Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current fungicides used in agriculture face challenges in effectively controlling fungal diseases in crops without causing harm to the crops or the environment, and there is a need to address increasing fungal resistance.

Innovation Solution

The use of phthalimide fungicides, such as folpet and captan, applied in solid particulate form, either alone or suspended in an aqueous carrier, to treat crops against fungal pathogens, including specific fungal diseases like cercospora leaf spot and apple scab.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional fungicides are used to control fungal diseases in crops, then fungal disease control is achieved, but crop harm and environmental damage occur

Engineering Contradiction:

Improvefungal disease control effectivenessVSAvoidcrop harm and environmental damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the physical state parameter of fungicides from liquid to solid particulate form. This parameter change enables the fungicide to effectively control fungal diseases while reducing crop harm and environmental damage, as solid particulates have different absorption, distribution, and degradation characteristics compared to liquid formulations

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses composite material formulations by combining solid particulate fungicides with aqueous carriers. This composite approach allows the fungicide to maintain effectiveness against fungal diseases while the solid particulate nature reduces harmful effects on crops and the environment compared to conventional liquid fungicides

Inventive Principle:

Principle #40Composite materials

2Reliability

If fungicides are applied to control fungal diseases, then crop protection is improved, but fungicide用量 increases due to resistance development

Engineering Contradiction:

Improvecrop protection effectivenessVSAvoidfungicide用量

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent changes the physical state of fungicides to solid particulates, which appear to provide improved or sustained effectiveness against fungal pathogens. This parameter change may help overcome resistance issues and reduce the quantity of fungicide needed compared to conventional liquid formulations that fungi have developed resistance against

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If liquid fungicides are used for disease control, then application is easy, but environmental impact increases

Engineering Contradiction:

Improveapplication convenienceVSAvoidenvironmental impact

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent changes the physical state of fungicides from liquid to solid particulates suspended in aqueous carriers. This parameter change maintains ease of application through suspension formulations while solid particulates generate less environmental harm due to reduced runoff, leaching, and volatilization compared to liquid fungicides

Inventive Principle:

Principle #35Parameter changes
