Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If array CGH technology is used to analyze DNA copy number variations, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent introduces a knowledge management tool as an intermediary system between array CGH technology and clinical interpretation. This tool compiles population frequency data and serves as a mediator that translates complex array CGH results into clinically actionable information, reducing the interpretive complexity while maintaining measurement precision
Solution Approach 2:
The patent creates a comprehensive database that copies and stores population frequency data for copy number variations. This copied reference data enables clinicians to compare individual patient results against population norms without requiring complex real-time analysis, thereby maintaining precision while reducing operational complexity
2Reliability
If comprehensive population databases are compiled to distinguish normal from disease-associated variations, then reliability of diagnosis is improved, but loss of time in data compilation increases
Solution Approach 1:
The patent performs preliminary action by pre-compiling population frequency data for copy number variations across the entire genome before clinical use. This advance preparation stores reference information that enables rapid comparison with patient samples, maintaining high diagnostic reliability while minimizing the time required during actual clinical testing
Solution Approach 2:
The knowledge management tool is designed as a dynamic system that can be updated and expanded with new population data over time. This dynamic structure allows the database to grow and improve reliability without requiring complete re-compilation, enabling incremental updates that maintain accuracy while reducing time investment
3Reliability
If ascertainment bias is avoided by studying unselected populations, then reliability of reference data is improved, but productivity of research decreases
Solution Approach 1:
The patent creates a universal knowledge management tool that serves multiple functions: it compiles data from unselected populations, stores population frequency information, provides diagnostic reference data, and supports clinical decision-making. This multi-functional system achieves reliable reference data from diverse population sources while improving research productivity through automated data integration and analysis
