Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual assessment by trained pathologists is used to evaluate fibrosis, then diagnostic experience and clinical judgment are utilized, but the method is subjective, time-consuming, and bias-prone leading to potential misdiagnosis
Solution Approach 1:
The patent replaces the manual visual assessment mechanism with an automated image processing and analysis system. The system uses digital image processing algorithms to objectively quantify fibrosis characteristics in histopathological images, eliminating the need for time-consuming manual evaluation by pathologists while maintaining or improving diagnostic accuracy through consistent, bias-free measurement of fibrotic parameters.
Solution Approach 2:
The patent enables the histopathological images to self-evaluate fibrosis characteristics through automated analysis. The system extracts and quantifies fibrosis parameters directly from the images without requiring human intervention for measurement and scoring, allowing the diagnostic process to serve itself through algorithmic analysis of tissue morphology and fibrotic patterns.
2Measurement precision
If qualitative scoring of gross or biopsied tissue is used, then clinical decision-making is supported, but the method is inherently reliant on user observation and subjective estimation
Solution Approach 1:
The patent replaces subjective visual estimation with automated image processing and quantitative analysis systems. The system uses digital algorithms to objectively measure fibrosis parameters such as collagen deposition, tissue architecture, and cellular composition, providing precise numerical data instead of qualitative scores while managing complexity through standardized processing pipelines.
Solution Approach 2:
The patent transforms qualitative fibrosis assessment into quantitative parameter measurements. By converting visual observations into measurable parameters such as fibrosis area percentage, fiber density, and structural organization metrics, the system enables precise objective comparison and tracking of disease progression while maintaining manageable system complexity through defined measurement protocols.
3Measurement precision
If trained pathologists perform visual assessment, then clinical expertise is applied, but inter-observer variability and bias reduce measurement consistency
Solution Approach 1:
The patent replaces the human observation mechanism with automated image processing systems that apply consistent algorithms to all samples. This substitution eliminates inter-observer variability by ensuring that the same measurement criteria and analysis methods are uniformly applied across all histopathological images, providing reproducible results without requiring complex multi-validator systems.
Solution Approach 2:
The patent converts subjective scoring parameters into objective quantitative measurements that can be consistently measured and compared. By defining specific measurable parameters such as fibrotic area fraction, collagen fiber density, and tissue structural indices, the system achieves high measurement precision and consistency while keeping the analysis framework manageable through standardized parameter definitions.
