Sensor-Based Cleaning Agent Dosing for Universal Machine Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning machines face challenges in achieving optimal cleaning results due to inaccurate dosing of cleaning agents, leading to excessive energy and resource consumption, and lack of universal applicability in older machines.
Innovation Solution
A method for automatic dosing of cleaning agents that involves receiving control information about the cleaning machine, determining the progress of the cleaning process, and dispensing agents based on this information, using sensor-based detection and wireless communication to ensure precise dosing, thereby optimizing energy and resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile automatic dosing device is used to ensure universal applicability across older cleaning machines, then adaptability is improved, but dosing precision deteriorates because the device can only inaccurately determine the optimal time for dosing based solely on data collected during the cleaning process
Solution Approach 1:
The patent applies preliminary action by receiving control information about the cleaning machine before the cleaning process starts. This allows the dosing device to know in advance the program structure, water temperature, and other parameters, enabling precise determination of optimal dosing times before the actual cleaning begins, rather than trying to determine dosing timing during the process
2Device complexity
If dosing is based solely on data collected during the cleaning process, then device complexity is reduced, but dosing precision deteriorates leading to inability to achieve optimal cleaning results
Solution Approach 1:
The system receives control information before the cleaning process starts, including program structure and machine parameters. This preliminary data acquisition allows simple sensor-based detection during the process to achieve high dosing accuracy, as the foundation is already established from pre-process information
3Ease of operation
If underdosing or overdosing occurs, then ease of operation is maintained, but cleaning quality deteriorates and resource consumption increases
Solution Approach 1:
The patent uses sensor-based automatic detection to monitor the cleaning process and compares it with the received control information. This feedback mechanism allows the system to automatically adjust dosing to achieve optimal cleaning quality without manual intervention, preventing both underdosing and overdosing while maintaining ease of operation
