Method for the dosing of cleaning agents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic dosing systems for cleaning machines struggle to accurately determine the optimal time for cleaning agent dosing, leading to inefficient energy and resource consumption, especially when retrofitting older machines, due to reliance on data from a single cleaning operation.
Innovation Solution
A method and device that utilize control information items about the cleaning machine, including its program structure, combined with sensor data and user input, to determine the optimal dosing time, allowing for precise adjustment of cleaning agent delivery based on the current cleaning state and machine operating state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile automatic dosing device is used to ensure universal applicability across different cleaning machines, then the device can be applied to various machines including older models, but the determination of optimal dosing time becomes inaccurate because it relies only on data from a single cleaning operation
Solution Approach 1:
The patent applies preliminary action by collecting control information items about the cleaning machine before the cleaning operation begins. This includes gathering data about the machine's program structure, operating parameters, and configuration settings in advance. By having this information available before dosing decisions are made, the system can accurately determine optimal dosing times without relying solely on real-time sensor data from a single operation, thus resolving the contradiction between universal applicability and measurement precision.
2Device complexity
If dosing decisions are made based only on real-time sensor data from a single cleaning operation, then the system remains simple and universally applicable, but the optimal dosing time cannot be accurately determined
Solution Approach 1:
The patent introduces an intermediary element - a database or storage system that holds control information items about the cleaning machine. This intermediary allows the dosing device to access comprehensive machine information without increasing the complexity of the dosing device itself. The control information items serve as a bridge between the simple mobile dosing device and the detailed machine characteristics, enabling accurate dosing time determination while maintaining device simplicity and universal applicability.
3Reliability
If too high a dosage of cleaning agents is used, then sufficient cleaning coverage is achieved, but unnecessarily high amounts of energy, cleaning agents and water are consumed
Solution Approach 1:
The patent implements feedback by continuously monitoring the cleaning state through sensors during the cleaning operation and comparing it with the planned dosing schedule based on control information items. The system can detect when cleaning objectives have been achieved and adjust or stop dosing accordingly. This feedback mechanism ensures that sufficient cleaning effectiveness is maintained while avoiding unnecessary consumption of energy, cleaning agents, and water by preventing over-dosing.
