Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing commercial dishwashing systems require high energy consumption and large amounts of detergent solutions to achieve effective hygiene, leading to increased operational costs and environmental impact, while also lacking precise control over hygiene effects.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional commercial dishwashing systems are used to achieve effective hygiene, then cleaning and disinfection results are improved, but energy consumption and detergent solution usage increase significantly
Solution Approach 1:
The system dynamically adjusts cleaning parameters (temperature, detergent concentration, mechanical action intensity) in real-time based on actual soiling conditions detected by sensors, rather than maintaining fixed high-level parameters throughout the cleaning cycle. This allows achieving effective hygiene results while reducing overall energy and chemical consumption.
Solution Approach 2:
The system incorporates sensors that continuously monitor cleaning effectiveness and soiling conditions, feeding this information back to the control unit which then adjusts cleaning parameters accordingly. This closed-loop control ensures hygiene reliability is maintained while optimizing resource usage to reduce energy consumption.
2Reliability
If conventional commercial dishwashing systems are used to achieve effective hygiene, then cleaning and disinfection results are improved, but detergent solution usage increases significantly
Solution Approach 1:
The system varies detergent concentration dynamically based on detected soiling conditions, applying higher concentrations only when and where needed rather than using uniform high concentrations throughout. This reduces overall detergent solution usage while maintaining effective hygiene results.
Solution Approach 2:
The system applies cleaning resources (detergent solution, mechanical action, heat) locally and selectively to areas with detected soiling rather than treating all items uniformly. This targeted approach reduces overall detergent consumption while ensuring hygiene reliability in contaminated areas.
3Reliability
If conventional commercial dishwashing systems are used to achieve effective hygiene, then cleaning results are improved, but operational costs and environmental impact increase
Solution Approach 1:
The system optimizes cleaning parameters (temperature, time, chemical concentration) based on actual needs, reducing unnecessary energy expenditure and operational costs while maintaining effective cleaning results through intelligent, adaptive control.
Solution Approach 2:
By continuously monitoring cleaning effectiveness and adjusting parameters in real-time, the system avoids wasteful expenditure of energy and resources, reducing operational costs while ensuring cleaning results meet hygiene requirements.
4Reliability
If conventional commercial dishwashing systems are used to achieve effective hygiene, then disinfection results are improved, but chemical additive usage increases
Solution Approach 1:
The system adjusts chemical additive concentrations dynamically based on detected contamination levels, applying disinfectants at higher concentrations only when and where hygiene risks are detected, thereby reducing overall chemical usage while maintaining effective disinfection results.
Solution Approach 2:
The system applies chemical additives locally to contaminated areas rather than uniformly to all items, reducing overall chemical additive usage while ensuring effective disinfection where needed based on sensor-detected soiling conditions.

AI summary
A method for cleaning items to be cleaned is disclosed. A cleaning device is used that has at least one cleaning chamber and at least one applicator for applying at least one cleaning fluid to the items to be cleaned in the cleaning chamber. A desired hygiene value is prespecified. The method further includes time-resolved recording of at least two influencing variables which influence hygienization of the items to be cleaned. Hygiene share values are determined from the influencing variables using a prespecified relationship between each influencing variable and the respective hygiene value share of said influencing variable. An expected actual hygiene value at the end of the cleaning from the hygiene value shares is ascertained and compared with the desired hygiene value. At least one of the influencing variables is changed based on the comparison. An inventive cleaning device is also disclosed.
