Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cytological examination and imaging techniques are used for cancer diagnosis, then the diagnosis can be performed and is relatively inexpensive, but the diagnosis becomes subjective and leads to indeterminate results
Solution Approach 1:
The patent replaces subjective mechanical examination methods with objective molecular profiling using gene expression analysis. The system uses algorithms to objectively classify tissue samples based on molecular signatures, eliminating the subjectivity inherent in cytological examination while maintaining cost-effectiveness through high-throughput molecular testing rather than expensive targeted therapies.
Solution Approach 2:
The patent changes the diagnostic parameters from morphological and structural parameters (used in cytology and imaging) to molecular parameters (gene expression profiles). This parameter transformation enables more precise and reliable diagnosis by measuring the actual molecular state of cells rather than relying on visual interpretation of tissue architecture.
2Measurement precision
If routine diagnostic methods are used, then the diagnosis process is simple and cost-effective, but the methods lack a rigorous method for determining the probability of an accurate diagnosis
Solution Approach 1:
The patent incorporates feedback mechanisms through algorithmic classification that continuously refines diagnostic probability assessments. The system provides quantitative probability estimates for diagnostic accuracy and automatically adjusts classification thresholds based on sample characteristics, giving clinicians rigorous probabilistic information without requiring complex manual analysis procedures.
Solution Approach 2:
The patent introduces computational algorithms as intermediaries between molecular data and diagnostic conclusions. These algorithms process complex molecular profiles and translate them into actionable diagnostic probabilities, simplifying the overall methodology while enhancing accuracy through standardized computational frameworks rather than complex manual protocols.
3Measurement precision
If current diagnostic techniques are used, then the diagnosis can be made, but the techniques are incapable of detecting a malignant growth at very early stages
Solution Approach 1:
The patent segments the diagnostic approach into multiple molecular pathways and gene expression profiles that can be independently analyzed. This segmentation allows detection of early molecular changes in specific pathways before they manifest as macroscopic tumors visible to conventional imaging, enabling early-stage cancer detection through molecular signatures.
Solution Approach 2:
The patent transitions from two-dimensional imaging and microscopy to three-dimensional molecular profiling by analyzing gene expression across multiple pathways simultaneously. This dimensional expansion enables detection of subtle molecular alterations that precede structural changes, providing earlier detection capability through comprehensive molecular characterization.
4Loss of information
If cytological analysis and imaging techniques are used, then the diagnosis can be performed, but the techniques do not provide information regarding the basis of the aberrant cellular proliferation
Solution Approach 1:
The patent makes the molecular profiling system multi-functional by simultaneously providing diagnostic classification, identification of aberrant pathways, and generation of treatment recommendations. This universal approach eliminates the need for separate diagnostic and mechanistic investigation systems, reducing overall complexity while comprehensive information about disease mechanisms through integrated molecular analysis.
