Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual parameter adjustment is used to analyze phenotypical responses, then analysis accuracy can be maintained for specific cell types, but researcher burden and analysis time increase significantly
Solution Approach 1:
The system creates a digital model (copy) of the phenotypical response characteristics from training images. This model captures the essential features and parameter relationships, allowing automated analysis without requiring manual parameter adjustment for each new dataset, thus reducing analysis time while maintaining accuracy through the trained model's predictions
Solution Approach 2:
The system performs preliminary training using reference cell carrier images before actual analysis. During this training phase, the model learns the appropriate parameter settings and relationships for specific cell types and treatments. This preliminary action enables subsequent automated analyses to proceed without manual intervention, resolving the contradiction between accuracy and time consumption
2Adaptability or versatility
If multiple parameters are adjusted to quantify different phenotypical responses, then comprehensive analysis coverage is achieved, but device complexity and operational difficulty increase
Solution Approach 1:
The trained model serves as a universal tool that can analyze multiple types of phenotypical responses across different cell types and treatments. Instead of requiring separate parameter configurations for each response type, the single trained model handles diverse analysis needs, maintaining comprehensive coverage while eliminating the complexity of manual parameter adjustment
Solution Approach 2:
The system automatically determines and adjusts parameter values based on the trained model's predictions rather than requiring manual specification. The model internally manages parameter relationships and transformations, adapting to different phenotypical responses through learned patterns rather than predefined complex parameter sets, thus reducing operational difficulty while maintaining analysis comprehensiveness
3Productivity
If automated model-based analysis is implemented, then researcher burden is reduced and analysis efficiency improves, but initial model training complexity increases
Solution Approach 1:
The system performs self-training by automatically learning from reference cell carrier images without requiring extensive manual parameter specification or expert intervention during the training phase. The training process autonomously identifies relevant features and parameter relationships, reducing the burden on researchers while establishing the automated analysis capability that improves productivity
