Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the verifier scans the printed content to capture an image for quality evaluation, then the quality assessment can be performed, but the computational load increases and operational efficiency decreases
Solution Approach 1:
The system performs preliminary actions by determining the location of machine-readable indicia in the buffer image before printing. This advance preparation allows the verification process to skip computationally intensive search operations and directly evaluate the printed content at known locations, thereby maintaining measurement precision while improving operational efficiency.
Solution Approach 2:
The system uses the buffer image (a digital copy of the content to be printed) to determine indicia locations before actual printing occurs. This copying approach allows quality evaluation parameters to be established in advance without requiring repeated scanning and analysis of printed content, reducing computational load during the verification phase while maintaining evaluation accuracy.
2Reliability
If the system determines the location of machine-readable indicia in the printed content after printing, then quality verification can be performed, but computational resources are excessively consumed
Solution Approach 1:
The system determines the location of machine-readable indicia in the buffer image before the printing operation. This preliminary determination of indicia locations allows the verification process to directly access known positions without performing computationally intensive image analysis on the printed content, thereby maintaining verification reliability while significantly reducing computational resource consumption during the quality evaluation phase.
3Measurement precision
If the verifier captures an image of the printed content for quality assessment, then the quality data can be obtained, but the process time increases
Solution Approach 1:
The system performs preliminary determination of machine-readable indicia locations in the buffer image before printing. This advance preparation enables the verification process to quickly locate and assess indicia in the printed content without performing time-consuming search operations, thereby maintaining quality assessment precision while minimizing the time loss associated with quality evaluation.
