Solution Overview

Problem

Traditional federated learning approaches fail to account for diverse clinical protocols followed by different medical facilities, leading to suboptimal performance and increased false positives/negatives due to the use of a single central AI model not tailored to individual protocols.

Innovation Solution

A system that generates and deploys multiple AI models specific to different clinical protocols, allowing for localized training and updating based on feedback, reducing the need for human intervention and improving accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single central AI model is used for all medical facilities, then device complexity is reduced and ease of operation is improved, but clinical accuracy deteriorates and false positives/negatives increase due to inability to account for diverse clinical protocols

Engineering Contradiction:
ImproveAI model system complexityVSAvoidclinical accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent segments the single central AI model into multiple specialized AI models, each trained on specific clinical protocols. The central server maintains a repository of these segmented models and selectively deploys them based on the clinical protocol of each medical facility, thereby improving clinical accuracy while maintaining manageable system complexity through modular organization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by training different AI models on specific clinical protocols relevant to different medical facilities. Each AI model is specialized with local knowledge of its designated protocol, ensuring high clinical accuracy for that specific context while the overall system serves multiple facilities with diverse protocols.

Inventive Principle:
Principle #3Local quality

2Measurement precision

If multiple AI models specific to different clinical protocols are generated and deployed, then clinical accuracy is improved and false positives/negatives are reduced, but device complexity increases and the system requires more sophisticated model management

Engineering Contradiction:
Improveclinical accuracyVSAvoidAI model system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The central server is designed with multi-functionality to handle model training, repository management, selection, and deployment across multiple medical facilities. This universal platform manages the complexity of multiple specialized AI models through a single coordinated system that can adapt to different clinical protocols and facility requirements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system implements dynamics by enabling selective deployment of different AI models based on the clinical protocol of each medical facility. The central server dynamically chooses which specialized model to deploy based on protocol matching, allowing the system to adapt its complexity to the specific needs of each facility rather than maintaining fixed high complexity for all.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If AI models are customized for specific clinical protocols, then measurement precision is improved, but the time and resources required for model training and updating increase

Engineering Contradiction:
Improveclinical accuracyVSAvoidmodel training and updating time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-training multiple AI models on different clinical protocols and storing them in a repository before deployment. The central server has already performed the time-consuming training process in advance, so when a medical facility needs a model, the pre-trained model can be quickly selected and deployed without requiring real-time training, thus reducing the time loss for model acquisition.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where performance data from deployed AI models is collected and used to guide selective retraining or model updates. Rather than continuously retraining all models, the feedback-driven approach updates only those models that show performance degradation or protocol changes, reducing the overall time and resources required for model maintenance while preserving clinical accuracy.

Inventive Principle:
Principle #23Feedback
