Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing fungicidal compounds are used, then basic fungicidal activity is achieved, but the spectrum of activity is limited and crop tolerance is insufficient

Engineering Contradiction:

Improvespectrum of activityVSAvoidcrop tolerance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent combines component (A) cyclic depsipeptide and component (B) quinofumelin or related compound in a fungicidal composition. This merging of two different fungicidal compounds with distinct modes of action broadens the spectrum of activity against various phytopathogenic fungi while maintaining improved crop tolerance through synergistic interactions.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention creates a composite fungicidal composition comprising a mixture of component (A) and component (B) in specific weight ratios. This composite approach integrates compounds with different chemical structures and modes of action, achieving both broader fungal coverage and enhanced safety profile simultaneously.

Inventive Principle:

Principle #40Composite materials

2Duration of action of stationary object

If single fungicidal compounds are used, then application is simple, but residual activity is short and application frequency must be high

Engineering Contradiction:

Improveresidual activityVSAvoidapplication frequency

Core Design Contradiction:

Duration of action of stationary objectVSProductivity

Solution Approach 1:

The composition merges component (A) cyclic depsipeptide and component (B) quinofumelin or related compound, where component (B) specifically contributes longer lasting residual activity. This combination extends the protective duration, reducing the need for frequent applications and improving agricultural productivity.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If higher application rates are used, then fungicidal effectiveness is improved, but environmental impact and operator exposure increase

Engineering Contradiction:

Improvefungicidal effectivenessVSAvoidenvironmental impact

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention optimizes the weight ratio parameters of component (A) and component (B) to achieve effective fungicidal activity at reduced application rates. By carefully controlling the composition ratios, the patent maintains high effectiveness while minimizing environmental impact and operator exposure.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The composite composition leverages the complementary properties of component (A) and component (B) to achieve synergistic effects. This allows lower overall application rates to achieve the same or better effectiveness compared to single compounds, thereby reducing environmental burden.

Inventive Principle:

Principle #40Composite materials

4Adaptability or versatility

If fungicidal compositions with broader spectrum are developed, then activity against more fungi is achieved, but crop tolerance may be compromised

Engineering Contradiction:

Improvespectrum of activityVSAvoidcrop tolerance

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines component (A) cyclic depsipeptide and component (B) quinofumelin or related compound, which have different modes of action. This merging achieves broad-spectrum activity against multiple phytopathogenic fungi while the specific formulation maintains improved crop tolerance through synergistic interactions.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention optimizes the weight ratio parameters of the components to achieve the right balance between broad-spectrum efficacy and crop safety. By adjusting these parameters, the composition broadens fungal coverage without compromising crop tolerance.

Inventive Principle:

Principle #35Parameter changes
