Expandable Display Support Structure With Coordinated Screen Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminal devices with fixed screen sizes fail to meet diverse user needs for different tasks, such as calling, gaming, and document processing, as they cannot adjust the display area to accommodate varying requirements.
Innovation Solution
A support structural member with a power unit, transmitting mechanisms, and a screen body connecting mechanism allows the flexible screen to expand or retract, adjusting the display area by moving support bodies relative to each other, driven by a driver through interconnected mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the screen size is fixed, then the device structure is simple, but the device cannot meet diverse user needs for different tasks
Solution Approach 1:
The support frame is designed with movable components including a first support body and a second support body that can move relative to each other along a moving direction. The flexible screen is connected to these movable support bodies, enabling the screen display area to dynamically adjust between extended and retracted states, transforming a static structure into a dynamic one that adapts to different user needs
Solution Approach 2:
The support frame is segmented into multiple independent support bodies (first support body and second support body) that can move relative to each other. This segmentation allows the screen display area to be adjusted in a controlled manner, with each support body contributing to the overall adjustability while maintaining structural integrity
2Adaptability or versatility
If the screen display area is adjustable, then user needs for different tasks are met, but the device structure becomes complex
Solution Approach 1:
The driver serves multiple functions: it drives the second support body to move relative to the first support body, and simultaneously drives the screen body connecting mechanism to move through the transmitting mechanism. This multi-functionality reduces the need for separate driving mechanisms, thereby adjusting the screen display area while controlling structural complexity
Solution Approach 2:
A transmitting mechanism is introduced as an intermediary component that transmits the driving force from the driver to both the second support body and the screen body connecting mechanism. This intermediary mechanism enables coordinated movement of multiple components through a single driver, simplifying the overall control structure while achieving adjustable screen display area

AI summary
A support structural member and a display device. The support structural member includes: a support frame, having a screen body support surface, in which the support frame includes a first support body and a second support body, the first support body and the second support body are connected to each other, and the second support body is enabled to move relative to the first support body in a first direction; a power unit, including a transmitting mechanism, a screen body connecting mechanism and a driver, in which the driver drives the second support body to move relative to the first support body in the first direction through the transmitting mechanism, and the driver drives the screen body connecting mechanism to move through the transmitting mechanism, so that the second support body and the screen body connecting mechanism move in the same direction in the first direction.
