Solution Overview

Problem

Conventional damping systems for vehicle-mounted compressors, such as those in air conditioners and refrigerators, fail to provide adequate damping against complex and variable vibrations and shocks, leading to insufficient protection.

Innovation Solution

A compressor damping structure incorporating a first fixing plate with corrugated elastic structures and multiple damping pads, providing three stages of damping through the integration of a first and second damping structure and a third damping structure formed by the corrugated elasticity of the first fixing plate.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional stages of damping are introduced by adding more fixing plates and damping pads, then the damping effect is improved, but the number of components increases and cost problems arise

Engineering Contradiction:
Improvedamping effectVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the function of additional damping stages with the existing first fixing plate by utilizing its corrugated elastic structure. Instead of adding separate fixing plates and damping pads for the third damping stage, the corrugated structure of the first fixing plate itself provides the additional damping function, thereby reducing component count while maintaining enhanced damping performance.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The first fixing plate is designed with corrugated elastic structure that serves multiple functions: it acts as a structural support component and simultaneously provides the third damping stage through its elastic deformation characteristics. This multi-functionality eliminates the need for dedicated additional damping components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If more stages of damping are introduced with additional fixing plates and damping pads, then the damping effect is improved, but cost problems arise

Engineering Contradiction:

Solution Approach 1:

The patent combines the third damping function with the first fixing plate structure, eliminating the need for separate additional components. This merging reduces material costs, manufacturing complexity, and assembly costs while achieving enhanced damping performance.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If conventional damping systems are used, then the structure is simple, but the damping effect is limited and cannot meet complex and variable damping requirements

Engineering Contradiction:

Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent changes the structural parameter of the first fixing plate from a flat configuration to a corrugated elastic structure. This parameter change enables the plate to provide elastic deformation and energy absorption, creating a third damping stage that enhances the overall damping effect without significantly complicating the structure.
