Foldable Display Hinge Mechanism With Bending Space Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The bending areas of flexible displays in electronic devices are prone to squeezing during the folding process, leading to excessive bending and potential damage.
Innovation Solution
A folding mechanism with a base, housing seats, screen supporting plates, and swing arms that allow the flexible display to be folded and unfolded while preventing excessive bending by creating an accommodation space for the bending area, using rotating and sliding mechanisms to balance weight and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flexible display is folded, then the device becomes portable and compact, but the bending area is squeezed and excessive bending occurs
Solution Approach 1:
The patent introduces a sliding mechanism that moves in a direction perpendicular to the folding direction, creating additional dimensional space for the bending area. The support plate slides relative to the housing along a sliding groove, providing extra accommodation space that prevents squeezing of the flexible display during folding operations.
Solution Approach 2:
The support plate acts as an intermediary component between the housing and the flexible display. It provides direct support to the bending area of the flexible display during folding, distributing the mechanical stress and preventing excessive bending that would otherwise occur at the hinge location.
2Device complexity
If the folding mechanism uses simple rotation, then the structure is simple, but the bending area lacks accommodation space
Solution Approach 1:
The patent combines rotational and sliding movements to create a dynamic folding mechanism. The support plate both rotates with the housing and slides independently along the sliding groove, adapting its position dynamically during the folding process to provide optimal accommodation space for the bending area.
Solution Approach 2:
The sliding groove is integrated within the housing structure, and the support plate is nested within the housing cavity. This nested arrangement allows the sliding mechanism to operate within the existing structural boundaries without significantly increasing the overall device volume.
