Foldable Screen Hinge Assembly for Compact Wrinkle Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing hinge components for foldable screens occupy a large space and fail to provide effective support, leading to wrinkles and deformation during folding, which is not conducive to lightweight structure stacking in terminal devices.
Innovation Solution
A hinge component with a support assembly comprising at least three movably connected support members and a linkage assembly that achieves mutual linkage and left-right synchronization, allowing for a refined support structure that reduces space occupation while effectively supporting the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hinge component uses a conventional single support member design, then the structure is simple, but it occupies large space and cannot provide effective support to prevent wrinkles and deformation
Solution Approach 1:
The support member is divided into multiple support members (first support member, second support member, third support member) that are movably connected. Each support member provides localized support to different regions of the flexible screen, improving overall support effectiveness while reducing the volume of each individual component through the movable connection mechanism.
2Reliability
If the hinge component increases the number of support members to improve support effectiveness, then it can better support the flexible screen, but the device complexity increases
Solution Approach 1:
The support members are movably connected through guide portions that allow relative movement between adjacent support members. This dynamic connection enables the support members to adapt to the folding motion of the flexible screen, providing effective support across multiple regions without requiring a complex rigid structure. The movable connection reduces structural complexity compared to a fully rigid multi-component system.
3Volume of moving object
If the hinge component uses a compact design to reduce space occupation, then it facilitates lightweight structure stacking, but it may compromise the support effectiveness
Solution Approach 1:
The support members are arranged side by side in a longitudinal direction, creating a distributed support structure along the length of the flexible screen. This longitudinal arrangement allows the hinge component to maintain a compact width (reducing space occupation) while providing extended support coverage through multiple support members, thus maintaining support effectiveness in a compact form factor.
