Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cisplatin is used as an anti-tumor drug, then broad-spectrum anti-tumor activity is achieved, but severe toxicity and drug resistance occur
Solution Approach 1:
The patent modifies the chemical structure of cisplatin by replacing the platinum center with organic compounds containing nitrogen-containing polycyclic aromatic rings, altering the fundamental parameters of the drug molecule to achieve similar anti-tumor activity with reduced toxicity
Solution Approach 2:
The invention creates composite organic molecules combining multiple polycyclic aromatic rings with nitrogen atoms, forming a complex structure that mimics the therapeutic effect of cisplatin while avoiding its toxic side effects through different chemical composition
2Reliability
If cisplatin is used to treat advanced tumors, then broad-spectrum efficacy is achieved, but drug resistance develops
Solution Approach 1:
By changing the core metal center to organic nitrogen-containing structures, the patent creates drugs with different mechanisms of action that can overcome resistance developed to traditional platinum-based therapies
3Object-affected harmful factors
If new anti-tumor drugs are developed to reduce toxicity, then safety is improved, but anti-tumor activity may be compromised
Solution Approach 1:
The patent introduces specific functional groups and substituents at particular positions on the polycyclic aromatic rings to optimize the balance between anti-tumor activity and toxicity, creating localized chemical features that enhance therapeutic selectivity
