Flexible Display Roller Mechanism for Flat Unfolding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible displays that are bent for storage often fail to unfold flatly, affecting their display quality.
Innovation Solution
A flexible display design featuring a roller with a rotating shaft and frames that snap-fit together to ensure the screen can be easily folded and unfolded, applying opposing forces to flatten the screen when extended, and separate to allow for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flexible display screen is bent for storage, then the storage convenience is improved, but the flatness of the display surface deteriorates when unfolded
Solution Approach 1:
The display system is segmented into the flexible display screen, the frame structure, and the roller mechanism. The frame is divided into multiple connectable sections that can be assembled and disassembled. This segmentation allows the screen to be supported by the frame structure during display, maintaining flatness, while enabling easy rolling and storage when the frame is disassembled.
Solution Approach 2:
The frame acts as an intermediary structure between the flexible display screen and the roller. When assembled, the frame provides rigid support to maintain the screen's flatness during display. When disassembled, the screen can be easily rolled onto the roller for storage. The frame mediates between the conflicting requirements of flatness and flexibility.
2Shape
If the frame structure is assembled to support the screen, then the display surface flatness is improved, but the device complexity increases
Solution Approach 1:
The frame is segmented into multiple sections that can be easily connected and disconnected. Each section is a simple component that can be assembled without complex tools or procedures. This segmentation reduces the overall complexity by breaking down the frame into manageable parts while still providing the necessary support structure.
Solution Approach 2:
The frame structure transitions from a static supported state during display to a dynamic disassembled state for storage. The connectable sections allow the frame to adapt its configuration based on whether the display is being used or stored, simplifying the system by eliminating the need for permanent complex support structures.
3Ease of operation
If the flexible display screen is repeatedly folded and unfolded, then the usability is improved, but the risk of damage increases
Solution Approach 1:
The frame serves as a protective intermediary that supports the flexible display screen during folding and unfolding operations. By providing rigid support along the edges and corners, the frame distributes mechanical stresses and prevents concentrated forces that could damage the screen, thereby improving reliability while maintaining usability.
Solution Approach 2:
The frame structure provides preemptive protection to the flexible display screen by establishing a rigid boundary that prevents excessive bending or folding beyond safe limits. This beforehand cushioning approach protects the screen from damage before it can occur during normal use and storage operations.
