Solution Overview

Problem

Existing technologies have not effectively promoted root nodule and root hair formation in leguminous plants, with a lack of focus on root hair formation and insufficient methods for early-stage application of compositions.

Innovation Solution

A composition comprising peptide-based and sugar-based biosurfactants with an agriculturally acceptable carrier, optionally including a soybean meal degradation product, is applied to plant seeds or soil to promote root nodule and root hair formation, utilizing biosurfactants' specific effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional compositions (e.g., stearyl alcohol with surfactant) are applied to promote root nodule formation, then root nodule number increases, but the application methods are limited and insufficient for early-stage promotion

Engineering Contradiction:

Improveroot nodule formation promotionVSAvoidapplication stage flexibility

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent changes the chemical composition parameters by using peptide-based and sugar-based biosurfactants instead of conventional surfactants and stearyl alcohol. This parameter change enables the composition to be effective at earlier application stages (seed coating, seedling stage) while maintaining or enhancing root nodule formation promotion, thus resolving the contradiction between productivity improvement and application stage flexibility

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent applies the composition at preliminary stages including seed coating before planting and seedling stage treatment. This preliminary action allows the biosurfactant-containing composition to establish beneficial effects early in plant development, expanding application versatility to earlier stages while maintaining effective root nodule formation promotion

Inventive Principle:

Principle #10Preliminary action

2Productivity

If conventional compositions are used for root growth promotion, then root growth is enhanced, but root hair formation promotion has not been examined or described

Engineering Contradiction:

Improveroot growth promotionVSAvoidroot hair formation mechanism knowledge

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The patent extracts and focuses specifically on root hair formation as a separate and distinct function from general root growth promotion. By using peptide-based and sugar-based biosurfactants, the invention isolates and addresses the previously unexamined root hair formation mechanism, providing targeted information about this specific physiological process while maintaining overall root growth enhancement

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces peptide-based and sugar-based biosurfactants as intermediary substances that mediate between the applied composition and root hair formation. These biosurfactants act as specific mediators that trigger and enhance root hair development, filling the knowledge gap about how external applications can specifically promote root hair formation rather than just general root growth

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If peptide-based and sugar-based biosurfactants are used in the composition, then root nodule and root hair formation are significantly enhanced, but the composition complexity increases

Engineering Contradiction:

Improveroot nodule and root hair formationVSAvoidcomposition formulation complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent employs peptide-based and sugar-based biosurfactants that serve multiple functions simultaneously: they promote root nodule formation, enhance root hair formation, and improve overall root growth. This multi-functionality allows a single composition type to address multiple plant physiological processes, reducing the need for separate treatments and effectively managing composition complexity while achieving enhanced productivity across multiple parameters

Inventive Principle:

Principle #6Universality (Multi-functionality)
