Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional flow cell surfaces are used for primer attachment, then primer binding occurs, but primer concentration control is difficult and signal strength is insufficient
Solution Approach 1:
The flow cell surface is segmented into multiple dendron units, each containing multiple peripheral groups. This segmentation allows independent control of primer binding sites while maintaining overall surface organization, thereby enhancing signal strength through controlled primer concentration without excessive complexity
Solution Approach 2:
The invention transitions from a flat two-dimensional surface to a three-dimensional dendron architecture extending from the surface. This dimensional change increases the effective surface area and provides better spatial control over primer attachment, improving signal strength while distributing complexity across multiple dimensions
2Productivity
If flow cells are designed for single use, then sequencing operations can be performed, but resource efficiency is reduced due to inability to reuse
Solution Approach 1:
The flow cell design incorporates recoverable components that can be regenerated after use. The dendron architecture and surface chemistry are designed to allow removal and replacement of consumable elements while retaining the reusable substrate, enabling multiple sequencing runs and improving resource efficiency without compromising performance consistency
Solution Approach 2:
The flow cell is designed with universal features that allow it to perform multiple sequencing operations. The standardized dendron architecture and surface chemistry enable repeated use across different sequencing experiments, making the flow cell a multi-functional platform that improves productivity and resource utilization
