Solution Overview

Problem

Existing insecticidal compositions comprising bifenthrin and chlorantraniliprole face challenges such as physical stability issues when diluted with water and unpredictable antagonism, leading to inadequate efficacy in controlling insect pests.

Innovation Solution

The development of insecticidal concentrate compositions comprising bifenthrin and chlorantraniliprole, with a weight ratio of 10:1 to 1:10, and concentrations of bifenthrin ranging from 10 wt.% to 60 wt.%, formulated as liquids, dispersions, suspensions, or emulsions, to enhance stability and efficacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional insecticidal compositions containing bifenthrin and chlorantraniliprole are combined, then the spectrum of pest control is broadened, but physical stability deteriorates due to phase separation when diluted in water

Engineering Contradiction:

Improvespectrum of pest controlVSAvoidphysical stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent modifies the chemical composition parameters by incorporating specific surfactants and adjuvants in optimized ratios. The formulation includes bifenthrin (1-10% w/v), chlorantraniliprole (1-10% w/v), and specific combinations of surfactants (anionic, nonionic, cationic) with controlled HLB values and concentrations, which change the physical-chemical parameters to prevent phase separation while maintaining broad-spectrum efficacy

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite insecticidal formulation by combining multiple active ingredients (bifenthrin and chlorantraniliprole) with carefully selected surfactant systems. This composite structure includes synergistic combinations of anionic surfactants (e.g., alkylbenzenesulfonates), nonionic surfactants (e.g., alkyl polyglycosides), and cationic surfactants (e.g., quaternary ammonium compounds) that work together to maintain physical stability while providing broad-spectrum pest control

Principle #40Composite materials

2Adaptability or versatility

If multiple insecticides are combined in traditional formulations, then the efficacy against different pest species is improved, but unpredictable antagonism occurs reducing overall efficacy

Engineering Contradiction:

Improvespectrum of pest controlVSAvoidefficacy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent incorporates feedback mechanisms through optimized formulation design where the interaction between bifenthrin (pyrethroid) and chlorantraniliprole (ryanodine receptor agonist) is carefully balanced. The specific ratio ranges and surfactant selections provide feedback control to prevent antagonistic interactions, ensuring reliable efficacy across different pest species while maintaining broad-spectrum activity

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent changes the concentration parameters of the active ingredients to optimal ranges (bifenthrin: 1-10% w/v, chlorantraniliprole: 1-10% w/v) and incorporates specific surfactant systems with controlled HLB values. These parameter modifications ensure synergistic or at least additive effects between the two insecticides, preventing unpredictable antagonism while maintaining broad-spectrum pest control efficacy
