Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a circular cross-section cable is used, then electrical connectivity is maintained, but the thickness dimension becomes large
Solution Approach 1:
The cable cross-section is changed from a symmetric circular shape to an asymmetric flat structure where the thickness dimension is significantly reduced compared to the width dimension. This asymmetric geometry allows the cable to meet compact design requirements while maintaining electrical connectivity through the flattened configuration.
2Object-affected harmful factors
If shielding structure is added to protect against interference, then anti-interference capability is improved, but device complexity increases
Solution Approach 1:
The shielding structure is integrated with the cable assembly by combining the shielding shell with the connector housing. The shielding shell is formed as an integral part or closely coupled component with the insulative housing, eliminating the need for separate shielding components and reducing overall assembly complexity while maintaining effective electromagnetic interference protection.
3Shape
If asymmetrical shielding shells are used, then flat cable structure is achieved, but manufacturing precision requirements increase
Solution Approach 1:
The asymmetrical shielding shells are pre-assembled and pre-positioned during the manufacturing process before final cable assembly. The shells are configured in their correct asymmetric orientations and secured to the connector housing in advance, ensuring proper alignment and reducing the precision requirements during final assembly operations.
