Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional methods (ultrafiltration, immobilization on beads, or fixed substrate) are used to recycle biocatalysts in continuous manufacturing, then biocatalyst retention is achieved, but the methods are not amenable to solids-forming reactions and have limited scalability
Solution Approach 1:
The patent replaces conventional mechanical separation methods (ultrafiltration, bead filtration) with magnetic field-based separation. Magnetic beads functionalized with biocatalysts can be easily separated from reaction mixtures using external magnets, enabling continuous processing and making the system amenable to solids-forming reactions while improving scalability
2Productivity
If magnetic separation is used to separate magnetic and non-magnetic solids in continuous manufacturing, then scalability and efficiency are improved, but the device complexity increases
Solution Approach 1:
The separation device is segmented into distinct functional zones: a reaction chamber where biocatalytic reactions occur, and a separation chamber where magnetic separation takes place. This segmentation allows continuous flow processing while simplifying the overall device structure by concentrating magnetic separation components in a dedicated zone
Solution Approach 2:
The magnetic beads serve multiple functions: they provide a support matrix for biocatalyst immobilization, enable easy separation via magnetic fields, and can be reused across multiple reaction cycles. This multi-functionality reduces the need for additional components, thereby simplifying the device structure while maintaining continuous manufacturing efficiency
