Rigid-Soft Edge Protection for Foldable Display Bending Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display terminals have exposed edges at the bending region relative to the stationary shaft, which can be damaged during use and affect the appearance, reducing reliability.
Innovation Solution
An edge protection structure combining a rigid member and a soft rubber member, where the rigid member is connected to the soft rubber member via a connector, covers the edge of the bending region to prevent exposure and damage, while allowing flexible bending without affecting the display's functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display is folded relative to the stationary shaft, then the foldable display terminal achieves compact form factor, but the edge of the display is exposed and vulnerable to damage
Solution Approach 1:
The edge protection structure is nested within the foldable display terminal, with the protection component positioned inside the housing and wrapping around the display edge. The structure utilizes the existing space within the terminal body to accommodate the protective element without increasing overall volume, achieving both compact form factor and edge protection.
Solution Approach 2:
The edge protection structure is pre-installed on the display before folding occurs. The protection component is positioned in advance to wrap around the display edge, ensuring that when the display is folded or subjected to collision, the protective coverage is already in place to prevent damage.
2Strength
If a rigid structure is used to protect the display edge, then collision resistance is improved, but the structure cannot accommodate flexible bending of the display
Solution Approach 1:
The edge protection structure combines rigid and soft components in a composite configuration. The rigid component provides collision resistance and structural strength, while the soft component offers flexibility and cushioning to accommodate bending movements. This composite approach allows the protection structure to maintain both strength and adaptability simultaneously.
Solution Approach 2:
Different portions of the edge protection structure have different mechanical properties. The rigid component is positioned to provide structural support and collision resistance, while the soft component is positioned to accommodate bending and provide flexible protection. This local differentiation of material properties allows the structure to optimize both strength and flexibility in their respective locations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The edge protection structure effectively prevents damage to the display's edges during collisions and maintains the appearance quality of the foldable display terminal by integrating rigid and soft components that work synergistically to protect and support the bending region.
Implementation Method 1
The soft rubber member includes a protection part... the protection part is configured to cover the edge of the bending region
