Innovation Solution
A method and device that use a cleaning device with a cleaning chamber and application device to apply cleaning fluids, where a target hygiene value is specified, and influencing variables such as temperature, disinfectant concentration, and mechanical action are monitored and adjusted in real-time to achieve the desired hygiene level, allowing for precise control and reduced resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple fluid tanks and cleaning zones are used to increase throughput, then productivity is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts process parameters (temperature, transport speed, dosing rates) based on real-time monitoring of hygiene effectiveness, allowing optimization of energy consumption while maintaining productivity targets
Solution Approach 2:
Hygiene sensors provide real-time feedback on cleaning effectiveness, enabling the control system to adjust energy consumption parameters (heating, transport speed) to maintain hygiene standards while minimizing energy use
2Productivity
If multiple fluid tanks and cleaning zones are used to increase throughput, then productivity is improved, but the requirement for cleaning solution increases
Solution Approach 1:
Hygiene sensors monitor cleaning effectiveness in real-time, enabling the dosing system to adjust cleaning solution application rates precisely, reducing overall consumption while maintaining hygiene standards through targeted application
Solution Approach 2:
The system dynamically adjusts dosing parameters based on monitored hygiene effectiveness, optimizing cleaning solution distribution to maintain productivity while reducing total chemical consumption
3Reliability
If temperature and disinfectant concentration are increased to meet hygiene standards, then hygiene effect is improved, but energy consumption and chemical usage increase
Solution Approach 1:
Hygiene sensors provide real-time feedback on actual hygiene effectiveness, allowing the system to adjust temperature and disinfectant dosing dynamically, reducing energy and chemical consumption while maintaining required hygiene standards
Solution Approach 2:
The system optimizes process parameters (temperature, concentration) based on monitored hygiene effectiveness, finding the minimum necessary levels to achieve required hygiene standards rather than using fixed high levels
4Reliability
If temperature and disinfectant concentration are increased to meet hygiene standards, then hygiene effect is improved, but operational costs increase
Solution Approach 1:
Real-time hygiene monitoring enables dynamic adjustment of energy and chemical consumption, reducing operational costs by avoiding unnecessary resource use while maintaining hygiene compliance
Solution Approach 2:
The system dynamically optimizes temperature and chemical dosing parameters based on actual hygiene effectiveness, minimizing operational costs by using only the necessary amount of resources to achieve required standards

AI summary
A method for cleaning items (143) is proposed. The method uses a cleaning device (126) with at least one cleaning chamber (128) and at least one application device (130) for applying at least one cleaning fluid to the items (143) in the cleaning chamber (128). The method comprises the following steps: a. specifying a target hygiene value (110) to be achieved during cleaning; b. time-resolved acquisition of at least two influencing factors (112) that affect the sanitization of the items (143); c. determining hygiene value components from the influencing factors (114) using a predefined relationship between each influencing factor and its respective hygiene value component; d. determining a predicted actual hygiene value at the end of cleaning from the hygiene value components (120); e.Comparison of the expected actual hygiene value with the target hygiene value (122); and f. Influence of at least one influencing factor (124) depending on the result of the comparison.
