Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The stability of extendable screens in terminal devices is unstable during extension and contraction processes, affecting user experience due to mechanical instability and noise from complex structures.
Innovation Solution
A supporting apparatus with a support frame featuring an overturning curved surface and a driving mechanism with an adjustable rod that extends or contracts, allowing the screen to extend or contract while maintaining stability and minimizing noise by using a hydraulic module and magnetic module for power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex mechanical structure is used to enable screen extension and contraction, then the screen can achieve extendable functionality, but the stability and noise performance deteriorate due to mechanical instability and noise
Solution Approach 1:
The support frame is divided into a first support frame and a second support frame that can relatively move, with the display screen divided into first and second display regions. This segmentation allows independent control of each region during extension and contraction, improving stability while maintaining extendability.
Solution Approach 2:
A driving mechanism acts as an intermediary between the first and second support frames, controlling their relative movement. This intermediary mechanism enables precise control of screen extension and contraction, reducing mechanical instability and noise compared to direct mechanical coupling.
2Adaptability or versatility
If a complex mechanical structure is used for screen extension, then extendable functionality is achieved, but device complexity increases
Solution Approach 1:
The driving mechanism is extracted as a separate component from the support frames, allowing independent optimization of the mechanical structure. This extraction simplifies the overall device complexity by modularizing the extension mechanism while maintaining full extendable functionality.
3Area of moving object
If the screen is extended to provide a large screen experience, then display area increases, but the screen state becomes unstable during extension/contraction process
Solution Approach 1:
The support frames are designed to dynamically adjust their relative positions during extension and contraction. The first and second support frames can move relative to each other, allowing the system to adapt its structure during transitions, thereby maintaining stability throughout the dynamic process while achieving large display area.

AI summary
A supporting apparatus for supporting a flexible display screen includes a support frame including an overturning curved surface; and a driving mechanism disposed at a side, away from the overturning curved surface, of the support frame. The driving mechanism includes an adjustable rod configured to extend or contract in an adjustment direction; an axial direction of the overturning curved surface is perpendicular to an adjustment direction of the adjustable rod; and the adjustable rod is configured to be connected with the display screen overturned along the overturning curved surface, and the adjustable rod is configured to push the support frame to move during extension and to pull the display screen to move during contraction.
