Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional single cell techniques are used, then genetic analysis can be performed on individual cells, but the process is slow, tedious, and limited to analyzing only a handful of cells at a time
Solution Approach 1:
The system segments the cell analysis process into individual cell isolation within separate cell cages, allowing parallel processing of thousands of cells simultaneously. Each cell cage acts as an independent reaction chamber, enabling massive parallelization of nucleic acid extraction and analysis.
Solution Approach 2:
The cell cage array serves as an intermediary structure that bridges single-cell isolation and high-throughput analysis. The array format allows cells to be captured individually while maintaining organization for parallel processing, converting a sequential process into a parallel one.
2Productivity
If microfluidics or robotics are used to scale up single cell analysis, then more cells can be analyzed in parallel, but the equipment becomes costly and the process becomes complex
Solution Approach 1:
The cell cage array serves multiple functions: cell isolation, nucleic acid extraction, and parallel analysis platform. This multi-functional design eliminates the need for separate complex microfluidic devices or robotic systems, achieving high throughput with simpler, more versatile equipment.
Solution Approach 2:
The system uses inexpensive, disposable cell cage arrays that can be discarded after a single use, eliminating the need for expensive, complex, and difficult-to-maintain microfluidic devices or robotic systems. The low cost allows for high throughput without proportionally increasing equipment investment.
3Productivity
If microarrays with unique DNA barcodes are used, then parallel analysis of millions of cells becomes possible, but the system requires integration of multiple components and processes
Solution Approach 1:
The system merges cell cage array technology with microarray technology featuring unique DNA barcodes. This combination allows each cell to be individually isolated and simultaneously tagged with a unique identifier, enabling parallel tracking and analysis of millions of cells through a single integrated platform.
Solution Approach 2:
The system changes the scale parameter from analyzing handfuls of cells to millions of cells by implementing high-density cell cage arrays with unique DNA barcodes. This parameter change enables massive parallelization while the standardized protocol maintains simplicity despite the increased scale.
