Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel uses a fixed rigid structure, then the manufacturing process is simple, but the display panel cannot deform to fit different shapes
Solution Approach 1:
The display panel is divided into multiple display islands separated by bridging units. The bridging units contain stress relief holes that allow differential deformation between regions, enabling the overall structure to adapt to various shapes while maintaining manufacturing feasibility through modular design
Solution Approach 2:
Stress relief holes are introduced into the bridging units to create a porous structure. These holes allow the bridging units to deform independently from the display islands, enabling shape adaptation without compromising the integrity of the display regions
2Adaptability or versatility
If the display panel is made deformable with stress relief holes, then shape adaptability is improved, but stress concentration may occur at the holes
Solution Approach 1:
The stress relief holes, which could potentially create stress concentration points, are strategically designed to actually reduce overall stress in the bridging units. The holes allow the structure to deform in a controlled manner, converting potential stress concentration into beneficial stress distribution that protects the signal wirings
Solution Approach 2:
The bridging units act as intermediary elements between the display islands. They contain stress relief holes that serve as mediators to manage stress transmission, allowing the display islands to remain stress-free while the bridging units absorb and distribute mechanical stresses
3Reliability
If conventional rigid wiring is used, then electrical connectivity is stable, but the wiring cannot withstand deformation stress
Solution Approach 1:
The signal wirings are constructed using composite materials that combine conductive properties with elastic characteristics. This allows the wirings to maintain stable electrical connectivity while possessing the flexibility and stress resistance needed to withstand deformation during shape changes
4Adaptability or versatility
If the display panel uses a uniform structure, then manufacturing is simple, but it cannot accommodate different substrate shapes
Solution Approach 1:
The display panel employs a segmented architecture with display islands and bridging units. This segmentation allows uniform manufacturing processes for each module while the overall assembled structure achieves versatility in accommodating different substrate shapes
Solution Approach 2:
The bridging units are designed with multi-functionality: they provide structural support, contain stress relief holes for deformation accommodation, and serve as pathways for signal wirings. This universal design enables a single component type to fulfill multiple roles across different application scenarios
