Shock Absorber Adjustment Wheel Push-Twist Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustment wheel arrangements for shock absorbers require separate solutions for adjusting the adjustment tube, fixing adjustment wheels, allowing relative twist, and providing acoustic feedback, resulting in a non-compact design with complex handling and potential for incorrect installation or accidental release.
Innovation Solution
A push-twist connection based on a key-lock principle between the first and second adjustment wheels, allowing relative twist while ensuring axial connection and secure fixation, reducing installation size, and providing user feedback through a spring-loaded ball mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate technical solutions are used for adjusting the adjustment tube, fixing adjustment wheels, allowing relative twist, and providing acoustic feedback, then each function can be fulfilled independently, but the construction becomes non-compact and handling becomes complex
Solution Approach 1:
The patent combines multiple separate technical solutions into a single integrated adjustment wheel arrangement. The first and second adjustment wheels are coupled through a push-twist connection that simultaneously provides torque-proof connection, allows relative twist, and enables acoustic feedback through a spring-loaded ball mechanism, eliminating the need for separate components for each function.
Solution Approach 2:
The adjustment wheel arrangement is designed to perform multiple functions through a unified structure. The push-twist connection serves as a universal interface that handles torque transmission, rotational adjustment, and acoustic feedback generation, making the system multi-functional while maintaining compact dimensions.
2Volume of moving object
If a compact construction is achieved by integrating functions, then installation size is reduced, but ease of manufacture and assembly may be compromised
Solution Approach 1:
The adjustment wheel arrangement is divided into distinct functional segments (first adjustment wheel, second adjustment wheel, spring-loaded ball mechanism) that can be manufactured separately and then assembled through a standardized push-twist connection, maintaining ease of manufacture while achieving compact integration.

AI summary
An adjustment wheel arrangement for a shock absorber with a first adjustment wheel which is configured to connect in a torque-proof fashion to an adjustment tube of a piston rod of the shock absorber, and a second adjustment wheel which is configured to connect in a torque-proof fashion to an adjustment rod extending through the adjustment tube. The first adjustment wheel and the second adjustment wheel can be twisted relative to each other by means of a push-twist connection but are or can be connected by form-fit to each other in the axial direction. The push-twist connection is configured in the manner of a key-lock, such that the first adjustment wheel and the second adjustment wheel can be connected to or separated from each other only in a single relative orientation.
