Solution Overview

Problem

Compressors in clothes treating apparatuses generate vibration during refrigerant compression, which can be transferred to the apparatus, and increasing compressor capacity leads to increased volume, making it difficult to efficiently install larger compressors without compromising vibration isolation.

Innovation Solution

A fixing structure comprising a main bracket with a penetrating portion for the compressor and a sub bracket extending from it, along with a clamp to secure the compressor, is used to support the compressor, preventing vibration transfer and allowing for efficient installation of larger compressors by distributing the weight and securing the compressor at multiple points.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If the compressor capacity is increased to improve performance, then the compressor performance is improved, but the volume of the clothes treating apparatus increases

Engineering Contradiction:
Improvecompressor performanceVSAvoidapparatus volume
Core Design Contradiction:
PowerVSVolume of stationary object

Solution Approach 1:

The supporting structure is divided into a main bracket and a sub bracket. The main bracket supports the compressor body while the sub bracket extends to provide additional support and vibration isolation. This segmentation allows the compressor to be securely mounted without requiring a larger overall apparatus volume, as the distributed support structure efficiently utilizes available space.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sub bracket extends from the main bracket in a direction perpendicular to the main support structure, utilizing three-dimensional space more efficiently. This dimensional extension allows the supporting unit to provide stable support for a larger compressor without increasing the footprint or overall volume of the apparatus, as the support structure occupies vertical and lateral space rather than expanding the apparatus envelope.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Power

If the compressor capacity is increased to improve performance, then the compressor performance is improved, but the vibration generated by the compressor increases

Engineering Contradiction:
Improvecompressor performanceVSAvoidvibration
Core Design Contradiction:
PowerVSObject-generated harmful factors

Solution Approach 1:

The supporting unit acts as an intermediary between the compressor and the apparatus cabinet. The main bracket and sub bracket together form a vibration isolation system that captures and dampens vibrations at their source, preventing them from being transmitted to the cabinet and causing noise. This intermediary structure allows larger compressors to be used without proportionally increasing vibration transmission.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If a simple mounting structure is used, then the device complexity is reduced, but the vibration isolation effectiveness decreases

Engineering Contradiction:
Improvemounting structure complexityVSAvoidvibration transfer
Core Design Contradiction:
Device complexityVSObject-generated harmful factors

Solution Approach 1:

The mounting structure is segmented into a main bracket for primary support and a sub bracket for secondary support and vibration damping. This segmentation provides effective vibration isolation without requiring a complex multi-component system, as the two-bracket design achieves sufficient isolation while remaining structurally simple and easy to manufacture.

Inventive Principle:
Principle #1Segmentation
