Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The dimension difference between the folding and unfolding states of foldable support members in folding screen devices causes deformation, leading to reduced service life of the display screen due to stretching or squeezing.
Innovation Solution
A foldable support member with a rotating shaft portion and a support plate, featuring a connecting portion fixed to a fixing shaft and an unfolding portion connected to a rotating assembly, allowing the unfolding portion to slide and rotate, minimizing deformation by adjusting its position relative to the fixing shaft during state changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the support plate is folded using a rotary shaft mechanism with connecting rods and swing arms, then the folding effect is improved and the thickness is reduced, but the length change causes the display screen to be stretched or squeezed, reducing its service life
Solution Approach 1:
The patent applies dynamics by making the support plate structure movable and adjustable during folding. The unfolding portion can slide along the rotary shaft in the circumferential direction, dynamically adjusting its position to compensate for length changes and prevent stretching or squeezing of the display screen during the folding process.
Solution Approach 2:
The support plate is segmented into a connecting portion and an unfolding portion that can move relative to each other. This segmentation allows the unfolding portion to independently slide and adjust its position, decoupling the folding motion from the display screen to prevent deformation.
2Device complexity
If the unfolding portion is fixed on the fixing shaft, then the structure is simple, but the connecting portion cannot avoid stretching or squeezing during folding
Solution Approach 1:
The patent transforms the static fixed connection into a dynamic sliding connection. The unfolding portion is configured to slide along the rotary shaft in the circumferential direction, enabling it to dynamically adjust its position during folding to avoid stretching or squeezing the display screen, while maintaining relatively simple structural implementation.

AI summary
The present application provides a foldable support member and a display device. The foldable support member has a folding state and an unfolding state. The foldable support member includes a rotating shaft portion including a fixing shaft formed by extending in a first direction and a rotating assembly rotatably connected to the fixing shaft, a support plate including a connecting portion and an unfolding portion connected to the connecting portion, in which the connecting portion is fixed to the fixing shaft and the unfolding portion is arranged to be foldable around the fixing shaft relative to the connecting portion. The unfolding portion is slidably connected to the rotating assembly in a circumferential direction of the fixing shaft, and the unfolding portion is slidable in the circumferential direction along the rotating assembly when the foldable support member is switched between the folding state and the unfolding state. The foldable support member in the embodiments of the present application can reduce the deformation amount of the support plate when the support plate is folded, thereby reducing the deformation amount of a to-be-supported member when the to-be-supported member is folded and improving the service life of the to-be-supported member.
