Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inspection methods are used to detect bacteria, then the system complexity is low, but the detection precision and reliability are insufficient to identify pathogenic bacteria strains accurately
Solution Approach 1:
The patent replaces manual visual inspection with an automated imaging system that captures microscopic images of bacterial colonies. The system uses optical sensors to capture images, which are then processed by machine learning algorithms to identify and classify bacteria, eliminating the need for manual microscopy and expert visual analysis while achieving high detection precision.
Solution Approach 2:
The system creates digital copies (microscopic images) of bacterial colonies on vehicle surfaces. These images serve as data representations that can be analyzed by machine learning models to identify bacteria types, allowing precise detection without requiring direct physical manipulation or expert human analysis of the actual bacteria.
2Reliability
If no prediction capability is implemented, then the system is simpler, but the ability to predict bacteria growth and enable timely sanitization is lost
Solution Approach 1:
The system performs preliminary actions by capturing images at multiple time points and using machine learning models to predict future bacterial growth trends. This allows the system to forecast when sanitization should be performed before contamination becomes severe, enabling proactive rather than reactive cleaning schedules.
Solution Approach 2:
The system establishes a feedback loop where bacterial growth data from repeated imaging is fed into machine learning models to refine predictions. The predicted growth trends then feed back into sanitization scheduling decisions, creating a closed-loop system that continuously improves its accuracy in predicting optimal cleaning timing.
3Reliability
If frequent manual cleaning is performed, then the cabin hygiene is maintained, but the time loss and operational disruption increase
Solution Approach 1:
The system performs preliminary detection and prediction actions by continuously monitoring bacterial growth and forecasting future contamination levels. This allows the system to schedule sanitization at optimal times before bacteria reach problematic levels, reducing the frequency and duration of actual cleaning operations while maintaining hygiene standards.
Solution Approach 2:
The system enables self-service monitoring where the automated imaging and prediction system continuously tracks bacterial growth without requiring constant human intervention. The machine learning models autonomously analyze images and predict growth trends, allowing the system to self-manage sanitization scheduling based on actual bacterial conditions rather than fixed schedules.
4Measurement precision
If no classification capability is implemented, then the system is simpler, but the ability to identify specific pathogenic bacteria strains is insufficient
Solution Approach 1:
The system creates detailed digital copies of bacterial colonies through microscopic imaging, capturing morphological characteristics that serve as identification markers. These image copies are then analyzed by machine learning models trained to recognize patterns associated with specific bacterial strains, enabling precise classification without requiring physical culture or molecular testing.
Solution Approach 2:
The patent replaces traditional bacterial identification methods (such as culture-based testing or molecular analysis) with automated image recognition. The system uses optical sensors to capture bacterial morphology and machine learning algorithms to classify strains based on visual characteristics, substituting complex laboratory procedures with automated digital analysis.
