Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibration absorbers for motor vehicle chassis components lack effective means to limit vibration amplitude in all directions, leading to potential damage from excessive stress on the elastomer body and risk of absorber mass detachment.
Innovation Solution
A vibration absorber design featuring an elastomeric spring member with an inner and outer sleeve, a securing element, and integrated stops that secure the absorber mass in axial and radial directions, preventing excessive movement and stress on the elastomer body, while allowing free vibration absorption within predefined paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional vibration absorber uses only a securing element for attachment, then the absorber mass can move freely to absorb vibrations, but the vibration amplitude cannot be limited in all directions leading to potential damage
Solution Approach 1:
The patent combines the securing element and stop functions into a single integrated component. The securing element features an integrated stop structure that limits vibration amplitude in all directions (axial and radial) while maintaining the absorber mass attachment function, thereby preventing component damage without requiring additional separate securing measures
Solution Approach 2:
The securing element is designed to perform multiple functions simultaneously: it secures the absorber mass to the elastomeric spring member, limits vibration amplitude in the axial direction, and limits vibration amplitude in the radial direction. This multi-functional design resolves the contradiction by providing comprehensive protection without increasing overall device complexity
2Reliability
If additional securing measures are added to limit vibration amplitude in all directions, then reliability improves, but manufacturing cost and device complexity increase
Solution Approach 1:
The patent merges multiple protective functions into the securing element itself. The integrated stop structure is formed as part of the securing element during manufacturing, eliminating the need for additional separate components and assembly steps, thereby maintaining ease of manufacture while improving reliability
Solution Approach 2:
The securing element is designed as a universal component that provides both attachment and vibration limiting functions in all directions. This multi-functionality reduces the total number of components required, simplifying manufacturing and reducing production costs while ensuring comprehensive protection

Function Achieved in This Case
The solution effectively limits vibration amplitude in all directions, preventing damage to the elastomer body and vehicle components, while allowing cost-effective production without additional securing measures, ensuring secure attachment and efficient vibration damping.
Implementation Method 1
The elastomer spring is thereby set in motion so that a damping effect is achieved due to the friction occurring in the elastomer spring
Implementation Method 2
an elastomeric spring member inserted in the passage of the absorber mass. The elastomeric spring member comprises an outer sleeve connecting the elastomeric spring member to the absorber mass, and an inner sleeve for attachment to the motor vehicle component

AI summary
A vibration absorber for damping vibrations of motor vehicle components. The vibration absorber comprises an absorber mass including a passage, and an elastomeric spring member inserted in the passage of the absorber mass. The elastomeric spring member comprises an outer sleeve connecting the elastomeric spring member to the absorber mass, and an inner sleeve for attachment to the motor vehicle component to undergo vibration absorption. An elastomer body interconnects the inner sleeve and the outer sleeve. The elastomeric spring member also includes a securing element. The vibration absorber includes stops that are spaced apart in an axial direction and that cooperate with the securing element to secure the absorber mass in the axial direction.
