Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electrical connectors are used without partitioning members, then the device complexity is low, but crosstalk occurs between differential signal terminal pairs affecting signal transmission quality
Solution Approach 1:
The connector is divided into upper and lower terminal rows with a partitioning member positioned between them. This segmentation physically separates the differential signal terminal pairs, preventing electromagnetic interference and crosstalk between signals while maintaining organized signal routing.
Solution Approach 2:
A partitioning member serves as an intermediary element between the upper and lower terminal rows. This partitioning member includes grounding terminals that are electrically connected to ground, creating an electromagnetic shield that blocks interference between adjacent signal pairs.
2Reliability
If partitioning members are added to shield between terminal pairs, then crosstalk is reduced and signal transmission quality improves, but the device complexity increases
Solution Approach 1:
The partitioning member combines multiple functions into a single component: it provides physical separation between terminal rows, incorporates grounding terminals for electromagnetic shielding, and maintains structural support. This merging reduces the need for separate shielding components while achieving effective crosstalk reduction.
Solution Approach 2:
The partitioning member serves multiple purposes simultaneously: it acts as a physical barrier between signal pairs, provides grounding paths for electromagnetic interference, and maintains the structural integrity of the connector assembly. This multi-functionality justifies the added complexity by delivering multiple benefits from a single component.
3Reliability
If grounding terminals are electrically connected to the partitioning member, then electromagnetic shielding effectiveness is enhanced, but manufacturing complexity increases
Solution Approach 1:
The grounding terminals are integrated directly into the partitioning member structure, combining the shielding function with the partitioning structure. This integration eliminates the need for separate grounding components and reduces the number of assembly steps required to achieve effective electromagnetic shielding.
Solution Approach 2:
The partitioning member is designed to automatically provide grounding paths through its integrated grounding terminals. The structure itself serves the shielding function without requiring external grounding components or complex assembly procedures, making the manufacturing process simpler while maintaining shielding effectiveness.

Implementation Method 1
when the electromagnetic wave generated by the pair of first differential signal terminals and the pair of second differential signal terminals during signal transmission is absorbed by the partitioning member
