Solution Overview

Problem

Conventional sticking agents for agrochemicals fail to effectively prevent agrochemicals from running off or detaching from plant surfaces due to rainfall or wind, leading to reduced agricultural productivity, increased costs, and environmental safety concerns.

Innovation Solution

A sticking agent composition comprising a fatty acid triglyceride, a fatty acid, and a polyoxyalkylene sorbitol fatty acid ester, which improves the sticking property and rainproof stability of agrochemicals by forming a strong coating on plant surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If conventional sticking agents (edible oil and fat or generic vegetable oils) are used, then formulation stability is improved, but sticking property and rainproof stability are insufficient

Engineering Contradiction:

Improveformulation stabilityVSAvoidsticking property and rainproof stability

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

The patent uses a composite material system consisting of three specific components: fatty acid triglyceride (Component A), fatty acid (Component B), and polyoxyalkylene sorbitol fatty acid ester (Component C). This composite formulation works synergistically to provide both formulation stability and superior sticking property with rainproof stability, overcoming the limitations of single-component conventional sticking agents.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent specifies precise parameter ranges for each component to optimize performance: Component A requires acyl groups with 8-18 carbon atoms, Component B requires alkyl or alkenyl groups with 11-19 carbon atoms, and Component C requires specific polyoxyalkylene structures. By controlling these chemical parameters within defined ranges, the formulation achieves both stability and reliable sticking properties.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If agrochemicals are sprayed on plants, then pest control effect is achieved, but agrochemicals easily run off or detach due to rainfall or wind

Engineering Contradiction:

Improvepest control effectVSAvoidpest control persistence

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The sticking agent composition is applied together with the agrochemical formulation before the agrochemical can be washed away by rainfall or wind. The sticking agent pre-forms a coating on the plant surface that anchors the agrochemical, preventing run-off and detachment before they can occur, thus maintaining pest control persistence.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The sticking agent forms a flexible thin film coating on the plant surface that adheres the agrochemical particles. This film structure allows the agrochemical to remain attached to the plant surface even under environmental stressors like rainfall and wind, extending the duration of pest control effect.

Inventive Principle:

Principle #30Flexible shells and thin films

3Productivity

If repeated agrochemical applications are conducted, then agricultural productivity is maintained, but production cost and environmental burden increase

Engineering Contradiction:

Improveagricultural productivityVSAvoidagrochemical application quantity

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The sticking agent enables continuous retention of the agrochemical on the plant surface, ensuring that the pest control effect persists over time without requiring additional applications. This continuous action maintains agricultural productivity while reducing the total quantity of agrochemical needed.

Inventive Principle:

Principle #20Continuity of useful action
