Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agrochemical formulations, particularly granular formulations containing chlorantraniliprole, face challenges in achieving quick and efficient release of active ingredients, leading to inadequate pest control and potential environmental concerns due to excessive active ingredient amounts and resistance issues.
Innovation Solution
A quick release insecticidal composition comprising a diamide insecticide like chlorantraniliprole, dispersed in a carrier matrix comprising a binder and a surfactant, which facilitates rapid release upon contact with water, ensuring effective pest control with controlled active ingredient distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If active ingredients are formulated with inert ingredients in granular formulations, then the desired dosage form and characteristics are obtained, but the active ingredients are not released to their full extent in the required time
Solution Approach 1:
The patent changes the chemical and physical parameters of the carrier matrix by incorporating specific surfactants (anionic, cationic, nonionic, or amphoteric) and binders in optimized ratios. This modifies the matrix properties to enable rapid dissolution and release of chlorantraniliprole, achieving over 60% release within 1 hour while maintaining formulation stability and pest control effectiveness
Solution Approach 2:
The patent creates a composite carrier matrix system combining multiple components: binders (natural or synthetic polymers), surfactants (various types), and inert ingredients. This composite structure facilitates both the mechanical integrity of granules and the rapid release of active ingredient through synergistic interactions among components
2Reliability
If greater amounts of active ingredient are used, then pest control is improved, but environmental leaching risk and economic cost increase
Solution Approach 1:
The patent designs a controlled release system where the carrier matrix continuously releases active ingredient over time, maintaining effective concentrations at the pest site. This continuous release mechanism ensures sustained pest control with smaller total amounts of active ingredient, reducing environmental leaching while maintaining reliability
Solution Approach 2:
The carrier matrix acts as an intermediary between the active ingredient and the environment, controlling the release kinetics and preventing premature leaching. The matrix components (binders, surfactants) mediate the release process, ensuring active ingredient is delivered efficiently to target pests rather than leaching into environment
3Object-affected harmful factors
If smaller amounts of active ingredient are used, then environmental and economic concerns are reduced, but pest control effectiveness decreases and resistance risk increases
Solution Approach 1:
The patent optimizes formulation parameters including surfactant concentration (0.1-30% w/w), binder ratio (1:5 to 5:1), and active ingredient content (0.1-70% w/w) to maximize release efficiency. These parameter changes enable smaller amounts of active ingredient to achieve equivalent pest control by improving bioavailability and release kinetics
4Ease of operation
If chlorantraniliprole is formulated in water-based granular system, then ease of application is improved, but the poor water solubility of chlorantraniliprole makes ready availability difficult
Solution Approach 1:
The patent uses surfactants as intermediary substances that bridge the hydrophobic chlorantraniliprole and the aqueous environment. These surfactants form micelles or complexes with the active ingredient, enabling its dissolution and dispersion in water-based granular formulations while maintaining rapid release capability
Solution Approach 2:
The patent modifies the solubility parameters of chlorantraniliprole by incorporating surfactants that change the physical-chemical environment. The surfactant molecules interact with the hydrophobic active ingredient, effectively increasing its apparent water solubility and enabling ready availability in water-based systems
