Monitor Stand Friction and Spring Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a monitor stand that can efficiently and conveniently adjust the angle of a monitor to user preferences without unnecessary movement, addressing the requirement for stability and adjustability in both residential and commercial settings, including integration with automation systems.
Innovation Solution
A monitor stand with trapezoidal shaped cubic protrusions and a low friction insert system, combined with spring retention assemblies, allows the monitor to be rotated between specific angular placements while maintaining stability through a constant rotational spring force and frictional interface, preventing unwanted movement due to gravity or user action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a monitor stand allows rotation between angular placements for user adjustment, then ease of operation is improved, but stability deteriorates due to unwanted movement from gravity
Solution Approach 1:
The spring retention assembly applies a preliminary counteracting force (spring force) to oppose the gravitational force that causes unwanted rotation. This preliminary anti-action prevents the monitor from drifting to extreme angles by continuously applying a restoring force toward the neutral position, thus maintaining stability while still allowing user-initiated adjustment.
Solution Approach 2:
The system changes the friction parameter dynamically through the interaction between the low friction insert and the carrier. The low friction insert reduces friction during user-adjusted rotation to enable smooth movement, while the spring force increases with displacement to provide stronger resistance against gravity-driven unwanted movement, effectively changing the net restraining parameter based on operational needs.
2Ease of operation
If a low friction insert is used to enable smooth rotation, then ease of operation is improved, but stability worsens due to insufficient resistance against gravitational movement
Solution Approach 1:
The invention merges two opposing friction characteristics: a low friction insert for smooth rotation during user adjustment, and a higher friction interface (between the carrier and base enclosure) that provides gravitational resistance. This combination allows the system to achieve both smooth operability during intentional adjustment and adequate stability against unwanted gravitational movement.
Solution Approach 2:
The spring retention assembly provides preliminary anti-action by applying spring force that counteracts gravitational force before unwanted rotation can occur. This spring force works in conjunction with the frictional interfaces to prevent the monitor from drifting, while the low friction insert ensures that user-initiated rotation remains smooth and requires minimal effort.
3Stability of the object's composition
If spring retention assemblies provide constant rotational spring force to counteract gravity, then stability is improved, but device complexity increases
Solution Approach 1:
The spring retention assembly is designed as a self-regulating mechanism where the spring force automatically adjusts based on the angular displacement. As the monitor rotates away from the neutral position, the spring force increases proportionally, providing self-correcting stability without requiring external control systems or complex mechanisms. The system serves itself by using the displacement to generate the appropriate counteracting force.

AI summary
An adjustable monitor stand that can hold a monitor includes a carrier, a base, and a low friction insert. First and second channel insertion portions extend from a curved lower surface of the low friction insert. Each has outer walls to be received by and fixedly engage with first and second base channels formed in a curved upper surface of the base, respectively, to prevent movement of the low friction insert with respect to the base. The first and second channel insertion portions each have inner walls to receive first and second protrusions extending from a curved lower surface of the carrier, respectively, and permit the carrier to be moved about a non-vertical axis as the first and second protrusions slide along the inner walls. The first and second protrusions of the carrier also form a frictional engagement with the inner walls of the first and second channel insertion portions.
