Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional onboard diagnostic systems are used to provide a snapshot of vehicle state, then the system complexity is low, but the ability to provide real-time monitoring and proactive notification of safety issues is insufficient
Solution Approach 1:
The diagnostic system is segmented into multiple independent modules: vibration sensors distributed at different vehicle locations, signal processing units, pattern recognition algorithms, and notification systems. This modular architecture enables real-time monitoring capabilities while managing system complexity through division of functions.
Solution Approach 2:
The system performs preliminary action by continuously analyzing vibration patterns and comparing them against stored signatures of abnormal conditions. This proactive approach detects potential safety issues before they manifest as actual problems, enabling early intervention and preventing failures.
2Loss of information
If vibration sensors and analysis circuits are added to enable real-time monitoring, then the reliability and proactive detection capability improve, but the device complexity increases
Solution Approach 1:
The system creates copies of normal vibration patterns and stores them as reference signatures in a database. By comparing real-time vibration signals against these stored copies, the system can detect deviations without requiring complex real-time analysis of every vibration parameter, thus reducing information loss while managing complexity.
Solution Approach 2:
Pattern recognition algorithms serve as intermediaries between the raw vibration data from sensors and the diagnostic conclusions. These algorithms process and interpret vibration signals, transforming complex sensor data into meaningful diagnostic information about vehicle condition and potential abnormalities.
3Measurement precision
If comprehensive vibration analysis is implemented to detect all abnormal conditions, then the measurement precision improves, but the device complexity and processing requirements increase
Solution Approach 1:
The system applies local quality by using different analysis methods and sensitivity thresholds for different vibration sensors located at specific vehicle positions. Each sensor zone is optimized for detecting local abnormalities, with tailored processing algorithms that match the expected vibration characteristics of nearby components, improving precision without requiring uniform complex analysis everywhere.
