Flexible Screen Mobile Terminal Rotation Shaft Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals with small screens provide poor sensory experiences for video watching and gaming due to their size, while larger screens offer better experiences but are inconvenient to carry, lacking a solution for flexible screen size adjustment.
Innovation Solution
A mobile terminal design featuring a flexible screen that can be extended and retracted using a rotation shaft structure and support mechanisms, allowing users to switch between small and large screen sizes by separating or attaching the upper and lower main bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a small screen (4.5-inch or 5-inch) is used, then the mobile terminal is easy to carry, but the sensory experience for video watching and gaming is poor
Solution Approach 1:
The patent implements a flexible screen that can dynamically change its display area by unfolding or rolling out, allowing the screen to transition from a compact small-size state for portability to a large unfolded state for enhanced visual experience during video watching and gaming
Solution Approach 2:
The flexible screen is designed to be rolled up or folded into a compact form that can be stored within or alongside the mobile terminal body, enabling the large screen to be nested into a small portable form factor when not in use
2Area of moving object
If a large screen (6-inch or 6.5-inch) is used, then the sensory experience for video watching and gaming is improved, but the mobile terminal becomes inconvenient to carry due to large volume
Solution Approach 1:
The flexible screen enables the terminal to dynamically adjust between large and small form factors, providing a large screen area when needed for media consumption while automatically returning to a compact size for easy carrying
Solution Approach 2:
The patent changes the physical state and configuration of the screen from a fixed rigid structure to a flexible可变 structure, allowing the screen parameters (area, shape, position) to be changed on demand to resolve the contradiction between large display area and compact portability
3Adaptability or versatility
If the screen size is fixed, then the device structure is simple, but the terminal cannot adapt to different usage scenarios requiring different screen sizes
Solution Approach 1:
The patent employs a flexible screen film that can be unfolded, rolled, or folded to change screen size, providing adaptability for different usage scenarios while maintaining a relatively simple overall structure compared to rigid mechanical expansion mechanisms
Solution Approach 2:
The flexible screen mechanism serves multiple functions: it provides a large screen for video and gaming, a small screen for casual use, and can be configured in various positions, making the terminal adaptable to diverse usage scenarios with a single integrated system

AI summary
A mobile terminal includes a main body and a flexible screen disposed on the main body. The main body includes an upper main body and a lower main body separately disposed. The mobile terminal includes a rotation shaft structure and a first support structure for supporting the flexible screen. The rotation shaft structure is located in the upper main body and the first support structure winds around the rotation shaft structure. One portion of the flexible screen is embedded in the lower main body and located on a surface facing a user. A back surface of the other portion is attached to a surface of the first support structure remote from the rotation shaft structure. When the upper main body is separated from or attached to the lower main body, deployment and retraction of the first support structure may be realized by rotating the rotation shaft structure.
