Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a rigid conductive ring with regular hexagonal cross section is used to secure the cable, then the connector width can be reduced, but gaps are formed between the conductive ring and the circular cable that affect grounding and electromagnetic shielding
Solution Approach 1:
The patent replaces the rigid conductive ring with a flexible conductive elastomer that can deform to conform to the circular cable cross-section. This flexible material eliminates gaps between the connector and cable, ensuring complete contact for reliable grounding and electromagnetic shielding while maintaining the reduced connector width design.
Solution Approach 2:
The patent changes the physical state and properties of the conductive material from rigid to flexible/elastomeric. This parameter change allows the material to adapt its shape to fill gaps and achieve complete contact with the cable surface, resolving the contradiction between compact connector design and effective grounding.
2Ease of manufacture
If a rigid conductive ring is used, then manufacturing is simplified, but electromagnetic shielding and high-frequency transmission are degraded due to gaps
Solution Approach 1:
The flexible conductive elastomer is applied as a thin film or coating that conforms to the cable surface, providing continuous electromagnetic shielding without gaps. This approach maintains ease of manufacture through simple application processes while effectively blocking electromagnetic interference.
Solution Approach 2:
The patent uses composite conductive elastomeric materials that combine flexibility with high electrical conductivity. These composite materials provide both the mechanical compliance needed to eliminate gaps and the electrical properties required for effective electromagnetic shielding and high-frequency signal transmission.
3Ease of operation
If gaps exist between the conductive ring and cable, then assembly is easier, but signal integrity and grounding are compromised
Solution Approach 1:
The flexible conductive elastomer is designed to self-adjust and self-conform to the cable surface through elastic deformation. This self-service mechanism automatically eliminates gaps upon assembly without requiring precise alignment or additional adjustment steps, maintaining ease of assembly while ensuring complete contact for signal integrity.
