Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an anisotropic conductive sheet is used to connect electronic members, then electrical connection is achieved, but connection reliability deteriorates when electronic members are deformed
Solution Approach 1:
The patent employs a double-layer elastic body structure that provides dynamic deformation capability. The first elastic body deforms in the first direction and the second elastic body deforms in the second direction, allowing the connector to adapt to dimensional changes and deformations of electronic members while maintaining reliable electrical connection through the anisotropic conductive sheet.
2Volume of moving object
If the size of electronic parts is reduced, then miniaturization is achieved, but cushioning capability deteriorates
Solution Approach 1:
The patent introduces a specialized cushioning member with specific local properties between the pressing member and the anisotropic conductive sheet. This cushioning member has a pressing surface area larger than the anisotropic conductive sheet, distributing pressure locally to provide sufficient cushioning capability while maintaining overall compact dimensions of the electronic parts.
Solution Approach 2:
The patent uses a composite structure combining multiple materials with different properties: the elastic body provides flexibility, the cushioning member provides pressure distribution, and the anisotropic conductive sheet provides electrical connection. This composite approach enables miniaturization while preserving adequate cushioning capability through optimized material combinations.
3Reliability
If a pressing member is added to maintain connection, then connection stability is improved, but device complexity increases
Solution Approach 1:
The patent integrates the pressing function directly into the connector assembly by combining the pressing member, elastic bodies, and anisotropic conductive sheet into a unified structure. The pressing member is positioned to press the second elastic body, which in turn presses the anisotropic conductive sheet between the first and second electronic members, creating a consolidated connection mechanism that maintains stability without excessive complexity.
4Adaptability or versatility
If an elastic body is disposed on the second electronic member, then deformation compensation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent divides the elastic deformation function into two separate components: the first elastic body that deforms in the first direction and the second elastic body that deforms in the second direction. This segmentation allows each elastic body to be optimized for specific deformation directions, improving overall deformation compensation while reducing the complexity of manufacturing and assembly precision requirements compared to a single multi-directional elastic component.
