Innovation Solution
A composition comprising a complex of a polycation and a bioactive ingredient, where the polycation and bioactive ingredient are mixed in specific ratios, forming a complex with enhanced biological efficacy, persistence, and rainfastness, and humectancy, which is then applied to plants to protect against phytopathogens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high amounts of pesticide are applied to ensure effectiveness, then the pest control efficacy is improved, but environmental contamination and adverse human health effects increase
Solution Approach 1:
The patent changes the physical and chemical parameters of the pesticide by forming a complex with a polycation. This complexation modifies the pesticide's properties including solubility, charge, and molecular size, enabling effective pest control at lower concentrations while reducing environmental harm
Solution Approach 2:
The patent creates a composite material by combining the pesticide (bioactive ingredient) with a polycation. This composite complex exhibits enhanced biological efficacy and persistence, allowing reduced application rates while maintaining or improving pest control effectiveness
2Ease of operation
If conventional pesticide formulations are used, then application is simple, but persistence and rainfastness on plant surfaces are limited
Solution Approach 1:
The polycation complexation changes surface properties of the pesticide formulation, enhancing adhesion to plant surfaces and resistance to rain washoff. The complexed pesticide demonstrates improved persistence while maintaining ease of application through standard spraying methods
3Duration of action of stationary object
If high amounts of pesticide are applied, then the duration of action is extended, but the amount of substance required increases
Solution Approach 1:
By complexing the pesticide with polycation, the formulation achieves extended duration of action through improved adhesion and reduced degradation. This parameter change allows achieving longer persistence with significantly reduced quantity of active ingredient
Solution Approach 2:
The composite polycation-pesticide complex provides prolonged protection against pests and diseases while requiring smaller amounts of bioactive ingredient, thereby extending duration of action without increasing substance quantity
