Solution Overview

Problem

The manual processing of large volumes of patient data in emergency departments leads to delays in triage and treatment, complicating the assignment of orders among multiple patients, especially in urgent medical situations.

Innovation Solution

A machine learning-based system that utilizes synthetically generated images and heterogeneous data sources, including medical scan data and patient information, to rapidly assess and predict patient conditions, risks, and recommend missing information for more accurate diagnosis and triage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual processing of patient data is used, then data accuracy can be maintained through physician review, but triage speed and treatment efficiency deteriorate due to time-consuming analysis

Engineering Contradiction:
Improvediagnosis accuracyVSAvoidtriage time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system segments the complex diagnosis task into multiple components: an automated machine learning classifier performs rapid initial assessment of patient data, while physicians focus on reviewing and verifying critical cases. This division allows simultaneous automated processing and human oversight, reducing triage time while maintaining diagnostic accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The machine learning classifier acts as an intermediary between raw patient data and physician decision-making. It processes large volumes of data rapidly and presents prioritized results to physicians, who then make final diagnostic decisions. This intermediary layer accelerates information processing without eliminating human expertise.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If comprehensive patient data collection is performed, then diagnostic completeness improves, but processing complexity and time requirements worsen

Engineering Contradiction:
Improvediagnosis completenessVSAvoiddata processing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system extracts and prioritizes the most diagnostically relevant features from comprehensive patient data using machine learning. Instead of processing all data equally, the classifier identifies and focuses on key predictors of patient outcomes, reducing processing complexity while maintaining diagnostic completeness.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The machine learning model transforms raw patient data into optimized feature representations that capture essential diagnostic information in a condensed format. This parameter transformation reduces data dimensionality and processing complexity while preserving the information needed for accurate diagnosis.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If multiple patients are assessed simultaneously, then triage throughput increases, but assignment of treatment orders becomes more complex

Engineering Contradiction:
Improvetriage throughputVSAvoidorder assignment complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system performs preliminary risk stratification and prioritization for all patients simultaneously using automated machine learning classification before physicians assign treatment orders. This preliminary sorting reduces the complexity of order assignment by pre-organizing patients based on urgency and predicted outcomes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to physicians regarding predicted patient outcomes and risk levels, enabling more intuitive treatment order assignment. The automated predictions serve as feedback that guides physicians' prioritization decisions, simplifying the complexity of managing multiple patients simultaneously.

Inventive Principle:
Principle #23Feedback
