Solution Overview

Problem

Conventional washing machines have a detergent supply apparatus located on top, which complicates usability, is difficult to operate, and has a poor external shape, necessitating improvements for easier detergent access and aesthetic appeal.

Innovation Solution

A detergent supply apparatus is integrated into the bottom of the washing machine, featuring a detergent box with separate compartments for detergents and fabric softeners, a pump system for automatic dispensing, and a design that allows the detergent box to be easily withdrawn, enhancing usability and aesthetics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the detergent supply apparatus is located on top of the washing machine, then the detergent can be easily accessed, but the external shape becomes poor and operation becomes difficult

Engineering Contradiction:
Improvedetergent accessVSAvoidexternal shape
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The detergent supply apparatus is inverted from the conventional top location to a bottom location within the washing machine body. This inversion resolves the contradiction by placing the detergent supply at the bottom, which improves external appearance while maintaining accessibility through the door-mounted detergent box.

Inventive Principle:
Principle #13The other way round (Inversion)

2Shape

If the detergent supply apparatus is integrated into the bottom inside the body, then external shape is improved and usability increases, but the structure becomes more complex

Engineering Contradiction:
Improveexternal shapeVSAvoidapparatus structure
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The detergent supply apparatus at the bottom serves multiple functions: it maintains a clean external appearance, provides automatic detergent supply through the pump system, and allows easy access through the door-mounted box. This multi-functionality justifies the increased structural complexity by delivering multiple benefits simultaneously.

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

3Adaptability or versatility

If separate compartments for detergent and fabric softener are provided, then usability and storage capacity are improved, but the detergent box structure becomes more complex

Engineering Contradiction:
Improvedetergent storage capacityVSAvoiddetergent box structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The detergent box is segmented into separate compartments for different types of detergents and fabric softener. This segmentation allows users to store multiple products simultaneously while maintaining organized access, justifying the increased structural complexity through improved versatility and usability.

Inventive Principle:
Principle #1Segmentation
