Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cleaning operations are performed in ovens, then cleaning can be conducted, but cleaning consistency and reliability are poor due to variable product usage and placement
Solution Approach 1:
The system enables self-service cleaning by automatically detecting cleaning product presence through sensors and triggering cleaning cycles without manual intervention. The controller monitors sensor data to determine when cleaning products are present and autonomously initiates the cleaning process, eliminating variability in manual operation while maintaining cleaning effectiveness
Solution Approach 2:
The system implements feedback control by continuously monitoring sensor data regarding cleaning product presence and location. The controller processes this feedback information to determine whether cleaning products are properly positioned and present in required locations, then adjusts cleaning cycle initiation accordingly, ensuring consistent and reliable cleaning operations
2Reliability
If detection sensors are added to detect cleaning product presence, then cleaning reliability improves, but device complexity increases
Solution Approach 1:
The detection sensor serves multiple functions: it detects cleaning product presence, determines product location, and provides data for cleaning cycle initiation decisions. This multi-functionality reduces the need for separate specialized sensors, thereby limiting the increase in device complexity while achieving improved cleaning reliability through accurate product detection

AI summary
A system for controlling the initiation of a cleaning process for an interior of an appliance may include a detection sensor and a processor in communication with the detection sensor. The detection sensor may be configured to generate detection sensor data based on a sensed condition in a field of detection of the detection sensor which may comprise one or more pre-determined locations. The processor may control the initiation of an appliance cleaning process. The appliance cleaning process may comprise receiving detection sensor data representative of a first time and a second time, generating an initial condition based on the received detection sensor data representative of the first time, and generating a new condition based on the received detection sensor data representative of the second time. The processor may be additionally configured to compare the initial condition and the new condition and determine if cleaning product is present.
