Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current treatments for pathological conditions involving FGFs are used, then existing therapeutic options are available, but effective inhibitors that can specifically target the binding of FGFs to their receptors are lacking
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of indolizine derivatives through systematic variation of substituents at different positions (R1-R8 groups). This structural optimization enables the compounds to achieve both high therapeutic effectiveness and specific targeting capability by fine-tuning molecular parameters such as binding affinity and selectivity for FGF receptors
Solution Approach 2:
The patent employs composite material principles by creating complex indolizine derivative molecules with multiple functional groups and substituted moieties. These composite molecular structures combine different chemical features (heteroatoms, aromatic rings, aliphatic chains) to achieve simultaneous inhibition of FGF binding and specific receptor targeting, resolving the contradiction between effectiveness and adaptability
2Reliability
If novel indolizine derivatives are developed to specifically inhibit FGF binding, then targeted therapeutic approach is achieved, but synthesis complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the synthesis of complex indolizine derivatives into multiple discrete steps involving separate preparation of substituted moieties, coupling reactions, and final assembly. This stepwise approach manages synthesis complexity while achieving the desired high inhibition efficacy through precise molecular construction
Solution Approach 2:
The patent employs preliminary action by pre-synthesizing and characterizing various substituted indolizine derivatives before final biological testing. This advance preparation allows optimization of synthesis routes and selection of most promising candidates, balancing the complexity of synthesis with the need for high inhibition efficacy
