Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual interpretation of medical images is used, then diagnostic accuracy is maintained, but time consumption increases and scalability is limited
Solution Approach 1:
The patent creates a digital representation (matrix) that copies and transforms the essential features of the medical image into a computationally efficient format. This matrix representation preserves the diagnostic information while enabling rapid automated processing, thus maintaining accuracy while improving speed and scalability.
Solution Approach 2:
The patent transforms the image data from its original pixel-based representation into a matrix of intensity values representing cell characteristics. This parameter transformation enables the data to be processed more efficiently by automated systems while maintaining the essential diagnostic information needed for accurate analysis.
2Measurement precision
If deep learning processes individual small-size patches, then detail capture is improved, but global arrangement information is lost
Solution Approach 1:
The patent segments the medical image into a matrix where each element corresponds to a spatial area, allowing localized feature extraction while maintaining global context through the overall matrix structure. This segmentation enables detailed analysis of specific regions without losing the global arrangement information encoded in the matrix dimensions and spatial relationships.
Solution Approach 2:
The patent transforms the 2D image into a matrix representation that adds an intensity dimension, creating a three-dimensional data structure (spatial x intensity). This dimensional transformation allows simultaneous capture of local features, global arrangement, and intensity information, resolving the contradiction between detailed patch analysis and global context preservation.
3Device complexity
If hand-crafted metrics are selected for image analysis, then feature extraction is simplified, but bias increases and problem-relevance decreases
Solution Approach 1:
The patent enables the system to automatically extract and represent cell characteristics without requiring manual selection of hand-crafted metrics. The matrix representation is generated through automated processing that identifies and encodes relevant features, eliminating human bias in feature selection while maintaining computational efficiency.
4Measurement precision
If original high-resolution medical images are processed directly, then detail preservation is maintained, but processing efficiency decreases
Solution Approach 1:
The patent extracts the essential diagnostic information from the high-resolution medical image and represents it in a compressed matrix format. This extraction process retains the critical spatial and intensity information while significantly reducing the data size and processing requirements, thus improving efficiency without sacrificing diagnostic precision.

AI summary
A method for analysing medical image data, the method comprising steps of: receiving medical image data comprising an image; using predetermined criteria to identify one or more subsets of cells in the image by identifying one or more characteristics of the cells; providing a matrix corresponding to the image comprising a plurality of elements, wherein each element corresponds to a spatial area in the image; populating the matrix by assigning an intensity value to each element in the matrix, the intensity value representing an intensity of a feature of the subset of identified cells in the corresponding area in the image, and processing the populated matrix to identify a classification for the medical image data.
