Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extension arms are not well-suited for sleek, compact designs, as reducing component size can compromise performance, particularly in supporting larger devices and may lead to loose connections during adjustments, posing safety hazards.
Innovation Solution
The design incorporates an adjustable support apparatus with angled clevis assemblies and tapered channels, allowing for a smaller gas spring to support heavier loads while preventing loosening between components through an interlocking washer and shaft configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If component sizes are reduced to achieve compact design, then device size is reduced, but load support capability deteriorates
Solution Approach 1:
The patent employs curved or tapered channel shapes instead of straight rigid channels. The tapered channels gradually change in cross-sectional area, providing structural reinforcement where needed while maintaining overall compactness. This curvature and gradual transition allow the structure to better distribute loads without requiring larger overall dimensions.
Solution Approach 2:
The patent changes geometric parameters of the channel structure, specifically implementing tapered sections with varying cross-sectional areas along the channel length. This parameter variation allows the structure to be optimized for both strength and compactness, with thicker sections providing load support and thinner sections reducing overall volume.
2Volume of moving object
If component sizes are reduced to achieve compact design, then device size is reduced, but connection reliability deteriorates
Solution Approach 1:
The patent incorporates anti-loosening mechanisms that are pre-installed or pre-configured in the connection elements. These mechanisms proactively prevent loosening before it occurs, rather than reacting to loosening after it happens. This preliminary protective action ensures connection reliability is maintained throughout the device's operation.
Solution Approach 2:
The patent converts the potential harmful effect of rotational movement (which could cause loosening) into a beneficial feature by incorporating specialized connection elements that are designed to maintain secure connections during rotation. The rotational movement is accommodated and controlled rather than resisted, preventing loosening while enabling the desired motion.
3Volume of moving object
If smaller gas spring is used to achieve compact design, then device size is reduced, but leverage and load support capability deteriorate
Solution Approach 1:
The curved or tapered channel geometry provides mechanical advantage by optimizing the force transmission path. The gradual change in channel cross-section creates more effective leverage points and distributes the gas spring force more efficiently, allowing a smaller gas spring to achieve the same load support capability as a larger spring would provide in a straight channel configuration.
Solution Approach 2:
By changing the geometric parameters of the channel (taper ratio, curvature radius, section area distribution), the patent optimizes the mechanical leverage system. These parameter changes allow the smaller gas spring to generate sufficient force through improved force multiplication and distribution along the tapered channel structure.

Function Achieved in This Case
This design enables a more compact and cost-effective extension arm that supports heavier loads with improved flexibility and safety by using a smaller gas spring and preventing loose connections, while maintaining performance and stability.
Implementation Method 1
a spring mechanism (e.g., a gas spring) disposed within the first endcap and operably connected to the first channel
Implementation Method 2
a rod threaded through the clevis and the first endcap, with the rod positioned at the predetermined angle relative to the axis of the first endcap

AI summary
The present invention provides an extension arm apparatus with angled clevis operation to provide enhanced mechanical leverage. The clevis adjusts along a path angled relative to an axis of the device, which significantly boosts performance and can reduce the size of the apparatus. Upper and lower channels of the device taper from a first width to a second width, providing a sleek and functional apparatus that can be used with heavy monitors, displays or other user equipment. When a forearm extension attached to an endcap of the apparatus, an interlocking washer and shaft configuration prevents the forearm extension-endcap connection from loosening during operation.
