Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If gene expression data analysis using machine learning algorithms is implemented, then prediction accuracy of severe disease is improved, but device complexity and computational requirements increase
Solution Approach 1:
The patent segments the complex prediction task into distinct components: (1) processing separate data types (gene expression data, clinical data, imaging data) through dedicated processing modules, (2) analyzing different immune cell types and pathways separately before integration, and (3) creating modular machine learning models that can be applied to specific patient populations. This segmentation reduces overall system complexity while maintaining high prediction accuracy.
Solution Approach 2:
The patent introduces intermediary elements including: (1) a standardized data processing layer that translates various data formats into unified representations, (2) intermediate feature extraction modules that identify key immune cell and pathway signatures before final prediction, and (3) intermediary validation steps that verify data quality and model performance. These intermediaries simplify the integration of complex components.
2Reliability
If comprehensive gene expression data from multiple sources is analyzed, then reliability of disease severity prediction is improved, but data processing time and computational resources increase
Solution Approach 1:
The patent implements preliminary actions including: (1) pre-processing and normalization of gene expression data from multiple sources before analysis, (2) pre-training machine learning models on large datasets to enable faster inference on patient-specific data, (3) pre-identification of key immune cell types and pathways that are most predictive of severe disease. These preliminary steps reduce processing time while maintaining reliability by focusing computational resources on the most informative data.
Solution Approach 2:
The patent extracts only the most relevant and informative features from comprehensive gene expression data, including: (1) specific immune cell type signatures that are strongly associated with severe disease outcomes, (2) key pathway activation patterns that predict disease progression, and (3) critical gene expression markers that provide high predictive value. This extraction reduces data volume and processing requirements while preserving prediction reliability.
3Adaptability or versatility
If immune cell and pathway gene signatures are identified to distinguish severe disease cases, then therapeutic targeting capability is improved, but analysis complexity and method difficulty increase
Solution Approach 1:
The patent applies local quality by: (1) identifying specific immune cell types and pathways with distinct gene expression signatures that are locally relevant to particular disease mechanisms, (2) creating tailored therapeutic strategies targeting specific identified pathways rather than applying uniform treatments, and (3) focusing analysis on specific gene sets and cellular compartments that are most relevant to each patient's disease profile. This localized approach enhances therapeutic precision while managing analysis complexity through focused rather than exhaustive examination.
