Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If metal wiring is formed on a stretchable substrate, then the display can be flexible and stretchable, but the metal wiring becomes misshapen or damaged when the substrate contracts and stretches
Solution Approach 1:
The display panel is divided into multiple case sections that can move independently. Each case section accommodates movable surfaces that can rotate about a center axis, allowing the structure to segment and adapt during stretching while maintaining overall integrity
Solution Approach 2:
The movable surfaces are designed to rotate dynamically in response to stretching forces. The actuator system enables the movable surfaces to rotate in a predetermined direction, transforming the static structure into a dynamic one that can adapt to deformation without damaging the metal wiring
2Length of moving object
If the display panel is stretched for expansion, then the display size increases, but the structural integrity and image visibility may be compromised
Solution Approach 1:
The actuator system enables the movable surfaces to rotate dynamically during stretching, maintaining structural integrity. The rotation mechanism ensures that components move in a controlled manner that preserves the display's functionality while expanding its size
3Adaptability or versatility
If the movable surfaces rotate to accommodate stretching, then the display can expand, but the device complexity increases due to additional components
Solution Approach 1:
The actuator serves multiple functions: it rotates the movable surfaces, maintains structural integrity during stretching, and enables controlled expansion. This multi-functionality reduces the need for additional separate components, managing device complexity while achieving expandability
