Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a grounding bar is added to improve connector performance, then signal transmission reliability is improved, but device complexity increases
Solution Approach 1:
The patent removes the grounding bar component from the connector structure, extracting the unnecessary element that was causing complexity while maintaining signal transmission reliability through optimized conductive terminal designs embedded in the insulating core
Solution Approach 2:
The patent changes the dimensional parameters of the conductive terminals, specifically setting the minimum width of the first embedded segment to 0.26-0.3mm and the maximum width of the first front extending portion to 0.34-0.38mm, which optimizes signal transmission without requiring additional grounding components
2Reliability
If conductive terminal dimensions are optimized, then transmission efficiency of high frequency signals is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent defines specific parameter ranges for the conductive terminals (embedded segment width: 0.26-0.3mm, front extending portion width: 0.34-0.38mm, contacting portion width: 0.23-0.27mm) that balance transmission efficiency with manufacturability, avoiding overly tight tolerances while achieving optimal signal performance
Solution Approach 2:
The patent applies different width dimensions to different segments of the conductive terminals (embedded segment, front extending portion, contacting portion), optimizing each local region for its specific function while maintaining overall transmission efficiency without requiring uniform high precision throughout the entire structure

AI summary
A transmission module of a high speed connector includes an insulating core and two rows of conductive terminals fixed to the insulating core and parallel to a width direction. Each of the conductive terminals includes an embedded segment fixed and embedded in the insulating core, a contacting segment, and a fixing segment, the latter two of which respectively extend from two opposite ends of the embedded segment. Each of the embedded segments has a minimum width within a range of 0.26-0.3 mm. Each of the touching segments includes a front extending portion having a maximum width within a range of 0.34-0.38 mm and a touching portion having a maximum width within a range of 0.23-0.27 mm. The embedded segments and the touching segments of one of the two rows of the conductive terminals are mirror-symmetrical to and face those of the other row of the conductive terminals.
