Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display devices face issues with deformation and damage at the folding area due to unforeseen tensile forces during folding operations.
Innovation Solution
The display device incorporates a supportive structure with spacers, sliding parts, and elastic components that guide the movement of supporters to reduce tensile forces at the folding area, utilizing spacers and elastic parts to maintain the display module's position and prevent deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device is made foldable to improve portability and convenience, then the ease of operation is improved, but the folding area is subjected to tensile forces causing deformation and damage
Solution Approach 1:
Elastic parts are disposed in guide grooves of the third and fourth supporters to provide beforehand cushioning. When the display device is folded, these elastic parts elastically deform to absorb tensile forces generated at the folding area, preventing deformation and damage before they can occur. This prior cushioning mechanism ensures the folding area maintains its integrity while enabling foldable operation.
Solution Approach 2:
The elastic parts act as intermediary elements between the third and fourth supporters at the folding area. Instead of directly connecting the supporters rigidly, the elastic parts mediate the interaction by deformably transmitting forces, thereby reducing tensile stress on the folding area while maintaining structural connection and enabling portable folding operation.
2Manufacturing precision
If rigid support structures are used to maintain display module position, then manufacturing precision is improved, but tensile forces at the folding area increase causing deformation
Solution Approach 1:
The support structure transitions from a completely rigid configuration to one with elastic components. The elastic parts change the mechanical parameters of the support system by introducing controlled flexibility, allowing the structure to maintain positioning precision while adapting to folding movements and reducing tensile forces that cause deformation.
Solution Approach 2:
The support structure incorporates dynamic elements through the elastic parts that can deform and recover. This dynamic characteristic allows the third and fourth supporters to move relative to each other during folding while maintaining display module positioning, converting a static rigid structure into a dynamic adaptive system that prevents folding area deformation.
