Display Mount Rotation Stop for Ergonomic Arm Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display mounts lack effective mechanisms to limit and adjust the rotation of electronic displays relative to a structure, compromising workspace ergonomics and user comfort.
Innovation Solution
A display mounting system with a lock collar that includes rotation stops to limit the rotation of an articulating arm assembly, allowing for a limited or free rotation configuration based on user preference, and a slider mechanism to adjust the height and orientation of the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the articulating arm assembly is allowed to rotate freely, then the display can be positioned at various orientations for flexibility, but the workspace ergonomics and user comfort are compromised due to lack of rotation control
Solution Approach 1:
The patent implements rotation stops that allow the articulating arm assembly to be positioned at specific predetermined rotational angles (e.g., 0°, 90°, 180°, 270°). This changes the parameter of rotational freedom from continuous to discrete predetermined positions, providing both flexibility and ergonomic control by limiting rotation to useful orientations only.
Solution Approach 2:
The lock collar mechanism provides dynamic control over the rotation state, allowing the system to transition between locked positions (at predetermined angles) and unlocked free rotation. This dynamic capability enables the display to adapt between fixed ergonomic positions and flexible repositioning as needed.
2Adaptability or versatility
If the lock collar is designed to provide both height adjustment and rotation control, then the device functionality is improved, but the device complexity increases
Solution Approach 1:
The lock collar is designed as a multi-functional component that performs both height adjustment (by sliding along the pole) and rotation control (via engagement with the articulating arm assembly at predetermined angles). This consolidates multiple positioning functions into a single component, improving adaptability while managing complexity through functional integration.
Solution Approach 2:
The patent combines the height adjustment mechanism and rotation stop mechanism into a single integrated lock collar assembly. The lock collar simultaneously provides vertical positioning along the pole and rotational limiting at predetermined angles, merging two separate control functions into one unified component.

AI summary
A display mounting system with an optional rotation stop is described. The display mounting system can include a pole coupled to a support structure and an arm assembly rotatably coupled to the pole. The arm assembly can include an first arm, a second arm, and a pivot adapted to receive an electronic display. A lock collar can be coupled to the pole to maintain the arm assembly at a desired elevation relative to the structure. The lock collar can also include rotation stops to limit a rotation of the arm assembly. A slider built into the arm assembly can be selectively activated to alternate a configuration of the arm assembly between a limited rotation configuration and a free rotation configuration. In the limited rotation configuration, the slider can cooperate with the rotation stops located on the lock collar to limit a rotation of the arm assembly.
