Flexible Screen Support Device with Rotating Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display screens experience display failure when squeezed or stretched by support devices in bent states, leading to mechanical stress and potential damage.
Innovation Solution
A flexible screen support device with a rotating assembly, first and second housing, and a fixing piece that allows the screen to bend without stretching, ensuring the screen is not squeezed or stretched by the support device, with the fixing piece acting as a bending neutral layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a flexible screen support device is fixed on the lower surface of a flexible display screen to ensure folded and flattened states, then the structural stability is improved, but the flexible display screen may be squeezed or stretched causing display failure
Solution Approach 1:
The support device is divided into a first housing and a second housing that can rotate relative to each other around a rotation shaft. This segmentation allows each housing to independently adjust its position, enabling the device to adapt to both folded and flattened states without transmitting excessive stress to the flexible display screen, thereby preventing display failure while maintaining structural stability.
Solution Approach 2:
The support device transitions from a static structure to a dynamic one by introducing a rotation shaft that allows the first and second housings to rotate relative to each other. This dynamic capability enables the device to smoothly transition between folded and flattened states, accommodating the flexible display screen's movement without causing squeezing or stretching that would lead to display failure.
2Adaptability or versatility
If the flexible display screen is bent to achieve a folded state, then the portability is improved, but the screen may be stretched or squeezed by the support device causing display failure
Solution Approach 1:
The rotation mechanism between the first and second housings allows the support device to dynamically adapt to the bent configuration of the flexible display screen in folded states. This dynamic adjustment prevents the screen from being stretched or squeezed during bending, maintaining display functionality while improving portability through the folded state capability.
Solution Approach 2:
The support device changes its geometric parameters (relative positions and angles of the first and second housings) in response to the bending state of the flexible display screen. By adjusting these parameters through rotation around the rotation shaft, the device maintains appropriate clearance and support characteristics whether the screen is flat or bent, preventing display failure while enabling folded portability.

AI summary
A flexible screen support device and a flexible display terminal are provided. The flexible screen support device includes: a rotating assembly including a rotation shaft; a first housing and a second housing respectively connected to the rotating assembly; and a fixing piece, located on one side, away from the rotating assembly, of the first housing and the second housing. At least one of the first housing and the second housing rotates around the rotating assembly to make the fixing piece bend or flatten, and a horizontal length of a side surface, perpendicular to the rotation shaft, of the fixing piece in a flattened state is equal to a length of the side surface, which is a curved surface, of the fixing piece in a bent state.
