Solution Overview

Problem

Conventional dishwashers lack specific washing programs tailored to the unique materials and requirements of components from external household appliances, leading to potential damage during cleaning.

Innovation Solution

A dishwasher with a storage unit for multiple washing programs and a communication unit that retrieves a specific washing program from an external device based on status information, ensuring optimal cleaning parameters for each component, such as temperature and cleaning agent usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional washing programs are used for components from external household appliances, then the dishwasher can clean various items, but the components may be damaged due to unsuitable washing parameters

Engineering Contradiction:

Improvewashing program adaptabilityVSAvoidcomponent integrity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The dishwasher dynamically adapts its washing program based on the type of component being cleaned. The control device selects from multiple washing programs (first, second, third programs with different parameters) based on input information about the component material and requirements, making the system flexible rather than static

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Different washing programs use different physical parameters (temperature, water flow, cleaning agent concentration) to match component requirements. The system changes these parameters dynamically based on the detected component type, ensuring optimal cleaning without damage

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the dishwasher stores multiple washing programs, then it can handle different component types, but the device complexity increases

Engineering Contradiction:

Improvewashing program varietyVSAvoidcontrol system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control device serves multiple functions: it identifies component types, selects appropriate washing programs, and executes the chosen program. This multi-functionality is achieved through a single integrated control unit rather than separate systems for each function

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Multiple washing programs are pre-configured in the control device with different parameters. This preliminary preparation allows the system to quickly select and execute the appropriate program without complex real-time calculations, reducing operational complexity

Inventive Principle:

Principle #10Preliminary action
