Solution Overview

Problem

Traditional bell-shaped vibration-damping mounts require vulcanization to bind the elastic element to metal bodies, leading to high production and storage costs due to customization needs, and have inadequate anti-tear guarantees, making them costly and difficult to maintain, especially in harsh environments where the connection bushing can detach.

Innovation Solution

A modular bell-shaped vibration-damping mount that assembles components mechanically without vulcanization, using a bushing and disc-like element to securely attach the elastic element to the metal bodies, providing anti-tear resistance and allowing for easy replacement of the elastic element.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If vulcanization is used to bind the elastic element to metal bodies, then the connection strength is improved, but the production cost and storage complexity increase due to the need for customization

Engineering Contradiction:
Improveconnection strengthVSAvoidproduction and storage complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The mount is divided into separate modular components: metal bodies, elastic elements, and connection bushings. These segments can be independently manufactured and stored, then assembled through mechanical fastening rather than permanent vulcanization bonding. This allows standardization of components while maintaining strong connections through the bushing assembly mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A connection bushing is introduced as an intermediary component between the metal bodies and elastic elements. This bushing provides a standardized mechanical interface that replaces the need for custom vulcanization processes, enabling universal assembly while maintaining strong structural connections through threaded fastening.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If vulcanization is used to permanently bind components, then the structural stability is improved, but the ease of repair and replacement of elastic elements deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidease of elastic element replacement
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The mount structure is segmented into removable components, with the elastic element separated from the metal bodies by the connection bushing. This segmentation allows the elastic element to be independently replaced without damaging or replacing the metal bodies, while the overall structure remains stable through the robust bushing connection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The elastic element is designed as a replaceable component that can be discarded when worn or degraded, while the valuable metal bodies and connection bushings are recovered and reused. The mechanical assembly allows easy removal and installation of the elastic element without affecting the permanent components.

Inventive Principle:
Principle #34Discarding and recovering

3Ease of manufacture

If traditional chamfering is used to secure the bushing, then the manufacturing simplicity is improved, but the reliability deteriorates under high stress conditions

Engineering Contradiction:
Improvebushing installation simplicityVSAvoidbushing anti-tear guarantee
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The simple chamfering mechanical feature is replaced with a threaded fastening system. The bushing includes external threads that engage with internal threads in the metal body, providing a much stronger and more reliable connection that can withstand high stress and vibration conditions while remaining relatively easy to manufacture and assemble.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
