Solution Overview

Problem

Conventional laundry treating apparatuses are inadequate in deodorizing bad smells and removing wrinkles, as they typically perform these functions while the drum is rotating, restricting effectiveness and requiring additional ironing for creasing clothes.

Innovation Solution

A laundry treating apparatus with a presser mechanism that includes a compression body and moisture supply unit to uniformly supply steam or hot air to clothes, allowing for precise creasing and wrinkle removal without changing the clothes' position, and the ability to handle multiple pieces of clothing simultaneously.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the drum rotates during deodorizing and wrinkle removal, then the laundry treating apparatus can perform these functions, but the effectiveness is restricted and additional ironing is required

Engineering Contradiction:
Improvedeodorizing and wrinkle removal effectivenessVSAvoidneed for additional ironing
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The compression body is designed to be movable, transitioning between a compressed state (pressing clothes against the support body) and a retracted state. This dynamic mechanism enables the apparatus to perform both drum rotation for washing and stationary compression for wrinkle removal and deodorizing, eliminating the need for additional ironing

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The laundry treating apparatus integrates multiple functions into a single system: the compression body serves as both a pressing mechanism for wrinkle removal and a deodorizing chamber when heated air or steam is supplied. This multi-functional design replaces the need for separate ironing and deodorizing operations

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

2Reliability

If the compression body presses clothes uniformly, then wrinkle removal is effective, but precise creasing in intended areas becomes difficult

Engineering Contradiction:
Improvewrinkle removal effectivenessVSAvoidprecise creasing position
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The compression body incorporates heating elements and steam supply ports at specific locations corresponding to intended crease areas. This localized treatment enables precise creasing in desired areas while maintaining uniform pressure across the entire garment for overall wrinkle removal

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The compression body is divided into multiple independent heating zones and steam supply regions, allowing different areas of the garment to receive targeted treatment. This segmentation enables simultaneous uniform pressing and localized precise creasing

Inventive Principle:
Principle #1Segmentation

3Productivity

If multiple pieces of clothes are pressed simultaneously, then productivity increases, but uniform treatment of divided areas becomes challenging

Engineering Contradiction:
Improvenumber of clothes treated per cycleVSAvoiduniform treatment of divided areas
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The compression body is divided into multiple independent compression zones that can be controlled separately. This allows different pieces of clothing or different areas of the same garment to receive uniform treatment simultaneously, maintaining precision while increasing productivity

Inventive Principle:
Principle #1Segmentation
