Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional diagnostic and therapeutic approaches are used for cancer and diseases involving microvesicles, then treatment can be provided, but specificity and efficiency in detecting biomarkers and targeting microvesicle surface antigens is insufficient
Solution Approach 1:
The patent uses oligonucleotide aptamers as synthetic copies that replicate the binding function of natural ligands for microvesicle surface antigens. These aptamers are selected from libraries to specifically bind to target antigens, providing a customizable and highly specific diagnostic and therapeutic tool that overcomes the limitations of conventional approaches
Solution Approach 2:
The patent employs systematic variation of oligonucleotide sequences and structures to optimize binding affinity and specificity for microvesicle surface antigens. By changing parameters such as nucleotide composition, length, and chemical modifications, the aptamers achieve enhanced detection precision and therapeutic effectiveness
2Measurement precision
If oligonucleotide aptamers are developed to bind specifically to microvesicle surface antigens, then diagnostic and therapeutic specificity is improved, but development complexity and screening requirements increase
Solution Approach 1:
The patent utilizes in vitro selection methods where oligonucleotide libraries automatically select and bind to their target microvesicle surface antigens without extensive manual intervention. The selection process allows the aptamers to self-organize and identify specific binders, reducing development complexity while maintaining high binding specificity
Solution Approach 2:
The patent develops oligonucleotide aptamers that can serve multiple functions including diagnostic detection, therapeutic targeting, and research applications. This multi-functionality reduces the need for separate development programs for different applications, thereby managing complexity while providing versatile tools
