Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an L-shaped conductive member is added to connect shield shells when connector direction is perpendicular to cable pull-out direction, then the connector can be mounted, but the shield current path length becomes longer and the number of components increases
Solution Approach 1:
The shield connector is divided into separate male and female shield shell portions that can be independently positioned and connected, allowing flexible mounting orientations without requiring additional L-shaped conductive members. The segmentation enables each portion to be optimized for its specific mounting direction.
Solution Approach 2:
The shield connector design transitions from a single-plane L-shaped connection to a three-dimensional coaxial connection structure, where the male and female shield shells connect along the same axis, eliminating the need for perpendicular L-shaped conductive members and reducing overall complexity.
2Adaptability or versatility
If an L-shaped conductive member is used to connect shield shells, then mounting flexibility is achieved, but shielding performance deteriorates due to longer shield current path length
Solution Approach 1:
The shield path is segmented into distinct male and female shield shell portions that connect coaxially, maintaining short current path length while providing mounting flexibility. Each segmented portion can be independently optimized for its mounting orientation.
Solution Approach 2:
Instead of using an L-shaped member that extends the shield path at right angles, the invention inverts the approach by using a straight coaxial connection where the shield current flows directly along the connector axis, minimizing path length while achieving the same mounting flexibility through the separate male and female portions.
3Adaptability or versatility
If multiple conductive members are added for connecting shield shells in perpendicular configuration, then mounting versatility is improved, but the operation of connecting components becomes more complex
Solution Approach 1:
The shield connector is segmented into male and female portions that can be independently installed in their respective mounting locations, then connected through a simple coaxial alignment process, reducing the complexity of connection operations compared to assembling multiple L-shaped conductive members.
Solution Approach 2:
The male and female shield shell portions serve dual functions: they provide the mounting interface for perpendicular cable pull-out directions and simultaneously create the coaxial shield connection path, eliminating the need for separate L-shaped conductive members and simplifying the overall connection operation.
