Articulating Arm Assembly With Reconfigurable Rotation Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing workstations with articulating arm assemblies do not efficiently transition between stowed and extended orientations, limiting user flexibility and ergonomic adjustment.
Innovation Solution
An articulating arm assembly with a reconfigurable rotation stop mechanism allows the workstation to easily switch between stowed and extended positions, incorporating a rotation stop assembly to control the direction of arm rotation and enhance ergonomic positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the arm assembly is designed to allow frequent adjustments between stowed and extended orientations, then user satisfaction and ergonomic positioning are improved, but the device complexity increases due to the need for reconfigurable rotation stop mechanisms
Solution Approach 1:
The rotation stop mechanism is designed to be reconfigurable, allowing the arm assembly to dynamically adjust between different operational modes (stowed and extended orientations). The rotation stop can be repositioned to different angular positions, enabling the system to adapt to different user needs and orientations without requiring a completely different mechanism for each position.
Solution Approach 2:
The arm assembly is divided into multiple segments (first arm and second arm) that can rotate independently relative to each other. This segmentation allows each segment to be controlled separately, with the rotation stop mechanism specifically managing the relative rotation between segments, thereby simplifying the overall control while maintaining flexibility.
2Manufacturing precision
If the rotation stop assembly is designed to control the direction of arm rotation precisely, then ergonomic positioning is enhanced, but the device complexity increases
Solution Approach 1:
The rotation stop assembly acts as an intermediary mechanism between the motor control system and the arm segments. It provides a mechanical means to precisely control and limit the rotation direction and range, translating electrical control signals into precise mechanical positioning without requiring complex control algorithms or additional sensors.
Solution Approach 2:
The rotation stop mechanism allows for easy adjustment of rotation parameters (angular range, stop positions) by simply repositioning the stop components. This parameter adjustability is achieved through simple mechanical adjustments rather than complex electronic controls, maintaining precision while minimizing device complexity.

AI summary
A workstation holding electronic devices, e.g., a display, keyboard, or the like, can be mounted on a structure, e.g., a wall, using an articulating arm assembly including one or more arms. The one or more arms can be rotatingly coupled to the structure. The one or more arms can be configured to translate the workstation between a contracted orientation and extended orientation. The arm assembly can include a configurable rotation stop assembly. The rotation stop assembly can be configured to limit a rotation angle of the one or more arms in a range between 0 degrees in the contracted orientation and less than 180 degrees in the extended orientation.
