Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional control systems are used for manufacturing, then device complexity is reduced, but measurement precision and response time for product quality deteriorate
Solution Approach 1:
The control system is divided into multiple independent modules including a data collection module that interfaces with PAT devices, a data processing module that performs real-time analysis, and a control module that executes adjustments. This segmentation allows each module to specialize in specific functions, improving measurement precision while managing overall system complexity through modular design.
Solution Approach 2:
A dedicated data processing module acts as an intermediary between PAT measurement devices and the control system. This intermediary layer performs real-time data analysis and transforms raw measurements into actionable control signals, enhancing measurement precision without requiring the entire control system to handle complex processing.
2Productivity
If real-time quality assessment is implemented, then productivity increases, but loss of time for data processing increases
Solution Approach 1:
The system performs preliminary data processing and quality assessment during the manufacturing process itself, rather than after completion. By continuously analyzing product quality parameters in real-time and making adjustments proactively, the system prevents defects before they occur, thereby increasing productivity without significant time loss.
Solution Approach 2:
The data processing and quality assessment operate continuously throughout the manufacturing process rather than in discrete batches. This continuous monitoring and adjustment eliminates idle time between measurements and maintains uninterrupted production flow, maximizing productivity while minimizing processing time delays.
3Extent of automation
If automation control strategies are implemented, then extent of automation increases, but device complexity increases
Solution Approach 1:
The automated control system is segmented into specialized modules: a data collection module for gathering PAT measurements, a data processing module for real-time analysis, and a control module for autonomous adjustments. This modular segmentation enables high automation capability while managing complexity through clear separation of functions and standardized interfaces between modules.
