Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual assessment of seminiferous tubules is performed by pathologists, then expertise-based classification can be achieved, but the process becomes time-consuming and highly subjective
Solution Approach 1:
The patent replaces the manual mechanical assessment process performed by pathologists with an automated digital image analysis system using machine learning algorithms. The system processes histological images of seminiferous tubules automatically, eliminating the time-consuming manual review while maintaining or improving classification accuracy through consistent algorithmic application.
Solution Approach 2:
The patent creates a digital copy of the manual assessment process by training machine learning models on annotated histological images. The system learns to replicate pathologist expertise through pattern recognition in digital images, enabling automated classification that preserves the accuracy of expert assessment while eliminating the time constraint.
2Measurement precision
If additional stained slides such as PAS stained slides are used for better visualization, then histological features can be assessed more accurately, but the complexity of the examination process increases
Solution Approach 1:
The patent develops a machine learning system that can extract multiple types of histological features and perform various assessments from a single H&E stained slide. The algorithm is designed to identify different cell types, structural features, and pathological changes using only the standard H&E stain, eliminating the need for multiple specialized stains while maintaining comprehensive assessment capability.
Solution Approach 2:
The patent transforms the assessment approach by changing from relying on visual parameters enhanced by multiple stains to using computational parameters extracted through image processing and machine learning. The system analyzes digital images with algorithms that can detect subtle features regardless of stain type, reducing the need for additional staining procedures.
3Reliability
If manual assessment is performed to detect subtle disturbances in spermatogenesis, then sensitive indicators can be identified, but the assessment becomes dependent on pathologist expertise and subjectivity
Solution Approach 1:
The patent replaces subjective human judgment with objective machine-based analysis. The machine learning system applies consistent algorithms to all images, eliminating variability between different pathologists and reducing subjectivity while maintaining the ability to detect subtle disturbances through pattern recognition in histological images.
Solution Approach 2:
The patent implements a feedback mechanism where the machine learning system is trained on annotated images with known outcomes, allowing it to learn from expert assessments and continuously improve its detection accuracy. The system provides objective results that can be validated and refined, reducing subjectivity while maintaining high sensitivity for detecting subtle changes in spermatogenesis.
