Solution Overview

Problem

Existing vehicle component mounting systems face challenges in effectively decoupling high-frequency vibrations, particularly with steel springs that tend to develop stiffness peaks and require complex production processes when using elastomer springs.

Innovation Solution

A device comprising a support part, a damping element, and a stop element, where the damping element decouples vibrations and the stop element connects the bearing mount, allowing for axial and radial movement, using an elastomeric molding that is simple to manufacture and inexpensive, with adjustable stiffness for effective high-frequency vibration damping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If steel springs are used for decoupling vibrations, then high-frequency vibrations can be decoupled, but the springs tend to develop self-modes and stiffness peaks under high-frequency stimulation

Engineering Contradiction:

Improvevibration decoupling effectivenessVSAvoidstiffness peaks and self-modes

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces steel springs with elastomer elements that are simpler in structure and do not develop stiffness peaks or self-modes under high-frequency stimulation. The elastomer element is designed as a simple molded piece without complex coil structures, eliminating the harmful vibration modes inherent in steel springs while maintaining effective vibration decoupling.

2Ease of manufacture

If elastomer springs are used instead of steel springs, then manufacturing is simplified, but an additional sleeve is required for safe transmission of loads

Engineering Contradiction:

Improvespring manufacturing simplicityVSAvoidadditional sleeve and material bond connection

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges the functions of the elastomer spring and the additional sleeve into a single integrated elastomer element. The element is molded with built-in connection features including attachment surfaces for the bearing support and attachment surfaces for the component, eliminating the need for separate sleeves and material bond connections while maintaining load transmission safety.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The elastomer element serves multiple functions simultaneously: it provides vibration decoupling, transmits loads safely, and creates secure connections between components. The single element replaces what would traditionally require multiple separate components (spring, sleeve, connection elements), simplifying both manufacturing and assembly.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Strength

If a material bond connection is used between elastomer spring and additional spring, then connection is achieved, but production becomes complex

Engineering Contradiction:

Improveconnection strengthVSAvoidproduction complexity

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The patent replaces complex material bond connections with simple mechanical attachment surfaces molded directly into the elastomer element. These attachment surfaces provide secure connections through geometric interlocking rather than chemical bonding, dramatically simplifying production while maintaining connection strength.
