Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If expert experience-based evaluation is used, then clinical judgment can be made, but judgment accuracy and consistency deteriorate due to human factors

Engineering Contradiction:
Improveevaluation consistencyVSAvoidjudgment accuracy
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The patent replaces the mechanical system of human expert evaluation with an AI-based multimodal fusion evaluation system. The system automatically processes multiple data modalities (imaging, pathology, clinical data) through neural networks and fusion algorithms to generate objective evaluation results, eliminating human factors that cause judgment inconsistency and accuracy variation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The evaluation system is designed to universally process multiple data modalities including imaging data, pathology data, and clinical data through a unified multimodal fusion framework. This universal approach allows consistent evaluation across different data types and clinical scenarios, improving both reliability and precision simultaneously.

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

2Productivity

If manual evaluation methods are used, then clinical decision-making can proceed, but medical risk increases due to evaluation inaccuracies

Engineering Contradiction:
Improveevaluation efficiencyVSAvoidmedical safety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent replaces manual evaluation with an automated AI system that processes multimodal data through neural networks and fusion algorithms. This substitution maintains high evaluation efficiency while significantly improving medical safety by reducing evaluation errors and providing more reliable clinical decision support.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Loss of information

If multiple data modalities are integrated, then evaluation comprehensiveness improves, but system complexity increases

Engineering Contradiction:
Improvedata comprehensivenessVSAvoidsystem complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent segments the complex multimodal evaluation system into distinct processing modules for different data modalities (imaging module, pathology module, clinical data module). Each module processes its specific data type independently, and results are then fused through a dedicated fusion mechanism. This segmentation manages system complexity while maintaining comprehensive data integration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a multimodal fusion mechanism as an intermediary that integrates results from different data modalities. This fusion layer acts as a mediator that combines imaging features, pathology features, and clinical features into a unified evaluation result, managing the complexity of integrating multiple data sources while preserving comprehensive information.

Inventive Principle:
Principle #24Intermediary (Mediator)
