Rolling Shaft Position-Limiting Teeth for Flexible Display Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display panels face challenges in accurate positioning and loose rolling during the curling process around a rolling shaft, leading to misalignment and reduced service life.
Innovation Solution
A support assembly with a rolling shaft and position-limiting teeth, along with a support plate that curls up around the shaft, ensures accurate positioning by confining the positioning portion within a position-limiting space, preventing misalignment and loose rolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the flexible display panel is curled around the rolling shaft without positioning structures, then the portability is improved, but the positioning accuracy deteriorates causing misalignment and loose rolling
Solution Approach 1:
The patent introduces a support plate as an intermediary component between the flexible display panel and the rolling shaft. The support plate includes positioning portions that engage with position-limiting portions on the rolling shaft, mediating the interaction to achieve accurate positioning while maintaining the curling function for portability
Solution Approach 2:
The support plate is divided into functional segments: a support portion for supporting the flexible display panel, positioning portions for engagement with the rolling shaft, and a flattened state for storage. This segmentation allows each part to perform its specific function while working together as a unified system
2Volume of moving object
If the flexible display panel is curled around the rolling shaft, then the compact size is improved, but the alignment stability deteriorates leading to loose rolling
Solution Approach 1:
The support plate acts as a mediator that transfers and stabilizes the alignment between the flexible display panel and the rolling shaft during curling. The positioning portions on the support plate engage with the position-limiting portions, ensuring stable alignment even in the compact curled state
Solution Approach 2:
The positioning portions and position-limiting portions are pre-configured to engage automatically when the support plate curls around the rolling shaft. This preliminary positioning action prevents misalignment before it occurs, ensuring stable alignment throughout the curling process

AI summary
A support assembly and a display device. The support assembly can be used to a flexible display panel. The support assembly includes: a rolling shaft, in which an axis of the rolling shaft extends in a first direction; a position-limiting portion, arranged at at least one end of the rolling shaft in the first direction, in which the position-limiting portion includes at least two position-limiting teeth, and a position-limiting space is formed between two adjacent position-limiting teeth; and a support plate, connected to the rolling shaft, in which the support plate includes a support portion for supporting the flexible display panel, the support portion includes two side edges opposite to each other in the first direction, and the support plate further includes a positioning portion protruding from at least one of the side edges of the support portion.
