Engineering Contradiction Analysis
1Reliability
If existing compounds are used for controlling harmful arthropods, then some pest control effect is achieved, but the efficacy is insufficient and lacks specificity
Solution Approach 1:
The patent applies parameter changes by systematically varying the heterocyclic core structure (different ring sizes, nitrogen atom positions), substituent types (halogens, alkyl groups, functional groups), and molecular configurations to optimize both efficacy and specificity. This involves changing chemical parameters such as molecular weight, polarity, and steric arrangement to achieve superior pest control performance while maintaining selectivity
Solution Approach 2:
The invention creates composite molecular structures by combining heterocyclic cores with diverse substituent groups (aryl, heteroaryl, alkyl, functional groups). These composite structures integrate multiple functional elements within a single molecule, enabling enhanced interaction with pest biological targets while improving both control efficacy and specificity simultaneously
