Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If vacuum is applied to stabilize documents during imaging, then document stability is improved, but device complexity increases due to vacuum system requirements
Solution Approach 1:
The patent applies vacuum pressure through a vacuum insert assembly to stabilize documents during imaging. The vacuum system creates negative pressure to hold the document firmly against the imaging surface, preventing movement and ensuring stable capture. This pneumatic approach directly addresses the stability requirement while accepting the associated device complexity.
Solution Approach 2:
The vacuum environment creates an inert atmosphere without air molecules between the document and imaging components. This vacuum state eliminates air currents and provides a controlled environment that stabilizes the document while enabling precise optical imaging without atmospheric interference.
2Measurement precision
If high resolution imaging is used to ensure accurate OCR, then measurement precision is improved, but loss of time increases due to processing requirements
Solution Approach 1:
The patent segments the image processing into multiple stages: capturing high-resolution images, creating thumbnails for quality control and metadata, and then processing only the necessary portions for OCR. This segmentation allows the system to maintain high measurement precision for OCR while reducing overall processing time by not treating all image data equally.
Solution Approach 2:
The system performs preliminary actions by creating thumbnails and metadata files during the imaging process itself, rather than after. Quality control assessments and metadata extraction are conducted in advance on the captured images, allowing the main OCR processing to proceed more efficiently from pre-processed data.
3Manufacturing precision
If multiple processing stages are implemented for quality control and metadata, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple processing functions into an integrated imaging system that handles quality control, metadata generation, and OCR processing in a unified workflow. Rather than separate devices performing each function, the system combines these operations to achieve manufacturing precision while managing complexity through functional integration.
Solution Approach 2:
The imaging system is designed with multi-functionality, where a single system performs document stabilization, high-resolution imaging, quality control assessment, metadata extraction, and OCR processing. This universal approach achieves high manufacturing precision across multiple quality dimensions while avoiding the complexity of multiple specialized devices.
