Flexible Display Support Assembly With Comb Teeth for Low-Friction Sliding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices with sliding screens face issues of high relative sliding friction, significant abrasion, and a thick structure that affects device durability and user experience due to sagging and flimsy feel during use.
Innovation Solution
A support assembly with comb-teeth structures on two housings that alternate and slide in a direction, reducing friction and thickness, allowing smoother operation and improved durability by minimizing contact area and friction resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a snap-fitting structure with convex-concave configuration is used to support the sliding screen, then the screen structure becomes more stable, but the contact area increases leading to high friction force and large thickness
Solution Approach 1:
The support structure is divided into multiple comb-teeth elements instead of a single continuous support surface. Each comb-tooth engages with corresponding comb-teeth on the housing, creating discrete contact points that reduce overall friction while maintaining structural stability through distributed engagement.
Solution Approach 2:
The support structure transitions from a planar convex-concave configuration to a three-dimensional comb-tooth arrangement. The comb-teeth extend perpendicular to the sliding direction, creating engagement in a different dimensional orientation that reduces friction contact area while maintaining support stability.
2Stability of the object's composition
If a snap-fitting structure with convex-concave configuration is used to support the sliding screen, then the screen structure becomes more stable, but the thickness increases reducing internal space
Solution Approach 1:
The support structure is divided into multiple comb-teeth elements instead of a single continuous support surface. Each comb-tooth engages with corresponding comb-teeth on the housing, creating discrete contact points that reduce overall friction while maintaining structural stability through distributed engagement.
Solution Approach 2:
The support structure transitions from a planar convex-concave configuration to a three-dimensional comb-tooth arrangement. The comb-teeth extend perpendicular to the sliding direction, creating engagement in a different dimensional orientation that reduces friction contact area while maintaining support stability.
3Adaptability or versatility
If the sliding portion is not rigidly supported, then the device remains flexible and foldable, but sagging feeling occurs during touch control
Solution Approach 1:
The support structure provides localized rigid support at specific comb-tooth engagement points while maintaining overall flexibility. The comb-teeth create discrete support zones that prevent sagging during touch control without compromising the global flexible and foldable characteristics of the display device.

AI summary
Embodiments of the present disclosure provide a flexible display device and a support assembly. The flexible display device includes a support assembly and a flexible display screen. A first support housing and a second support housing of the support assembly are slidable in a first direction by a plurality of first comb-teeth and a plurality of second comb-teeth alternately arranged. A first support portion of each of the first comb-teeth supports and abuts against a second stop portion of one of the second comb-teeth adjacent thereto, and a second support portion of each of the second comb-teeth supports and abuts against a first stop portion of one of the first comb-teeth adjacent thereto.
