Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extensive human handling and complex operations are used in existing bioprocessing systems, then flexibility in process customization is maintained, but contamination risk increases and manufacturing efficiency decreases
Solution Approach 1:
The bioprocessing system is divided into multiple isolated modules (enrichment module, activation module, expansion module, harvesting module) that can be independently operated. Each module performs a specific function with dedicated equipment, minimizing cross-contamination risks while maintaining process flexibility through modular configuration.
Solution Approach 2:
The system incorporates automated cell processing capabilities where cells are automatically transferred between modules using closed systems and automated liquid handling. The modules self-regulate process parameters and maintain sterile barriers without requiring manual intervention, reducing contamination risk while preserving process customization through programmable control.
2Productivity
If multiple separate operations are performed sequentially in existing systems, then process control is maintained, but manufacturing time increases and productivity decreases
Solution Approach 1:
The system enables continuous cell processing by eliminating idle time between operations. Cells are continuously transferred from enrichment to activation to expansion to harvesting through automated conveyance systems. Media and reagents are continuously supplied, and processed materials are continuously removed, maintaining uninterrupted productive action throughout the manufacturing process.
Solution Approach 2:
Multiple processing operations that were previously performed sequentially in separate locations are merged into an integrated modular system where enrichment, activation, expansion, and harvesting occur in a coordinated sequence within the same facility. This consolidation eliminates transportation time and allows parallel processing of multiple cell types simultaneously.
3Reliability
If highly specialized equipment is used to automate the manufacturing process, then contamination risk decreases, but system cost increases and flexibility is reduced
Solution Approach 1:
The modular bioprocessing system uses standardized equipment configurations that can perform multiple functions across different modules. For example, automated liquid handlers are used for media addition, cell transfer, and reagent mixing in various modules. This universal equipment approach reduces overall system cost compared to specialized equipment for each operation while maintaining automated contamination control.
Solution Approach 2:
The system incorporates disposable sterile barriers and single-use bioreactors in each module that eliminate the need for expensive sterilization equipment and complex cleaning validation systems. These disposable components provide reliable contamination protection at lower cost by replacing expensive reusable equipment with affordable single-use alternatives.
4Adaptability or versatility
If existing systems require customers to adapt their processes to particular equipment, then equipment standardization is achieved, but process flexibility and adaptability are lost
Solution Approach 1:
The modular system features programmable control that allows process parameters, transfer rates, and operational sequences to be dynamically adjusted for different cell types and therapeutic protocols. Each module can be independently programmed to handle specific cell characteristics, enabling the system to adapt to various processes without requiring physical reconfiguration or customer process adaptation.
