Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operations are used in CAR T cell manufacturing, then flexibility in process customization is maintained, but contamination risk increases and productivity decreases
Solution Approach 1:
The manufacturing system is divided into separate closed modules (enrichment module, transduction module, expansion module, harvest module) that can be independently operated and sterilized. Each module performs specific functions with dedicated fluid lines and connections, minimizing the need for manual intervention while maintaining process flexibility through modular configuration.
2Reliability
If automated systems are implemented to reduce human touchpoints, then contamination risk decreases, but system complexity and cost increase
Solution Approach 1:
The closed modular system uses standardized interfaces and universal fluid line connections that can accommodate different cell types and process variations. The same basic module architecture serves multiple therapeutic applications, reducing overall system complexity while maintaining automated operation across diverse manufacturing scenarios.
3Productivity
If existing automated systems are used, then some human touchpoints are eliminated, but workflow bottlenecks and inflexibility remain
Solution Approach 1:
The system enables dynamic process configuration where modules can be selectively activated or deactivated based on specific manufacturing requirements. Fluid line connections and module operations can be adjusted through automated control systems to accommodate different cell types, scales, and process protocols without physical reconfiguration, providing both high productivity and adaptability.
4Productivity
If parallel processing is implemented, then productivity increases, but fluid line management complexity increases
Solution Approach 1:
The system uses identical replicated module designs for parallel processing, where each module contains duplicate fluid line configurations and connection points. This standardized copying approach allows multiple modules to operate simultaneously with consistent fluid management protocols, reducing the complexity burden that would arise from customizing each parallel line independently.
