Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If each component is designed and manufactured separately with predetermined curvature, then the curvature precision of each component is improved, but the manufacturing cost and device complexity increase significantly
Solution Approach 1:
The backplane is designed with universal flexibility to adapt to different curvature requirements. Instead of creating specialized curved components for each curvature value, the backplane can be bent to match various curvatures, making it a multi-functional base that supports diverse display device configurations without requiring separate molds for each component.
Solution Approach 2:
The backplane transitions from a rigid, fixed-curvature component to a dynamic, flexible structure that can be bent and shaped. This dynamic property allows the backplane to adapt its curvature to match different display modules and front frames, eliminating the need for multiple predetermined curvature molds and reducing manufacturing complexity.
2Manufacturing precision
If multiple molds of predetermined curvatures are established for different components, then the curvature accuracy is improved, but the manufacturing cost increases
Solution Approach 1:
A single backplane design serves multiple curvature requirements. Instead of investing in multiple expensive molds for different curvatures, the universal backplane can be manufactured once and then bent to various curvatures as needed, significantly reducing tooling costs while maintaining the ability to produce accurate curved displays.
Solution Approach 2:
The curvature parameter of the backplane is changed after manufacturing rather than during molding. By creating a flat backplane first and then bending it to the required curvature, the system avoids the high cost of creating multiple molds with different curvature parameters, achieving cost-effective production of various curved display configurations.
3Stability of the object's composition
If components are manufactured with fixed curvatures, then the structural stability is improved, but the adaptability to different curvatures deteriorates
Solution Approach 1:
The backplane is designed with dynamic flexibility rather than fixed rigidity. This allows the structure to maintain stability during assembly and operation while adapting its curvature to match different display modules and front frames. The flexible backplane can be bent to various curvatures and then maintained in that shape, providing both adaptability and structural integrity.
Solution Approach 2:
The backplane utilizes a flexible shell structure that can be bent and shaped to different curvatures. This flexible design allows the backplane to adapt to various curvature requirements while maintaining sufficient structural stability to support the display module and front frame, eliminating the need for rigid, pre-formed curved components.

AI summary
The present invention provides a display panel, including a backplane having flexibility, a first fixing member, a front frame having flexibility, and a display module provided between the backplane and the front frame. The backplane has a base plate with a first side. The first fixing member extends corresponding to the first side and has a first predetermined curvature. The first fixing member at least has a first wall body standing upright relative to the base plate, and the first fixing member is relatively fixed to the backplane, so that the curvature of the backplane can be adjusted corresponding to the first fixing member. The front frame is provided in a manner that extends correspondingly to the periphery of the backplane, and is relatively fixed to the backplane, so that the curvature of the front frame is relatively adapted to that of the backplane.
