Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional manufacturing processes are used, then cell therapy production can be performed with existing equipment, but cell loss is high (up to 92.1% T-cell loss) and production time is prolonged
Solution Approach 1:
The patent combines multiple cell processing functions (separation, washing, concentration, genetic modification) into a single integrated centrifuge system with a unified rotor that can perform sequential operations without transferring cells between different equipment, thereby reducing cell loss and shortening production time
Solution Approach 2:
The centrifuge system enables continuous processing where cells remain in the same vessel throughout multiple processing steps, eliminating interruption and transfer between equipment, thus maintaining continuous useful action and reducing both cell loss and production time
2Adaptability or versatility
If traditional bead-based magnetic separation systems are used, then cell selection can be performed, but the systems are inefficient and lack flexibility for sequential selections
Solution Approach 1:
The patent employs dynamic magnetic field generation through electromagnetic coils that can be activated and deactivated programmatically, allowing flexible sequential selection of different cell populations based on various markers without physical reconfiguration, thereby achieving both high efficiency and adaptability
Solution Approach 2:
The patent replaces traditional mechanical bead-based magnetic separation with an electromagnetic field-based system that uses programmable coil activation to achieve cell separation, providing greater flexibility and efficiency without mechanical constraints
3Manufacturing precision
If flow sorters are used for multi-parametric sorting, then high purity can be achieved, but throughput is low and not suitable for clinical-scale production
Solution Approach 1:
The patent integrates acoustic field-based cell separation with pneumatic control systems that enable high-throughput processing while maintaining sorting precision, allowing clinical-scale production volumes to be processed efficiently
4Ease of operation
If multiple different antiquated equipment are used for cell processing, then various processing steps can be performed, but the processes are labor-intensive and prone to contamination
Solution Approach 1:
The patent combines multiple cell processing functions (separation, washing, concentration, genetic modification) into a single integrated centrifuge system with a unified rotor that can perform sequential operations without transferring cells between different equipment, thereby reducing cell loss and shortening production time
Solution Approach 2:
The system enables automated sequential processing where the centrifuge performs multiple operations automatically through programmable control, reducing manual intervention and associated contamination risks
