Dishwasher and method for operating a dishwasher
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Household dishwashers lack the ability to quickly complete a washing program without compromising the cleaning result, as users are limited to waiting or interrupting the cycle, leading to inefficiencies in time and resource usage.
Innovation Solution
A dishwasher with a control device that allows users to input and adjust the remaining washing time of a selected program, shortening it while maintaining a predefined cleaning result, by adjusting parameters such as water quantity, temperature, and program substeps, allowing for a faster completion of the cycle without repeating unnecessary steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a washing program with long runtime is selected to save resources, then energy and water consumption are reduced, but the washing time becomes too long for users who need items quickly
Solution Approach 1:
The washing program is made dynamically adjustable during execution. The control device allows users to intervene in a running program and modify parameters such as water temperature, water quantity, and program substeps in real-time, transforming a static program into a dynamic one that can adapt to changing user needs without restarting the cycle
Solution Approach 2:
The invention changes physical and operational parameters of the washing program during execution. By allowing modification of water temperature, water quantity, and program substeps, the system can shorten the remaining washing time while maintaining cleaning effectiveness, directly addressing the contradiction between energy efficiency and washing speed
2Duration of action of moving object
If a user interrupts a running washing program to get items quickly, then time is saved, but the cleaning result is no longer guaranteed
Solution Approach 1:
The control device provides continuous feedback to the user about the washing program status and allows user input during execution. This feedback mechanism enables users to make informed decisions about modifying the program while ensuring that any adjustments maintain the predefined cleaning result through controlled parameter changes
3Duration of action of moving object
If a fast washing program is selected to reduce washing time, then items are available quickly, but water and energy consumption increase
Solution Approach 1:
Rather than forcing users to choose between fast and eco programs at the start, the system allows dynamic adjustment during execution. Users can start with an eco program and selectively reduce time or resources based on actual needs, achieving a balanced solution that adapts to real-time requirements

AI summary
A dishwasher, in particular a domestic dishwasher, includes a control device configured to perform a number of washing programs for washing items to be washed, and an input means configured to register a user input for shortening a running selected washing program. The control device is configured to adjust the running selected washing program as a function of a registered user input in such a manner that a remaining washing time of an adjusted selected washing program is shortened compared with a regular remaining washing time of the running selected washing program.
