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 the processing difficulty and cost increase, and assembly labor-hours increase
Solution Approach 1:
The patent extracts the shielding function from the traditional metal cover structure and integrates it directly into the connector body through a conductive layer. This eliminates the need for a separate metal cover component while maintaining the electromagnetic shielding effect, thereby reducing processing difficulty and assembly complexity.
Solution Approach 2:
The conductive layer is merged with the connector body as an integrated structure, combining the connector function and shielding function into a single component. This merging eliminates the need for separate assembly steps and reduces overall device complexity while maintaining shielding effectiveness.
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 the assembly labor-hours increase
Solution Approach 1:
By merging the shielding function into the connector body through the conductive layer, the patent eliminates separate assembly steps for installing a metal cover. The conductive layer is formed as part of the connector manufacturing process, significantly reducing assembly labor-hours.
3Object-affected harmful factors
If a metal cover is provided inside the connector, then shielding effect is achieved, but short circuit may easily occur between the metal cover and the conductor core, causing the shielding layer to be damaged or even the cable to be burned
Solution Approach 1:
The patent introduces an insulating housing as an intermediary between the conductive layer (shielding structure) and the conductor core. This insulating housing prevents direct contact and potential short circuits while allowing the shielding function to operate effectively, thereby improving reliability.
4Device complexity
If the connector has no shielding device for shielding, then the structure is simple, but a large electromagnetic interference occurs at the location of the connector
Solution Approach 1:
The patent merges the shielding function into the connector body by forming a conductive layer as an integral part of the connector structure. This integration maintains structural simplicity while effectively reducing electromagnetic interference at the connector location.
