Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing fungicidal compounds are used, then basic fungicidal activity is provided, but biological activity and spectrum of activity are insufficient
Solution Approach 1:
The patent combines component (A) with various fungicides from different chemical classes (component B) to create mixed compositions that exhibit superior biological activity and broader spectrum of activity compared to individual compounds. The synergistic interactions between components enhance overall efficacy against phytopathogenic fungi.
Solution Approach 2:
The invention creates composite fungicidal compositions comprising component (A) and component (B) where the combination produces effects greater than the sum of individual components. These composite materials provide improved biological activity and expanded spectrum of activity through complementary modes of action.
2Reliability
If higher application rates are used to improve control efficacy, then biological activity increases, but environmental impact and operator exposure increase
Solution Approach 1:
The patent converts the potential harm of high application rates by using synergistic combinations that achieve superior control efficacy at reduced rates. The synergistic interaction between component (A) and component (B) allows lower total application rates while maintaining or improving efficacy, thereby reducing environmental impact and operator exposure.
Solution Approach 2:
The invention changes the parameter of application rate by utilizing compositions with synergistic interactions. The mixed compositions achieve enhanced control efficacy at lower application rates compared to individual compounds, thus reducing environmental burden while maintaining effectiveness.
3Adaptability or versatility
If multiple fungicidal compounds are combined to broaden spectrum of activity, then activity against diverse phytopathogens improves, but composition complexity increases
Solution Approach 1:
Component (A) is designed with broad-spectrum activity against multiple phytopathogenic fungi when combined with component (B). The composition provides universal protection across different fungal diseases through the synergistic interaction, achieving multi-functionality without requiring multiple separate applications.
4Reliability
If conventional fungicidal compositions are applied, then disease control is achieved, but crop tolerance and safety profile are insufficient
Solution Approach 1:
The patent changes the safety profile parameter by using synergistic combinations that provide effective disease control at reduced application rates. This reduction in dosage improves crop tolerance while maintaining control efficacy, and the specific formulation parameters enhance the safety profile of the composition.
