Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pixels are disposed only on the front surface of the display panel, then the manufacturing process is simple, but the display device cannot display images on side surfaces
Solution Approach 1:
The display panel extends from a traditional two-dimensional front surface to a three-dimensional structure that includes side surfaces. The first and second extension surfaces protrude from the front and rear surfaces respectively, creating additional display areas on the sides of the display device, thus utilizing spatial dimensions beyond the conventional planar display.
Solution Approach 2:
The display panel is divided into multiple distinct surfaces: a front surface, a rear surface, and four side surfaces (first and second extension surfaces, and first and second side surfaces). Each surface can independently display images, allowing the display device to show different content on different faces, effectively segmenting the display function across multiple spatial locations.
2Area of stationary object
If the extension surfaces are made long to increase display area, then more content can be displayed, but stress and bending difficulty increase
Solution Approach 1:
The first and second extension surfaces have different lengths adapted to their specific functions. The first extension surface has a longer first side to provide sufficient display area on the side, while the third side is shortened to reduce stress concentration at the corner. The second extension surface similarly adjusts its side lengths to balance display area and structural integrity, with each surface having optimized local dimensions rather than uniform proportions.
Solution Approach 2:
The extension surfaces are designed with asymmetric dimensions where adjacent sides have different lengths. Specifically, the first side of the first extension surface is longer than its third side, and similarly for the second extension surface. This asymmetric design allows the display area to be maximized in critical directions while reducing material and stress in less critical areas, improving overall flexibility.
3Area of stationary object
If the third side of extension surfaces is made long, then display area increases, but stress at contact points increases making bending difficult
Solution Approach 1:
The third sides of the first and second extension surfaces are specifically shortened to reduce stress concentration at the contact points where these surfaces meet the first and second side surfaces. This local modification maintains sufficient display area on the primary sides while eliminating excessive material that would create harmful stress concentrations during bending operations.
4Stability of the object's composition
If a rigid structure is used to maintain panel stability, then structural integrity is improved, but flexibility and bending capability are reduced
Solution Approach 1:
The display panel utilizes a flexible substrate structure that allows the entire panel including extension surfaces to be bent without damage. This flexible construction enables the display device to adapt to different mounting configurations and spatial arrangements while maintaining structural integrity, transforming the panel from a rigid component to a flexible one that can conform to various geometric requirements.
