Flexible Display Anti-Roll Supporting Frame Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display screens roll easily when stretched for use, affecting the viewing effect due to their flexible and rollable nature.
Innovation Solution
A flexible display device with a supporting frame and housing design that includes an anti-roll bar and protection frames to prevent rolling when extended, and rollers for easy retraction, ensuring stable display and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display screen is made rollable and flexible for portability, then the device becomes portable and easy to store, but the display screen rolls easily when stretched for use, affecting the viewing effect
Solution Approach 1:
A supporting frame is introduced as an intermediary structure between the flexible display screen and the housing. The supporting frame includes an anti-roll bar that acts as a mediator to prevent the display screen from rolling during use, while allowing the screen to remain flexible and rollable for portability when not in use.
Solution Approach 2:
The supporting frame provides localized structural support at critical areas where rolling would affect display quality. The anti-roll bar is positioned specifically to counteract rolling forces without compromising the overall flexibility of the display screen, applying support only where needed rather than making the entire structure rigid.
2Ease of operation
If the flexible display screen is made rollable for easy storage, then the device can be easily stored and transported, but it requires additional supporting structures to prevent rolling during use
Solution Approach 1:
The flexible display screen and supporting frame are nested within the housing, with the supporting frame containing the display screen during storage. The anti-roll bar is nested within the supporting frame structure, allowing compact storage while providing support functionality when deployed.
Solution Approach 2:
The supporting frame transitions from a compact nested state during storage to an expanded supportive state during use. The anti-roll bar is designed to be dynamic, providing rigidity when needed to prevent rolling, while allowing flexibility and compactness when the display is being stored or transported.

AI summary
The provided flexible display device has supporting frames on a rolled side of the flexible display screen. When the flexible display screen and the supporting frames are drawn out of a containing body, the supporting frames are combined with the rolled side of the flexible display screen to prevent the flexible display screen from being rolled to influence the viewing effect.
