Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display support arm assemblies lack adjustable force mechanisms and effective rotational resistance, limiting user flexibility in positioning and securing displays.
Innovation Solution
The display support arm assembly incorporates a gas strut for vertical adjustment, torque elements for adjustable friction, and a washer-gasket system to resist unintended rotational movement, providing a customizable and stable mounting solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gas strut is used to provide force throughout the vertical adjustment range, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent employs a gas strut as a pneumatic mechanism to provide lifting force and support the display at various vertical positions. The gas strut extends between the proximal and distal housings, utilizing gas pressure to counteract the weight of the display and enable smooth vertical adjustment without requiring manual effort to overcome gravity throughout the adjustment range.
2Stability of the object's composition
If torque elements are added to provide adjustable friction force, then the stability of the display position is improved, but the device complexity increases
Solution Approach 1:
The torque elements are designed to be adjustable, allowing the friction force to be modified based on the display weight and desired positioning stability. This dynamic adjustment capability enables the system to adapt to different loading conditions and stability requirements, optimizing the balance between ease of adjustment and position holding capability.
3Reliability
If the washer-gasket system is implemented to resist rotational movement, then the reliability of the mounting is improved, but the device complexity increases
Solution Approach 1:
The rotational resistance mechanism is segmented into distinct functional components: washers that provide structural support and rotation resistance, and gaskets that fill gaps and prevent unintended rotation. This segmentation allows each component to be optimized for its specific function while collectively providing reliable rotational restraint for the mounted display.
