Solution Overview

Problem

Conventional laundry treating apparatuses are inconvenient due to the elevated position of the detergent storage unit, requiring users to lift detergents high up for introduction, and often lead to clogging of the detergent supply channel.

Innovation Solution

A laundry treating apparatus with a detergent supply module featuring a module door, container, and pump to lower the detergent storage position, allowing easy detergent supply and incorporating a conduit system to prevent clogging by rinsing the detergent flow channel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the detergent storage unit is positioned at the upper portion of the laundry treating apparatus, then the detergent can be stored in a compact space, but the user experiences inconvenience when introducing detergent due to the elevated position

Engineering Contradiction:
Improvedetergent storage spaceVSAvoiddetergent introduction convenience
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The detergent storage system is divided into two separate modules: an upper detergent storage unit for compact storage and a lower detergent introduction portion for convenient user access. This segmentation allows each component to fulfill its specific function optimally without compromising the other.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A detergent supply module acts as an intermediary between the upper storage unit and the lower introduction portion. This module includes a detergent pump and conduit system that automatically transfers detergent from the elevated storage location to the accessible introduction location, eliminating the need for manual lifting while maintaining compact storage.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the detergent storage unit is positioned at the upper portion, then the structure is compact, but the detergent supply channel may become clogged due to gravity and flow issues

Engineering Contradiction:
Improveapparatus structureVSAvoiddetergent supply channel
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system performs preliminary rinsing of the detergent supply channel by introducing water before detergent supply and performing intermediate rinsing during the washing cycle. This preventive action removes detergent residues that could cause clogging before they accumulate to problematic levels.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The detergent supply channel undergoes continuous rinsing throughout the washing process rather than periodic cleaning. Water is continuously introduced through the channel during washing cycles, ensuring that detergent residues are constantly flushed out and preventing clog formation.

Inventive Principle:
Principle #20Continuity of useful action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution lowers the detergent storage position, simplifies detergent introduction, and prevents clogging by ensuring a constant detergent supply and regular rinsing of the detergent flow channel.
