Slide Bar Mechanism for Flexible Display Mobile Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals with flexible displays face challenges in maintaining structural stability and efficiently switching between states while minimizing frictional forces during slide movements.
Innovation Solution
A mobile terminal design featuring a first and second frame with a slide bar and link unit, allowing for sliding movement and angle adjustment between frames, which reduces frictional forces and supports the flexible display unit through a semi-automatic state transition mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display is used to vary the size of the mobile terminal, then the adaptability and versatility of the terminal is improved, but the structural stability and reliability deteriorate due to the need for support structures during deformation
Solution Approach 1:
The terminal body is divided into a first frame and a second frame that can slide relative to each other. The flexible display is segmented into a first display unit on the first frame and a second display unit on the second frame, allowing independent control and support of each segment during size transformation.
Solution Approach 2:
A link unit acts as an intermediary mechanism between the first frame and the second frame. This link unit includes links and hinges that provide mechanical support and enable controlled relative movement, ensuring structural stability during the transformation process.
2Ease of operation
If the second frame is made to slideably move with respect to the first frame to enable size variation, then the ease of operation is improved, but the frictional forces during sliding movement increase
Solution Approach 1:
A slide bar is introduced as an intermediary component between the first frame and the second frame. The slide bar moves within a rail structure, providing a guided path that reduces friction and enables smooth relative sliding movement between the frames during state transitions.
3Volume of moving object
If the first frame and second frame are designed to overlap in a compact state, then the volume of the terminal is reduced, but the complexity of the mechanism required for state transition increases
Solution Approach 1:
The terminal is segmented into two main frames that can independently move. The first frame contains the first display unit and the second frame contains the second display unit, allowing each frame to be independently controlled during compacting and expanding operations.
Solution Approach 2:
The link unit serves as a mediator that simplifies the state transition mechanism. It uses hinge joints and linkages to provide automatic mechanical coupling between the frames, reducing the complexity of control mechanisms needed for compacting and expanding operations.

AI summary
A mobile terminal comprises: a first frame including a first side surface; a second frame which can slide from the first frame in a first direction or a second direction that is opposite to the first direction, and which includes a second side surface that faces the first side surface; and a slide bar which is located between the first side surface and the second side surface and which extends in the first direction.
