Multi-display Stand with Position-Limiting Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-display stands are inconvenient to use with modern operating systems that support multiple displays, as they require frequent adjustments in angle and position, leading to instability and potential toppling when supporting arms are at different heights.
Innovation Solution
A multi-display stand design featuring radially rotatable supporting arms with position-limiting members, including tenons and position-limiting walls, that restrict the rotation angle to prevent imbalance and toppling, allowing for adjustable display angles and positions without compromising stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the supporting arms are made radially rotatable to allow easy adjustment of display angles, then the ease of operation is improved, but the stability of the stand deteriorates when arms are at different heights
Solution Approach 1:
The position-limiting walls are pre-positioned on the standing rod to define safe rotation angle ranges before the user operates the supporting arms. This preliminary structural arrangement prevents the stand from toppling by limiting the maximum rotation angle, while still allowing sufficient adjustment range for practical use.
Solution Approach 2:
The position-limiting member acts as an intermediary between the supporting arms and the standing rod. It includes position-limiting walls that contact the supporting arms to restrict their rotation, thereby mediating between the need for adjustability and the need for stability.
2Adaptability or versatility
If the supporting arms can rotate freely to accommodate different user positions, then the adaptability is improved, but the stand may topple over when arms are excessively rotated
Solution Approach 1:
The position-limiting walls are pre-configured on the standing rod to establish safe rotation boundaries before use. This ensures that regardless of how the user operates the arms, the rotation will be automatically limited to a safe range that maintains stand stability.
Solution Approach 2:
The position-limiting walls provide mechanical feedback to the user during operation. When the supporting arm approaches the maximum safe rotation angle, the position-limiting wall contacts the arm, providing tactile feedback that prevents further rotation and alerts the user to the limit.

AI summary
A multi-display stand configured to support a plurality of displays is provided. The multi-display stand includes a standing rod, a plurality of supporting arms, and a position-limiting member. The standing rod extends along a central axis. The supporting arms are disposed on the standing rod. Each of the supporting arms supports one of the displays. The position-limiting member is disposed between the standing rod and each of the supporting arms and includes at least one first position-limiting wall, at least one second position-limiting wall, and at least one tenon. Each of the supporting arms is radially rotatable about the central axis with respect to the standing rod between a first position and a second position. When the supporting arm is at the first position, the tenon abuts against the first position-limiting wall. When the supporting arm is at the second position, the tenon abuts against the second position-limiting wall.
