Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex algorithms are used for cell quality evaluation, then measurement precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent extracts and separates the complex algorithmic processing from the evaluation system by using straightforward image acquisition and counting methods. Instead of implementing complex algorithms within the evaluation apparatus, the system simply captures images and counts cells based on basic image analysis, leaving complex computational tasks outside the core device.
Solution Approach 2:
The system uses image copying and analysis rather than direct complex measurement. By capturing images of cells and using simple counting algorithms on these images, the system achieves evaluation without requiring complex physical measurement algorithms, thus simplifying the device while maintaining precision.
2Measurement precision
If complex algorithms are used for cell quality evaluation, then measurement precision is improved, but ease of operation worsens
Solution Approach 1:
The patent removes complex algorithmic operations from the user-operated evaluation process. The system automatically performs image acquisition and basic analysis, extracting the operational burden from the user and providing simple controls while maintaining high measurement precision through automated processing.
Solution Approach 2:
The evaluation system performs self-service by automatically acquiring images, analyzing cell structures, and generating quality assessments without requiring complex user operations. The system handles the entire evaluation process autonomously, from image capture to quality determination, making it easy to operate while maintaining precision.
3Measurement precision
If detailed statistical analysis is performed on cell culture data, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent applies partial action by performing only the necessary statistical analysis required for accurate cell quality evaluation. Instead of conducting exhaustive analysis on all possible parameters, the system focuses on key metrics such as cell count, confluence, and basic morphological features, achieving sufficient precision with reduced processing time.
Solution Approach 2:
The system extracts and separates time-consuming analysis tasks by using efficient image processing algorithms that quickly generate meaningful statistics. By focusing analysis on the most relevant parameters and using optimized processing methods, the system achieves high measurement precision without excessive processing time.
