Solution Overview

Problem

Existing household appliance systems, such as washing machines and dishwashers, face challenges in achieving consistent cleaning results due to manual dosing of cleaning agents, which can lead to suboptimal dosing times or incorrect placement of dosing devices within the appliance, resulting in variable cleaning outcomes and reliability issues.

Innovation Solution

A method and device that utilize location detection through signal strength analysis from wireless communication networks to determine if a dosing device is correctly placed within the appliance's treatment room, ensuring accurate dosing and improved cleaning performance by outputting treatment room information based on detected location data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a dosing device is introduced into a treatment room of a household appliance, then automatic dosing of cleaning agents is enabled, but the dosing may occur too early, too late, or when the device is not in the treatment room, resulting in variable cleaning results

Engineering Contradiction:
Improveautomatic dosingVSAvoiddosing timing accuracy
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The system continuously monitors the location of the dosing device using wireless signal strength detection and provides feedback to the control unit. The control unit adjusts dosing operations based on real-time location information, ensuring dosing occurs only when the device is correctly positioned in the treatment room. This closed-loop feedback mechanism eliminates the reliability issues of premature, delayed, or misplaced dosing while maintaining automatic dosing functionality.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If manual dosing of cleaning agents is used, then the system is simpler to operate, but the cleaning results are variable and suboptimal

Engineering Contradiction:
Improvemanual dosing simplicityVSAvoidcleaning result consistency
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The dosing device is designed to autonomously monitor its own location via wireless signal strength and automatically control dosing operations without user intervention. The control unit self-regulates the dosing process based on detected location information, eliminating the need for manual dosing while ensuring consistent and reliable cleaning results. This self-service approach maintains operational simplicity while dramatically improving cleaning result consistency.

Inventive Principle:
Principle #25Self-service

3Device complexity

If the position of the dosing device is not monitored, then the device complexity is reduced, but the dosing accuracy and cleaning efficacy deteriorate

Engineering Contradiction:
Improveposition monitoring systemVSAvoiddosing placement accuracy
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The system replaces complex mechanical position monitoring mechanisms with wireless signal strength detection. The control unit determines the dosing device's location by analyzing the strength of wireless signals received from external networks, eliminating the need for physical sensors, switches, or mechanical detectors. This substitution maintains low device complexity while achieving high dosing placement accuracy and cleaning efficacy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
