Engineering Contradiction Analysis
1Reliability
If conventional contact modules use two conductors in one component with separate dielectric and shielding parts, then electrical shielding can be provided, but the manufacturing and assembly processes become complex
Solution Approach 1:
The patent merges the shielding housing and dielectric insulator into a single integrated component. The shielding housing is formed as one piece that directly surrounds and integrates with the dielectric material, eliminating the need for separate assembly steps and reducing part count while maintaining shielding effectiveness.
Solution Approach 2:
The integrated shielding housing serves multiple functions simultaneously: it provides electromagnetic shielding, acts as the dielectric insulator, provides mechanical support, and guides the contact elements. This multi-functionality reduces the number of components needed and simplifies the overall structure.
2Reliability
If complex assembly processes are used to achieve good electrical shielding, then shielding performance is improved, but assembly ease deteriorates
Solution Approach 1:
By combining the shielding housing and dielectric insulator into a single integrated part, the assembly process is simplified. The contact elements are inserted directly into the integrated component without requiring separate assembly steps for shielding and insulation, making the process easier while maintaining shielding performance.
3Reliability
If multiple parts are used in the contact module, then shielding can be provided, but the number of parts increases complicating assembly
Solution Approach 1:
The patent reduces the number of parts by merging the shielding housing and dielectric insulator into a single integrated component. This eliminates the need for separate assembly of these parts while maintaining the shielding performance that would otherwise require multiple components.
Solution Approach 2:
The integrated shielding housing performs multiple functions in one component: electromagnetic shielding, electrical insulation, mechanical support, and contact element guidance. This multi-functionality reduces the total number of parts needed in the contact module.
