Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual processing methods are used with numerous human touchpoints, then flexibility in process adaptation is maintained, but contamination risk increases and manufacturing efficiency decreases
Solution Approach 1:
The system is divided into separate closed modules (enrichment module, expansion module, harvesting module) that can be independently connected and operated. This segmentation allows automated processing within each module while maintaining process flexibility through modular configuration, reducing human touchpoints without sacrificing adaptability.
Solution Approach 2:
The closed modules are designed with universal interfaces and standardized configurations that can accommodate different cell types and processing protocols. This multi-functionality enables the automated system to handle various therapeutic applications while maintaining closed-system integrity, thereby reducing contamination risk across different manufacturing scenarios.
2Reliability
If highly automated systems are implemented, then contamination risk is reduced, but system cost increases and flexibility decreases
Solution Approach 1:
By segmenting the system into discrete closed modules, the complexity is distributed rather than concentrated. Each module can be manufactured, validated, and maintained independently, reducing overall system cost while maintaining automated processing benefits that lower contamination risk.
Solution Approach 2:
The system employs disposable closed modules that are pre-sterilized and single-use. This approach eliminates the need for expensive sterilization infrastructure and complex cleaning validation, reducing system cost while maintaining closed-system integrity and low contamination risk throughout the manufacturing process.
3Productivity
If sequential processing is used, then process simplicity is maintained, but productivity decreases due to workflow bottlenecks
Solution Approach 1:
The manufacturing process is segmented into independent closed modules that can operate in parallel. Multiple enrichment modules, expansion modules, or harvesting modules can be connected to the automated system simultaneously, enabling concurrent processing of multiple samples and eliminating sequential bottlenecks while maintaining manageable system complexity through modular architecture.
4Manufacturing precision
If custom equipment is designed for specific processes, then process optimization is achieved, but adaptability to different customers and protocols is reduced
Solution Approach 1:
The closed modules are designed with universal features and standardized interfaces that can accommodate different cell types, viral vectors, and processing protocols. The automated system can be configured to support various customer-specific processes through software programming and module arrangement rather than custom hardware design, maintaining both optimization and adaptability.
Solution Approach 2:
The system employs dynamic configuration capabilities where the arrangement and connection of closed modules can be adjusted based on specific processing requirements. This dynamic adaptability allows the same modular hardware platform to be optimized for different protocols and customer needs without requiring custom equipment design.
