Engineering Contradiction Analysis
1Ease of manufacture
If maintenance measures are carried out based on estimated values from development tests of different engine types, then maintenance can be performed without precise data, but the accuracy of efficiency assessment deteriorates and unnecessary maintenance occurs
Solution Approach 1:
The system implements feedback by continuously collecting actual maintenance effect data from engines after maintenance and using it to update and refine the functional relationships in the database. This closed-loop feedback mechanism allows the system to learn from real-world outcomes and improve the accuracy of its predictions over time, resolving the contradiction between ease of maintenance and assessment accuracy.
Solution Approach 2:
The system enables engines to effectively evaluate their own maintenance needs through the database management device that analyzes accumulated data from multiple sources. By self-servicing with data-driven insights rather than relying on generic estimates, the system achieves both ease of maintenance operation and high accuracy in efficiency assessment.
2Measurement precision
If comprehensive data collection and analysis systems are implemented to assess maintenance effects accurately, then assessment precision improves, but system complexity and costs increase
Solution Approach 1:
The database management device serves multiple functions: collecting data, storing historical information, analyzing maintenance effects, generating predictions, and providing recommendations. By consolidating these diverse functions into a single multi-functional system rather than separate specialized systems, the invention achieves high assessment accuracy while managing overall system complexity.
Solution Approach 2:
The database acts as an intermediary layer between raw maintenance data and decision-making processes. It accumulates and structures data from various sources, then provides processed information to the analysis system, simplifying the complexity of direct data-to-decision pathways while maintaining high assessment accuracy.
3Ease of operation
If maintenance measures are performed without analyzing their specific effects on engine efficiency, then maintenance procedures are simpler to execute, but engine performance optimization deteriorates
Solution Approach 1:
The system performs preliminary analysis of maintenance effects using the database and functional relationships before maintenance is executed. By predicting which maintenance measures will yield the best performance improvements in advance, the system enables maintenance personnel to execute simpler, more targeted procedures while achieving optimal engine performance outcomes.
