Extendable Mobile Terminal Support Structure for Flat Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals with flexible displays face challenges in maintaining a flat state while allowing size adjustments, leading to potential damage from concentrated stress and sagging during state changes.
Innovation Solution
A mobile terminal design featuring a first and second frame, a slide frame, and a support link with variable length, along with rollers and a driving unit, enables the terminal to switch between states while maintaining a flat display by distributing stress and preventing sagging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display is extended to change the size of the mobile terminal, then the screen size is increased, but the display may sag or become non-flat
Solution Approach 1:
A support link is introduced as an intermediary component between the first frame and the second frame. This support link provides mechanical support to the extended display, preventing sagging and maintaining the flat state of the display during size changes. The support link acts as a mediator that transfers and distributes the structural load, ensuring the display remains flat while the terminal size is extended.
2Area of moving object
If the display is extended to change the size of the mobile terminal, then the screen size is increased, but stress concentrates at specific points causing potential damage
Solution Approach 1:
The support structure is segmented into multiple components including the support link, first link, second link, and multiple rollers. This segmentation distributes the mechanical stress across multiple contact points and structural elements rather than concentrating it at a single point. The divided structure allows stress to be dispersed through the chain of connected components, reducing the risk of damage to the display.
3Adaptability or versatility
If the mobile terminal size is changed, then the display can be extended, but the structure becomes complex requiring stable support
Solution Approach 1:
The support link is designed with variable length capability, allowing it to dynamically adjust its configuration based on the terminal's state. The support link can change its length and arrangement (e.g., positioned perpendicular to the extension direction in compact state, and diagonally arranged in extended state), providing adaptive support that simplifies the overall structure while maintaining size adjustment capability.

AI summary
Disclosed herein is a mobile terminal switchable from a first state to a second state by extending in the first direction, including a first frame, a second frame movable from the first frame in the first direction or a second direction opposite to the first direction, a slide frame movable in the first direction or the second direction with respect to the second frame, and a support link having one end hinged to the first frame and an opposite end hinged to the second frame, the support link having a variable length. The mobile terminal may maintain a flat state regardless of change in the state of the mobile terminal by preventing the front surface from being separated or sagging.
