Adjustable Display Mount With Gas-Spring Force Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display screen mounts fail to accommodate viewers in various positions and display screens of differing sizes, weights, and interface configurations, particularly when mounted above a fireplace, leading to discomfort and image quality degradation due to suboptimal viewing angles and increased difficulty in adjusting heavier screens.
Innovation Solution
An adjustable mount with a bracket anchored to a vertical surface, featuring an elongated upper link, a faceplate with a rail, and gas springs, allowing for height adjustment and force balancing, along with pivotable and tiltable mechanisms to optimize viewing angles and ease of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display screen is mounted high on the wall above a fireplace, then the standing viewer has an unobstructed view, but the seated viewer experiences discomfort due to the screen being well above eye level
Solution Approach 1:
The mount incorporates a height-adjustable mechanism with links and joints that enable the display screen to be dynamically repositioned between a high stowed position (above fireplace) and a lower viewing position, allowing adaptation to different viewer positions and situations
Solution Approach 2:
The mount serves multiple functions: it securely anchors the display in a high decorative position above the fireplace while also enabling temporary lowering for comfortable viewing, thus accommodating both aesthetic requirements and ergonomic needs in a single system
2Ease of operation
If the display screen is positioned far from the wall to avoid contacting the mantel, then the screen is accessible for viewing, but the screen may contact the mantel when lowered
Solution Approach 1:
The mount uses a four-bar linkage mechanism with movable links that dynamically adjust the horizontal clearance between the screen and wall/mantel based on the screen's vertical position, maintaining safe clearance at all times while enabling accessible viewing
3Manufacturing precision
If the display screen is tilted or pivoted to optimize viewing angle, then image quality improves, but the mount structure becomes more complex
Solution Approach 1:
The mount incorporates pivot joints and tilt mechanisms that enable the display screen to be dynamically angled and oriented, allowing optimization of viewing geometry and image quality while maintaining a relatively compact structural design through efficient use of linkage geometry
4Ease of operation
If the display screen is lowered for viewing, then viewing comfort improves, but the screen moves farther from the wall requiring more space
Solution Approach 1:
The mount employs a linkage mechanism that dynamically coordinates horizontal and vertical movement, allowing the screen to lower while maintaining controlled clearance from the wall, thus achieving viewing comfort without excessive protrusion into the room space
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adjustable mount ensures peak image quality and reduces user effort by accommodating different screen sizes and weights, allowing for comfortable viewing from various angles while securely anchoring to diverse wall constructions.
Implementation Method 1
one gas spring pivotally connected to the bracket below the upper link and above each bar of the pair of bars. The gas spring is pivotally connected to the body

AI summary
An adjustable mount including a bracket adapted for anchoring the bracket to a surface and an elongated link pivotally connected to the bracket. A faceplate adapted for connecting to the display screen is pivotally connected to the link. The faceplate has a rail below the link. A body is slidably mounted on the rail, and a clamp alternatively holds the body at a selected position on the rail. The mount includes a pair of elongated bars. Each bar is pivotally connected to the bracket below the link and pivotally connected to the faceplate below the link. The mount has one gas spring pivotally connected to the bracket below the link and above each bar and pivotally connected to the body. The faceplate is moveable to raise and lower the display screen. A force required to move the faceplate changes depending upon the selected position of the body on the rail.
