Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extensive human handling is used in existing bioprocessing systems, then operational flexibility is maintained, but contamination risk increases and automation extent decreases
Solution Approach 1:
The bioprocessing system is divided into multiple independent modules (cell enrichment module, activation module, genetic modification module, expansion module) that can be connected via standardized interfaces. This segmentation enables automated fluid management between modules while minimizing human intervention points, thus reducing contamination risk without sacrificing operational flexibility.
Solution Approach 2:
Automated fluid management systems act as intermediaries between modules, transferring cells and reagents without direct human contact. This intermediary mechanism reduces contamination risk by eliminating human handling while maintaining the ability to flexibly control process parameters through automated interfaces.
2Productivity
If distinct modules are used for cell enrichment, activation, genetic modification, and expansion, then productivity is enhanced through parallel processing, but device complexity increases
Solution Approach 1:
Each module is designed with standardized interfaces and can perform its specific function (enrichment, activation, genetic modification, or expansion) with multiple different cell types and protocols. This universality allows parallel processing of multiple cell products simultaneously, enhancing productivity while managing complexity through modular standardization.
Solution Approach 2:
By segmenting the bioprocessing system into distinct functional modules with standardized interfaces, the system enables parallel processing operations. Each module can operate independently and simultaneously, increasing overall productivity while the modular structure actually reduces complexity compared to a monolithic system by allowing independent optimization and maintenance of each module.
3Ease of operation
If automated fluid management is implemented, then ease of operation is improved through minimized human intervention, but device complexity increases
Solution Approach 1:
The automated fluid management system enables modules to self-regulate fluid transfer, mixing, and processing operations without human intervention. The system automatically manages reagent delivery, cell transfer, and process monitoring, improving ease of operation while the modular architecture keeps complexity manageable through standardized, interchangeable components.
Solution Approach 2:
Automated fluid management systems serve as intermediaries that handle complex fluid handling tasks between modules, improving ease of operation by eliminating manual intervention. The standardized interfaces and automated protocols simplify user interaction while the underlying complexity is encapsulated within the modular system architecture.
4Adaptability or versatility
If modular system architecture is used for parallel processing, then adaptability is enhanced for different cell therapy protocols, but device complexity increases
Solution Approach 1:
The modular architecture with standardized interfaces allows different module configurations to support various cell therapy protocols (CAR-T, TCR-T, NK cell therapy, etc.). Each module can be adapted to different protocols through standardized connections, enhancing versatility while managing complexity through modular standardization that allows independent optimization of each component.
