Solution Overview

Problem

Existing clothing processing apparatuses fail to effectively minimize wrinkles and refresh clothing without increasing device volume or cost, and often risk worsening wrinkles, especially when dealing with garments on hangers.

Innovation Solution

A clothing processing apparatus that includes a steamer elevating vertically while applying mechanical tension to clothing through a spreader mechanism, which separates the body from arms to prevent wrinkling, using a blower to open the fabric for easier spreader insertion, and a multi-stage tension part for adjustable length, allowing for effective steam application without external mechanical forces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If steam is filled into the device without mechanical force application, then the device structure is simple, but the clothing is not spread taut and wrinkles cannot be effectively removed

Engineering Contradiction:
Improvedevice structureVSAvoidwrinkle removal effect
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

A spreader mechanism is introduced as an intermediary component between the steam generator and the clothing. The spreader applies mechanical tension to spread the clothing taut, enabling effective wrinkle removal while maintaining a relatively simple overall device structure. This intermediary mechanism resolves the contradiction by adding only the necessary minimal complexity to achieve the desired precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces complex multi-directional tensile force systems with a simpler single-direction spreader mechanism that moves linearly to apply tension. This substitution reduces device complexity while maintaining sufficient manufacturing precision for wrinkle removal by focusing mechanical action on the most critical dimension.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If a press method is employed to apply mechanical force, then the clothing can be spread taut, but the device volume increases and cost increases making it unsuitable for home use

Engineering Contradiction:
Improveclothing tensioning effectVSAvoiddevice volume
Core Design Contradiction:
Manufacturing precisionVSVolume of stationary object

Solution Approach 1:

The press mechanism is segmented into a compact linear spreader that moves along a guide rail, separating the tensioning function from the overall device structure. This segmentation allows the spreader to be a small, space-efficient component rather than a large voluminous press system, reducing device volume while maintaining clothing tensioning capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spreader is designed as a dynamic component that moves linearly to apply tension, replacing static large-volume press structures. This dynamic approach allows the same tensioning effect to be achieved with a much smaller component that occupies minimal space when not in use.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If clothing is placed on a floor frame for processing, then the device structure is simple, but the clothing may be ironed with wrinkles occurring

Engineering Contradiction:
Improvedevice structureVSAvoidwrinkle prevention
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The spreader acts as an intermediary between the floor frame and the clothing, applying controlled mechanical tension to prevent wrinkles during processing. This intermediary mechanism maintains the simplicity of the floor frame structure while adding the necessary wrinkle prevention function through the spreader's tensioning action.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Volume of stationary object

If steam is sprayed while moving along the surface of clothing, then the device can be compact, but severe and strong wrinkles are obtained when arm portions overlap the body portion

Engineering Contradiction:
Improvedevice volumeVSAvoidwrinkle removal quality
Core Design Contradiction:
Volume of stationary objectVSManufacturing precision

Solution Approach 1:

The spreader applies preliminary mechanical tension to the clothing before steam spraying begins. This preliminary action ensures that even overlapping portions such as arms are pre-stretched and positioned correctly, preventing severe wrinkles during the subsequent steam processing. The sequence of operations (tension first, then steam) resolves the contradiction between compact device volume and wrinkle removal quality.

Inventive Principle:
Principle #10Preliminary action
