Elastic Variable Holder for Flexible Electrode Elongation Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible electrode materials, such as those used in flexible displays, suffer from deteriorated performance due to repeated deformation, which affects their electric characteristics and is not accurately represented in existing elongation tests that cause unnecessary distortion.
Innovation Solution
An elongation tester with a variable holder made of elastic material that deforms in the longitudinal direction of the tested material, minimizing shape distortion while allowing for realistic simulation of the material being fixed by a frame, and a driver for controlled reciprocation to measure resistance changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rigid holder is used to hold the tested material during elongation testing, then the holder provides stable support and easy operation, but it causes unnecessary shape distortion of the flexible electrode material
Solution Approach 1:
The holder is changed from a rigid structure to an elastic structure, fundamentally changing the mechanical parameter of stiffness. This allows the holder to deform elastically during testing, accommodating the flexible electrode material without causing permanent shape distortion, while still providing stable support and easy operation.
2Shape
If the holder is made flexible to avoid shape distortion, then the material shape is preserved, but the holder structure becomes more complex
Solution Approach 1:
The holder is designed as an elastic component that can deform flexibly during testing. This flexible structure naturally adapts to the shape changes of the flexible electrode material without requiring complex mechanisms, achieving shape preservation through material elasticity rather than complex structural design.
3Productivity
If existing elongation testing methods are used on flexible electrodes, then the testing process is simple, but the electric characteristic measurements are inaccurate due to shape distortion
Solution Approach 1:
The testing method is enhanced by integrating electrical measurement capabilities with the mechanical elongation testing system. The resistance measuring unit is incorporated into the holder structure, allowing simultaneous mechanical deformation and electrical property measurement without requiring separate testing equipment, thus maintaining high productivity while achieving accurate electric characteristic measurements.
