Solution Overview

Problem

Existing anti-vibration devices require a costly punching operation to block the first strength member in the slider, complicating the fabrication process and increasing production costs.

Innovation Solution

The first strength member is blocked in the slider using a snap-fitting mechanism, which can be integrated into the support and strength member during manufacturing, eliminating the need for punching and reducing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a punching operation is used to block the first strength member in the slider, then the strength member is securely blocked, but the fabrication process becomes more complex and costly

Engineering Contradiction:

Improveblocking reliabilityVSAvoidfabrication complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces the mechanical punching operation with a snap-fitting mechanism that uses elastic deformation and geometric interlocking. The elastic member deforms during assembly and locks the strength member in place through a snap-fit action, eliminating the need for punching while maintaining secure blocking.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The snap-fitting mechanism is designed to be self-assembling during the manufacturing process. The elastic member automatically engages with the strength member and slider through elastic deformation, eliminating the need for separate punching operations and reducing fabrication complexity.

Inventive Principle:

Principle #25Self-service

AI summary

An anti-vibration device comprising first and second strength members interlinked by an elastomer body adapted to work in compression mode along a main vibration axis is disclosed. The first strength member is fitted in a slider of a support, in a direction of fitting perpendicular to the main vibration axis. The first strength member is blocked in the slider by snap-fitting.
