Flexible Display Fold Fixture for Variable Fold-Rate Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack an effective method to test the influence of folds on the display effect and reliability of flexible display modules with different fold rates, particularly in four-curved surface designs.
Innovation Solution
A fold testing device comprising a support mechanism, adjusting mechanism, and attaching mechanism is used to form flexible display modules with varying fold rates by adjusting the spacing between position limiting parts and engaging an elastic attaching body, allowing for the formation of folds at controlled rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If flexible display modules with different fold rates are needed for testing, then the adaptability of the testing device is improved, but the device complexity increases
Solution Approach 1:
The position limiting parts are made adjustable along the first direction, allowing dynamic reconfiguration of the spacing between them. This enables the device to adapt to different fold rates by simply repositioning components rather than requiring multiple fixed configurations, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The adjustable position limiting parts serve multiple functions: they define the spacing for different fold rates, constrain the flexible display module during testing, and can be repositioned to accommodate various test scenarios. This multi-functionality improves adaptability without proportionally increasing device complexity.
2Measurement precision
If the spacing between position limiting parts is adjusted to form different fold rates, then the measurement precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The position limiting parts are pre-configured with specific spacings corresponding to different fold rates. Users can directly select and adjust to these pre-determined positions without performing complex calculations or measurements, thereby maintaining measurement precision while simplifying the operation.
3Reliability
If the elastic attaching body is used to engage with the positioning part, then the reliability of the testing setup is improved, but the device complexity increases
Solution Approach 1:
The elastic attaching body utilizes its own elasticity to automatically engage with and maintain contact with the positioning part. This self-service mechanism ensures reliable positioning and stable testing setup without requiring additional active control systems or complex actuation mechanisms, thus improving reliability while minimizing the increase in device complexity.
