Powdered Plant Activator for Wash-Off Resistance and Stability

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing plant activators face issues with insufficient persistence of their effects due to wash-off from plant surfaces, lacking long-lasting resistance-inducing and growth-promoting capabilities, and require improvements in handleability, transportability, and storage stability.

Innovation Solution

A powdery plant activator comprising oxo and hydroxy fatty acids or their derivatives, along with unsaturated fatty acids, is formulated to enhance persistence by minimizing wash-off and improve storage stability, handleability, and transportability, using a freeze-drying process to create a powdered form.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a liquid or soluble plant activator is applied to plants, then the activator can be easily absorbed and distributed, but the activator is washed away from the plant surface and does not remain at sufficient concentration

Engineering Contradiction:

Improveease of applicationVSAvoidpersistence of effect

Core Design Contradiction:

Ease of operationVSDuration of action of stationary object

Solution Approach 1:

The patent changes the physical state of the plant activator from liquid/soluble form to powder form. This parameter change allows the activator to adhere to plant surfaces without being washed away, while still maintaining its biological activity and ability to be absorbed when conditions are favorable.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite powder formulation that combines the plant activator with carrier materials. This composite structure provides both the ease of application associated with conventional formulations and the persistence needed to remain on plant surfaces, resolving the contradiction between ease of operation and duration of action.

Inventive Principle:

Principle #40Composite materials

2Duration of action of stationary object

If the plant activator concentration on plant surface is maintained, then the persistence of effect is improved, but the handleability and transportability become difficult

Engineering Contradiction:

Improvepersistence of effectVSAvoidhandleability

Core Design Contradiction:

Duration of action of stationary objectVSEase of operation

Solution Approach 1:

The patent transforms the activator into powder form, which fundamentally changes its handling characteristics. The powder can be easily stored, transported, and applied, yet when applied it adheres to plant surfaces providing persistent effects. This resolves the contradiction between persistence and handleability.

Inventive Principle:

Principle #35Parameter changes

3Duration of action of stationary object

If the plant activator is applied frequently to maintain effect, then the persistence is improved, but the labor and time consumption increase

Engineering Contradiction:

Improvepersistence of effectVSAvoidlabor saving

Core Design Contradiction:

Duration of action of stationary objectVSLoss of time

Solution Approach 1:

By changing the physical form to powder, the activator provides extended persistence on plant surfaces, reducing the frequency of applications needed. This directly addresses the contradiction by maintaining effect duration while reducing the time and labor loss associated with frequent reapplication.

Inventive Principle:

Principle #35Parameter changes

4Duration of action of stationary object

If the plant activator remains on plant surface, then the persistence of effect is improved, but the storage stability and transportability are compromised

Engineering Contradiction:

Improvepersistence of effectVSAvoidstorage stability

Core Design Contradiction:

Duration of action of stationary objectVSStability of the object's composition

Solution Approach 1:

The patent formulates the plant activator as a powder composite with appropriate carrier materials and protective agents. This composite structure maintains storage stability and facilitates transport, while the powder formulation itself provides the persistence needed on plant surfaces, resolving the contradiction between persistence and storage stability.

Inventive Principle:

Principle #40Composite materials
