Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the printing device generates print data without considering the colors of the base material and adherend, then the printing process is simple and fast, but the colors produced in the image-forming layers become mixed with the colors of the base material and adherend, resulting in unwanted color mixing
Solution Approach 1:
The system performs preliminary detection of the base material and adherend colors before printing. The controller acquires color information of the base material and adherend in advance, then uses this information to generate accurate print data that compensates for the background colors, preventing color mixing while maintaining efficient printing speeds
Solution Approach 2:
The system changes the print data parameters based on the detected color conditions. By adjusting the print data according to the specific color values of the base material and adherend, the system compensates for color interference and achieves accurate color reproduction without requiring complex hardware modifications
2Device complexity
If the printing device generates print data without considering the conditions of the background area, then the printing process is simple, but the design formed on the second printing medium may deviate in position from the design provided on the first printing medium when overlaying
Solution Approach 1:
The controller performs preliminary detection of the background area conditions including color and shape information before generating print data. This advance acquisition of background information enables the system to calculate appropriate positioning adjustments, ensuring that designs on overlaid printing media align correctly without increasing hardware complexity
Solution Approach 2:
The system uses feedback from the detected background conditions to adjust the print data. By incorporating the actual color and shape information of the background area into the print data generation process, the system achieves precise positioning and alignment while maintaining simple printing hardware
