Fragrancing and/or deodorizing a cleaning appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning appliances, such as dishwashers, face challenges in effectively managing odor loads due to constant and continuous dispensing of fragrancing agents, which fail to match the actual odor burden and cannot effectively remove unpleasant odors.
Innovation Solution
A method and device that capture odor load information using sensors, produce fragrancing and deodorizing information based on this data, and initiate the release of fragrancing and deodorizing agents accordingly, allowing for adaptive odor management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fragrancing agent is dispensed constantly and continuously, then the fragrance coverage is maintained, but the quantity of fragrancing agent used increases and the actual odor load cannot be effectively addressed
Solution Approach 1:
The patent employs odor sensors to continuously monitor the actual odor load in the cleaning appliance and uses this feedback information to control the dispensing of fragrancing agents. The control unit adjusts the dosing rate based on the detected odor burden, ensuring that fragrance is released only when and where needed, thereby maintaining effective odor coverage while minimizing unnecessary consumption of fragrancing agents.
Solution Approach 2:
The system transitions from static constant dosing to dynamic adaptive dosing. The fragrancing agent dispensing rate is continuously adjusted based on real-time odor sensor readings, allowing the system to respond flexibly to changing odor conditions inside the cleaning appliance, optimizing both effectiveness and resource utilization.
2Reliability
If a fragrancing agent is dispensed constantly, then odor coverage is maintained, but the ability to effectively remove unpleasant odors is reduced
Solution Approach 1:
Odor sensors provide real-time feedback on the actual odor composition and concentration, enabling the control unit to distinguish between different types of odors and adjust the fragrancing strategy accordingly. This allows for targeted deodorizing that addresses specific unpleasant odors rather than relying on constant masking fragrance release.
Solution Approach 2:
The system changes the parameters of fragrancing agent dispensing (rate, timing, concentration) based on detected odor conditions. When unpleasant odors are detected, the system can increase dosing or change the type of agent released, while under normal conditions it reduces or suspends dispensing, thereby improving odor removal effectiveness without compromising overall odor coverage.
3Device complexity
If fragrancing is carried out independently of actual odor burden, then the system operation is simple, but the fragrancing cannot be matched to the actual odor load
Solution Approach 1:
The patent integrates odor sensing and feedback control mechanisms that automatically monitor and respond to actual odor conditions. This adaptive approach, while more complex than constant dosing, provides the necessary adaptability to match fragrancing release to actual odor load, optimizing performance based on real-time environmental conditions.
Solution Approach 2:
The system performs self-monitoring and self-adjustment through integrated odor sensors and control units that automatically regulate fragrancing agent dispensing based on detected conditions, eliminating the need for manual intervention while achieving adaptive odor management.
Data Source
AI summary
A method for fragrancing and/or deodorizing a cleaning appliance is disclosed. The method involves capturing first information or obtaining captured first information indicative of an odor load in the interior of the cleaning appliance, producing fragrancing and/or deodorizing information based at least in part on the captured or obtained first information or outputting the captured first information in order to produce fragrancing and/or deodorizing information of this type, and initiating fragrancing and/or deodorization by employing at least one actuator for releasing a fragrancing and/or deodorizing agent based on the fragrancing and/or deodorizing information produced. A corresponding dosing device, a device for carrying out and/or controlling the method, and a system with one or more devices for carrying out and/or controlling the method are also disclosed.
