Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If 3D printing is performed without anomaly detection, then printing speed and productivity are maintained, but printing errors and calibration issues occur leading to resource waste and increased maintenance costs
Solution Approach 1:
The system performs preliminary anomaly detection by obtaining measurement data from the 3D printed object and comparing it against expected parameters before the printing process completes. This allows identification of printing anomalies and calibration issues early, enabling corrective actions to be taken before significant resource waste occurs, thus maintaining both productivity and reliability
Solution Approach 2:
The system establishes a feedback loop where measurement data from the printed object is continuously analyzed to detect printing anomalies. The generated instructions are fed back to adjust the 3D printer settings, creating a closed-loop control system that maintains printing accuracy without sacrificing productivity through real-time or near-real-time monitoring and adjustment
2Reliability
If measurement data is obtained and processed to detect printing anomalies, then printing accuracy and reliability are improved, but device complexity and operational costs increase
Solution Approach 1:
The system enables the 3D printer to self-diagnose and self-correct by automatically obtaining measurement data, processing it to identify anomalies, and generating adjustment instructions. This self-service capability improves printing accuracy without requiring complex external monitoring systems or manual inspection processes
Solution Approach 2:
The system focuses on monitoring and adjusting key printing parameters through measurement data analysis. By concentrating on critical parameters rather than comprehensive system monitoring, the solution achieves improved printing accuracy while maintaining relatively simple device architecture and avoiding excessive operational complexity
3Loss of substance
If printing anomalies are detected and addressed, then resource waste is reduced, but measurement and processing time are added to the workflow
Solution Approach 1:
The measurement and anomaly detection process is integrated into the printing workflow at strategic points, allowing detection before significant material is wasted. By performing measurements during or immediately after printing rather than after complete fabrication, the system minimizes both material waste and total measurement time required
Solution Approach 2:
The system applies partial measurement action by focusing on critical features and parameters of the printed object that are most indicative of printing anomalies. This selective measurement approach reduces the total measurement and processing time while still effectively identifying issues that would lead to material waste, achieving a balance between detection thoroughness and time efficiency
