Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual labor-intensive steps are used in nucleic acid production, then flexibility and adaptability are maintained, but productivity is low and loss of time is high
Solution Approach 1:
The production system is divided into modular functional units including a nucleic acid production module, purification module, and quality control module. Each module performs specific functions independently, allowing parallel processing and automated workflow management, thereby increasing productivity while reducing overall production time through systematic organization of manufacturing steps
Solution Approach 2:
The system incorporates automated quality control sensors and feedback mechanisms that continuously monitor production parameters and automatically adjust process conditions without human intervention. The closed-loop control system self-regulates purification and production parameters, eliminating manual labor while maintaining high productivity and reducing production time
2Manufacturing precision
If centralized GMP facilities are used, then manufacturing precision and product quality are ensured, but device complexity and loss of time increase
Solution Approach 1:
The portable system integrates multiple functions including production, purification, and quality control into a single multi-functional platform. This universal design maintains GMP-grade manufacturing precision through automated standardized protocols while reducing device complexity compared to separate centralized facilities, enabling high-quality nucleic acid production in distributed locations
Solution Approach 2:
Automated robotic arms and transfer mechanisms serve as intermediaries between production modules, purification modules, and quality control sensors. These intermediary components enable precise material handling and process control that maintains manufacturing precision while simplifying the overall system architecture by automating complex transfer operations
3Manufacturing precision
If protein components are removed from nucleic acid, then product purity is improved, but productivity decreases due to additional purification steps
Solution Approach 1:
The purification module operates continuously with automated protein removal processes that run parallel to production monitoring. The system maintains continuous flow through the purification column with automated regeneration cycles, ensuring high nucleic acid purity while minimizing downtime and maintaining production efficiency through uninterrupted processing
Solution Approach 2:
The system dynamically adjusts purification parameters such as flow rate, buffer composition, and temperature based on real-time feedback from quality control sensors. By optimizing these parameters automatically, the system achieves high protein removal efficiency and nucleic acid purity while minimizing purification time and maintaining high productivity
4Manufacturing precision
If real-time monitoring is implemented, then manufacturing precision and quality control are improved, but device complexity increases
Solution Approach 1:
Manual quality control measurements are replaced with automated optical sensors, pH sensors, and conductivity sensors that continuously monitor production parameters in real-time. This substitution of mechanical/manual monitoring with electronic sensing systems improves manufacturing precision through continuous data collection while reducing overall system complexity by eliminating manual intervention points
