Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of reaction sites is increased to process more samples simultaneously, then productivity is improved, but the complexity of organizing and visualizing the immense number of data points increases
Solution Approach 1:
The patent segments the immense dataset into manageable portions by dividing reaction sites into groups based on their spatial location on the chip. Each group can be visualized separately using scatter plots, allowing users to process and analyze data in organized segments rather than overwhelming all data points simultaneously.
Solution Approach 2:
The patent introduces multiple visualization dimensions including spatial location on the chip, fluorescent intensity values (FAM and VIC channels), and quality metrics. By displaying data points in a scatter plot with multiple axes and overlaying spatial chip representation, the system transforms complex multidimensional data into comprehensible visual formats that reveal patterns and anomalies.
2Measurement precision
If more data points are collected from additional reaction sites, then measurement precision is improved, but the difficulty of detecting and measuring data quality increases
Solution Approach 1:
The patent employs color-coded visual indicators to represent different data quality levels and statistical parameters. Scatter plot points are colored based on their quality metrics, and chip locations are color-coded to show data quality variations across the chip, enabling rapid visual assessment of data quality without requiring detailed numerical analysis of each data point.
Solution Approach 2:
The patent introduces intermediate visual representations including scatter plots and chip diagrams that serve as mediators between the raw immense dataset and the user's quality assessment. These intermediate visualizations aggregate and summarize data quality information, making it accessible and interpretable without requiring users to directly analyze individual data points.
3Measurement precision
If the sample volume is reduced to enable digital PCR, then the ability to detect rare alleles is improved, but the amount of data generated per unit volume increases
Solution Approach 1:
The patent combines data from multiple reaction sites and multiple fluorescent channels (FAM and VIC) into unified scatter plot visualizations. By merging related data points and showing their relationships in a single coordinated view, the system reduces the cognitive load of processing immense quantities of separate data points while maintaining the ability to detect rare alleles across the entire dataset.
