Folding Test Device with Universal Rotary Frame Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding test devices for foldable display devices require separate equipment for in-folding and out-folding tests, leading to increased costs and testing time.
Innovation Solution
A folding test device with a jig system comprising separate rotary plates and frames that can perform both in-folding and out-folding tests by adjusting the angles and distances between the frames and rotary plates, allowing for independent rotation based on the test object's radius of curvature, and utilizing a rotary driver with a linear motion member and crank mechanism to facilitate folding and unfolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate in-folding test device and out-folding test device are used, then testing accuracy for each folding type is improved, but device complexity and testing cost increase
Solution Approach 1:
The test device is designed with a universal testing platform that can perform both in-folding and out-folding tests using the same core structure. The first and second frames can be configured in different orientations, and the rotary drivers can rotate in different directions, enabling a single device to replace multiple specialized devices while maintaining testing accuracy for each folding type.
2Reliability
If separate in-folding test device and out-folding test device are used, then specialized testing capability for each folding type is improved, but testing time increases
Solution Approach 1:
The device employs dynamic reconfiguration capabilities where the first and second frames can be positioned in different orientations and the rotary drivers can operate in different rotation directions. This dynamic adaptability allows the same hardware to be quickly reconfigured between in-folding and out-folding test modes, eliminating the time required to switch between separate dedicated devices while preserving specialized testing capabilities for each folding type.
3Reliability
If multiple test setups are used for in-folding and out-folding tests, then comprehensive testing coverage is improved, but cost increases
Solution Approach 1:
The test device implements a universal testing platform with configurable frame orientations and bidirectional rotary drivers that can perform both in-folding and out-folding tests. This multi-functional design provides comprehensive testing coverage for different folding types while reducing the need for multiple separate test setups, thereby lowering overall testing costs while maintaining reliable and thorough testing capabilities.
