Dual Screen Extender Frame Structure With Sliding Clamps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screen extenders for laptops suffer from poor usability due to difficult disassembly and instability, as they often rely on magnets or 3M adhesive for attachment.
Innovation Solution
A frame structure for a dual screen extender featuring a support body with slidably arranged clamping portions, sliding rods, and elastic tensioning pieces, allowing for easy assembly and disassembly, and providing stability through elastic force and multiple force points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnets or 3M adhesive are used to connect the frame to the display, then the connection is stable, but the frame cannot be removed easily
Solution Approach 1:
The frame is divided into a connecting frame and a support body that can be separated. The connecting frame attaches to the display while the support body with screen can be detached, allowing easy removal while maintaining stable connection during use
Solution Approach 2:
The frame transitions from a static permanent connection (magnets/adhesive) to a dynamic removable connection. The sliding rod mechanism allows the support body to move between attached and detached states, providing both stability during use and ease of removal
2Device complexity
If a single force point is used for mounting, then the structure is simple, but the support body is unstable
Solution Approach 1:
The mounting structure is segmented into multiple independent clamping portions (first and second clamping portions) that clamp the display at different locations. This distributes the mounting force across multiple points, enhancing stability while keeping each individual clamping mechanism relatively simple
Solution Approach 2:
Multiple clamping portions are combined to work together, creating a stable mounting system. The first and second clamping portions cooperate to secure the display firmly, providing stability through distributed force points
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The frame structure enables convenient assembly and disassembly, enhances stability and balance, and extends the service life by maintaining clamping functionality even with mechanical failures on one side.
Implementation Method 1
An elastic tensioning piece is arranged in each of the sliding channels. Each elastic tensioning piece is configured to provide elastic tensioning force for a corresponding sliding rod.

AI summary
A frame structure of a dual screen extender includes a support body. Two clamping portions are slidably arranged on two sides of the support body. Sliding rods are arranged on the clamping portions. Sliding channels are formed on the support body. The sliding channels are matched with the sliding rods. An elastic tensioning piece is arranged in each of the sliding channels. Each elastic tensioning piece is configured to provide elastic tensioning force for a corresponding sliding rod. At least one of the two clamping portions is provided with a screen support. The screen support is rotatable. The screen support is stacked on the support body when the screen support is rotated to be fully folded. A state maintaining assembly is arranged on each of the clamping portions. Each state maintaining assembly is configured to position the screen support before and after rotation of the screen support.
