Flexible Bottom Shell Hinged Plates Prevent Display Folds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices in prior art suffer from serious folds when bending, leading to poor display quality due to lack of a supportive bendable structure.
Innovation Solution
A flexible bottom shell design featuring connection plates that are successively bonded and hinged together, with hinge pieces and sliding chutes to distribute stress uniformly, preventing folds and ensuring seamless bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexible display devices bend without a supportive bendable structure, then the device can achieve flexibility and arc shape, but serious folds appear at the bendable position causing poor display quality
Solution Approach 1:
The bottom shell is divided into multiple connection plates that are hinged together, allowing each plate to independently manage stress during bending. This segmentation prevents concentrated stress at single points that would cause folds, while maintaining overall flexibility of the structure.
Solution Approach 2:
The patent employs a flexible bottom shell structure composed of multiple hinged plates that can bend without rigid resistance. This flexible shell design allows the display device to achieve arc shapes while the hinged structure distributes bending stress uniformly, preventing fold formation on the display surface.
2Strength
If a rigid bottom shell structure is used, then structural strength is maintained, but the device cannot bend and achieve flexible display functionality
Solution Approach 1:
The bottom shell transitions from a static rigid structure to a dynamic hinged structure. The connection plates can rotate relative to each other at hinge points, enabling the shell to adapt its shape during bending while maintaining structural integrity through the connected plates.
Solution Approach 2:
The patent combines rigid connection plates with flexible hinged joints to create a hybrid structure. Each connection plate maintains rigidity for structural strength, while the hinged joints between plates provide flexibility, achieving both strength and bendability in the bottom shell.
3Manufacturing precision
If uniform stress distribution is achieved through hinged connection plates, then folds are prevented and display quality is maintained, but the structure becomes more complex
Solution Approach 1:
By segmenting the bottom shell into multiple hinged connection plates, the structure distributes bending stress across multiple joints rather than concentrating it. This segmentation prevents folds on the display surface while the modular plate design keeps the overall structure manageable and systematic.
