Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual visualization and decision-making methods are used for classifying cells, then users can understand and interpret the classification process, but the process becomes labor-intensive and time-consuming
Solution Approach 1:
The system performs automatic classification of cells using machine learning algorithms without requiring manual user intervention for each classification decision. The computer device autonomously processes cytometric data sets, generates phenotypic profiles, and identifies optimal candidate compounds, thereby eliminating the labor-intensive manual visualization and decision-making process while maintaining or improving classification quality through algorithmic consistency
Solution Approach 2:
The patent replaces the manual mechanical process of visualizing and classifying cells with an automated computational system. Machine learning models and algorithms substitute for human analysts, automatically processing high-dimensional cytometric data, generating phenotypic profiles, and making classification decisions, thereby dramatically increasing productivity while maintaining reliability through systematic computational approaches
2Ease of operation
If conventional manual classification tools are used, then users can leverage visualizations to determine cutoff regions, but the process requires significant human effort and is prone to error
Solution Approach 1:
The system performs preliminary automated classification and generates phenotypic profiles before final candidate compound identification. By pre-processing the cytometric data sets and generating structured phenotypic profiles that capture essential characteristics, the system reduces the time required for subsequent analysis while maintaining user ability to review and control the classification outcomes through the structured profile format
Solution Approach 2:
The patent introduces phenotypic profiles as an intermediary representation between raw cytometric data and final classification decisions. These profiles serve as a structured intermediate format that preserves essential information while reducing complexity, enabling both automated processing efficiency and user interpretability without requiring direct manual analysis of raw high-dimensional data
3Extent of automation
If machine learning features are used instead of cytometric features, then automation is improved, but the features become hard to understand and interpret by users
Solution Approach 1:
The patent uses phenotypic profiles as an intermediary that bridges machine learning automation and user interpretability. The system automatically processes cytometric data through machine learning algorithms to generate structured phenotypic profiles that capture essential cellular characteristics in an organized format, allowing users to understand and interpret the results without needing to directly analyze complex machine learning features, thereby preserving both automation benefits and information interpretability
