Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electrical connector design is used, then structural simplicity is maintained, but signal interference between terminals occurs affecting high-frequency performance
Solution Approach 1:
A shielding member is introduced as an intermediary element between terminal modules to block electromagnetic interference. The shielding member includes a grounding contact that connects to ground, creating a Faraday cage effect that prevents signal interference between adjacent terminals while maintaining high-frequency performance.
Solution Approach 2:
The connector is segmented into distinct functional zones with terminal modules separated by the shielding member. This segmentation isolates adjacent terminals electrically, preventing crosstalk and signal interference while allowing each terminal to function independently at high frequencies.
2Reliability
If shielding member is added to reduce signal interference, then high-frequency performance is improved, but manufacturing complexity increases
Solution Approach 1:
The shielding member is integrated with the insulative housing as a single molded component rather than a separate assembly. This merging of functions reduces the number of assembly steps, eliminates the need for separate grounding wire installation, and simplifies manufacturing while maintaining the shielding effect.
Solution Approach 2:
The insulative housing serves multiple functions: providing structural support, electrical insulation, and integrating the shielding member with grounding capability. This multi-functionality reduces the total component count and simplifies the manufacturing process while achieving signal interference protection.
