Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals with flexible displays face challenges in minimizing friction during slide movements, which can lead to distortion and foreign substance ingress, hindering smooth operation and increasing energy consumption.
Innovation Solution
Incorporation of low-friction sheets on overlapping surfaces of sliding frames, utilizing materials like metal or Teflon, and strategically positioning these sheets to minimize friction and prevent gap distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gap between members is widened to reduce friction, then friction during slide movement is reduced, but distortion occurs and foreign substances enter the gap
Solution Approach 1:
A low-friction sheet is introduced as an intermediary component between the first frame and second frame. This sheet reduces friction during slide movement while allowing the frames to maintain close proximity, preventing distortion and foreign substance ingress without requiring a wide gap between members.
2Use of energy by moving object
If friction during slide movement is reduced, then energy consumption is reduced, but the gap between members increases causing distortion
Solution Approach 1:
The low-friction sheet serves as a mediator that enables reduced friction and lower energy consumption while maintaining proper frame alignment. The sheet is positioned between the frames to provide a low-friction surface without requiring increased gap distance, thus preventing shape distortion.
3Object-affected harmful factors
If the gap between members is minimized, then foreign substance ingress is prevented, but friction during slide movement increases
Solution Approach 1:
The low-friction sheet acts as an intermediary that protects the interface between frames from foreign substance ingress while simultaneously providing a low-friction surface for smooth slide movement. The sheet is positioned to fill the interface gap, preventing contaminant entry while enabling smooth operation.
4Ease of operation
If friction during slide movement is reduced, then ease of operation is improved, but the structure becomes more complex
Solution Approach 1:
The low-friction sheet is a simple intermediary component that can be attached to existing frame surfaces. It provides friction reduction and operational smoothness without requiring complex structural modifications to the frame assembly, maintaining design simplicity while improving performance.

AI summary
A mobile terminal that can be switched to a first state or a second state comprises: a first frame; a second frame that can be switched to the second state by sliding from the first frame in a first direction, and that can be switched to the first state by sliding in a second direction opposite to the first direction; and a low-friction sheet positioned on at least one side of an overlapping surface of the first frame and the second frame, wherein friction can be minimized during sliding of the mobile terminal, and thereby driving energy can be saved and noise generated by friction can be prevented.
