Solution Overview

Problem

Conventional laundry treating apparatuses generate double creases due to the pressure applied to remove wrinkles, and they consume significant energy for rotating drums, while also risking damage from frequent washing.

Innovation Solution

A laundry treating apparatus with a clamp unit that fixes both ends of the laundry to prevent pressure on sewing lines, combined with a presser and supply unit for steam or hot air to perform washing, drying, deodorization, and wrinkle removal without generating additional creases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a presser is used to pressurize laundry to remove wrinkles, then wrinkle removal effectiveness is improved, but double creases are generated on the laundry

Engineering Contradiction:
Improvewrinkle removal effectivenessVSAvoidlaundry surface smoothness
Core Design Contradiction:
Manufacturing precisionVSShape

Solution Approach 1:

The presser applies pressure selectively to specific areas of the laundry rather than uniformly across the entire surface. By targeting only the regions with wrinkles while avoiding already-pressed areas and sensitive zones like sewing lines, the presser removes wrinkles without creating double creases. This localized approach allows different regions of the laundry to receive appropriate treatment intensity.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If a rotating drum is used for washing and drying, then washing and drying functions are achieved, but big energy consumption is caused

Engineering Contradiction:
Improvewashing and drying functionVSAvoidmotor energy consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The invention extracts and removes the rotating drum component from the laundry treating apparatus. By eliminating the drum, the system no longer requires motor-driven rotation for washing and drying operations. Instead, the apparatus uses alternative mechanisms such as steam injection, hot air circulation, and localized pressurization to achieve washing, drying, and wrinkle removal functions without the high energy consumption associated with continuous drum rotation.

Inventive Principle:
Principle #2Taking out (Extraction)

3Object-affected harmful factors

If frequent washing is performed to remove laundry-soaked smell, then deodorization is achieved, but damage of laundry is caused

Engineering Contradiction:
Improvelaundry-soaked smell removalVSAvoidlaundry integrity
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The invention utilizes phase transitions of water (liquid to vapor) through steam generation and injection. The steam penetrates the laundry fibers, effectively removing odors through thermal and moisture action without requiring vigorous mechanical washing. This gentle steam-based deodorization process eliminates the need for frequent harsh washing cycles that would otherwise damage the laundry fabric.

Inventive Principle:
Principle #36Phase transitions
