Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual analysis of microscopic images is used, then interpretive flexibility and contextual understanding are maintained, but analysis time increases and human error occurs
Solution Approach 1:
The patent replaces the manual mechanical analysis process with an automated computer-based image analysis system that uses machine learning algorithms to detect and classify phenotypic attributes in microscopic images, eliminating human manual intervention while maintaining or improving analysis accuracy
Solution Approach 2:
The system enables self-service analysis where the computer automatically performs phenotypic analysis without requiring manual review or interpretation, allowing the system to independently identify, classify, and report phenotypic attributes from microscopic images
2Measurement precision
If a single machine learning model is used for all analysis tasks, then system complexity is reduced, but analysis precision and adaptability decrease
Solution Approach 1:
The patent divides the analysis task into multiple specialized machine learning models, each trained to detect specific phenotypic attributes or perform specific analysis functions, allowing each model to achieve high precision for its designated task while maintaining overall system manageability through modular architecture
Solution Approach 2:
The system employs multiple machine learning models that can be selectively applied based on the specific analysis requirements, allowing the system to adapt to different phenotypic attributes and analysis scenarios while maintaining a unified platform for automated image analysis
3Reliability
If all images are processed through all analysis models, then comprehensive analysis is achieved, but computational resources are wasted on unusable images
Solution Approach 1:
The patent implements a preliminary quality assessment step that evaluates images before they undergo full phenotypic analysis, filtering out unusable or low-quality images to prevent waste of computational resources while ensuring that only suitable images proceed to detailed analysis
Solution Approach 2:
The system applies different levels of analysis intensity to different images based on their quality and suitability, allocating full computational resources only to images that meet quality criteria while using minimal or no resources for unusable images, thereby optimizing overall resource utilization
4Productivity
If majority phenotype attributes are prioritized in analysis, then processing efficiency increases, but minority phenotype attributes may be overlooked
Solution Approach 1:
The patent applies different analysis strategies and model configurations for majority and minority phenotypic attributes, using specialized detection approaches for rare attributes that maintain high sensitivity while preserving overall analysis efficiency through differentiated processing pipelines
