Grooved Anti-Vibration Rubber Cylinders to Prevent Compression Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anti-vibration devices face issues with the deformation of anti-vibration rubber cylinders, where compression leads to radial distortion rather than straight deformation, compromising the durability of the cylinders.
Innovation Solution
The anti-vibration device incorporates peripheral grooves on the outer and inner peripheral surfaces of the anti-vibration rubber cylinders, allowing for easier and straight compression in the desired direction, preventing distortion and maintaining the static spring's integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the second anti-vibration rubber cylinder is compressed in the first direction, then the anti-vibration device can reduce vibration, but the rubber cylinder deforms in the radial direction and is distorted
Solution Approach 1:
The rubber cylinder is segmented by forming peripheral grooves on its outer peripheral surface and inner peripheral surface. These grooves divide the rubber material into multiple segments that can deform independently during compression, preventing radial distortion while maintaining the overall cylindrical shape and vibration reduction function.
Solution Approach 2:
The peripheral grooves create local differences in the rubber cylinder's structure. The grooved regions allow for controlled deformation while the areas between grooves maintain structural integrity. This local modification enables the rubber to compress straight in the first direction without developing radial deformations.
2Reliability
If the first anti-vibration rubber cylinder is compressed in the first direction, then the anti-vibration device can reduce vibration, but the rubber cylinder deforms in the radial direction and is distorted
Solution Approach 1:
The first rubber cylinder is also segmented by forming peripheral grooves on its outer peripheral surface and inner peripheral surface. This segmentation allows the rubber to compress in the first direction without radial distortion, maintaining both vibration reduction capability and structural durability.
Solution Approach 2:
The peripheral grooves create localized deformation zones in the first rubber cylinder, allowing it to compress straight while preventing radial bulging. This local structural modification ensures the rubber maintains its shape integrity during vibration absorption.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables the anti-vibration rubber cylinders to be easily compressed and deformed straight, enhancing their durability and preventing distortion during compressive deformation, thus effectively addressing the durability issues in conventional devices.
Implementation Method 1
an end of the second anti-vibration rubber cylinder that is located closer to the one of the vibration generating portion and the vibration receiving portion along the first direction is deformed in a radial direction, and as a result, the second anti-vibration rubber cylinder is not compressed and deformed straight in the first direction but is distorted
