Solution Overview

Problem

Existing clothes treatment apparatuses face limitations in effectively removing wrinkles from both top and bottom clothes within a limited space, often failing to apply sufficient physical force and frequently leaving wrinkles in bottom clothes untouched.

Innovation Solution

A clothes treatment apparatus featuring a panel assembly with rotatable panels that can be configured to apply tension or compression, allowing for the simultaneous treatment of top and bottom clothes using heated air or steam, thereby enhancing wrinkle removal efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a pressurizing panel and fixed panel structure is used to apply compression to clothes, then wrinkle removal effectiveness is improved, but the device occupies large volume and has complicated structure

Engineering Contradiction:
Improvewrinkle removal effectivenessVSAvoidapparatus volume
Core Design Contradiction:
Manufacturing precisionVSVolume of stationary object

Solution Approach 1:

The patent employs a movable panel assembly that can rotate between a storage position and a working position. The panel transitions from a static fixed state to a dynamic movable state, allowing the same structure to provide both compression force for wrinkle removal and space-saving storage. This dynamic transformation resolves the contradiction between needing large compression force and minimizing apparatus volume.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The panel assembly utilizes rotational movement to transition between positions, effectively using a different spatial dimension (rotation angle) to achieve both compact storage and effective working states. By changing the panel's angular position rather than its linear size, the system maintains wrinkle removal effectiveness while reducing the occupied volume when not in use.

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

2Quantity of substance

If a pressurizing structure with large size is used to treat more clothes, then the number of clothes treated at once is increased, but the pressurizing force is limited due to spatial restriction

Engineering Contradiction:
Improvenumber of clothes treatedVSAvoidpressurizing force
Core Design Contradiction:
Quantity of substanceVSForce

Solution Approach 1:

The pressing system is divided into multiple independent panels (first panel, second panel, third panel) that can be selectively positioned. This segmentation allows different combinations of panels to be used based on the number and type of clothes, enabling the system to provide adequate pressurizing force for each item while treating multiple clothes simultaneously. Each panel segment contributes force independently, resolving the contradiction between force magnitude and quantity of clothes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The panel assembly can dynamically adjust its configuration by rotating to different positions, allowing the system to optimize the number of active panels based on the loading condition. When more clothes are present, additional panels can be engaged to provide sufficient total force, while maintaining the ability to treat multiple items. This dynamic reconfiguration resolves the force limitation when treating larger quantities of clothes.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If a fixed panel structure is used to support clothes, then the structure is simple, but wrinkles of bottom clothes such as second clothes cannot be removed

Engineering Contradiction:
Improvestructure complexityVSAvoidwrinkle removal completeness
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The panel assembly rotates between a storage position (where panels are aligned) and a working position (where panels are staggered at different heights). This dynamic repositioning creates varied pressing surfaces that can accommodate different clothing types, including bottom clothes that require upward pressing force. The simple rotational mechanism maintains low structural complexity while achieving complete wrinkle removal across all clothing layers.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The support and pressing functions are segmented across multiple panels at different heights and positions. The first panel, second panel, and third panel can be independently positioned to provide targeted support for different parts of the clothes, including bottom clothes. This segmentation allows comprehensive wrinkle removal while maintaining a relatively simple overall structure based on modular panels.

Inventive Principle:
Principle #1Segmentation

4Manufacturing precision

If steam and heated air are supplied to clothes, then wrinkle removal effectiveness is improved, but energy consumption increases

Engineering Contradiction:
Improvewrinkle removal effectivenessVSAvoidenergy consumption
Core Design Contradiction:
Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The system combines mechanical compression force from the panel assembly with thermal treatment from steam and heated air in a single integrated process. The mechanical pressure from multiple panels works synergistically with the thermal effects, allowing effective wrinkle removal with reduced steam and heated air requirements compared to thermal-only methods. This merging of mechanical and thermal actions reduces overall energy consumption while maintaining effectiveness.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The panel assembly applies mechanical compression to the clothes before or during the steam and heated air treatment. This preliminary mechanical action pre-relaxes the fabric structure, making the subsequent thermal treatment more efficient and requiring less energy to achieve the same wrinkle removal effect. The sequence of mechanical pre-treatment followed by thermal treatment optimizes energy utilization.

Inventive Principle:
Principle #10Preliminary action
