Wedge Adjustment Head for Support Arm Levelling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support arm systems face issues with wear and lateral tilting under high loads due to punctiform adjustment mechanisms, and difficulty in adjusting screws, especially in confined spaces like wall hinges.
Innovation Solution
A wedge-shaped adjustment head interacting with the support arm and hinge part, allowing for distributed load adjustment via a convex pressure surface and adjustable screw channel, enabling easy operation and secure levelling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If adjustment screws act on the hinge in a punctiform manner, then the structure remains simple, but the support arm experiences wear and lateral tilting under high loads
Solution Approach 1:
The adjustment mechanism transitions from a punctiform (point-based) contact to a distributed contact through a wedge-shaped adjustment head. The wedge surface distributes the adjustment force across a larger area of the hinge part, reducing localized wear and improving stability under high loads while maintaining structural simplicity
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 solution provides secure, reliable, and easy levelling of support arms under load, distributing weight over a larger area and facilitating adjustments from a convenient working position, reducing wear and tilting issues.
Implementation Method 1
a wedge surface (9.1) of the adjustment head interacts with a slide incline (12) of the hinge part (4)

AI summary
Adjustment device for a support arm system, support arm system includes a support arm for holding an object, a hinge part having a receiving portion for securing the support arm, and the hinge part being rotatably mounted on a hinge retainer. Support arm is securable with an end face to the hinge part, and a deployment angle of the support arm being adjustable using adjustment device which is formed from a wedge-shaped adjustment head that interacts with a slide incline of the hinge part and the end face of the support arm. Adjustment head includes a wedge surface and a pressure surface that lies opposite wedge surface, and adjustment head is adjustable such that the wedge surface slides along on the slide incline and pressure surface therefore pressing against end face of the support arm such that the deployment angle of the support arm can be adjusted.
