Swivel Torque Hinge Support Arm Structure for Stable Rotational Torque
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing supporting mechanisms for devices like monitors experience unstable rotational torque and durability issues due to offset loads on friction torque generating mechanisms, leading to variations in stopping states and increased risk of hanging down, especially as the supported devices grow in size.
Innovation Solution
A supporting mechanism that uses a swivel torque hinge with elastic members like friction washers and spring washers, where the hinge shaft is pivotally supported on an attaching hole, and a fixing guide member is attached to the bracket, jointly fastened with screws, and shaft bearing members are mounted on the supporting arms and guide member to reduce offset loads and enhance durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a swivel torque hinge with friction torque generating mechanism is used to support equipment, then the equipment can be held mobile in horizontal and vertical directions, but offset load shifts toward one side causing unstable rotational torque and variations in stopping state
Solution Approach 1:
The supporting arm is divided into multiple sections (first supporting arm and second supporting arm) connected by the swivel torque hinge. This segmentation allows the hinge to be positioned at an intermediate point rather than at the end, distributing the load more evenly and reducing offset load on the friction torque generating mechanism while maintaining mobility.
2Force
If offset load is applied to axial urging members such as spring washers on a swivel torque hinge, then the hinge can provide friction torque, but aging variations in friction torque occur and durability deteriorates
Solution Approach 1:
The bracket is designed with a specific structure that counterbalances the offset load through its geometric configuration. The bracket extends in a direction substantially perpendicular to the supporting arm and has a width that creates a counterbalancing moment, reducing the net offset load on the spring washers and friction torque generating mechanism, thereby improving durability.
3Volume of moving object
If the supported device is enlarged, then the device can provide more functionality, but the occurrence of hanging down of the supporting device increases
Solution Approach 1:
The bracket extends in a direction substantially perpendicular to the supporting arm (a different dimension), creating a wider support base. This dimensional change increases the moment arm for counterbalancing the hanging down force, providing better stability for larger supported devices without increasing the vertical height of the supporting mechanism.
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
This configuration stabilizes rotation torque, improves durability of the friction torque generating mechanism, and reduces the likelihood of hanging down by attenuating offset loads, resulting in smoother arm movement and enhanced durability.
Implementation Method 1
a swivel torque hinge (30) which comprises a friction torque generating mechanism using elastic members such as friction washers (36) and spring washers (33)
Implementation Method 2

AI summary
A supporting mechanism for a supporting device that supports supporting arms to which a pressing down load is applied on one side relative to an attaching element such that the former are mobile at least in a horizontal direction, as well as a supporting device having a supporting mechanism is disclosed. The solution is sought by using a swivel torque hinge having a friction torque generating mechanism using elastic members such as friction washers and spring washers for the supporting mechanism by pivotally supporting a shaft upper portion of a hinge shaft of the swivel torque hinge on an attaching hole portion provided on the supporting arms by providing a bracket supporting the supporting arms on the hinge shaft via the friction torque generating mechanism.
