Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insecticide formulations with adjuvants are physically unstable, leading to phase separation and high viscosity, which complicates storage, dosing, and application, and results in inaccurate concentration application.
Innovation Solution
A stable insecticide formulation comprising ketoenol insecticides, adjuvants, steric and/or static stabilizers, and rheomodifiers, which maintains physical and chemical stability for long-term storage and allows for easy dilution before use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insecticides and adjuvants are combined into stock formulations, then efficiency is improved, but physical stability deteriorates (phase separation occurs)
Solution Approach 1:
The patent introduces specific intermediaries (compatibilizers, surfactants, or polymers) that mediate between the insecticide active ingredient and adjuvant components. These intermediaries act as molecular bridges that prevent phase separation by reducing interfacial tension and promoting homogeneous distribution of all components in the stock formulation, thereby maintaining both efficiency and stability.
Solution Approach 2:
The patent creates a composite formulation system where multiple components (insecticide, adjuvants, stabilizers, and compatibility agents) are combined into a single integrated product. This composite approach allows the formulation to exhibit enhanced properties that individual components alone cannot provide, specifically maintaining physical stability while preserving the synergistic efficiency of insecticide-adjuvant combinations.
2Reliability
If stock formulations include both insecticides and adjuvants, then application efficiency is improved, but viscosity increases (impeding manufacturing and application)
Solution Approach 1:
The patent modifies key formulation parameters including the selection of adjuvant types (preferring lower-viscosity carriers), optimization of component concentration ratios, and adjustment of pH and ionic strength. These parameter changes enable the stock formulation to maintain reduced viscosity despite containing both insecticides and adjuvants, facilitating ease of manufacturing, dosing, and application while preserving application efficiency.
3Loss of time
If insecticides and adjuvants are pre-mixed in stock formulations, then field preparation time is reduced, but concentration accuracy deteriorates (under- or over-application)
Solution Approach 1:
The patent performs preliminary actions during formulation manufacturing by pre-calculating and pre-mixing exact concentrations of insecticides and adjuvants in precise ratios. Compatibility agents and stabilizers are added in advance to lock in the desired concentration relationships. This preliminary precision work ensures that when farmers simply dilute the stock formulation in the field, the final application concentration remains accurate, eliminating both time loss and concentration errors.
4Reliability
If adjuvants are added to insecticide formulations, then insecticidal activity is enhanced, but physical stability deteriorates (phase separation)
Solution Approach 1:
The patent employs compatibility agents and surfactants as intermediaries that specifically interact with adjuvant molecules to prevent them from causing phase separation. These intermediaries bind to adjuvants or reduce their interfacial activity, allowing the adjuvants to maintain their insecticidal enhancement function while their destabilizing effect is neutralized, thus preserving both enhanced activity and formulation stability.
