Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If small grounding members are used to eliminate noise, then noise elimination effectiveness is improved, but assembly difficulty increases
Solution Approach 1:
The patent combines multiple grounding members into a single integrated grounding structure that includes a grounding plate and multiple grounding arms. This merging approach maintains the noise elimination effectiveness of multiple grounding points while significantly improving assembly ease, as the entire grounding system can be installed as one unit rather than assembling multiple separate small grounding members.
Solution Approach 2:
The grounding structure is segmented into functional components (grounding plate, grounding arms, contact elements) that are pre-assembled together. This segmentation allows the grounding system to maintain the benefits of multiple contact points while being manufactured and installed as a unified module, resolving the assembly difficulty issue.
2Object-affected harmful factors
If multiple grounding members are used to increase grounding area, then electromagnetic interference protection is improved, but device complexity increases
Solution Approach 1:
Multiple grounding functions are merged into a single integrated grounding structure that provides extensive grounding area through its grounding plate and multiple grounding arms. This consolidation maintains EMI protection effectiveness while reducing device complexity by eliminating the need for multiple separate grounding components and their associated mounting structures.
Solution Approach 2:
The grounding structure serves multiple functions simultaneously: it provides EMI shielding, establishes electrical ground connections, and offers mechanical support. This multi-functionality reduces the need for separate components, thereby decreasing device complexity while maintaining comprehensive EMI protection.
