Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a self-contained sequencing system with multiple interdependent components is used, then the system can perform complete sequencing operations, but the system has limited scalability and high cost
Solution Approach 1:
The sequencing system is divided into separate, independent modules: a flow cell manufacturing system and a sequencing system. The flow cell system includes substrate preparation, oligonucleotide attachment, and amplification modules, while the sequencing system includes imaging and data analysis modules. These modules can be independently optimized, manufactured, and scaled without requiring complete system reintegration.
Solution Approach 2:
The flow cells are designed as universal substrates that can be used with multiple sequencing systems and configurations. The standardized flow cell interface and design allow the same flow cell to be used across different sequencing platforms, increasing system versatility and reducing the need for custom-built integrated systems for each application.
2Adaptability or versatility
If a self-contained sequencing system is used, then complete sequencing operations can be performed, but there is a time lag in introducing innovations to specific components
Solution Approach 1:
By separating the flow cell manufacturing system from the sequencing system, innovations in flow cell technology (such as new substrate materials, oligonucleotide attachment methods, or amplification protocols) can be developed and implemented independently in the flow cell system without requiring changes to the sequencing system hardware or software.
Solution Approach 2:
The system architecture allows dynamic updates and modifications to individual components. New flow cell designs can be rapidly prototyped and tested, then integrated into the sequencing system without redesigning the entire system, enabling continuous improvement and rapid adoption of innovations.
3Reliability
If a self-contained sequencing system is used, then complete sequencing operations can be performed, but the system has direct dependency of function on each component
Solution Approach 1:
The system is segmented into independent functional units with standardized interfaces. The flow cell system and sequencing system are physically and functionally separate, with well-defined interaction protocols. This segmentation eliminates the need for tight integration and reduces the complexity of maintaining system-wide dependencies.
Solution Approach 2:
Standardized flow cells serve as intermediaries between the substrate preparation process and the sequencing detection system. These flow cells have standardized interfaces and protocols that mediate the interaction between different system components, reducing direct dependencies and simplifying system integration.
