operation
If contact tabs are made flexible to reduce insertion forces, then ease of operation is improved, but stability in high frequency range may worsen
Solution Approach 1:
The outer conductor is segmented into flexible contact tabs on a base body and a separate outer conductor ring. This segmentation allows the contact tabs to be flexible for easy insertion while the complete closed ring structure provides stability for high-frequency performance.
Solution Approach 2:
The outer conductor ring with bulges or indentations acts as a flexible shell that can deform during insertion, reducing insertion forces. Once assembled, the ring maintains its structure to provide stability for high-frequency applications.
