Foldable Display Screen Meander Line Gap Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display screens have low reliability due to right-angle vertices at the intersections of the meander line and edge line, which concentrate force and increase fragility when subjected to external forces.
Innovation Solution
Incorporating gaps at the ends of the meander line, such as V-shaped or r-shaped gaps, to transform right-angle vertices into obtuse angles or arcs, thereby distributing force more evenly and enhancing the bearing capacity of the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the meander line intersects the edge line at right angles to form a compact foldable display screen structure, then the screen structure is simplified and easier to manufacture, but the reliability decreases due to stress concentration at the right-angle vertices
Solution Approach 1:
The patent transforms the right-angle vertices into arc-shaped structures by introducing curved transition segments between the meander line and edge line. This curvature eliminates the sharp corners that concentrate stress, distributing the load more evenly across the folded structure while maintaining the compact form factor and manufacturing simplicity of the original design.
2Device complexity
If right-angle vertices are formed at the intersections of meander line and edge line, then the bearing capacity to external force is reduced, but the structural design is simpler
Solution Approach 1:
The arc-shaped transition segments replace the right-angle vertices, creating a curved path that distributes external forces along the arc rather than concentrating them at a single point. This increases the bearing capacity while adding minimal complexity to the overall structural design.
Solution Approach 2:
The patent changes the geometric parameters at the critical intersection points by introducing arc-shaped transitions with specific radii and curvature profiles. This parameter modification optimizes the stress distribution and enhances the bearing capacity without fundamentally altering the meander line folding structure.
