Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated systems are utilized to reduce human touchpoints, then contamination risk is reduced, but system cost and complexity increase significantly
Solution Approach 1:
The system is divided into multiple independent modules (cell collection module, cell processing module, cell expansion module, formulation module) that can be independently configured and operated. Each module handles specific tasks, allowing automation where needed while maintaining simplicity in other areas. This modular architecture reduces overall system complexity while enabling targeted automation to minimize contamination risk.
Solution Approach 2:
Closed transfer devices and sealed connectors act as intermediaries between modules, enabling automated material transfer without direct human intervention. These intermediaries maintain sterile barriers while facilitating process continuity, reducing contamination risk without requiring complete system redesign.
2Adaptability or versatility
If modular system is implemented to enable flexible production, then adaptability improves, but device complexity increases
Solution Approach 1:
The bioprocessing system is segmented into discrete, standardized modules that can be independently selected and configured based on specific production requirements. This allows flexible adaptation to different cell therapy products and scales without redesigning the entire system, managing complexity through modularity.
Solution Approach 2:
The modular modules are designed with universal interfaces and standardized protocols that allow them to be used across different applications and scales. A single module type can serve multiple functions depending on configuration, reducing the total number of unique components needed and simplifying the overall system architecture.
3Productivity
If parallel processing is implemented to improve productivity, then output increases, but system complexity and coordination requirements increase
Solution Approach 1:
The system architecture segments processing into independent modular units that can operate in parallel. Each module maintains its own control systems and protocols, reducing coordination complexity while enabling simultaneous processing of multiple cell therapy batches, thereby increasing overall productivity.
4Ease of operation
If manual operations are used to maintain operational simplicity, then ease of operation is maintained, but contamination risk and processing time increase
Solution Approach 1:
Closed transfer devices and automated connectors serve as intermediaries that simplify operations by eliminating manual opening and closing of sterile barriers. These intermediaries maintain sterility automatically while reducing the skill level and training required for operators, thus maintaining ease of operation while reducing contamination risk.
