Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment of ink recipes is performed by well-trained personnel, then printing quality can be evaluated and adjusted, but extended downtimes of the printing machine occur
Solution Approach 1:
The system enables self-service through automated ink formulation adjustment. The control module automatically receives color measurement data from sensors, determines optimal ink recipes using AI algorithms, and transmits adjustment requests to the ink formulation module without requiring manual intervention by well-trained personnel, thereby eliminating extended downtimes while maintaining printing quality
Solution Approach 2:
The system implements continuous feedback loops where sensors measure spectral wavelength distribution and spectral intensity of printed products, compare measured values to target values, and automatically adjust ink formulations based on the comparison results. This closed-loop feedback mechanism enables real-time quality control without manual intervention or machine downtime
2Manufacturing precision
If complex systems with multiple operating steps are used to adjust ink recipes, then printing quality can be improved, but the systems become difficult to operate and require manual handling
Solution Approach 1:
The system performs self-adjustment of ink formulations through automated control. The control module independently processes color measurement data, calculates optimal ink recipes using AI algorithms, and executes adjustments without requiring manual handling or complex operating steps by personnel
Solution Approach 2:
The system replaces manual mechanical adjustment operations with automated digital control and AI-based algorithms. Instead of personnel physically adjusting ink parameters through complex manual procedures, the control module uses computational methods to determine and implement optimal ink formulations automatically
3Ease of operation
If traditional printing systems are used without ink formulation monitoring, then the system is simpler to operate, but the ink formulation cannot be correlated to printed product quality
Solution Approach 1:
The system establishes feedback connections between ink formulation data and printed product quality measurements. Sensors continuously measure spectral properties of printed products and feed this information back to the control module, which correlates the measurements with ink formulation parameters to enable automated adjustment of ink recipes based on actual print quality
Solution Approach 2:
The control module performs multiple functions including receiving color measurement data, analyzing spectral wavelength distribution and spectral intensity, determining optimal ink recipes using AI algorithms, transmitting adjustment requests to the ink formulation module, and monitoring ink quality. This multi-functional integration maintains system simplicity while enabling comprehensive ink quality correlation and control
4Productivity
If automated ink formulation adjustment is implemented, then productivity and printing process stability are improved, but device complexity increases
Solution Approach 1:
The system merges multiple previously separate functions into an integrated automated control system. The control module combines color measurement data reception, AI-based ink recipe calculation, and ink formulation adjustment control into a single unified system that automatically maintains printing process stability and improves productivity
Solution Approach 2:
The automated system performs self-adjustment of ink formulations without requiring manual intervention. The control module independently processes sensor data, determines optimal ink recipes using AI algorithms, and executes adjustments to the ink formulation module, enabling continuous stable operation and improved productivity through self-service automation
