Flexible Display Arm Assembly for Stable Area Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible display devices face issues with structural stability and user convenience, particularly when unfolded or rolled, leading to potential damage and inconvenience in maintaining a stable display area.
Innovation Solution
A display device design featuring a flexible display panel supported by an arm assembly with rotatable connecting arms and supporting shafts, allowing the panel to change its display area based on the distance between two bodies, which are securely attached and easily movable, preventing damage and enhancing usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the flexible display panel is folded or rolled to reduce size, then portability is improved, but structural stability deteriorates and the panel may be damaged
Solution Approach 1:
The patent implements a dynamic support structure with movable supporting plates and sliding supporting rods that adapt to different display panel configurations. The supporting plates can move between extended and retracted positions, and the supporting rods can slide to maintain proper support geometry whether the panel is unfolded or rolled, preventing damage while enabling portability
Solution Approach 2:
The supporting components are designed with nested structures where the first and second supporting plates can be positioned within each other, and the supporting rods can be stored within the housing when not in use. This nesting approach minimizes the device volume for portability while providing full support functionality when needed
2Area of moving object
If the flexible display panel is unfolded to increase display area, then display area is improved, but structural stability deteriorates
Solution Approach 1:
The support structure dynamically adjusts to the unfolded configuration by extending the supporting plates outward and positioning the supporting rods to create a stable geometric framework. The movable components enable the structure to maintain optimal support geometry across different display areas, preventing instability when the panel is fully unfolded
3Volume of moving object
If the flexible display panel is rolled to improve portability, then portability is improved, but ease of operation deteriorates due to difficulty in maintaining stable display area
Solution Approach 1:
The support structure incorporates self-adjusting mechanisms where the movable supporting plates and sliding rods automatically position themselves to maintain stable geometry. The elastic body provides self-regulating tension to keep the supporting rods in optimal positions, reducing the need for manual adjustment and making it easier for users to maintain stable display areas during operation
