Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bendable display devices face issues with structural damage, reduced uniform curvature implementation, and display module shaking during mode transitions, particularly due to the limitations of grip and non-grip methods.
Innovation Solution
A bendable display device with a bending system comprising a fixed plate, rotating plate, and horizontal bars, featuring pinion and rack portions, allows for seamless switching between flat and bended modes using a grip or non-grip method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a grip method is used to bend the display module, then the display module can be bent, but the display panel is damaged and uniform curvature is reduced
Solution Approach 1:
The patent introduces a bending system as an intermediary mechanism between the user's bending action and the display module. This system includes a bending hinge connected to a bending bar that contacts the display module, allowing force to be applied through a controlled mechanical pathway rather than direct hand contact, thereby preventing panel damage while enabling bending operation
2Ease of operation
If a grip method is used to bend the display module, then the display module can be bent, but flat surface implementation is reduced
Solution Approach 1:
The bending bar acts as a mediator that distributes bending force uniformly across the display module surface. By contacting multiple points on the module and using the hinge mechanism to control the bending arc, the system maintains flat surface quality while enabling the bending operation
3Reliability
If a non-grip method is used to bend the display module, then the display panel is protected, but the display module shakes during mode switching
Solution Approach 1:
The bending system serves as a stable intermediary mechanism that provides controlled force application. The hinge joint and bending bar work together to maintain structural stability during mode switching, preventing display module shaking while protecting the panel from direct contact forces
Solution Approach 2:
The bending system is pre-configured with the hinge and bending bar in position before bending operation. This preliminary arrangement ensures that the force application pathway is already established and stable, preventing shaking during the actual bending and mode switching process
4Reliability
If a non-grip method is used to bend the display module, then the display panel is protected, but curvature implementation is reduced
Solution Approach 1:
The bending bar, as an intermediary component, transmits and distributes the bending force to achieve uniform curvature. By contacting multiple points on the display module and using the hinge mechanism to control the bending arc, the system achieves high-quality curvature implementation while protecting the panel through controlled force application
