Sliding-Folding Flexible Display Hinge to Prevent Lift and Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with deformable displays face challenges such as damage, deformation, and lifting issues, requiring a stable support structure that maintains driving characteristics during repeated operations.
Innovation Solution
An electronic device with a first and second housing that slides relative to each other, featuring a flexible display fixed to one housing and a hinge device with a movable rotation shaft, allowing the display area to increase or decrease based on sliding and folding operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a deformable display is used to enable sliding and folding operations, then the information display area can be increased, but the display is susceptible to damage, deformation, and lifting issues
Solution Approach 1:
The housing is divided into a first housing and a second housing that can slide relative to each other, allowing the display to be segmented across different spatial positions. This segmentation enables the display area to be expanded while maintaining structural support at multiple points, reducing the risk of damage and deformation to any single display segment.
2Reliability
If a support structure is added to prevent display damage and lifting, then the reliability improves, but the device complexity increases
Solution Approach 1:
The support structure is merged with the housing design itself, where the first and second housings serve both as structural support and as the housing for the display components. This integration eliminates the need for separate, complex support mechanisms while maintaining display stability and preventing lifting during deformation.
Solution Approach 2:
The hinge device incorporates a movable rotation shaft that can dynamically adjust its position during rotation operations. This dynamic adjustment allows the support structure to adapt to different folding angles and positions, maintaining optimal support for the display while simplifying the overall mechanism through motion-based adaptation rather than complex static structures.
