Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a curved display apparatus is manufactured with a predetermined curvature using a flexible display panel fixed in a curved case, then the display panel maintains a stable curved shape, but it becomes difficult to change the radius of curvature or shape of the display panel
Solution Approach 1:
The patent applies the dynamics principle by transforming the static curved case into a dynamic structure capable of shape transformation. The variable case includes a first curved surface receiving portion and a second curved surface receiving portion that can relatively move with respect to each other, enabling the display panel to transition between different curved shapes. The driving unit actuates these portions to change the radius of curvature dynamically, resolving the contradiction between shape stability and shape changeability.
2Ease of manufacture
If the display panel is bent into a single curved surface, then the structure is simple and easy to manufacture, but various visual effects and concentration of attention are reduced
Solution Approach 1:
The patent enables the display panel to dynamically transition between a simple single curved surface configuration and more complex multi-curved surface configurations. When the first and second curved surface receiving portions are positioned in a specific relationship, the panel forms a single curved surface that is easy to manufacture. When they are positioned differently, multiple curved surfaces are created to provide various visual effects, thus resolving the contradiction between manufacturing simplicity and visual effect variety.
3Adaptability or versatility
If the radius of curvature of the display panel is changed, then consumer requirements for shape variation are met, but the manufacturing process becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the curved case into multiple independent portions: a first curved surface receiving portion and a second curved surface receiving portion. Each portion can be independently positioned and adjusted by the driving unit, allowing the radius of curvature to be changed without requiring complete remanufacturing of the entire case. This modular approach reduces manufacturing complexity while maintaining radius of curvature adjustability.
