Solution Overview

Problem

Current fungicidal compositions for controlling phytopathogenic fungi in agriculture lack superior biological activity, spectrum of activity, safety profile, and physico-chemical properties, requiring new compounds with enhanced efficacy and reduced environmental impact.

Innovation Solution

A fungicidal composition comprising a mixture of specific compounds, such as N-[(1,2 cis)-2-(2,4-dichlorophenyl)cyclobutyl]-2-(trifluoromethyl)pyridine-3-carboxamide and a cyanoacrylate compound, with varying weight ratios, offering broad-spectrum activity against phytopathogenic fungi and improved biodegradability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If new fungicidal compounds are developed to achieve superior biological activity and spectrum of activity, then crop protection efficacy is improved, but development complexity and cost increase

Engineering Contradiction:

Improvecrop protection efficacyVSAvoiddevelopment complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines two different fungicidal compounds with distinct modes of action into a single composition. Component (A) provides one mechanism of fungal control while component (B) provides a different mechanism, creating synergistic effects that enhance overall efficacy against a broader spectrum of phytopathogenic fungi without requiring complex development of single compounds

Inventive Principle:

Principle #5Merging (Combining)

2Object-affected harmful factors

If application rate is reduced to minimize environmental impact and operator exposure, then environmental safety is improved, but disease control efficacy may worsen

Engineering Contradiction:

Improveenvironmental impactVSAvoiddisease control efficacy

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent converts the potential harm of reduced application rates into a benefit by utilizing synergistic interactions between components (A) and (B). The combination achieves enhanced fungicidal activity at lower concentrations, where the synergistic effect compensates for the reduced dosage, maintaining disease control efficacy while minimizing environmental impact and operator exposure

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Adaptability or versatility

If broader spectrum of activity is achieved to control more phytopathogenic fungi, then versatility is improved, but selectivity and potential crop tolerance issues worsen

Engineering Contradiction:

Improvespectrum of activityVSAvoidcrop tolerance

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by using two compounds with different modes of action that target specific fungal pathways. Component (A) and component (B) each have specialized mechanisms that work together to provide broad-spectrum activity while maintaining selectivity. This allows the composition to effectively control diverse phytopathogenic fungi while reducing the risk of crop tolerance issues through targeted, multi-mechanism action

Inventive Principle:

Principle #3Local quality
