Solution Overview

Problem

Existing herbicides often fail to achieve effective control of harmful plants while maintaining compatibility with useful plants, particularly dicotyledonous crops, and require application within a narrow time frame influenced by weather conditions.

Innovation Solution

Formulations comprising a compound of formula (I) in combination with herbicides and safeners, which enhance herbicidal activity and broaden the spectrum of effectiveness, allowing for improved compatibility with useful plants and flexible application timing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If highly effective herbicides are used to control harmful plants, then herbicidal activity is improved, but compatibility with useful plants deteriorates

Engineering Contradiction:

Improveherbicidal activityVSAvoiddamage to useful plants

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces safeners as intermediary substances that mediate between the herbicide and useful plants. These safeners selectively protect useful plants from herbicide damage through mechanisms such as inducing protective enzymes, competing for metabolic pathways, or forming protective complexes, while not interfering with the herbicide's action on harmful plants.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent modifies the chemical parameters of the herbicide composition by combining compounds of formula (I) with other herbicides and safeners in specific ratios. This changes the overall toxicity profile and selectivity of the formulation, enabling effective control of harmful plants while reducing damage to useful plants through synergistic or antagonistic interactions.

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If application rates are reduced to spare useful plants, then compatibility with useful plants is improved, but control of harmful plants deteriorates

Engineering Contradiction:

Improvedamage to useful plantsVSAvoidcontrol of harmful plants

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent merges multiple herbicidally active compounds with different modes of action and toxicity profiles into a single formulation. This combination allows the compounds to work synergistically, achieving enhanced control of harmful plants at lower application rates while the presence of safeners further protects useful plants from damage.

Inventive Principle:

Principle #5Merging (Combining)

3Device complexity

If a single herbicidally active compound is used, then formulation simplicity is improved, but spectrum of activity deteriorates

Engineering Contradiction:

Improveformulation complexityVSAvoidspectrum of activity

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent creates a multi-functional herbicide formulation where compounds of formula (I) work in combination with other herbicides to target multiple weed species and physiological pathways. This universal formulation can control a broad spectrum of harmful plants including grasses, broadleaf weeds, and woody plants, while maintaining relative formulation simplicity through standardized combination ratios.

Inventive Principle:

Principle #6Universality (Multi-functionality)
