Engineering Contradiction Analysis
1Productivity
If batch processing is used for solid phase synthesis, then reactions can be performed with simple solvent washes, but the process is inefficient, unpredictable, and costly
Solution Approach 1:
The reaction system is segmented into discrete functional zones (reaction zone, rinsing zone, drying zone) along the elongate material path, allowing each zone to perform a specific function continuously. This segmentation enables efficient processing while maintaining operational simplicity through modular zone design.
Solution Approach 2:
The system transforms batch processing into continuous processing by moving the elongate material through multiple zones where reactions, rinsing, and drying occur continuously. This eliminates idle time between batches and maintains constant productive action, significantly improving reaction efficiency and predictability.
2Area of moving object
If resin beads are used as insoluble material, then reactions can occur on the solid phase, but the surface area to volume ratio is limited
Solution Approach 1:
The system transitions from three-dimensional resin beads to a two-dimensional elongate material (ribbon or tape) configuration. This dimensional change dramatically increases the surface area to volume ratio, providing greater reaction surface area while minimizing material volume, thereby improving reaction efficiency and reagent contact.
3Productivity
If continuous processing is implemented, then efficiency and predictability improve, but a viable method has not yet been proposed
Solution Approach 1:
The elongate material is pre-prepared with attached starting species and linker groups before entering the continuous processing system. This preliminary preparation allows the continuous processor to focus solely on the reaction and purification steps, simplifying the implementation of continuous processing while achieving high efficiency and predictability.
Solution Approach 2:
The system enables easy optimization by allowing parameters such as residence time, temperature, and reagent flow rates to be adjusted independently in different zones. This parameter flexibility simplifies the implementation of continuous processing by allowing rapid optimization without redesigning the entire system.
