Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional diagnostic approaches are used, then ease of operation is maintained, but diagnostic accuracy deteriorates due to subjective judgment and overlooked clinical information
Solution Approach 1:
An AI-based diagnostic support system serves as an intermediary between healthcare providers and patient data. The system processes clinical information, applies Bayesian Theorem and Ockham's Razor algorithms, and generates differential diagnoses to assist providers, thereby improving diagnostic accuracy without replacing human judgment.
Solution Approach 2:
The patent replaces subjective mechanical diagnostic processes with an automated AI system that uses mathematical frameworks (Bayesian Theorem for probability calculation and Ockham's Razor for simplicity principle) to objectively analyze clinical data and generate ranked differential diagnoses.
2Measurement precision
If comprehensive clinical information is collected, then diagnostic accuracy is improved, but time consumption increases
Solution Approach 1:
The system performs preliminary analysis of clinical information by automatically processing and storing patient data, signs, symptoms, and clinical findings before the diagnostic process. This pre-processing enables rapid retrieval and analysis during actual diagnosis, reducing time consumption while maintaining comprehensive information collection.
Solution Approach 2:
The AI system provides feedback by generating ranked differential diagnoses based on the collected clinical information. This feedback loop allows healthcare providers to quickly review and adjust their diagnostic approach, efficiently utilizing the comprehensive data without excessive time expenditure.
3Measurement precision
If multiple diagnostic hypotheses are generated, then diagnostic accuracy is improved, but device complexity increases
Solution Approach 1:
The system changes parameters by dynamically adjusting the number and ranking of diagnostic hypotheses based on the complexity of the clinical presentation. Using Bayesian Theorem, the system calculates probability scores and generates an appropriate number of differential diagnoses (e.g., top 3-5 most likely conditions), balancing comprehensive analysis with computational efficiency.
Solution Approach 2:
The AI system applies partial action by generating only the necessary number of high-probability differential diagnoses rather than exhaustively listing all possible conditions. This selective generation approach maintains diagnostic accuracy while reducing the computational and presentational complexity of the output.

AI summary
A method of diagnosing medical conditions using artificial technology, which combines elements of Ockham's Razor and modified utilization of likelihood Ratio/Bayesian Theorem. The system employs standardized smart weight to assess presenting symptoms, assigning scores to each diagnosis related sign and symptom, and setting a generalized cut-off point to confirm diagnoses and link them with evidence-based treatments based on severity of illness scores calculated by the system, as well as simplified smart weight algorithms to achieve accurate results without relying on complex sensitivity and specificity data.
