Solution Overview

Problem

Conventional laundry treatment apparatuses face issues such as the inability to wear clothes immediately after washing due to wrinkles, damage from frequent washing, high energy consumption, and a fixed presser position that limits movement.

Innovation Solution

A laundry treatment apparatus with a removably mounted presser that can be moved, featuring a hanger hook and press part hingedly connected to a support part, allowing for wrinkle removal and crease sharpening, along with steam or hot air drying and deodorization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the presser is fixedly mounted to a door, then the structure is simple and stable, but the position of the presser cannot be moved

Engineering Contradiction:

Improvepresser position flexibilityVSAvoidpresser mounting structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The presser is designed with a hinged connection between the press part and support part, allowing the press part to rotate and adjust its position dynamically. This enables the presser to move between different positions (pressed state and retracted state) while maintaining structural stability, resolving the contradiction between position flexibility and structural simplicity.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a rotary drum is used for washing, then washing function is provided, but wrinkles occur and energy consumption increases

Engineering Contradiction:

Improvelaundry treatment functionVSAvoidwrinkles and energy consumption

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The invention extracts and removes the rotary drum component from the laundry treatment apparatus. By eliminating the drum, the harmful effects of wrinkles caused by drum rotation and the high energy consumption associated with motor operation are removed, while retaining essential laundry treatment functions through alternative mechanisms like the presser and steam supply.

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If the press part is always in contact with the support part, then the structure is simple, but the presser cannot be moved or repositioned

Engineering Contradiction:

Improvepresser mobilityVSAvoidhinge connection structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The press part is hingedly connected to the support part, enabling rotational movement between these components. This hinge connection allows the presser to transition between different positions (contact and non-contact states) while maintaining structural simplicity, resolving the contradiction between mobility and structural complexity.

Inventive Principle:

Principle #15Dynamics
