Engineering Contradiction Analysis
1Reliability
If existing pest control chemicals are used, then pest control effect is achieved, but pest resistance to chemicals develops
Solution Approach 1:
The patent introduces a novel chemical compound with a specific molecular structure (Formula 1) that differs from existing pest control agents. By changing the chemical parameters - specifically using a pyridine ring combined with specific substituent groups (X, Y1-Y5, Q1-Q2) and amide linkages - the invention creates a new mode of action that overcomes resistance developed to conventional chemicals while maintaining effective pest control.
2Adaptability or versatility
If a novel pest control agent is developed, then broad-spectrum pesticidal effect is achieved, but complexity of compound structure increases
Solution Approach 1:
The patent describes a compound with a versatile molecular framework where the pyridine ring system (with A being C, O, N or oxidized N) can accommodate various substituent groups (X representing multiple functional groups, Y1-Y5 being H, F, Cl, Br, I or CF3, and Q1-Q2 being various aromatic or heterocyclic groups). This universal structure allows the single compound to interact with multiple pest targets and mechanisms, achieving broad-spectrum activity across different pest types while maintaining a consistent core structure.
