Angle Adjustment Mechanism With Elastic Friction Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing angle adjustment mechanisms in electronic apparatuses, such as those using friction units, face instability due to the repulsive force transmitted to the rotation shaft, leading to potential deformation and quality issues.
Innovation Solution
An angle adjustment mechanism comprising a base member, a support member, a mount member with a rotation shaft, and a suppression member formed of an elastic material that suppresses up-and-down movement by frictional force, where the support member slides through a hole in the suppression member, allowing for stable angle adjustment without deforming surrounding components.

1Reliability
If a friction unit is used to maintain the angle of the display unit, then the angle can be held stable, but the repulsive force deforms the rotation shaft and affects surrounding components
Solution Approach 1:
A cushioning member (elastic body) is introduced as an intermediary between the friction unit and the rotation shaft. The friction unit presses against the cushioning member rather than directly against the rotation shaft, absorbing the repulsive force through elastic deformation. This mediator protects the rotation shaft from deformation while maintaining the friction-based angle holding function.
Solution Approach 2:
The cushioning member is pre-installed in the accommodation space around the rotation shaft before the friction unit operates. This beforehand cushioning arrangement ensures that when the friction unit generates repulsive force during angle adjustment, the cushioning member is already in position to absorb the force, preventing direct transmission to the rotation shaft and avoiding deformation before it occurs.

If a torque hinge is used for angle adjustment, then stable operation is achieved, but cost and weight increase
Solution Approach 1:
The angle adjustment mechanism is segmented into separate functional components: a friction unit for generating holding force, a cushioning member for absorbing repulsive force, and a simple rotation shaft for movement. This segmentation replaces the integrated torque hinge mechanism with distributed simple components that collectively achieve the same function with reduced weight and cost.
Solution Approach 2:
The invention replaces the expensive torque hinge with simpler, cheaper components such as a basic rotation shaft and an elastic cushioning member. These simpler components achieve the required operational stability through their combined functions of friction-based holding and elastic force absorption, significantly reducing manufacturing cost and weight compared to a torque hinge.
