Solution Overview

Problem

Conventional laundry treatment apparatuses face issues such as wrinkles in laundry, damage from frequent washing, and high energy consumption due to motor operation, with fixed pressers limiting their functionality.

Innovation Solution

A laundry treatment apparatus with a removably mounted presser that applies pressure to remove wrinkles, featuring a hinge structure for rotation and a separation frame to prevent moisture contact, allowing for efficient wrinkle removal and crease sharpening while reducing energy consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a presser is fixedly mounted to a door, then the presser can apply pressure to remove wrinkles, but the position of the presser cannot be moved, limiting adaptability

Engineering Contradiction:
Improvewrinkle removal effectivenessVSAvoidpresser position flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The presser is designed with a movable structure that can rotate between a horizontal position (for wrinkle removal) and a vertical position (for storage or different operations). This dynamic positioning capability allows the presser to adapt to different operational needs while maintaining its wrinkle removal function, thus resolving the contradiction between operational effectiveness and position flexibility.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a rotary drum is used for washing, then washing function is provided, but energy consumption is high due to motor operation

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

Solution Approach 1:

The invention removes the rotary drum component entirely from the system. Instead of using a motor-driven drum for washing, the apparatus uses alternative mechanisms (such as the presser system and other non-motorized components) to achieve laundry treatment functions, thereby eliminating the high energy consumption associated with motor operation while maintaining washing capability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If steam or hot air is supplied to laundry, then wrinkle removal and deodorization are achieved, but moisture contact may cause damage to laundry

Engineering Contradiction:
Improvewrinkle removal and deodorizationVSAvoidmoisture damage to laundry
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

A separation frame is introduced as an intermediary component between the steam/hot air supply system and the laundry. This separation frame creates a barrier that allows thermal energy (steam and hot air) to reach the laundry for wrinkle removal and deodorization, while preventing direct contact with harmful moisture, thus resolving the contradiction between treatment effectiveness and moisture damage prevention.

Inventive Principle:
Principle #24Intermediary (Mediator)
