Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing herbicides, such as herbicide A, lack sufficient activity, spectrum of activity, compatibility with useful plants, and reliable control of unwanted plants, necessitating improved post-emergent weed control methods.

Innovation Solution

A composition comprising herbicide A, glufosinate, and optionally herbicide C, applied post-emergently, exhibits a synergistic effect, enhancing herbicidal activity against weeds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single herbicide A is used for weed control, then the application is simple, but the herbicidal activity and spectrum of activity are insufficient

Engineering Contradiction:

Improvecomposition complexityVSAvoidherbicidal activity

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent combines herbicide A with glufosinate (and optionally herbicide C) to create a multi-component composition. This merging of different herbicidal agents produces a synergistic effect that enhances overall herbicidal activity and broadens the spectrum of weed control, directly resolving the contradiction between simple application and sufficient efficacy.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If higher application rates of herbicide A are used to improve weed control, then herbicidal activity increases, but compatibility with useful plants decreases

Engineering Contradiction:

Improveweed control effectivenessVSAvoiddamage to useful plants

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the compositional parameters by introducing glufosinate and optionally herbicide C into the formulation. This parameter change allows for reduced application rates of the overall composition while maintaining or enhancing weed control effectiveness, thereby reducing phytotoxicity to useful plants through the synergistic interaction of components.

Inventive Principle:

Principle #35Parameter changes

3Quantity of substance

If herbicide A is used alone, then the application rate can be controlled, but the spectrum of activity against different weed species is limited

Engineering Contradiction:

Improveapplication rateVSAvoidspectrum of activity

Core Design Contradiction:

Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal composition that addresses multiple weed species through the combination of herbicide A, glufosinate, and optionally herbicide C. Each component contributes to controlling different weed groups, making the composition broadly effective across diverse weed spectra while allowing controlled application rates.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of operation

If post-emergent weed control is implemented to identify weed species, then specific weed control is achieved, but the control effectiveness against emerged weeds is reduced

Engineering Contradiction:

Improveweed identification capabilityVSAvoidcontrol effectiveness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent combines multiple herbicidal mechanisms in one composition that works effectively on emerged weeds. The synergistic interaction between herbicide A, glufosinate, and optionally herbicide C provides both post-emergent applicability (allowing weed identification) and enhanced control effectiveness, overcoming the typical reduction in efficacy associated with post-emergent treatment.

Inventive Principle:

Principle #5Merging (Combining)
