Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current diagnostic methods are used, then thyroid cancer can be detected, but the accuracy is insufficient leading to unnecessary surgeries
Solution Approach 1:
The patent replaces subjective mechanical assessment methods with objective molecular genetic testing. By analyzing DNA polymorphisms (RET/PTC, PAX8/PPARG, BRAF mutations) rather than relying on cytological appearance, the system achieves higher diagnostic accuracy and reduces false positives, directly resolving the contradiction between measurement precision and reliability.
Solution Approach 2:
The patent changes the diagnostic parameter from morphological characteristics to molecular genetic markers. By detecting specific DNA polymorphisms and mutation patterns, the system transforms the basis of diagnosis to achieve greater precision and reliability, eliminating the trade-off between accuracy and false positive rate.
2Loss of information
If traditional diagnostic methods are used, then thyroid conditions can be identified, but underlying genetic pathways remain unknown
Solution Approach 1:
The patent extracts and analyzes specific genetic markers and polymorphisms from the complex DNA sequence. By focusing on particular regions (RET/PTC rearrangements, PAX8/PPARG fusion, BRAF V600E mutation), the system obtains valuable genetic pathway information without requiring complete genomic sequencing, thus reducing complexity while maintaining information gain.
Solution Approach 2:
The patent segments the diagnostic approach into distinct molecular tests for different genetic pathways. By separately analyzing RET/PTC, PAX8/PPARG, and BRAF mutations, the system makes the complex genetic information manageable and interpretable, reducing the perceived complexity while uncovering underlying biological mechanisms.
3Ease of operation
If subjective assessment methods are used, then diagnosis can be made, but treatment accuracy is reduced
Solution Approach 1:
The patent substitutes subjective cytological assessment with objective molecular diagnostics. By using DNA polymorphism detection and mutation analysis, the system provides precise, reproducible results that directly guide treatment decisions, eliminating the trade-off between ease of operation and treatment precision.
Solution Approach 2:
The patent implements a feedback mechanism where molecular diagnostic results directly inform treatment selection. By identifying specific genetic markers (RET/PTC status, PAX8/PPARG fusion, BRAF mutations), the system provides actionable feedback that enables precision medicine approaches, improving treatment accuracy while maintaining operational simplicity through automated testing protocols.
