Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pest control chemicals often lack sufficient activity against pests, and there is a need for more effective compounds that can be used as agents for controlling pests in agricultural settings.
Innovation Solution
Development of tetrazolinone compounds with specific structural variations, represented by formula (1), which are applied as pest control agents to plants or soil to exert excellent control activity against pests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing pest control chemicals are used, then pest control is provided, but the control activity is insufficient
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of tetrazolinone compounds through systematic variation of substituent groups (R1-R6) at different positions on the phenyl rings. This structural optimization enhances the biological activity and pest control effectiveness of the compounds, directly addressing the insufficient control activity of existing chemicals.
2Reliability
If tetrazolinone compounds with specific structural variations are developed, then excellent control activity against pests is achieved, but compound complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the tetrazolinone compound into distinct functional modules: the core tetrazolinone ring, substituted phenyl groups, and various substituent patterns (R1-R6). This modular structural approach allows systematic optimization of pest control activity while maintaining clarity in the compound's architectural organization.
Solution Approach 2:
The patent applies local quality by introducing specific substituent groups at particular positions (R1-R6) on the phenyl rings to enhance pest control activity at specific molecular interaction sites. Different substituents (halogens, alkyl groups, alkoxy groups, cyano, nitro) are strategically placed to optimize local electronic and steric properties for maximum biological effectiveness.
