Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If machine-readable indicia are identified directly from printed content, then quality evaluation accuracy is improved, but computational load increases
Solution Approach 1:
The patent applies preliminary action by identifying machine-readable indicia in the buffer image before printing. The system locates indicia in the digital buffer image, determines their printed locations in advance, and prepares verification parameters beforehand. This allows the verifier to efficiently locate and evaluate printed indicia without performing intensive image processing on the actual printed content, thus maintaining evaluation accuracy while reducing computational load during printing operations.
2Measurement precision
If machine-readable indicia are identified from printed content, then verification accuracy is improved, but processing time increases
Solution Approach 1:
The system performs indicia location identification in the buffer image before printing occurs. By determining the locations of machine-readable indicia in advance and calculating their expected printed positions, the system prepares all necessary verification information beforehand. This preliminary processing eliminates the need for time-consuming image capture and analysis of printed content, significantly reducing processing time while maintaining verification accuracy through pre-computed location data.
Solution Approach 2:
The patent uses the buffer image as a digital copy of the intended printed content to perform indicia identification. Instead of processing the actual printed output, the system analyzes the digital buffer image which contains identical indicia information. This copying approach allows verification preparation to be performed on the digital replica, saving time while ensuring accurate location mapping to the printed output.
3Difficulty of detecting and measuring
If full buffer image is processed for indicia identification, then detection completeness is improved, but computational resources increase
Solution Approach 1:
The patent extracts only the essential information needed for verification from the buffer image. Instead of processing the entire buffer image for all possible analyses, the system specifically extracts machine-readable indicia locations and their corresponding printed position mappings. This extraction approach maintains detection completeness for verification purposes while significantly reducing computational resources by focusing only on relevant data elements.
Solution Approach 2:
The system uses the buffer image as an intermediary to obtain indicia locations without directly processing printed content. The buffer image serves as a mediator that contains all indicia information in digital form, allowing the system to extract location data efficiently. This intermediary approach provides complete detection capability while consuming fewer computational resources than direct printed content analysis would require.
