Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural adjuvants often have negative impacts on the physico-chemical properties of agrochemical compositions, are harmful to soil and plants, and display biological activity, posing environmental and safety risks, while also being inefficient and costly.
Innovation Solution
An agricultural adjuvant comprising a polyphenol-containing natural or synthetic oil composition, anionic and nonionic surfactants, and a pH adjuster, which provides a stable, non-harmful, and environmentally friendly formulation with improved spreading and penetration characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional adjuvants are added to agrochemical compositions, then spreading and penetration performance is improved, but stability and solubility are compromised
Solution Approach 1:
The patent employs a composite adjuvant system comprising multiple surfactants (anionic, cationic, nonionic) and oils working synergistically. This composite approach allows the formulation to achieve both improved spreading/penetration and maintained stability, as each component compensates for the limitations of others while contributing specific functional properties
Solution Approach 2:
The patent optimizes specific parameter ranges including surfactant concentrations (0.1-10% w/v), oil content (5-50% w/v), and pH levels (4-9) to achieve the desired balance between spreading performance and composition stability. By carefully controlling these parameters, the adjuvant formulation maintains stability while delivering enhanced penetration and spreading effects
2Productivity
If adjuvants are added to tank mixes, then water usage and application time are reduced, but physico-chemical properties such as viscosity and particle size are negatively impacted
Solution Approach 1:
The patent controls viscosity within acceptable ranges (10-1000 cP) and maintains particle size below 10 micrometers through careful formulation parameter optimization. This allows the adjuvant to provide productivity benefits while preserving the physico-chemical properties necessary for effective agrochemical performance
3Ease of operation
If high terpene content adjuvants are used, then spreading performance is enhanced, but flashpoint decreases and safety risks increase
Solution Approach 1:
The patent combines multiple surfactant types and oils in a composite formulation that achieves effective spreading performance without relying solely on high terpene content. This diversified approach maintains flashpoint above 54°C and reduces flammability risks while preserving adjuvant functionality
Solution Approach 2:
The patent optimizes the terpene content within a balanced range (10-30% w/v) rather than using high concentrations, and adjusts other formulation parameters to achieve the desired spreading performance with improved safety margins
4Object-affected harmful factors
If surfactants are added to prevent active ingredient accumulation, then phytotoxicity is reduced, but foaming occurs which curbs spreading
Solution Approach 1:
The patent uses a composite surfactant system including anionic, cationic, and nonionic surfactants along with antifoaming agents and oils. This multi-component formulation prevents phytotoxicity through active ingredient dispersion while simultaneously controlling foam formation to maintain effective spreading performance
