Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light-emitting chips are connected using straight conductive lines, then electrical connection is simple, but the array lacks flexibility and cannot be stretched
Solution Approach 1:
The conductive line is divided into multiple segments with different curvature radii. The first segment has a first curvature radius and the second segment has a second curvature radius different from the first. This segmentation allows the conductive line to be stretched while maintaining electrical connection between light-emitting chips.
Solution Approach 2:
The conductive line incorporates curved segments with different curvature radii instead of straight lines. The first segment has a first curvature radius and the second segment has a second curvature radius, enabling the structure to accommodate stretching and deformation while maintaining connectivity.
2Illumination intensity
If light-emitting chips are spaced closer together, then the array structure is compact, but luminance and durability are reduced
Solution Approach 1:
The conductive line structure is designed to be dynamically adjustable in terms of the distance it spans between chips. By using segments with different curvature radii, the effective distance between chips can be increased while the conductive line maintains its connecting function, allowing for optimized luminance and durability.
3Reliability
If the conductive line is made rigid to ensure stable electrical contact, then connection reliability is high, but the array cannot be stretched or deformed
Solution Approach 1:
The conductive line is segmented into portions with different curvature radii, allowing each segment to maintain electrical connectivity while accommodating deformation. The first segment with its specific curvature radius and the second segment with a different curvature radius work together to provide both stability and flexibility.
Solution Approach 2:
The curvature radius parameter of the conductive line is varied across different segments. The first segment has a first curvature radius and the second segment has a second curvature radius, allowing the structure to change its geometric parameters to accommodate stretching while maintaining electrical contact.
