Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If new fungicidal compounds and compositions are developed to achieve superior biological properties, then biological activity and spectrum of activity are improved, but development complexity and cost increase
Solution Approach 1:
The patent combines compound (A) from formula (I) with compound (B) having a different mode of action in a mixture composition. This merging of two distinct fungicidal compounds with different mechanisms of action achieves superior biological activity and broader spectrum of activity while managing the complexity through defined weight ratios and formulation strategies.
Solution Approach 2:
The invention creates a composite fungicidal composition comprising compound (A) of formula (I) and compound (B) with different modes of action. This composite approach leverages the synergistic interactions between the two compounds to achieve enhanced efficacy, improved crop tolerance, and broader spectrum of activity compared to single compounds.
2Reliability
If fungicidal compositions are applied frequently to maintain effective control, then disease control is improved, but operator exposure and environmental impact increase
Solution Approach 1:
The patent formulates compositions with optimized weight ratios of compound (A) to compound (B) ranging from 20:1 to 1:40, allowing dynamic adjustment based on specific disease pressure, crop stage, and environmental conditions. This enables effective disease control while minimizing application frequency and reducing operator exposure and environmental impact.
Solution Approach 2:
The invention changes the parameters of the fungicidal composition by combining compounds with different modes of action in specific proportions, thereby achieving longer-lasting residual activity and more rapid onset of action. This reduces the number of applications required, thereby reducing operator exposure and environmental impact.
3Reliability
If higher application rates are used to ensure effective fungicide coverage, then disease control is improved, but crop tolerance may be reduced and environmental impact increases
Solution Approach 1:
The patent optimizes the weight ratio parameters of compound (A) to compound (B) in the composition, achieving effective disease control at reduced application rates. The synergistic interaction between the two compounds with different modes of action enhances efficacy while improving crop tolerance and reducing environmental impact.
Solution Approach 2:
The composite composition of compound (A) and compound (B) with different modes of action provides superior biological activity and broader spectrum of activity, enabling effective disease control at lower application rates. This composite approach improves crop tolerance while maintaining or enhancing disease control efficacy.
