Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual library preparation and selection processes are used, then flexibility and adaptability are maintained, but time consumption increases and automation becomes difficult
Solution Approach 1:
The patent replaces manual mechanical library preparation processes with an automated microfluidic system that uses controlled fluid flow, pressure gradients, and integrated reagent delivery to perform library preparation steps automatically, eliminating manual intervention while maintaining protocol flexibility through programmable control
Solution Approach 2:
The microfluidic device integrates multiple functions including cell capture, lysis, library preparation, and sequencing operations within a single platform, allowing the system to perform diverse operations automatically without requiring separate manual procedures for each step
2Productivity
If high density platforms are used for cell capture, then capture efficiency is improved, but retrieval of target material becomes challenging
Solution Approach 1:
The patent segments the high-density captured cells into individual processing compartments or channels within the microfluidic device, allowing each captured cell or cell群体 to be retrieved and processed separately through controlled fluid flow, eliminating the retrieval challenges associated with maintaining high-density configurations
Solution Approach 2:
The microfluidic system introduces controlled fluid flow and pressure gradients as intermediary mechanisms to facilitate the retrieval of target material from high-density capture platforms, using these intermediaries to transport captured cells and released material through the system without direct manual manipulation
3Reliability
If extensive manual intervention is required, then process control and adaptability are maintained, but labor requirements and costs increase
Solution Approach 1:
The microfluidic device is designed to perform library preparation and processing operations autonomously using integrated reagent reservoirs, controlled fluidic networks, and automated mixing/incubation chambers that execute protocols without manual intervention, while maintaining reliable process control through embedded sensors and programmable flow control
Solution Approach 2:
The patent replaces manual mechanical operations with automated microfluidic control mechanisms including electrically controlled valves, pressure-driven flow systems, and integrated mixing chambers that provide consistent, repeatable process control without requiring manual labor
4Device complexity
If conventional sample processing methods are used, then simplicity is maintained, but signal-to-noise ratios and data quality deteriorate
Solution Approach 1:
The patent segments the sample processing into distinct microfluidic zones including capture regions, lysis chambers, and sequencing preparation areas, allowing each segment to be optimized for its specific function to maximize signal-to-noise ratio while maintaining overall system simplicity through modular design
Solution Approach 2:
The microfluidic device implements local quality optimization by providing different environmental conditions, reagent concentrations, and processing parameters in different regions of the device tailored to specific processing steps, thereby enhancing measurement precision and data quality without complicating the overall system architecture
