Solution Overview

Problem

Laundry treating apparatuses face challenges in maintaining cleanliness and hygiene within the detergent supply system, particularly due to detergent residue and foreign substances accumulating inside the housing, which complicates cleaning and affects user experience.

Innovation Solution

Incorporating a front shower portion in the dispenser to automatically supply water to the detergent storage, ensuring that the detergent supply casing is cleaned continuously, improving cleanliness and hygiene, and enhancing user convenience by facilitating efficient cleaning of the interior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If detergent storage is retracted or extended in the detergent supply, then detergent feeding function is improved, but detergent residue and foreign substances accumulate in the housing space, degrading hygiene and making cleaning difficult

Engineering Contradiction:
Improvedetergent feeding functionVSAvoiddetergent residue accumulation
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The detergent storage is extracted from the housing and made retractable, allowing it to be pulled out for detergent refilling and pushed back for automatic shower cleaning. This extraction principle enables the detergent storage to be separated from the housing during cleaning operations, facilitating hygiene maintenance while preserving the detergent feeding function.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If detergent storage is retracted or extended in the detergent supply, then detergent feeding function is improved, but cleaning of the housing space becomes difficult

Engineering Contradiction:
Improvedetergent feeding functionVSAvoidcleaning accessibility
Core Design Contradiction:
Ease of operationVSEase of repair

Solution Approach 1:

The system implements self-service cleaning through the automatic shower function that automatically cleans the housing space when the detergent storage is in the retracted position. This eliminates the need for manual cleaning intervention, making the cleaning process as easy as simply pushing the detergent storage back into place.

Inventive Principle:
Principle #25Self-service

3Object-affected harmful factors

If water supply is added to clean the detergent supply casing, then cleanliness and hygiene are improved, but device complexity increases

Engineering Contradiction:
Improvedetergent residue accumulationVSAvoidwater supply structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The water supply system is designed with multi-functionality, serving both as a cleaning mechanism for the detergent supply casing and as part of the overall detergent delivery system. The shower nozzles are integrated into the existing structure, allowing the same water supply infrastructure to perform multiple functions including detergent storage cleaning and housing space sanitation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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 effectively maintains cleanliness and hygiene within the detergent supply system by ensuring continuous cleaning during use, improving user experience and the overall cleaning performance of the apparatus.

Implementation Method 1

a water supply is disposed in a dispenser that supplies water to a detergent storage and the like, and water supply includes the front shower portion. Thus, water discharged from the front shower portion may be transferred to a front end of the detergent supply casing, so that auto shower may be performed.
