Integrated Vibration Damper Assembly With Fewer Sealing Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration dampers with adjustable damping force are complex and difficult to install, requiring multiple components and sealing points that increase installation effort and risk.
Innovation Solution
A simplified vibration damper design integrates a pressure-stage adapter device with a one-piece design, eliminating additional sealing points and incorporating a pressure-stop damping element, allowing direct coupling to the damper-valve arrangement without an inner-pipe through-bore, and featuring a seal between the adapter and inner cylinder for easier installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate adapter sleeve component is used to connect the inner cylinder to the damping-valve device, then the vibration damper achieves adjustable damping force, but the device complexity and installation difficulty increase
Solution Approach 1:
The adapter sleeve is merged with the inner cylinder to form an integrated component. The adapter sleeve is no longer a separate part but is instead formed as an integral part of the inner cylinder, eliminating the need for separate assembly and reducing the number of components while maintaining the flow connection functionality to the damping-valve device
2Reliability
If multiple sealing points are used in the vibration damper assembly, then the sealing reliability is improved, but the installation effort and risk increase
Solution Approach 1:
By merging the adapter sleeve with the inner cylinder, the number of sealing points is reduced. The integrated design eliminates at least one sealing interface that would otherwise be required between separate components, thereby reducing installation effort and potential sealing failures while maintaining necessary sealing functionality
