Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional battery manufacturing processes are used, then production can proceed with simple systems, but safety and reliability cannot be ensured due to inability to manage deviations during production
Solution Approach 1:
The manufacturing execution system is divided into multiple independent modules including parameter monitoring module, deviation detection module, machine learning analysis module, and autonomous adjustment module. Each module performs a specific function in the deviation management process, allowing the complex system to be managed through modular components that can be developed, tested, and maintained independently while collectively ensuring safety and reliability.
Solution Approach 2:
The system performs preliminary actions by establishing parameter thresholds and deviation criteria before production deviations occur. Machine learning models are pre-trained with historical manufacturing data to recognize patterns of potential deviations. The system proactively monitors parameters and prepares adjustment strategies in advance, enabling rapid response to deviations before they result in quality issues or safety problems.
2Manufacturing precision
If manual monitoring and adjustment of manufacturing parameters are used, then system complexity can be reduced, but manufacturing precision and quality consistency deteriorate
Solution Approach 1:
The system implements continuous feedback loops where manufacturing parameters are monitored in real-time, compared against thresholds and historical data, and automatically adjusted based on machine learning model predictions. The system feeds back deviation information and adjustment results to continuously improve its models, creating a self-learning closed-loop control system that enhances manufacturing precision while managing automation complexity.
Solution Approach 2:
The manufacturing execution system performs self-service by autonomously detecting deviations, analyzing their causes using machine learning, determining appropriate adjustments, and implementing parameter modifications without human intervention. The system serves itself by maintaining its own performance through continuous learning from production data, automatically optimizing manufacturing precision while reducing dependence on manual operations.
3Manufacturing precision
If comprehensive parameter monitoring and deviation management are implemented, then product quality improves, but loss of time in processing and analysis increases
Solution Approach 1:
The system applies partial monitoring and analysis actions by focusing computational resources on parameters that show actual deviations or are接近 critical thresholds. Rather than continuously analyzing all parameters at full depth, the system intensively processes only those parameters that require attention, performing comprehensive analysis only when deviations are detected. This approach maintains high product quality while reducing unnecessary processing time for normal operating conditions.
4Measurement precision
If historical deviation data is extensively analyzed using machine learning, then deviation detection accuracy improves, but use of energy and computational resources increases
Solution Approach 1:
The machine learning analysis performs partial processing by selectively analyzing historical deviation data based on current production conditions and detected anomalies. Rather than continuously processing all historical data at full computational intensity, the system applies targeted analysis only when deviations are detected or when patterns suggest potential issues. This maintains high deviation detection accuracy while significantly reducing computational energy consumption during normal stable production periods.
