Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a metal cover is provided inside or outside the connector to play a shielding effect, then electromagnetic interference is reduced, but processing difficulty increases, cost increases, and assembly complexity increases
Solution Approach 1:
The patent combines the shielding function with the connector body by integrating a conductive layer directly into the connector structure. The conductive layer is formed on the inner surface of the first inner cavity and electrically connected to the shielding layer, merging the shielding function with the connector rather than using a separate metal cover component.
Solution Approach 2:
The patent extracts the shielding function from a separate metal cover component and integrates it directly into the connector structure through a conductive layer. This extraction eliminates the need for a distinct metal cover while maintaining the shielding effect.
2Object-affected harmful factors
If a metal cover is provided inside or outside the connector to play a shielding effect, then electromagnetic interference is reduced, but processing cost increases
Solution Approach 1:
The patent combines the shielding function with the connector body by integrating a conductive layer directly into the connector structure. The conductive layer is formed on the inner surface of the first inner cavity and electrically connected to the shielding layer, merging the shielding function with the connector rather than using a separate metal cover component.
Solution Approach 2:
The patent replaces the expensive metal cover with a more cost-effective conductive layer that can be formed through coating or plating processes. This substitution reduces material and processing costs while maintaining the essential shielding function.

If a metal cover is provided inside the connector, then shielding effect is achieved, but short circuit risk increases between metal cover and conductor core
Solution Approach 1:
The patent introduces an insulating layer as an intermediary between the conductive layer and the conductor core. The insulating layer is provided between the conductive layer and the conductor core to prevent direct contact and potential short circuits, while the conductive layer remains electrically connected to the shielding layer through the shielding device.
