Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If non-destructive evaluation techniques are used for aircraft maintenance, then inspection accuracy is improved, but labor intensity and time consumption increase
Solution Approach 1:
The maintenance decision-making process is segmented into distinct classification stages (inspection classification, repair classification, monitoring classification), with each stage handled by a dedicated machine learning model. This segmentation allows parallel processing of different maintenance aspects, improving overall efficiency while maintaining accuracy through specialized models for each classification type.
Solution Approach 2:
The patent replaces manual human judgment and traditional non-destructive evaluation methods with automated machine learning models. These models process multi-dimensional event data to generate maintenance classifications, substituting the mechanical and human-intensive inspection processes with computational algorithms that operate faster and with consistent accuracy.
2Adaptability or versatility
If human judgment is used to determine maintenance actions, then flexibility in decision-making is improved, but error rate increases
Solution Approach 1:
The system incorporates feedback mechanisms where maintenance outcomes and results are fed back into the machine learning models. This allows the models to learn from actual maintenance outcomes and continuously improve their decision-making accuracy while maintaining the flexibility to adapt to different aircraft events and maintenance scenarios through trained classification algorithms.
3Loss of information
If exploratory investigations are conducted to gather complete information, then decision completeness is improved, but time consumption and cost increase
Solution Approach 1:
The machine learning models are trained in advance on comprehensive datasets that include multi-dimensional event data from various aircraft maintenance scenarios. This preliminary training allows the models to quickly process and classify new maintenance events without requiring time-consuming exploratory investigations, as the necessary decision-making patterns have already been learned during the training phase.
