Flexible Screen Retractable Assembly for Bending Stress Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of flexible screens in electronic devices is complicated by stress caused by bending, leading to frequent separation and damage due to dimensional tolerance issues and excessive stress, which affects the display area and overall display effect.
Innovation Solution
A retractable device is integrated into the device housing, connected to an extending layer of the flexible screen component, allowing for pulling during assembly and use to counteract bending stress, thereby improving connection reliability and preventing separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the flexible screen is fitted with a bent side face of the housing to improve display area and display effect, then the display area and overall display effect are improved, but stress is caused by bending which adds difficulty to assembling and causes frequent separation or damage
Solution Approach 1:
The patent applies preliminary action by pre-forming the flexible screen with a curvature that matches the bent side face of the housing before assembly. This pre-curving of the flexible screen ensures that when it is assembled with the bent housing, the stress distribution is optimized from the beginning, preventing separation and damage while maintaining the improved display area and display effect.
2Area of moving object
If the flexible screen is bent to fit the housing, then the display area is improved, but dimensional tolerance issues and excessive stress make assembly difficult
Solution Approach 1:
The patent applies parameter changes by adjusting the curvature parameter of the flexible screen to match the specific geometric parameters of the bent housing side face. By optimizing the curvature radius and shape parameters of the flexible screen, the design accommodates dimensional tolerances and reduces assembly difficulty while maintaining the improved display area.

If the flexible screen is bent to improve display effect, then the overall display effect is improved, but excessive stress causes separation or damage
Solution Approach 1:
The patent applies preliminary action by pre-forming the flexible screen with a curvature that matches the bent side face of the housing before assembly. This pre-curving of the flexible screen ensures that when it is assembled with the bent housing, the stress distribution is optimized from the beginning, preventing separation and damage while maintaining the improved display area and display effect.
Solution Approach 2:
The patent applies beforehand cushioning by designing the flexible screen with a pre-formed curvature that anticipates and compensates for the stress that will occur during assembly and use. This pre-stress configuration acts as a cushion against excessive stress, preventing separation or damage while maintaining the improved display effect.
