Solution Overview

Problem

Noise and vibration generated during the operation of clothes treating apparatuses are leaked through the lower portion, causing discomfort and limiting space usage due to external propagation.

Innovation Solution

A noise leakage preventing device is installed at the lower portion of the clothes treating apparatus, comprising a noise blocking member and a noise blocking plate that are strategically positioned between the base and the ground, using materials with different densities and thicknesses to absorb and block noise, and are securely attached to the base using guide pins and adhesive pads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If legs are disposed on one side of the base to support the cabinet, then the cabinet is elevated by a predetermined height, but noise and vibration are propagated to the outside through the space between the legs and the lower surface of the base

Engineering Contradiction:
Improvecabinet elevationVSAvoidnoise and vibration propagation
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

A noise blocking plate is introduced as an intermediary component between the base and the ground. The plate extends under the base to block the propagation path of noise and vibration, while still allowing the legs to provide support elevation. This mediator prevents harmful factors from reaching the outside without compromising the supportive function.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The noise blocking plate extends in a horizontal dimension beyond the footprint of the base, creating a barrier that blocks noise propagation in the vertical transmission path. By adding this dimensional extension, the solution addresses noise propagation without interfering with the vertical support function of the legs.

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

2Reliability

If a noise blocking plate is provided with guide pins protruding from a surface, then the plate can be coupled to the base using guide pin accommodating portions, but the device complexity increases

Engineering Contradiction:
Improvecoupling stabilityVSAvoidnumber of coupling components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The guide pins on the noise blocking plate and the corresponding accommodating portions on the base create a self-aligning coupling system. During installation, the guide pins automatically guide the plate into the correct position, and the coupling occurs without requiring additional fastening operations or complex assembly procedures. This self-service mechanism ensures reliable coupling while maintaining simplicity.

Inventive Principle:
Principle #25Self-service
