Solution Overview
Problem
Foldable display devices often experience deformation and damage at the folding portion due to unforeseen issues, necessitating the development of technology to prevent such problems.
Innovation Solution
A foldable display device design featuring a flexible display module supported by multiple supporters with spacers, sliding parts, elastic parts, and hinge parts, which reduce tensile force in the folding area by allowing supporters to move towards the center when folded, thereby preventing deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a foldable display device is folded about a folding axis, then the device becomes portable and flexible, but the folding portion experiences deformation and damage due to tensile force
Solution Approach 1:
The patent implements a dynamic support system where the support member can move relative to the housing along the folding axis. When the device is folded, the support member moves to follow the curvature of the fold, dynamically adapting its position to maintain proper spacing and prevent deformation of the display module at the folding area.
Solution Approach 2:
The support member acts as an intermediary element between the housing and the display module. It mediates the mechanical stress during folding by moving independently, thereby protecting the display module from direct tensile force and preventing deformation at the folding area.
2Stability of the object's composition
If the display module is rigidly supported, then structural stability is maintained, but tensile force causes deformation at the folding area during folding
Solution Approach 1:
The support member transitions from a static to a dynamic element, capable of moving along the folding axis. This dynamic capability allows the system to maintain structural stability in the unfolded state while adapting to shape changes during folding, preventing deformation at the critical folding area.
Solution Approach 2:
The support system is segmented into movable and fixed components. The support member is separated from the housing, allowing independent movement. This segmentation enables the support member to follow the folding curvature while the housing maintains its overall structural stability.
3Reliability
If multiple supporters are added to support the display module, then deformation is prevented, but device complexity increases
Solution Approach 1:
The single movable support member performs multiple functions: it maintains spacing between the display module and housing, follows the folding curvature, and protects the display module from tensile force. This multi-functional design achieves reliable folding area protection without the complexity of multiple separate support structures.
Solution Approach 2:
The patent merges the support and spacing functions into a single integrated support member that moves along the folding axis. This consolidation achieves the protective effect of multiple supporters while reducing structural complexity compared to having separate support elements.
