Solution Overview

Problem

Existing insecticides with active ingredients like spinetoram and cyclic keto-enol compounds with acetyl CoA carboxylase-inhibiting activity do not consistently demonstrate sufficient insecticidal efficacy, necessitating a composition that enhances pest control effectiveness.

Innovation Solution

A synergistic pest controlling composition combining spinetoram with cyclic keto-enol compounds such as spirotetramat, spirodiclofen, or spiromesifen, applied in various formulations, offering a weight ratio of spinetoram to cyclic keto-enol compounds ranging from 100:1 to 1:800 for enhanced pest control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If single active ingredients of insecticides (spinetoram or cyclic keto-enol compounds) are used, then the formulation is simple, but the insecticidal effect is insufficient

Engineering Contradiction:

Improveformulation complexityVSAvoidinsecticidal effect

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent combines spinetoram (a sodium channel modulator) with cyclic keto-enol compounds (acetyl CoA carboxylase inhibitors) to create a synergistic mixture that achieves superior insecticidal effect compared to single ingredients, resolving the contradiction between formulation simplicity and effectiveness

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If higher concentrations of single insecticide ingredients are applied to achieve sufficient effect, then the insecticidal effect improves, but the risk of pest resistance and phytotoxicity increases

Engineering Contradiction:

Improveinsecticidal effectVSAvoidphytotoxicity and resistance risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical mechanism parameters by combining two insecticides with different modes of action (sodium channel modulation and acetyl CoA carboxylase inhibition), enabling effective pest control at lower concentrations that reduce phytotoxicity and resistance development risks

Inventive Principle:

Principle #35Parameter changes
