360-Degree Folding Jig for Flexible Display Durability Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional durability test jigs are inadequate for testing flexible display panels that can be folded or rolled, as they lack the capability to perform in-folding, out-folding, and 360-degree folding actions effectively.
Innovation Solution
A 360-degree folding jig is designed with a fixed plate module, a folding plate module, and rotation support modules that allow for reciprocal and rotational movements, incorporating elastic members and gear couplings to simulate the folding actions of flexible display panels, ensuring stress-free conditions during testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional durability test jigs are used, then the testing setup is simple, but they cannot perform in-folding, out-folding, and 360-degree folding actions effectively
Solution Approach 1:
The jig is divided into multiple independent modules: a fixed plate module, a folding plate module, and a pair of rotation support modules. Each module performs a specific function (supporting one side of the sample, enabling rotational movement, providing reciprocal motion), allowing the system to achieve complex 360-degree folding capabilities through the coordination of simpler, specialized components rather than requiring a monolithic complex structure
Solution Approach 2:
The folding plate module is designed to be reciprocally movable relative to the fixed plate module, enabling dynamic in-folding and out-folding actions. The rotation support modules allow the folding plate module to rotate 360 degrees, transforming the static conventional jig into a dynamic system that can perform multiple folding sequences (in-folding, out-folding, 360-degree folding) to comprehensively test flexible display panel durability
2Adaptability or versatility
If the folding plate module is made reciprocally movable to enable in-folding and out-folding actions, then the versatility of the jig is improved, but the mechanism complexity increases
Solution Approach 1:
The rotation support modules combine multiple functions into a single component: they support the folding plate module, enable reciprocal motion for in-folding/out-folding actions, and provide rotational capability for 360-degree folding. By merging these functions into integrated rotation support modules with shafts and coupling mechanisms, the design reduces the number of separate components needed compared to using distinct mechanisms for each function
3Ease of manufacture
If the jig structure is simplified, then the ease of manufacture is improved, but the ability to perform stress-free testing is reduced
Solution Approach 1:
The jig applies different structural characteristics to different locations: the fixed plate module provides rigid stable support for one side of the sample, while the folding plate module and rotation support modules provide controlled movable support for the other side. This local differentiation of structural quality allows the system to maintain manufacturing simplicity through modular standard components while achieving stress-free testing through the specialized movable support configuration that accurately replicates real product folding conditions

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 jig enables clear performance of in-folding, out-folding, and 360-degree folding actions, facilitating stress-free testing by stabilizing the reciprocating motion and minimizing stress on the sample, thus providing accurate durability assessments for flexible display panels.
Implementation Method 1
an elastic member for elastically decompressing the reciprocating slider to a front of the moving direction on the basis of the guide panel, while elastically decompressing the reciprocating slider to a rear of the moving direction on the basis of the guide panel
Implementation Method 2
the rotation support module may rotate on the basis of the fixed plate module in connection with a rotation of the folding plate module based on the rotation support module when the folding plate module is in-folded or out-folded on the basis of the fixed plate module
Implementation Method 3
a fixed gear shaft rotatably coupling the fixed support member to the mounting bracket to perform the second shaft; a folding gear shaft rotatably coupling the folding support member to the mounting bracket to perform the first shaft

AI summary
A 360 degree folding jig performs actions similar to those of a product to which a sample is applied when conducting a durability test for the sample. The 360 degree folding jig includes a fixed plate module on which one side of a sample is supported, a folding plate module that is spaced apart from the fixed plate module and on which the other side of the sample is supported so as to be reciprocally movable, and a pair of rotation support modules respectively provided at each end of the mutually adjacent fixed plate module and the folding plate module, and configured to couple the folding plate module to the fixed plate module so that the folding plate module is in-folded or out-folded.
