Foldable Support Member With Sliding Hinge for Screen Stress Relief
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 excessive stretching or squeezing of the display screen, leading to reduced service life and normal display failure.
Innovation Solution
A foldable support member with a rotating shaft portion and a support plate, featuring a sliding unfolding portion that moves circumferentially along a rotating assembly, allowing the support plate to fold and unfold while minimizing deformation by adjusting its position relative to the fixing shaft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the support plate is directly connected to the rotating shaft without sliding mechanism, then the structure is simple, but the display screen undergoes excessive stretching and squeezing during folding
Solution Approach 1:
The support plate is divided into two functional parts: a connecting portion that remains fixed to the rotating shaft and an unfolding portion that can slide relative to the rotating assembly. This segmentation allows the connecting portion to maintain structural simplicity while the unfolding portion accommodates dimensional changes during folding, preventing excessive stress on the display screen.
Solution Approach 2:
The unfolding portion is designed to slide dynamically along the rotating assembly in the circumferential direction during folding operations. This dynamic adjustment allows the support plate to adapt its configuration, reducing dimensional differences between folded and unfolded states, thereby minimizing stretching and squeezing of the display screen while maintaining reasonable structural complexity.
2Stability of the object's composition
If the unfolding portion is fixed relative to the connecting portion, then the structure is stable, but the dimensional difference between folding and unfolding states is too great
Solution Approach 1:
The unfolding portion is designed to slide dynamically along the rotating assembly in the circumferential direction during folding operations. This dynamic adjustment allows the support plate to adapt its configuration, reducing dimensional differences between folded and unfolded states while maintaining structural stability through the fixed connecting portion.
Solution Approach 2:
The sliding mechanism enables the unfolding portion to change its position parameter relative to the rotating assembly during folding. By adjusting this positional parameter, the system reduces the overall dimensional difference between folding and unfolding states while preserving structural integrity through the stable connecting portion.
3Reliability
If a sliding mechanism is added to reduce deformation, then the display screen service life is improved, but the device complexity increases
Solution Approach 1:
The support plate is divided into two functional parts: a connecting portion that remains fixed to the rotating shaft and an unfolding portion that can slide relative to the rotating assembly. This segmentation allows the connecting portion to maintain structural simplicity while the unfolding portion accommodates dimensional changes during folding, preventing excessive stress on the display screen.
Solution Approach 2:
The sliding mechanism is implemented locally only in the unfolding portion where dimensional adjustment is needed, rather than throughout the entire support structure. This localized application reduces deformation at critical areas near the display screen while minimizing the overall complexity increase, as the connecting portion remains simple and fixed.

AI summary
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.
