Solution Overview
Problem
Existing connector technologies do not effectively suppress impedance mismatch on the plug type connector side, which is not addressed by existing mechanisms.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If contacts are formed with curved inverted portions to provide flexibility and connection, then the connector can absorb attachment position errors, but impedance mismatch occurs between the curved portion and linear portions
Solution Approach 1:
The patent applies local quality by making only specific portions of the contact linear (the portions that contribute to signal transmission) while keeping other portions curved for flexibility. This selective linearization ensures that the impedance-critical sections maintain consistent impedance, while the curved portions provide mechanical compliance without affecting electrical performance.
Solution Approach 2:
The contact is segmented into distinct functional portions: linear portions for impedance-matched signal transmission and curved portions for mechanical flexibility. This segmentation allows each portion to optimize its specific function without compromising the other, resolving the contradiction between adaptability and impedance consistency.
2Manufacturing precision
If partition members are added between contacts to suppress impedance mismatch, then impedance homogeneity is improved, but device complexity increases
Solution Approach 1:
The patent extracts the impedance-control function from a separate partition member and integrates it directly into the contact structure itself. By forming the linear portions as integral parts of the contact, the design eliminates the need for additional partition members while achieving the same impedance homogeneity effect.
Solution Approach 2:
The patent merges the mechanical connection function and the impedance control function into a single integrated contact structure. The linear portions of the contact simultaneously provide both structural connectivity and impedance matching, eliminating the need for separate partition members and reducing overall device complexity.
3Manufacturing precision
If existing impedance control mechanisms are used on socket type connectors, then impedance mismatch is suppressed on the socket side, but the plug type connector side remains unaffected
Solution Approach 1:
The patent creates a universal impedance control solution that can be applied to both socket-type and plug-type connectors through the same contact design principles. The linear portion configuration in the plug unit mirrors the impedance control approach used in socket connectors, ensuring consistent impedance performance across both connector types and enabling reliable high-speed differential transmission throughout the entire connection interface.
