Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display devices lack efficient mechanisms for supporting foldable display panels that ensure smooth and controlled transitions between unfolded and folded states, while also preventing dust or debris from entering the electronic equipment.
Innovation Solution
A pivotable support apparatus featuring a sliding groove structure, rotating rods and plates, connecting rods, and a damping assembly that allows for synchronized movement and controlled transitions, along with a synchronized gear system to manage the folding and unfolding of the display panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple support structure is used, then device complexity is reduced, but the ability to provide smooth and controlled transitions between unfolded and folded states deteriorates
Solution Approach 1:
The support structure is divided into multiple segments including a first support portion and a second support portion that can move relative to each other. This segmentation allows each portion to perform specific functions - the first portion provides initial support while the second portion enables controlled folding motion, resolving the contradiction between simplicity and operational smoothness.
Solution Approach 2:
The support structure incorporates dynamic elements including a damping assembly that provides controllable resistance during folding, and a damping slider that can be resiliently pressed to adjust damping force. This dynamic control enables smooth transitions while maintaining relatively simple overall structure.
2Device complexity
If no protective structure is provided, then device complexity is reduced, but dust or debris can enter the electronic equipment
Solution Approach 1:
The first support portion acts as an intermediary protective element between the external environment and the electronic equipment. It provides a physical barrier that prevents dust and debris from entering while supporting the foldable display panel, resolving the contradiction between protective function and structural simplicity.
3Device complexity
If synchronized movement is not implemented, then device complexity is reduced, but mechanical stress increases during folding and unfolding
Solution Approach 1:
The first and second support portions are merged into a coordinated system where their movements are synchronized through the damping assembly and damping slider mechanism. This merging ensures that both portions move together in a controlled manner, reducing mechanical stress while adding only moderate complexity to the overall structure.
