Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If deep neural network models are used for image analysis, then analysis accuracy is improved, but computational cost and data requirements increase significantly
Solution Approach 1:
The patent segments the image analysis task into distinct stages: initial contour detection using traditional algorithms, followed by targeted deep learning only for classification of detected cells. This segmentation allows traditional methods to handle the bulk of processing while deep learning enhances only the critical classification step, reducing overall data requirements.
Solution Approach 2:
The patent performs preliminary contour detection and cell isolation using traditional image processing algorithms before applying deep learning. This preliminary action filters and prepares the data, so that the deep learning model only needs to classify pre-processed cell images rather than learning from raw images, significantly reducing training data needs.
2Measurement precision
If deep neural network models are used for image analysis, then analysis accuracy is improved, but computational efficiency decreases
Solution Approach 1:
The patent divides the analysis pipeline into efficient traditional processing stages (contour detection, cropping, hole filling) and a focused deep learning stage for classification only. This segmentation ensures that computationally intensive deep learning is applied only where necessary, maintaining high overall efficiency while achieving accurate results.
Solution Approach 2:
The patent performs preliminary image processing operations (contour extraction, cell cropping, binary conversion) using efficient traditional algorithms before deep learning classification. This preliminary action reduces the complexity of input data for the neural network, enabling faster and more efficient computation while maintaining accuracy.
3Adaptability or versatility
If manual analysis is performed by diagnostic personnel, then flexibility and adaptability are maintained, but labor intensity increases and human errors occur
Solution Approach 1:
The patent implements an automated system where the diagnostic tool performs contour detection, cell extraction, and classification automatically without requiring manual intervention. The system serves itself by processing images through a pipeline of algorithms, eliminating labor-intensive manual analysis while maintaining diagnostic flexibility through configurable parameters.
4Productivity
If traditional contour recognition algorithms are used with ideal cell radius, then computational efficiency is improved, but handling of variable cell sizes may be limited
Solution Approach 1:
The patent uses dynamic contour detection that adapts to local image features rather than relying solely on a fixed ideal cell radius. The contour recognition algorithm dynamically adjusts to detect cell boundaries regardless of size variations, maintaining computational efficiency while handling variable cell sizes effectively.
Solution Approach 2:
The patent applies local quality by allowing the contour detection to adapt to local characteristics of each cell in the image. Instead of enforcing a uniform ideal radius, the algorithm detects contours based on local gradient information and intensity variations, enabling accurate detection of cells with varying sizes and shapes while maintaining overall computational efficiency.
