Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If predetermined rules are used for monitoring machine failures, then the system is simple to operate, but it ignores vast amounts of collected data leading to missed or inaccurate determinations
Solution Approach 1:
The system performs self-learning by automatically analyzing sensory data to identify failure patterns and generate updated monitoring rules without requiring manual intervention from operators. The machine learning model continuously improves its own monitoring capabilities by learning from historical failure data and sensor readings, enabling the system to adapt to new failure modes while maintaining operational simplicity.
Solution Approach 2:
The patent replaces traditional mechanical rule-based monitoring systems with an intelligent machine learning-based system. Instead of relying on predetermined rules that require manual configuration, the system uses neural networks and other ML algorithms to automatically detect failure patterns, substituting the mechanical approach with an intelligent one that can process vast amounts of sensor data while maintaining ease of operation through automated learning.
2Measurement precision
If all collected sensory data is analyzed using machine learning, then measurement precision improves, but device complexity increases
Solution Approach 1:
The system segments the complex machine learning task into distinct functional modules: data collection from multiple sensors, preprocessing and filtering of sensory inputs, feature extraction, pattern recognition using machine learning models, and failure prediction. This modular architecture allows each component to be optimized independently while maintaining overall system manageability and reducing complexity through organized data flow and processing stages.
3Ease of manufacture
If periodic testing at predetermined intervals is used, then the system is simple to implement, but it results in premature maintenance and wasted resources
Solution Approach 1:
The system performs preliminary failure detection by continuously analyzing sensory data and identifying patterns that precede actual machine failures. By detecting early signs of failure through machine learning analysis of sensor readings, the system can predict failures before they occur, enabling maintenance to be performed at the optimal time rather than through premature periodic replacement, thus avoiding wasted materials and expenses.
4Measurement precision
If specialized operators are required to operate monitoring systems, then measurement precision can be maintained, but productivity decreases due to human error and training requirements
Solution Approach 1:
The system performs self-learning by automatically analyzing sensory data to identify failure patterns and generate updated monitoring rules without requiring manual intervention from operators. The machine learning model continuously improves its own monitoring capabilities by learning from historical failure data and sensor readings, enabling the system to adapt to new failure modes while maintaining operational simplicity.
