Compact Extension Arm with Angled Clevis for Heavy Loads
Here’s PatSnap Eureka !
Summary
Problems
Existing extension arms are not well-suited for sleek, compact designs, as reducing component sizes can lead to performance issues, such as inability to support larger devices and loose connections due to inadequate engineering, which can be hazardous.
Innovation solutions
The design incorporates an adjustable support apparatus with angled clevis assemblies and tapered channels, allowing for a smaller gas spring that provides enhanced leverage and load support, along with an anti-loosening mechanism to prevent component separation during rotation.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If component size is reduced to achieve compact design, then device compactness is improved, but load support capability deteriorates
Why choose this principle:
The patent applies parameter changes by modifying the geometric configuration of the clevis assembly (angling it relative to the endcap axis) and the channel structure (tapered design). These parameter changes allow a smaller gas spring to generate sufficient support force for heavier loads through optimized mechanical leverage and force distribution, resolving the contradiction between compact size and load support capability.
Principle concept:
If component size is reduced to achieve compact design, then device compactness is improved, but connection stability deteriorates
Why choose this principle:
The patent employs composite structural design by combining multiple components (clevis, endcap, channel, fasteners) with different geometric properties into an integrated assembly. The tapered channel and angled clevis work together as a composite structure that maintains connection stability despite reduced overall size, preventing loosening through interlocking geometry and distributed stress patterns.

Abstract
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.
