Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If centralized production is used for polynucleotide therapeutics, then manufacturing scale is improved, but contamination risk and degradation increase
Solution Approach 1:
The patent divides the manufacturing system into distributed microfluidic production units that can operate independently at point-of-care locations, eliminating the need for large centralized facilities while maintaining production capability through multiple small-scale units
Solution Approach 2:
The patent introduces microfluidic devices as intermediary platforms that enable direct local production of polynucleotide therapeutics, serving as a bridge between centralized design and decentralized manufacturing to reduce contamination risks associated with traditional centralized production
2Measurement precision
If dynamic light scattering assembly is integrated into microfluidic system, then particle size measurement capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the dynamic light scattering assembly with the microfluidic system into an integrated device, merging particle characterization capabilities directly into the production platform to enable real-time monitoring without requiring separate complex measurement systems
Solution Approach 2:
The microfluidic device is designed to perform multiple functions including mixing, reaction, and particle size measurement through the integrated dynamic light scattering assembly, allowing a single device to handle both production and characterization tasks

Implementation Method 1
The first optical fiber is to emit light. The first port is to direct the light emitted by the first optical fiber through the optically transmissive material and into the fluid chamber.
Implementation Method 2
The second optical fiber is to receive light scattered by particles in fluid in the fluid chamber in response to the first optical fiber emitting light into the fluid chamber.
