Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an insulating housing is used in the electrical connector, then the manufacturing simplicity is maintained, but the shielding effect and signal transmission quality deteriorate
Solution Approach 1:
The housing is constructed as a composite structure combining insulating material and conductive material. The insulating housing body provides electrical insulation, while the conductive sheet integrated into the housing provides shielding functionality. This composite approach resolves the contradiction by incorporating both insulating and shielding properties within a single integrated housing structure.
2Device complexity
If no ground sheet is added to the electrical connector, then the device complexity is reduced, but the static electricity discharge capability deteriorates
Solution Approach 1:
The conductive sheet serves multiple functions simultaneously: it provides shielding against electromagnetic interference, establishes a reference potential for signal transmission, and enables static electricity discharge through its connection to the grounding terminal. This multi-functionality resolves the contradiction by achieving enhanced reliability without proportionally increasing device complexity.
3Device complexity
If the conductive terminal contacts the conductive housing directly, then the grounding path is simplified, but the signal integrity deteriorates due to interference
Solution Approach 1:
The grounding path is segmented into distinct zones: the conductive terminal contacts the conductive sheet at a specific grounding point rather than directly with the conductive housing. This segmentation creates a controlled grounding interface that separates the signal transmission path from the shielding/grounding path, reducing electromagnetic interference while maintaining effective grounding.
