Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the connector structure is miniaturized to meet lightweight and slim device requirements, then the device size and weight are reduced, but the distance between terminals is shortened resulting in degraded shielding effect
Solution Approach 1:
The grounding structure is segmented into multiple grounding terminals (first grounding terminals on the top surface and second grounding terminals on the bottom surface) distributed at outmost positions of both sides of the terminal assemblies. This segmentation allows the grounding function to be distributed across multiple points, enhancing the overall shielding effect even when the connector size is reduced.
Solution Approach 2:
The grounding terminals are strategically positioned at the outmost positions of both sides of the terminal assemblies, creating localized high-density grounding zones at critical interference points. This local quality enhancement ensures effective shielding at the most vulnerable areas where electromagnetic interference is most likely to occur, maintaining protection effectiveness despite overall miniaturization.
2Object-affected harmful factors
If a ground piece is provided to separate two sets of terminals, then signal interference between terminals is prevented, but the connector structure becomes more complex and assembly difficulty increases
Solution Approach 1:
The grounding function is merged with the terminal assembly structure itself. The grounding terminals are integrated as part of the terminal assemblies, with the first grounding terminals forming part of the first terminal assembly and the second grounding terminals forming part of the second terminal assembly. This merging eliminates the need for a separate ground piece, simplifying the overall structure while maintaining effective signal separation and interference prevention.
Solution Approach 2:
The terminal assemblies serve multiple functions: they provide both signal transmission terminals and grounding terminals. The first terminal assembly contains both signal terminals and first grounding terminals, while the second terminal assembly contains both signal terminals and second grounding terminals. This multi-functionality reduces the number of separate components needed, simplifying the connector structure while maintaining effective shielding.
