Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing antibiotics are used to treat bacterial infections, then treatment is effective against susceptible bacteria, but bacteria develop resistance leading to treatment failure
Solution Approach 1:
The patent employs parameter changes by modifying the chemical structure of carbapenem antibiotics through various substitutions at specific positions (R1, R2, R3, R4 groups) to create new derivatives with enhanced activity against resistant bacteria. The systematic variation of structural parameters allows optimization of both efficacy and resistance profiles
Solution Approach 2:
The invention creates composite molecular structures by combining the carbapenem core structure with diverse heterocyclic groups (oxa, thia, diaza rings) and substituent patterns. These composite structures exhibit synergistic properties that overcome bacterial resistance mechanisms while maintaining antibiotic activity
2Reliability
If new antibiotic compounds are developed to overcome resistance, then efficacy against resistant strains improves, but development complexity and time increase
Solution Approach 1:
The patent segments the antibiotic molecule into distinct functional modules: the carbapenem core, heterocyclic substituents (oxa, thia, diaza rings), and various R-group variations. This modular approach allows systematic exploration of structure-activity relationships while managing complexity through organized classification of derivatives
Solution Approach 2:
The invention creates a universal platform of carbapenem derivatives where a single core structure can generate multiple active compounds through systematic substitution. This multi-functional approach allows one parent compound to yield numerous derivatives with potentially different resistance profiles, reducing overall development complexity
