Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If proteins are immobilized on solid matrices for detection, then detection capability is improved, but protein denaturation occurs
Solution Approach 1:
The patent uses nucleic acid amplification products as an intermediary to detect protein expression indirectly. Instead of immobilizing proteins directly on the matrix (which causes denaturation), the system transcribes and amplifies nucleic acid sequences that correspond to the proteins of interest, then detects these amplified nucleic acids on the solid matrix. This intermediary approach allows detection without direct protein immobilization, preserving protein stability while maintaining detection capability.
2Productivity
If multiple RNA species are detected simultaneously, then analysis efficiency is improved, but detection complexity increases
Solution Approach 1:
The patent employs universal detection elements that can detect multiple different RNA species simultaneously. The solid matrix contains multiple detection probes that can bind to different target RNA sequences, and the system uses universal transcription and amplification mechanisms that work for all targets. This allows simultaneous detection of multiple RNA species through a unified platform, improving analysis efficiency while managing complexity through standardization.
Solution Approach 2:
The detection system divides the analysis into separate functional modules: hybridization of detection probes to target RNAs, transcription amplification, and signal detection. Each module handles specific tasks independently, allowing simultaneous processing of multiple RNA species while maintaining organized complexity. The segmentation enables parallel processing without overwhelming system complexity.
3Illumination intensity
If complex amplification processes are used, then signal strength is improved, but process complexity increases
Solution Approach 1:
The patent employs self-service amplification mechanisms where the system uses its own components to amplify signals. The detected RNA targets serve as templates for transcription amplification, generating multiple copies that enhance the signal. The amplified products then serve as templates for further amplification cycles. This self-amplifying approach strengthens signals while reducing the need for external complex amplification machinery, as the system uses its detected targets to drive the amplification process.
