Threaded Support Arm for Precise Vertical Monitor Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support arms for objects like monitors and televisions are difficult to vertically adjust without damaging the object, and often require the use of springs or cables, which detract from aesthetics and increase costs.
Innovation Solution
A support apparatus with a threaded support member and a movable collar that allows for vertical adjustment of arm assemblies without the need for springs or cables, utilizing a friction adjustment mechanism to secure the object's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If circumferential recesses are used for vertical positioning, then the support arm can be positioned at discrete locations, but the adjustment becomes difficult and time-consuming requiring removal of supported objects
Solution Approach 1:
The patent replaces the mechanical system of discrete circumferential recesses with a continuous threaded mechanism. The thread allows the collar to be smoothly adjusted to any vertical position along the support post, eliminating the need for discrete positioning steps and the associated difficulty of removing and repositioning heavy supported objects.
Solution Approach 2:
The invention changes the parameter of vertical positioning from discrete circumferential locations to continuous linear positions along the thread. This parameter transformation enables fine-tuned vertical adjustment while maintaining precise positioning capability, resolving the contradiction between positioning precision and adjustment ease.
2Ease of operation
If springs or gas springs are used to support the object, then positioning adjustment is permitted, but the aesthetic effect is deteriorated and fabrication cost increases
Solution Approach 1:
The patent extracts and eliminates the need for springs or gas springs from the support arm system. The threaded support post and movable collar mechanism provide structural support and positioning adjustment capability without requiring visible spring elements, thereby maintaining aesthetic appearance while preserving adjustment functionality.
Solution Approach 2:
The invention replaces expensive aesthetic-detracting components (springs, gas springs, cables) with a simple, cost-effective threaded mechanical system. The thread and collar mechanism achieves the same positioning adjustment function at lower fabrication cost without compromising appearance.
3Reliability
If cables are used to support the object, then positioning is maintained, but the aesthetic effect is deteriorated and fabrication cost increases
Solution Approach 1:
The patent removes cables from the support system entirely. The threaded support post and collar mechanism provide inherent structural support and positioning maintenance without requiring external cables, eliminating the aesthetic deterioration and fabrication cost associated with cable installation.

AI summary
A support apparatus includes a support member having at least one thread, a collar attached to the support member that is moveable along the one or more threads of the support member and at least one arm assembly attached to or positioned on the collar. The one or more threads may include a ridge formed on the support member or a groove formed in the support member. The one or more arm assemblies are configured to hold an object such as, for example, a monitor, copy holder, liquid crystal display or light fixture.
