Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current fungicides are not universally effective against various fungal pathogens and often require multiple applications, which can increase costs and complexity in agricultural use.

Innovation Solution

Development of picolinamide compounds, specifically formulated as fungicides that can protect plants against ascomycetes, basidiomycetes, deuteromycetes, and oomycetes, applied in various formulations such as solutions, dusts, or granules to provide broad-spectrum fungal protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple different fungicides are used to target different fungal pathogens, then the coverage of fungal protection is improved, but the complexity of application and cost increase

Engineering Contradiction:

Improvecoverage of fungal protectionVSAvoidcomplexity of application

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The picolinamide compound is designed to provide broad-spectrum fungicidal activity against multiple fungal groups (ascomycetes, basidiomycetes, deuteromycetes, and oomycetes) through a single active ingredient, eliminating the need to apply multiple specialized fungicides while maintaining effective protection coverage

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple different fungicides are used to target different fungal pathogens, then the coverage of fungal protection is improved, but the cost of application increases

Engineering Contradiction:

Improvecoverage of fungal protectionVSAvoidcost of application

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

A single picolinamide compound replaces multiple fungicide products, reducing the total quantity of chemical substances required for application while achieving comparable or superior broad-spectrum protection, thereby lowering overall application costs

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Duration of action of stationary object

If multiple applications of fungicides are made to maintain protection, then the duration of protection is improved, but the loss of time and increased operational complexity occur

Engineering Contradiction:

Improveduration of protectionVSAvoidtime for application

Core Design Contradiction:

Duration of action of stationary objectVSLoss of time

Solution Approach 1:

The picolinamide compound provides sustained fungicidal protection over an extended period through its persistent mode of action, reducing the frequency of re-application needed while maintaining continuous protection coverage, thereby minimizing time loss and operational interruptions

Inventive Principle:

Principle #20Continuity of useful action
