Monitor Support Arm With Single-Joint Plane-Stable Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitor support systems require complex and expensive mechanisms with multiple pivots for three-dimensional adjustment, leading to bulkiness and an unsightly appearance due to additional visible links or deep casings.
Innovation Solution
A single mechanism allowing full range adjustment in three orthogonal directions using a combination of a curved support arm and a motion joint with a sliding mechanism, which maintains the monitor in the same plane during up and down movement, reducing the need for additional visible links and minimizing bulkiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate and distinct pivot arrangements are used for three-dimensional adjustment, then the monitor can achieve full range adjustment in three orthogonal directions, but the device becomes more complicated, expensive, and unsightly with more moving parts
Solution Approach 1:
The patent combines two separate pivot arrangements into a single integrated pivot mechanism. The arcuate connector incorporates both the horizontal pivoting function and the vertical adjustment function within one unified structure, eliminating the need for a second separate vertical pivot. This merging reduces the number of moving parts while maintaining full three-dimensional adjustment capability.
Solution Approach 2:
The single pivot mechanism is designed to perform multiple functions: it enables both horizontal rotation of the monitor and vertical adjustment of the monitor's position. The arcuate connector's geometry allows it to guide the monitor through complex three-dimensional motion paths while relying on a single pivot point, making the pivot universally functional for multiple adjustment directions.
2Stability of the object's composition
If a four-bar linkage or parallelogram arrangement is used to maintain the monitor in the same plane during movement, then the monitor remains stable, but additional visible links or a deep casing are required which are bulky and unsightly
Solution Approach 1:
The patent extracts the plane-maintaining function from the visible four-bar linkage structure and integrates it into the internal geometry of the arcuate connector. The connector's curved path inherently guides the monitor to maintain a consistent plane during movement, eliminating the need for external visible links or a deep casing to house such mechanisms.
Solution Approach 2:
The patent solves the plane stability problem by moving the mechanism into a different dimensional space. The arcuate connector uses a three-dimensional curved path that naturally constrains the monitor's movement to maintain its plane, rather than using traditional two-dimensional parallel links that would be visible. The stability is achieved through the spatial geometry of the arcuate path rather than through visible mechanical linkages.

AI summary
A support arm system for a load such as a display device. The system includes a support arm (4) rotatable at its proximal end about a mid-joint axis X", monitor supporting head (5) at the distal end of the support arm (4) has an internal slider element and compression spring, and an arrangement of links and pivots which create a torque to oppose the torque created by a load on the head (5) and keep a monitor plate (6) in the same viewing plane relative to the vertical as the arm (4) moves through its range of movement.
