Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If qPCR process is used to detect genetic material, then detection accuracy is improved, but device complexity and portability are worsened due to requirement of stationary thermal cycler
Solution Approach 1:
The patent divides the complex qPCR system into modular components: sample collection module, filtration module, extraction module, amplification module, and detection module. Each module performs a specific function, allowing the system to be deployed in field conditions while maintaining detection accuracy. The modular design enables portability without sacrificing the analytical capabilities of traditional qPCR.
Solution Approach 2:
The patent introduces intermediate processing steps including filtration through specific membrane filters and genetic material extraction using chemical reagents. These intermediary steps prepare the sample for detection in a portable format, bridging the gap between field collection and laboratory-grade analysis. The filtration and extraction processes enable accurate detection without requiring the sample to be processed in a traditional laboratory setting.
2Reliability
If manual sample collection and laboratory processing is used, then detection reliability is improved, but time consumption is worsened
Solution Approach 1:
The patent incorporates preliminary actions at the field site including sample filtration through pre-prepared membrane filters and on-site extraction using portable equipment. By performing these preparatory steps in the field rather than transporting raw samples to the laboratory, the system reduces total processing time while maintaining reliability through controlled extraction and detection processes.
Solution Approach 2:
The patent enables continuous processing from sample collection through detection in an uninterrupted workflow. The portable system allows each stage (filtration, extraction, amplification, detection) to be performed sequentially without breaking the chain of custody or requiring sample transport, thereby reducing time loss while maintaining detection reliability through continuous controlled processing.
3Adaptability or versatility
If field deployment is implemented, then operational flexibility is improved, but detection precision is worsened due to environmental conditions
Solution Approach 1:
The patent employs dynamic control elements including temperature-controlled amplification chambers with programmable heating elements and real-time monitoring of reaction conditions. These dynamic controls allow the system to adapt to varying environmental conditions in the field while maintaining precise detection by actively regulating critical parameters such as temperature and reaction time throughout the amplification and detection processes.
4Productivity
If integrated portable system is used, then productivity is improved, but device complexity is worsened
Solution Approach 1:
The patent merges multiple previously separate functions (filtration, extraction, amplification, detection) into a single integrated portable device. This consolidation enables continuous processing of samples through all stages without external intervention, significantly improving productivity. The merged system uses shared components such as microfluidic channels, integrated heating elements, and unified control electronics to manage complexity while maintaining high throughput capability.

AI summary
This disclosure describes techniques for detecting genetic material in a sample using a fluidic reactor device. The fluidic reactor device may receive a fluid containing genetic material to be processed through a filter component. The fluidic reactor device may react an enzyme with the fluid at a first component to expel genetic material from the filter component. The fluidic reactor device may also react another enzyme with the genetic material in order to generate extracellular genetic material, which may be amplified. CRISPR-Cas13 techniques may be performed by the fluidic reactor device on the amplified genetic material in order to generate fluorescence based on the presence of the amplified extracellular genetic material.
