Solution Overview

Problem

Current biological plant protection products face challenges with the lower efficacy of microorganisms due to inadequate survival capacity during storage and application, leading to reduced reach of active ingredients at the target locus and rapid degradation by environmental factors.

Innovation Solution

The use of a polyether compound as a carrier for active ingredients, which improves storage stability, maintains low viscosity at low temperatures for better handling, and is self-emulsifiable or water-soluble, allowing for enhanced dilutability and distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If microorganisms are used as active ingredients in biological plant protection products, then environmental friendliness and reduction of chemical pesticide residues are improved, but survival capacity during storage and application deteriorates

Engineering Contradiction:

Improvechemical pesticide residuesVSAvoidsurvival capacity of microorganisms

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent introduces a carrier substance as an intermediary between the microorganisms and the external environment. This carrier protects microorganisms from harmful environmental factors during storage and application, thereby improving their survival capacity while maintaining the environmental benefits of biological plant protection products.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent modifies the physical and chemical parameters of the carrier substance to optimize microorganism protection. By adjusting properties such as viscosity, emulsifiability, and water solubility, the carrier creates optimal conditions for microorganism survival without compromising the environmental friendliness of the product.

Inventive Principle:

Principle #35Parameter changes

2Stability of the object's composition

If polyether compound is used as carrier, then storage stability and dilutability are improved, but viscosity at room temperature increases

Engineering Contradiction:

Improvestorage stabilityVSAvoidhandling viscosity

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent carefully selects and adjusts the molecular weight, chain length, and structural parameters of the polyether compound to achieve an optimal balance. These parameter changes allow the carrier to maintain low viscosity at room temperature for easy handling, while providing sufficient storage stability and protection for microorganisms.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If polyether compound with high water solubility is used, then dilutability and distribution are improved, but emulsification capability deteriorates

Engineering Contradiction:

ImprovedilutabilityVSAvoidemulsification capability

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent optimizes the hydrophilic-lipophilic balance (HLB) of the polyether compound by adjusting the ratio of hydrophilic ether groups to hydrophobic alkyl chains. This parameter optimization enables the carrier to exhibit both good water solubility for easy dilution and sufficient emulsification capability for homogeneous distribution of microorganisms.

Inventive Principle:

Principle #35Parameter changes

AI summary

Compositions containing at least one compound of Formula (I) are useful as carriers for at least one active ingredient.In Formula (I), R1 is a monovalent aliphatic radical having 1 to 22 carbon atoms; R2 is in each case independently a hydrogen radical or a methyl radical; n is a number from 1 to 300; and at least one R2 radical is a methyl radical. Methods can be used for storing the active ingredient in the carrier and active ingredient compositions contain both the carrier and the active ingredient. The active ingredient compositions can be used for the treatment of plants, seed, and soils; and can be used as a biostimulant, a probiotic food supplement, a probiotic animal feed additive, a plant protection product, or a probiotic medicament. The active ingredient compositions can be used in corresponding methods of treating plants, seed, or soils.
