Sleeved Damping Element Assembly for Axial and Radial Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening arrangements with damping effects have high assembly and manufacturing efforts, and they do not effectively address axial and radial oscillations/vibrations, often requiring complex configurations and locking structures.
Innovation Solution
A damping arrangement using two identically constructed damping elements with a central thru-opening and a single sleeve, where the sleeve is frictionally or materially connected to create a secure, tool-free fastening system suitable for various material thicknesses, reducing the number of components and assembly complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex fastening arrangements with multiple damping elements and locking structures are used, then damping effectiveness is improved, but device complexity and manufacturing effort increase
Solution Approach 1:
The patent combines multiple damping elements into a single integrated damping element with a specific geometric design. The damping element features a first portion and a second portion connected through a transition region, creating multiple damping zones within one component rather than requiring separate damping elements and locking structures.
Solution Approach 2:
The single damping element is segmented into functional zones: a first portion for axial damping, a transition region, and a second portion for radial damping. This segmentation allows different regions to address different vibration modes while maintaining a simplified single-component structure.
2Reliability
If multiple fastening devices are used on each component side, then secure fastening is achieved, but assembly time and manufacturing effort increase
Solution Approach 1:
The patent merges the functions of multiple fastening devices into a single fastening device that interacts with the multi-zoned damping element. This unified approach maintains secure fastening while eliminating the need for multiple separate fastening operations on each component side.
Solution Approach 2:
The single fastening device is designed to interact with multiple functional zones of the damping element simultaneously, achieving both axial and radial securing functions through one component rather than requiring specialized fastening devices for each direction.
3Reliability
If locking structures are added to prevent axial and radial oscillations, then vibration damping is improved, but device complexity increases
Solution Approach 1:
The damping element incorporates local geometric variations in its transition region that provide different damping characteristics for axial and radial directions. These localized geometric features create directional damping without requiring separate locking structures for each vibration mode.
Solution Approach 2:
The damping element may be constructed from viscoelastic materials that inherently provide damping across multiple vibration modes. This material-based approach to vibration control eliminates the need for mechanical locking structures while maintaining effectiveness against both axial and radial oscillations.

AI summary
A damping arrangement which is fastenable in an opening of a first component and by which a dampened connection of the first component with a second component is realizable, including, two identically constructed damping elements. Each damping element includes: a head portion with a first outer diameter, a shaft portion with a second outer diameter that is smaller than the first outer diameter and extends from a bottom side of the head portion, as well as a central first thru-opening, and only one sleeve with a central second thru-opening being arranged at least partly in the central first thru-opening of each damping element by means of a frictional and/or material connection. By means of the only one sleeve, the two identically constructed damping elements with bottom sides, facing each other, of the head portion with the first component arranged in between are fastenable to one another.
