Solution Overview

Problem

Current amide compounds are not effective in providing a superior control effect against arthropod pests, necessitating the development of a more potent compound for pest control.

Innovation Solution

An amide compound represented by formula (I), where R1 can be a hydrogen or halogen atom, and m and n represent specific values, is synthesized and used as an arthropod pest control agent, either alone or in combination with an inert carrier, to effectively control arthropod pests.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional amide compounds are used for arthropod pest control, then the control effect is insufficient, but developing new compounds increases research and development complexity

Engineering Contradiction:
Improvecontrol effect on arthropod pestsVSAvoidcompound structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by modifying the molecular structure of amide compounds through systematic variation of R1 substituents (hydrogen or halogen atoms) and positional parameters (m=1 or 2, n=0 or 1). This structural parameter optimization enhances the control effect on arthropod pests while maintaining reasonable molecular complexity, directly resolving the contradiction between effectiveness and complexity.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If existing amide compounds are applied to arthropod pests, then the knockdown rate is low, but increasing compound potency may increase toxicity and safety concerns

Engineering Contradiction:
Improveknockdown rate of pestsVSAvoidtoxicity to non-target organisms
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by introducing specific substituent patterns at particular positions in the amide compound structure. The R1 group (hydrogen or halogen) at specific positions provides enhanced pest control activity through localized molecular interactions, achieving high knockdown rates while the overall molecular design maintains selective toxicity, thus resolving the contradiction between productivity and safety.

Inventive Principle:
Principle #3Local quality
