Solution Overview

Problem

Conventional laundry treatment apparatuses face issues such as wrinkles in laundry after use, damage from frequent washing, high energy consumption, and a fixed presser that limits mobility and efficiency.

Innovation Solution

A laundry treatment apparatus with a removable presser that can be moved, capable of performing washing, drying, deodorization, sterilization, and wrinkle removal, using a presser-fixing structure with elastic members for adjustable positioning and a cabinet design that allows for efficient use of space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

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

Engineering Contradiction:

Improvepresser position adjustabilityVSAvoidpresser mounting structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The presser is transformed from a fixed mounting to a movable mounting system. The presser can be positioned at multiple locations along the door inner surface and fixed at each position, enabling dynamic adjustment of presser location to accommodate different laundry pressing needs while maintaining structural simplicity through a standardized mounting mechanism.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the presser thickness is reduced, then the presser can be efficiently moved within the inner space, but the pressing force may be compromised

Engineering Contradiction:

Improvepresser mobilityVSAvoidpressing force

Core Design Contradiction:

Ease of operationVSForce

Solution Approach 1:

The pressing mechanism transitions from a thick single-dimension structure to a thin multi-dimension structure. By distributing the pressing function across multiple thin layers (presser body, elastic members, mounting structure), the overall thickness is reduced for better mobility while the cumulative pressing force across all layers maintains effective pressing capability.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

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

Engineering Contradiction:

Improvelaundry treatment functionVSAvoidmotor energy consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The rotary drum component is extracted and removed from the system. The washing, drying, and refreshing functions are achieved without a rotary drum by using alternative mechanisms such as steam injection, hot air circulation, and localized pressing, thereby eliminating the need for a motor and reducing energy consumption while avoiding drum-induced wrinkles.

Inventive Principle:

Principle #2Taking out (Extraction)

4Adaptability or versatility

If frequent washing with wash water is performed, then laundry cleanliness is improved, but laundry damage occurs

Engineering Contradiction:

Improvelaundry cleaning capabilityVSAvoidlaundry damage

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The mechanical washing system (rotary drum with wash water) is replaced with a thermal and chemical treatment system. Steam and hot air are used for cleaning and sanitizing laundry without the mechanical agitation that causes wrinkles and fabric damage, while still achieving effective cleanliness through thermal energy and chemical detergents applied during the treatment cycle.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A laundry treatment apparatus is disclosed. The laundry treatment apparatus includes a cabinet having an accommodation space formed therein to accommodate laundry, a door hingedly connected to the cabinet to open or close the accommodation space, a presser for applying pressure to laundry to remove wrinkles from laundry, and a presser-fixing structure for mounting the presser to the inner surface of the accommodation space or the door. The presser-fixing structure includes a support holder protruding from the inner surface of the accommodation space or the door and a presser-fixing recess formed concavely in the rear surface of the presser so as to allow the support holder to be inserted thereinto.
