Foldable Display Support Assembly With Locking Rotary Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display screens in terminal devices face challenges with bulky and heavy support assemblies due to the need for linkage and synchronization structures, which hinder a lightweight design and effective support for the display panel.
Innovation Solution
A support assembly comprising a first, second, and third support member, where the first support member is rotatable between locked and unlocked positions, allowing rotation relative to the second and third support members without the need for linkage and synchronization structures, reducing size and weight by forming rotation pairs and using stop structures for fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If linkage and synchronization structures are added to the support assembly, then the display panel can be effectively supported and stabilized during folding, but the size and weight of the support assembly increase
Solution Approach 1:
The patent merges the linkage function and synchronization control into a single integrated support assembly structure. The first, second, and third support members are combined with rotatable connections that inherently provide both support stability and synchronized movement during folding, eliminating the need for separate linkage and synchronization components.
Solution Approach 2:
Each support member serves multiple functions: the first support member provides both structural support and rotatable adjustment, while the second and third support members simultaneously provide support stability and synchronized folding control. This multi-functionality reduces the overall number of components needed.
2Reliability
If linkage and synchronization structures are added to the support assembly, then the display panel can be effectively supported and stabilized during folding, but the device becomes less compact
Solution Approach 1:
The patent combines multiple support functions into a compact integrated assembly where the first, second, and third support members are arranged in a space-efficient configuration. The rotatable connections between members allow for compact folding without requiring extensive linkage mechanisms.
3Weight of moving object
If the support assembly is simplified to reduce weight and size, then the device becomes more compact and lightweight, but the ability to effectively support and stabilize the display panel during folding is compromised
Solution Approach 1:
The support assembly is segmented into three distinct support members (first, second, and third) that can independently rotate and adjust. This segmentation allows each member to be optimized for specific functions while collectively providing stable support, reducing the need for heavy reinforcement in any single component.
Solution Approach 2:
The support members are designed with rotatable connections that allow dynamic adjustment during folding. The first support member can rotate relative to the second, and the second can rotate relative to the third, enabling the assembly to adapt its configuration during movement while maintaining support stability without requiring additional locking mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution results in a thinner, lighter foldable display screen and terminal device, enabling a more compact and efficient lightweight design while maintaining effective support for the display panel, improving user experience and manufacturing simplicity.
Implementation Method 1
The first support member is rotatable between a first locked position and a first unlocked position. The first support member is configured to rotate relative to the second support member
Implementation Method 2
When the first support member is in the first locked position, the second support member and the third support member are fixed relative to each other

AI summary
A support assembly, a foldable display screen and a terminal device are provided. The support assembly includes a first support member, a second support member and a third support member. The second support member has a first side and a second side. The first support member is rotatably arranged to the first side of the second support member, and the third support member is rotatably arranged to the second side of the second support member. The first support member is movable between a first locked position and a first unlocked position. The first support member is configured to rotate relative to the second support member, and the second support member and the third support member are configured to be fixed relative to each other when the first support member is in the first locked position. The second support member is configured to rotate relative to the third support member when the first support member is in the first unlocked position.
