Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid structure is used for the display panel, then structural stability is improved, but flexibility and curvature change capability deteriorate
Solution Approach 1:
The patent applies the dynamics principle by implementing a movable support structure with adjustable support points. The support module includes a movable support plate and adjustable support legs that can dynamically reposition to accommodate different curvature states of the flexible display panel, enabling the panel to transition between flat and curved configurations while maintaining structural stability in each state
Solution Approach 2:
The patent applies parameter changes by modifying the physical state and mechanical properties of the display panel through controlled deformation. The support module adjusts support parameters (position, force, distribution) to enable the panel to achieve different curvature radii and angles, transforming the panel from a rigid-flat state to a flexible-curved state with controlled geometric parameters
2Adaptability or versatility
If the display panel is made flexible to enable curvature change, then adaptability is improved, but structural rigidity and stability deteriorate
Solution Approach 1:
The patent applies segmentation by dividing the support structure into multiple independent support legs and adjustable support points distributed across the panel背面. This segmented support system provides localized reinforcement without constraining the overall flexibility of the display panel, allowing different regions to be supported independently to maintain rigidity where needed while preserving flexibility for curvature changes
3Manufacturing precision
If a fixed curvature structure is used, then manufacturing precision is improved, but adaptability to different applications deteriorates
Solution Approach 1:
The patent applies universality by designing a multi-functional support module that can serve multiple purposes: providing structural support, enabling curvature adjustment, and adapting to different display panel sizes and configurations. The adjustable support legs and movable support plate create a universal system that maintains manufacturing precision for consistent curvature while adapting to various application requirements through parameter adjustment
