Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing silicon flexible connectors lack the necessary flexibility in both the y- and z-directions, which can lead to shearing and failure when connecting electronic components with varying orientations.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single uniform flexible sheet is used for the connector section, then ease of manufacture is improved, but flexibility in multiple directions deteriorates
Solution Approach 1:
The connector section is segmented into multiple thin narrow flexible strands separated by slots, transforming a single uniform flexible sheet into a structured array of flexible elements. This segmentation enables the connector to flex in both y- and z-directions while maintaining ease of manufacture through the single-piece construction approach.
2Adaptability or versatility
If the connector section is made thin to increase flexibility, then flexibility is improved, but mechanical strength deteriorates
Solution Approach 1:
Metal traces are locally deposited within the flexible strands to provide electrical conductivity and reinforce mechanical strength. The metal traces are strategically placed in the flexible strands where needed, providing localized strengthening without compromising the overall flexibility of the thin connector section.
3Adaptability or versatility
If slots are formed to create flexible strands, then flexibility in multiple directions is improved, but device complexity deteriorates
Solution Approach 1:
The slots are formed through a single etching process that simultaneously creates multiple separated flexible strands within the connector section. This merging of operations allows the complex multi-strand structure to be manufactured as a single integrated piece, reducing assembly complexity while achieving the desired flexibility.
