Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If multiple conducting portions are added to reduce electromagnetic noise, then noise reduction capability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple conducting portions (first conducting portion connected to shield member, second conducting portion connected to enclosure, third conducting portion connected to circuit board) into a single integrated connector structure. This merging approach achieves noise reduction through multiple grounded paths while avoiding the complexity of separate independent components, as all conducting portions are structurally integrated into one connector assembly
Solution Approach 2:
The connector structure serves multiple functions simultaneously: it provides signal transmission through contacts, electromagnetic shielding through the first conducting portion connected to the shield member, and grounding through the second and third conducting portions. This multi-functionality allows a single device to address both communication and noise reduction requirements without increasing overall system complexity
2Reliability
If conducting portions are added to form multiple grounded electric current paths, then communication characteristics are improved, but manufacturing complexity increases
Solution Approach 1:
The patent integrates multiple conducting portions into a single molded body structure, where the first, second, and third conducting portions are formed as integrated components within one housing. This merging simplifies manufacturing by reducing the number of separate assembly steps and components, while still achieving multiple grounded electric current paths for improved communication characteristics
Solution Approach 2:
The conducting portions are nested within the housing structure, with the first conducting portion positioned inside the housing and the second and third conducting portions integrated into the housing walls. This nesting arrangement allows multiple functional elements to be contained within a single manufactured component, simplifying the overall manufacturing process
