Dual Display Device Flexible Screen Sliding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dual display devices lack the ability to enhance display diversity effectively, as they do not provide a flexible solution for varying display needs.
Innovation Solution
A dual display device comprising a housing, a first display screen, a flexible display screen, and a rotating assembly, where the flexible screen can be slid into and out of the housing using a U-shaped slide rail and limiting mechanisms, allowing for parallel sliding and preventing complete insertion or ejection, enabling versatile display configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display screen is fixed permanently in the housing, then the display configuration is stable, but the display diversity is limited
Solution Approach 1:
The flexible display screen is designed to be movable rather than fixed, allowing it to slide between the containing chamber and the exterior of the housing. This dynamic configuration enables the display to transition between different positions and states, providing multiple display modes (single screen, dual screen, folded configurations) while maintaining structural stability through guided motion paths and limiting mechanisms.
Solution Approach 2:
The display system is segmented into a fixed first display screen and a movable flexible display screen. This segmentation allows the flexible portion to be independently positioned and configured, enabling diverse display arrangements while the fixed portion provides stable structural support and housing integration.
2Adaptability or versatility
If the flexible display screen can slide freely in and out, then the display versatility is improved, but the risk of complete ejection or damage increases
Solution Approach 1:
Limiting mechanisms are pre-configured within the housing structure to prevent the flexible display screen from sliding completely out of the containing chamber or being fully ejected from the housing. These mechanisms establish boundaries before any damage can occur, ensuring the display remains within safe operational ranges while still allowing substantial movement freedom.
Solution Approach 2:
The U-shaped slide rail acts as an intermediary component between the flexible display screen and the housing. It provides guided motion that allows the display to slide in and out freely while constraining it to a controlled path, preventing uncontrolled ejection and ensuring reliable operation throughout the full range of motion.
3Adaptability or versatility
If a complex mechanism is used to enable flexible screen movement, then the display versatility is enhanced, but the device complexity increases
Solution Approach 1:
The flexible display screen utilizes its own flexibility and the natural sliding motion along the U-shaped rail to achieve movement between configurations. The system requires minimal additional actuation mechanisms, as the display can be manually positioned or lightly guided into place, reducing the need for complex motors, sensors, or control systems.
Solution Approach 2:
The U-shaped slide rail serves multiple functions simultaneously: it guides the motion of the flexible display screen, provides structural support, defines the movement boundaries through its geometry, and works in conjunction with the limiting mechanisms. This multi-functionality reduces the need for separate components for each function, simplifying the overall device structure.

AI summary
A dual display device is provided, which includes a housing, a first display screen, a flexible display screen, and a rotating assembly. The housing includes a plurality of vertical walls and a bottom wall, the plurality of vertical walls include a second vertical wall. The first display screen is mounted in the housing at a first predetermined distance from the bottom wall, and a first edge of the first display screen is spaced apart from the second vertical wall by a second predetermined distance. The rotating assembly is rotatably disposed in an opening in an axial direction of the rotating assembly.
