Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electromagnetic shielding members are formed on the insulating body or terminal module by means of secondary molding, then electromagnetic shielding performance is improved, but production complexity increases and replacement flexibility is reduced
Solution Approach 1:
The electromagnetic shielding member is separated from the insulating body and terminal module, becoming an independent component that can be assembled separately. This segmentation allows the shielding member to be manufactured independently and then mounted onto the connector assembly, reducing production complexity while maintaining shielding effectiveness.
Solution Approach 2:
The electromagnetic shielding member is integrated with the grounding bar to form a unified grounding and shielding structure. This merging simplifies the overall assembly by combining two functions (grounding and electromagnetic shielding) into a single component, reducing the number of parts and assembly steps.
2Reliability
If electromagnetic shielding members are formed on the insulating body or terminal module by means of secondary molding, then electromagnetic shielding performance is improved, but replacement flexibility is reduced
Solution Approach 1:
The electromagnetic shielding member is designed as a separate, modular component that can be independently removed and replaced. This segmentation enables flexible replacement of the shielding member without affecting the insulating body or terminal module, improving adaptability and versatility.
Solution Approach 2:
The electromagnetic shielding member is designed with dynamic replaceability, allowing it to be easily installed and removed as needed. This dynamic design enables the shielding member to be adapted to different requirements or replaced when degraded, enhancing system flexibility.
3Reliability
If electromagnetic shielding members are formed on the insulating body or terminal module by means of secondary molding, then electromagnetic shielding performance is improved, but manufacturing efficiency is reduced
Solution Approach 1:
The electromagnetic shielding member is manufactured as a separate component using optimized processes, allowing parallel production of the shielding member and the insulating body with terminal module. This segmentation enables concurrent manufacturing, improving overall productivity while maintaining shielding performance.
Solution Approach 2:
The electromagnetic shielding member is pre-assembled with the grounding bar before final assembly with the insulating body and terminal module. This preliminary action simplifies the final assembly process and allows for more efficient manufacturing workflows.
