Solution Overview
Problem
Household dishwashers with both a metering apparatus and a supply unit for cleaning agents confuse users about which system is being used, leading to unclear operation and potential inefficiencies.
Innovation Solution
A household dishwasher with a control apparatus that integrates a supply unit for an individual dose of a first cleaning agent and an automatic metering system for a second cleaning agent, using sensors to detect the state of the metering system and emit signals to run appropriate washing programs, allowing users to choose between manual and automatic modes without complex programming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both a supply unit and an automatic metering apparatus are provided in the dishwasher, then the dishwasher offers greater versatility and adaptability, but the device complexity increases and ease of operation deteriorates due to user confusion about which system is being used
Solution Approach 1:
A sensor apparatus detects the state of the metering system (whether supply unit or automatic metering apparatus is present) and emits a sensor signal. The control apparatus uses this feedback to automatically determine which system to use, eliminating user confusion about which system is being used while maintaining both systems for versatility
Solution Approach 2:
The control apparatus automatically selects and operates the appropriate metering system based on sensor feedback without requiring user intervention or complex programming. The system serves itself by autonomously deciding which cleaning agent supply method to use, simplifying operation while preserving adaptability
2Adaptability or versatility
If both a supply unit and an automatic metering apparatus are provided in the dishwasher, then the dishwasher offers greater versatility, but the device complexity increases
Solution Approach 1:
The sensor apparatus provides automatic detection of the metering system state, and the control apparatus automatically selects the appropriate system based on this feedback. This automated control logic manages the complexity of having dual systems without requiring additional user-facing controls or complex programming interfaces
Solution Approach 2:
The control apparatus is designed to universally control both the supply unit and automatic metering apparatus through a single interface. This multi-functional control approach allows the system to offer versatility of both metering methods while maintaining a simple, unified control structure that does not increase apparent device complexity

AI summary
A household dishwasher includes a washing chamber, a control apparatus for running a washing program from a number of washing programs, a metering system having a supply unit for receiving an individual dose of a first cleaning agent and supplying the individual dose into the washing chamber at a metering point in time while running the washing program, and an automatic metering apparatus for automatically metering a plurality of metering quantities from a supply of a second cleaning agent in the form of a solid material into the washing chamber at the metering point in time, and a sensor apparatus configured to detect a state of the metering system and to emit a sensor signal depending on the detected state of the metering system. The control apparatus runs the washing program depending on the sensor signal.
