Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing washing machines require complex and costly emergency emptying systems for the suds drain line, which are prone to leakage and logistical complications due to separate components and assembly challenges.

Innovation Solution

Integration of the emergency emptying hose and drain line as a one-piece part, with a molded plug for sealing and simplified attachment, reducing the number of components and eliminating leakage risks, and incorporating a collection container integrated into the pump chamber for easy maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate emergency emptying hose and fastening means are used, then the system can provide emergency emptying functionality, but the number of components increases and assembly complexity increases

Engineering Contradiction:

Improveemergency emptying functionalityVSAvoidnumber of components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The emergency emptying hose is integrated directly into the drain line as a one-piece component, eliminating the need for separate fastening means and reducing the total number of parts while maintaining the emergency emptying function

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If multiple separate components are used for the emergency emptying system, then the system can be assembled, but assembly time increases and manufacturing costs increase

Engineering Contradiction:

Improvesystem functionalityVSAvoidassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The emergency emptying hose and drain line are manufactured as a single integrated component, eliminating multiple assembly steps and reducing manufacturing time while maintaining full system functionality

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If separate components with fastening means are used, then the system can be assembled, but leakage risk increases due to potential loosening or falling off

Engineering Contradiction:

Improvesystem functionalityVSAvoidleakage risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The emergency emptying hose is formed as an integral part of the drain line, eliminating connection interfaces that could loosen or fail, thereby completely eliminating leakage risk while preserving emergency emptying capability

Inventive Principle:

Principle #5Merging (Combining)

4Adaptability or versatility

If separate emergency emptying hose and plug are used, then the system can be configured flexibly, but logistics complexity increases due to reduced storage efficiency

Engineering Contradiction:

Improvesystem configuration flexibilityVSAvoidstorage requirements

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The emergency emptying hose and drain line are produced as a single integrated component, reducing the number of separate parts that need to be stored and managed in logistics while maintaining the ability to configure the system as needed

Inventive Principle:

Principle #5Merging (Combining)
