Expanded Screen with Multi-Axis Rotating Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing expanded screens for terminal devices have limited flexibility due to hinge mechanisms that allow only one-directional rotation, and they are often unremovable, making them inconvenient to carry when not in use.
Innovation Solution
The expanded screen incorporates a first and second rotating assembly that allows the fixed device to rotate in multiple directions, enabling multidimensional displaying and easy adjustment of the display device's angle, along with a magnetic suction mechanism for quick and easy mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hinge method is used to connect the fixed device to the display device, then the structure is simple, but the rotation is limited to one direction only, reducing flexibility of use
Solution Approach 1:
The patent employs nested rotating assemblies where the first rotating assembly is rotatably connected to the display device, and the second rotating assembly is rotatably connected to the first rotating assembly. This nested configuration enables multi-directional rotation while maintaining a compact integrated structure, resolving the contradiction between flexibility and structural simplicity.
Solution Approach 2:
The patent transforms the static hinge connection into a dynamic multi-rotating system. The first rotating assembly allows rotation around a first axial direction, and the second rotating assembly allows rotation around a second axial direction, creating a dynamically adjustable display configuration that adapts to various user needs.
2Ease of operation
If the expanded screen is made unremovable, then the connection is stable, but the expanded screen cannot be carried when not in use, reducing convenience
Solution Approach 1:
The magnetic suction connection provides a dynamic balance between stability and removability. The magnetic force maintains a stable connection during use, yet allows easy separation when needed, enabling the expanded screen to be both reliably connected and conveniently carried when not in use.
3Ease of manufacture
If a magnetic suction mechanism is used to fix the fixed device, then the mounting is quick and easy, but the holding force may be insufficient for heavy displays
Solution Approach 1:
The patent merges the magnetic suction mechanism with the rotating assembly structure. The magnetic suction provides quick mounting capability, while the integrated rotating assembly ensures stable mechanical connection and proper positioning, combining the advantages of both magnetic attraction and mechanical structuring to achieve both ease of mounting and sufficient holding force.

AI summary
The present disclosure provides an expanded screen. The expanded screen includes a display device, a fixed device, a first rotating assembly and a second rotating assembly. The fixed device is configured to be fixed on a display. The first rotating assembly is rotatably connected to the display device. One end of the second rotating assembly is rotatably connected to the first rotating assembly, and the other end of the second rotating assembly is connected to the fixed device. The fixed device rotates through the first rotating assembly around a first axial direction. The fixed device rotates through the second rotating assembly around a second axial direction. The first axial direction is a width extending direction of the display device and the second axial direction is a direction perpendicular to a display surface of the display.
