Antivibration Sound Insulation Device for Plant Noise Reduction

Solution Overview

Problem

Existing soundproofing treatments for plants are difficult to supplementally install after construction and cannot be easily disposed around inspection stands, requiring large-scale configurations that are not feasible for all noise reduction needs.

Innovation Solution

An antivibration sound insulation device comprising an antivibration mechanism attached to a stand near the sound source, with a sound absorbing sound insulation wall supported by the mechanism to surround the sound source, allowing for supplemental installation and placement around inspection stands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If soundproofing treatment is performed by surrounding the sound source, then soundproofing effect is improved, but installation flexibility deteriorates

Engineering Contradiction:

Improvesoundproofing effectVSAvoidinstallation flexibility

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The sound insulation wall is divided into multiple segments that can be independently installed and adjusted. This allows the soundproofing structure to be adapted to different spatial configurations and installed flexibly around existing equipment and stands while maintaining effective noise containment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The sound insulation wall is designed to extend in multiple spatial dimensions, creating a three-dimensional enclosure around the sound source. This multi-dimensional approach enables the structure to adapt to various plant layouts and accommodate stands and other equipment within or around the enclosure.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Object-affected harmful factors

If large-scale soundproofing structure is installed on floor part, then soundproofing effect is improved, but adaptability to existing plant layout deteriorates

Engineering Contradiction:

Improvesoundproofing effectVSAvoidadaptability to plant layout

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The sound insulation wall is divided into multiple segments that can be independently installed and adjusted. This allows the soundproofing structure to be adapted to different spatial configurations and installed flexibly around existing equipment and stands while maintaining effective noise containment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The sound insulation wall incorporates adjustable and movable components that can be reconfigured based on the existing plant layout. This dynamic design enables adaptation to various spatial arrangements without requiring fixed, large-scale floor installations.

Inventive Principle:

Principle #15Dynamics

3Object-affected harmful factors

If sound insulation wall is disposed around stand, then noise reduction is improved, but installation complexity increases

Engineering Contradiction:
