If automated digital pathology analysis is introduced, then diagnostic efficiency is improved, but measurement precision of staining intensity decreases due to subjectivity

Engineering Contradiction:
Improvediagnostic efficiencyVSAvoidstaining intensity measurement precision
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent transforms the subjective visual assessment parameter into an objective computational parameter by using deep learning models to classify staining intensity into discrete categories (negative, weak, moderate, strong). This parameter change from subjective judgment to standardized classification improves measurement precision while maintaining automated efficiency.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system incorporates feedback mechanisms where the staining intensity detection model is trained on labeled data with ground truth annotations. This feedback loop allows the model to learn from correct examples and continuously improve its measurement precision, ensuring that automated analysis achieves high accuracy in staining intensity classification.

Solution Approach 1:

The patent segments the diagnostic process into distinct automated stages: image digitization, cell detection, staining intensity classification, and result generation. This segmentation allows each component to be optimized independently, with the staining intensity detection model focusing specifically on intensity classification while other components handle image processing and analysis, thereby improving overall productivity without sacrificing precision.

Inventive Principle:

Solution Approach 1:

The staining intensity detection model is designed with multi-functionality to handle various staining types and tissue samples through a single unified system. The model can process different immunohistochemical stains and tissue types, reducing the need for multiple specialized systems and thereby decreasing overall device complexity while maintaining high diagnostic speed.

Inventive Principle:
