Support Mechanism for Foldable Mobile Terminal Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a conflict between the size of the display screen and the volume of electronic products, where a smaller volume results in a smaller screen size, affecting user experience, and existing flexible screens do not effectively address this issue by providing a larger display without increasing the product's volume.
Innovation Solution
A support mechanism comprising a first and second support plate connected by a transmission mechanism, which rotates to form a plane when actuated, allowing a flexible screen to be unfolded and supported without changing the mobile terminal's volume, thereby enabling a larger display screen while maintaining portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the volume of the mobile terminal is reduced to improve portability, then the size of the display screen must be reduced, but this worsens the user experience
Solution Approach 1:
The patent employs a support mechanism that transforms the display structure from a static flat configuration to a dynamic three-dimensional unfolded configuration. The support plates and transmission mechanism enable the display to change its spatial arrangement, allowing a larger effective display area while maintaining a compact folded volume, thus resolving the contradiction between small volume and large screen size
Solution Approach 2:
The invention transitions the display from a two-dimensional flat surface to a three-dimensional unfolded structure using support plates that create spatial depth. By utilizing the third dimension (z-axis) through the unfolding mechanism, the display achieves a larger effective area without increasing the footprint or volume of the device body, thereby solving the screen size versus volume contradiction
2Area of stationary object
If a flexible screen is used to enable unfolding, then the display area can be increased, but the structural complexity increases
Solution Approach 1:
The support mechanism is divided into discrete modular components including first and second support plates, a pushing bar, and transmission mechanisms with gears and rack structures. This segmentation allows each component to perform a specific function independently while collectively achieving the unfolding motion, making the complex structure more manageable and manufacturable
Solution Approach 2:
The patent replaces complex multi-linkage mechanical unfolding mechanisms with a simplified transmission system consisting of a pushing bar that actuates gear-rack mechanisms. This substitution reduces the number of moving parts and simplifies the overall mechanical structure while still achieving the desired display unfolding function, thereby reducing structural complexity

AI summary
A support mechanism and a mobile terminal are provided. The support mechanism comprises: a first support plate, a second support plate, and a transmission mechanism for connecting the first support plate with the second support plate. When the support mechanism is in a support state, the first support plate and the second support plate are in a first relative position with respect to each other to form a support surface. The mobile terminal includes a first body, a second body connected to the first body, a support mechanism and a display screen. The display screen comprises: fixed portions fixed to at least one of the first body or the second body, and a deformable portion. The support mechanism is arranged on the second body.
