Solution Overview

Problem

Increased resistance of weeds to existing herbicides like glyphosate and the need for broader weed control with enhanced durability and crop safety.

Innovation Solution

Combining 1,3,5 triazine herbicides with pelargonic acid or its derivatives, such as indaziflam or terbuthylazine, to create synergistic weed control with rapid and long-lasting effects, allowing for selective and residual weed control with minimal crop damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If glyphosate is used for weed control, then broad spectrum weed control is achieved, but increased resistance is observed and public concern intensifies

Engineering Contradiction:
Improveweed control spectrumVSAvoidherbicide effectiveness
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent combines pelargonic acid (a non-selective herbicide with quick burn-down effect) with triazine herbicides (selective herbicides with soil residual activity) to create a hybrid approach that maintains broad weed control spectrum while reducing resistance development. This merging of different herbicide modes of action allows effective control of emerged weeds without relying solely on glyphosate.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces naturally derived herbicides with different chemical properties and modes of action to change the parameter landscape of weed control options. By using pelargonic acid derivatives and triazine compounds with specific HRAC classification (C1 and L classes), the patent creates alternative parameter sets that bypass glyphosate resistance mechanisms while maintaining effectiveness.

Inventive Principle:
Principle #35Parameter changes

2Speed

If non-selective herbicides like pelargonic acid are used, then rapid weed control is achieved, but crop safety is reduced

Engineering Contradiction:
Improveweed control speedVSAvoidcrop damage
Core Design Contradiction:
SpeedVSObject-affected harmful factors

Solution Approach 1:

The patent applies different herbicide properties to different temporal stages of weed control: pelargonic acid provides rapid initial control (local quality of speed) while triazine herbicides provide selective residual control (local quality of crop safety). The combination allows rapid burn-down of emerged weeds followed by selective prevention of new weed emergence, thereby protecting crops.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses triazine herbicides with soil residual activity to perform preliminary protective action against future weed emergence. By applying these herbicides before weed problems become severe, they create a protective residue in the soil that prevents new weeds from establishing, thereby protecting crops from future damage while allowing rapid initial control with pelargonic acid.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If existing herbicide combinations are used, then weed control is achieved, but durability of control is reduced due to resistance

Engineering Contradiction:
Improveweed control efficiencyVSAvoidcontrol durability
Core Design Contradiction:
ProductivityVSDuration of action of stationary object

Solution Approach 1:

The patent creates a composite herbicide system combining pelargonic acid derivatives with triazine herbicides, where each component contributes different durability characteristics. The triazine component provides long-lasting soil residual activity that maintains control durability over time, while the pelargonic acid component provides immediate action. This composite approach extends the duration of effective control beyond what single herbicides can achieve.

Inventive Principle:
Principle #40Composite materials
