Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual operations and artificial recognition are used for chromosome analysis, then doctors can recognize chromosome types based on their expertise, but the examination time is extended to two weeks or longer and the workload is heavier

Engineering Contradiction:
Improvechromosome recognition accuracyVSAvoidexamination time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces the manual mechanical recognition process with an automated deep learning system. The deep learning model automatically extracts features from chromosome images and classifies chromosome types, substituting the doctor's manual visual inspection and decision-making process. This automation dramatically reduces examination time from two weeks or longer to a much shorter automated processing time while maintaining high recognition accuracy through the model's learned patterns from training data.

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

2Measurement precision

If manual chromosome recognition is performed by experienced doctors, then recognition can be done with expertise, but the process is strongly subjective and easily influenced by external environment

Engineering Contradiction:
Improverecognition accuracyVSAvoidrecognition consistency
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The deep learning model achieves self-service by automatically learning chromosome recognition patterns from training data without requiring subjective human judgment. The model consistently applies the same learned features and classification rules to all chromosome images, eliminating variability caused by different doctors' expertise levels, fatigue, or external environmental influences. This self-service automation ensures reliable and consistent recognition results across different cases and time periods.

Inventive Principle:
Principle #25Self-service

3Productivity

If deep learning method is adopted for automatic chromosome recognition, then recognition efficiency is improved and workload is reduced, but the system requires building complex deep learning models

Engineering Contradiction:
Improvechromosome analysis efficiencyVSAvoidmodel building complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-training the deep learning model on a large dataset of chromosome images before deployment. The model learns chromosome features, patterns, and classification rules in advance during the training phase. When deployed for actual chromosome analysis, the pre-trained model can quickly and accurately recognize chromosome types without requiring complex real-time processing or manual intervention, thus improving productivity while the one-time training complexity is amortized over many subsequent efficient inferences.

Inventive Principle:
Principle #10Preliminary action
