Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a metallic housing is used as an isolation wall to ground inner noises, then EMI cross talks are reduced, but the manufacturing process becomes complex and assembly difficulty increases
Solution Approach 1:
The patent combines the shielding housing and shielding member into an integrated structure where the shielding member is formed as an integral part of the housing body. This merging eliminates the need for separate assembly steps while maintaining the EMI shielding function, thus reducing manufacturing complexity while still grounding inner noises effectively.
Solution Approach 2:
The shielding structure is segmented into different functional zones: the housing provides outer shielding, while the integrated shielding member provides inner shielding. This segmentation allows each part to optimize its shielding function independently while simplifying the overall manufacturing process through integral formation.
2Object-affected harmful factors
If multiple separate parts are used for shielding, then EMI isolation is improved, but manufacturing precision requirements increase
Solution Approach 1:
By merging the shielding member with the housing into an integral structure, the patent eliminates multiple assembly interfaces that would require high manufacturing precision. The integrated design ensures consistent positioning and electrical connection without requiring tight tolerances between separate parts.
3Reliability
If a complex release mechanism is used, then connector reliability is improved, but productivity decreases
Solution Approach 1:
The release mechanism is integrated into the housing structure rather than being a separate assembly. This merging reduces the number of parts and assembly steps required, thereby improving productivity while maintaining the reliability function through the integrated design.
