Solution Overview

Problem

Existing compressor noise suppression methods using sound-absorbing materials hinder heat dissipation, leading to increased compressor temperatures and vibrations, thus inadequately reducing noise.

Innovation Solution

A compressor noise suppressing structure that integrates a noise-proof member extending from an installation member to cover at least one side of the compressor, allowing for effective heat dissipation while blocking noise, and includes a detachable soundproof member and soundproof members extending from the blowing unit to further suppress noise transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the compressor is covered by a sound absorbing material component, then noise generated by the compressor is reduced, but heat dissipation is hindered leading to increased compressor temperature and vibrations

Engineering Contradiction:

Improvecompressor noiseVSAvoidcompressor temperature

Core Design Contradiction:

Object-affected harmful factorsVSTemperature

Solution Approach 1:

The sound absorbing material component is divided into multiple segments that can be selectively positioned around the compressor. This segmentation allows certain areas to be covered for noise reduction while leaving other areas exposed for heat dissipation, resolving the contradiction between noise suppression and thermal management

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the compressor housing have different levels of sound absorption material coverage. Critical noise-emitting areas are heavily covered while heat-dissipating surfaces are left exposed or minimally covered, creating local quality variations that simultaneously address both noise reduction and heat dissipation requirements

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If the compressor is covered by a sound absorbing material component, then noise generated by the compressor is reduced, but vibrations increase due to poor heat dissipation

Engineering Contradiction:

Improvecompressor noiseVSAvoidcompressor vibrations

Core Design Contradiction:

Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The sound absorbing component is segmented to provide selective coverage, allowing noise-prone areas to be covered while heat-dissipating areas remain exposed. This prevents temperature-induced vibrations while maintaining noise suppression where needed

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Variable coverage density of sound absorbing material creates local quality differences that prioritize heat dissipation in critical thermal zones while providing noise suppression in acoustic-sensitive zones, thereby reducing vibrations caused by thermal overload

Inventive Principle:

Principle #3Local quality

3Object-affected harmful factors

If separate components are used for housing and noise-proofing, then noise suppression is effective, but assembly process becomes complex and manufacturing costs increase

Engineering Contradiction:

Improvecompressor noiseVSAvoidassembly process complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The housing and noise-proofing components are merged into a single integrated structure. The sound absorbing material is incorporated directly into the housing design, eliminating the need for separate assembly steps and reducing manufacturing complexity while maintaining effective noise suppression

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated housing structure serves multiple functions simultaneously: structural support, noise suppression, and heat dissipation management. This multi-functionality reduces the total number of components and simplifies the assembly process while achieving the desired noise reduction performance

Inventive Principle:

Principle #6Universality (Multi-functionality)
