Solution Overview

Problem

Conventional washing machines often require users to manually separate intertwined clothes after washing, drying, and spinning, increasing the burden of laundry work.

Innovation Solution

A clothes separating device integrated into a washing machine that includes a gripping unit and a force applying unit to separate entwined clothes within the washing tub, utilizing actuators, blowers, and moving members to efficiently untangle clothes, reducing the need for manual separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If clothes are washed, dried, and spun in a drum type washing machine, then the clothes processing function is improved, but the clothes become intertwined requiring manual separation increasing work burden

Engineering Contradiction:
Improveclothes processing functionVSAvoidmanual separation work
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The washing machine performs self-service by automatically separating clothes using a separator that grips and pulls apart intertwined garments, eliminating the need for users to manually separate clothes after washing

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

A separator acts as an intermediary mechanism between the washing process and the user, automatically handling the clothes separation task through gripping units that pull apart intertwined clothes

Inventive Principle:
Principle #24Intermediary (Mediator)

2Extent of automation

If a separator grips clothes to separate entwined items, then the automatic separation function is improved, but the device complexity increases

Engineering Contradiction:
Improveautomatic separation functionVSAvoidseparator mechanism
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The separator is segmented into multiple independent gripping units, each capable of independently gripping and separating clothes, which simplifies the overall control mechanism while maintaining effective separation functionality

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The separator incorporates detection units that provide feedback on the state of clothes and separation progress, enabling automatic adjustment of gripping force and separation actions to optimize performance while maintaining simple operation

Inventive Principle:
Principle #23Feedback
