Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fluorescent dyes are used for nucleic acid detection, then the detection can be performed with existing methods, but the sensitivity and stability are insufficient for sophisticated diagnostic platforms
Solution Approach 1:
The patent modifies the chemical structure of fluorescent dyes by introducing specific substituents (R1-R6 groups) and heteroatoms (X=oxygen or sulfur) to alter photophysical properties. These parameter changes in molecular structure enhance quantum yield, stability, and sensitivity of the dyes for nucleic acid detection in sophisticated diagnostic platforms
Solution Approach 2:
The invention creates composite fluorescent dye molecules combining benzothiazole core structures with various aromatic substituents and heterocyclic groups. These composite molecular structures integrate multiple functional groups that work synergistically to improve both sensitivity and stability simultaneously
2Stability of the object's composition
If existing fluorescent dyes are used, then the diagnostic platform can operate with current technology, but the stability under accelerated conditions is inadequate
Solution Approach 1:
The patent introduces specific local chemical modifications at different positions (R1-R6 substituents) of the fluorescent dye molecule. Each substituent provides localized protection or electronic stabilization at critical positions, enhancing overall molecular stability under accelerated storage and assay conditions while maintaining detection reliability
