Rotating Module Friction Adjustment for Display Mounts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotating modules are designed for specific display weights, limiting their ability to support displays with varying weights and adjust to any swivel or tilt angle smoothly, as the interference between the rotary unit and shaft must be predetermined.
Innovation Solution
A rotating module using a rubbing element with an arcuate arm and a mandrel, where the friction is adjusted by altering the number, thickness, or interference level between the rubbing element and the mandrel, allowing displays to pivot and swivel at any angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the interference level between the rotary unit and shaft is designed based on predetermined display weight, then the supporting device can hold the display with predetermined weight, but it cannot smoothly support displays with different weights or allow adjustment to any swivel angle
Solution Approach 1:
The patent applies dynamics by making the interference level adjustable rather than fixed. The arcuate arm can be repositioned along the shaft to change the interference level between the rotary unit and shaft, allowing the system to adapt to different display weights and swivel requirements dynamically
Solution Approach 2:
The patent changes the parameter of interference level by allowing the arcuate arm to be positioned at different locations along the shaft. This parameter adjustment enables the system to accommodate different display weights and achieve smooth swivel adjustment across various configurations
2Strength
If the interference level is increased to support heavier displays, then the supporting strength is improved, but the ease of adjustment to any angle deteriorates
Solution Approach 1:
The arcuate arm can be dynamically repositioned along the shaft to adjust the interference level. For heavier displays, the arcuate arm is positioned to increase interference and supporting strength; for easier adjustment, it can be repositioned to reduce interference, maintaining a balance between strength and operability
3Ease of operation
If the interference level is decreased for easier adjustment, then the ease of operation is improved, but the supporting strength for heavy displays deteriorates
Solution Approach 1:
The system allows dynamic adjustment of the arcuate arm position along the shaft. When easy adjustment is needed, the arcuate arm is positioned to decrease interference; when supporting heavy displays is required, the arcuate arm is repositioned to increase interference, providing both ease of operation and sufficient strength as needed
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
Enables displays of different weights to be supported and adjusted to any horizontal or vertical view angle, eliminating the need for customization based on weight, with the module's friction being adaptable through adjustments in the rubbing element's configuration.
Implementation Method 1
the pivoting part of the mandrel and the arcuate arm are assembled with interference fit for the display pivotably stopping at any angle

AI summary
A rotating module comprising a mandrel and at least one rubbing element in provided. The at least one rubbing element is sleeved on the mandrel. The diameter of a pivoting space defined by an arcuate arm of the at least one rubbing element is smaller than the diameter of the mandrel so that the at least one rubbing element and the mandrel are assembled with interference fit.
