Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual classification methods are used to identify mold particles, then human experts can make judgment calls on visually similar spores, but the process is time-consuming and prone to human error
Solution Approach 1:
The patent replaces the manual mechanical classification process with an automated digital microscopy system equipped with machine learning algorithms. The system captures images of mold particles and uses trained neural networks to automatically classify them, eliminating the need for manual human analysis while maintaining or improving classification accuracy and significantly reducing analysis time.
2Measurement precision
If traditional microscopy methods are used to distinguish between visually similar mold spores, then detailed examination can be performed, but accurate classification becomes difficult and error-prone
Solution Approach 1:
The patent transforms the classification approach by changing from visual parameter assessment to quantitative feature analysis. The machine learning system extracts multiple parameters from particle images (shape, size, texture, color distribution) and uses these transformed parameters to differentiate visually similar spores, achieving both high measurement precision and classification reliability.
Solution Approach 2:
The patent introduces machine learning algorithms as an intermediary between image capture and classification. The trained neural network acts as a mediator that processes raw particle images, extracts meaningful features, and produces accurate classifications, bridging the gap between visual similarity and accurate differentiation.
3Reliability
If extensive training data with accurate labels is used to train machine learning models, then classification accuracy improves, but data collection and labeling become time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-training the machine learning models using the SynthAspore system, which generates synthetic training images with automatically known ground truth labels. This preliminary training phase creates a robust base model that can be quickly adapted to specific applications, reducing the time needed for data collection and labeling in actual deployment scenarios.
Solution Approach 2:
The patent uses synthetic image generation to create copies of real mold particles with known characteristics. The SynthAspore system generates realistic training images that replicate actual particle appearances while providing accurate ground truth labels automatically, eliminating the need for time-consuming manual labeling of real particle images.
