Solution Overview

Problem

Existing compounds of formula (I) used for controlling animal pests have insufficient efficacy, spectrum of activity, and plant compatibility, especially when combined with other insecticides and/or acaricides.

Innovation Solution

Combinations of compounds of formula (I) with specific mixing partners (B-1) to (B-5) in synergistically effective amounts and weight ratios, enhancing insecticidal, nematicidal, and/or acaricidal effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If compounds of formula (I) are used for controlling animal pests, then pest control function is provided, but efficacy and spectrum of activity are insufficient

Engineering Contradiction:

ImproveefficacyVSAvoidspectrum of activity

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent combines compounds of formula (I) with other insecticides and/or acaricides to create mixture formulations. This merging of different active ingredients expands the spectrum of activity against various pests while maintaining or enhancing the overall efficacy through synergistic effects.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention creates composite pesticide formulations by combining compounds of formula (I) with other insecticidal and acaricidal agents. These composite materials leverage the complementary properties of each component to achieve broader pest coverage and improved effectiveness.

Inventive Principle:

Principle #40Composite materials

2Reliability

If compounds of formula (I) are used for controlling animal pests, then pest control function is provided, but plant compatibility is insufficient

Engineering Contradiction:

Improvepest control functionVSAvoidplant compatibility

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent modifies the chemical structure of compounds of formula (I) by varying substituents (W, X, Y, A, B, G, D) to optimize the balance between pest control efficacy and plant compatibility. Different substituent combinations are explored to reduce phytotoxicity while maintaining insecticidal and acaricidal activity.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The use of mixture formulations acts as an intermediary approach, where compounds of formula (I) are combined with other insecticides and acaricides in specific ratios. This intermediary formulation reduces the individual dosage of each compound, thereby minimizing plant damage while maintaining effective pest control.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If compounds of formula (I) are mixed with other insecticides and/or acaricides, then spectrum of activity is expanded, but synergistic effect is not achieved

Engineering Contradiction:

Improvespectrum of activityVSAvoidsynergistic effect

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent optimizes the concentration ratios of compounds of formula (I) to other insecticides and acaricides in the mixture formulations. By carefully adjusting these parameters, the invention achieves synergistic effects where the combined activity exceeds the sum of individual components, while simultaneously expanding the spectrum of activity.

Inventive Principle:

Principle #35Parameter changes
