Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a support rack with specific curve is mounted to force the backplane to deform, then the backplane achieves a curved shape, but the curvature is fixed and cannot be adjusted
Solution Approach 1:
The patent applies the dynamics principle by replacing the fixed support rack with a dynamic curvature adjustment mechanism. The backplane is equipped with multiple support points that can independently adjust their positions, allowing the curvature to be dynamically changed according to user needs. This transforms the static curved structure into a flexible, adjustable system that can adapt to different viewing preferences.
Solution Approach 2:
The patent implements parameter changes by enabling continuous adjustment of curvature parameters. Instead of being constrained to a single fixed curve, the system allows modification of curvature radius and support point positions, providing users with the ability to change display parameters to suit different viewing conditions and preferences.
2Shape
If a support rack with specific curve is mounted to force the backplane to deform, then the backplane achieves a curved shape, but the structure becomes complicated and cost increases
Solution Approach 1:
The patent applies segmentation by dividing the backplane support system into multiple independent support points or modules. Each support point can be individually adjusted, replacing the need for a complex integrated support rack. This modular approach simplifies the overall structure while enabling flexible curvature adjustment through coordinated movement of discrete elements.
Solution Approach 2:
The patent replaces the complex mechanical support rack system with a simpler mechanism, potentially using actuators or adjustable feet at discrete support points. This substitution reduces structural complexity by eliminating the need for a rigid, pre-formed curved rack while achieving the same backplane deformation through controlled local adjustments.
3Shape
If a support rack with specific curve is mounted to force the backplane to deform, then the backplane achieves a curved shape, but the view angle is subjected to undesired constraint
Solution Approach 1:
The patent applies dynamics by enabling real-time adjustment of the backplane curvature to optimize viewing angles for different user positions. Instead of being constrained to a fixed curve, the system can dynamically modify the curvature profile to accommodate varying viewing conditions, thereby improving ease of operation and user comfort.
Solution Approach 2:
The patent implements parameter changes by allowing adjustment of curvature parameters to optimize viewing experience. Users can modify the curvature radius and support point configurations to achieve optimal viewing angles for different seating positions, transforming the constrained fixed-angle system into a flexible, user-adaptable display.

AI summary
The present invention provides a curvature adjustment structure of a curved liquid crystal display device, which includes: a backplane (1) and at least one bracing assembly (3) fixedly mounted to the backplane (1). Each bracing assembly (3) includes a first bracing member (31) in contact engagement with the backplane (1), a second bracing member (33) opposite to the first bracing member (31) and distant from the backplane (1), and a cooling chip array (35) arranged between the first and second bracing members (31, 33). The cooling chip array (35) includes a plurality of cooling chips (2). Each of the cooling chips (2) includes a heat absorption surface (22) and an opposite heat dissipation surface (24). The heat absorption surface (22) and the heat dissipation surface (24) of each of the cooling chips (2) are respectively in engagement with the first and second bracing members (31, 33), whereby through energizing the cooling chip array (35), the first and second bracing members (31, 33) are respectively caused to undergo thermal expansion and contraction to achieve curving and deformation of the bracing assembly (3) so as to forcibly change the curvature of the backplane (1).
