Solution Overview

Problem

Current crop nutritional compositions, such as fertilizers, are poorly distributed in soils due to non-uniform wetting characteristics, leading to uneven moisture and nutrient availability, which results in poor crop vigor and lower yields.

Innovation Solution

A soil wetting agent comprising siloxane alkoxylate, an anionic polymeric dispersant, a pH adjuster, a sugar, and a carrier resin, which enhances water and bioactive material distribution across the soil profile.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If fertilizer is applied by broadcasting, then fertilizer can be distributed across the soil surface, but poor absorption occurs due to non-uniform wetting characteristics and hydrophobic areas

Engineering Contradiction:
Improvefertilizer distributionVSAvoidabsorption efficiency
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent applies a soil wetting agent containing siloxane alkoxylate before or with fertilizer application to pre-treat the soil surface. This preliminary action modifies the soil's wetting characteristics, reducing hydrophobicity and creating uniform absorption pathways, thereby ensuring reliable fertilizer absorption when broadcasting is used.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The siloxane alkoxylate acts as an intermediary substance between the hydrophobic soil and the aqueous fertilizer solution. It modifies the soil surface properties to improve wettability, enabling better contact and absorption of fertilizer without changing the application method itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If irrigation water is applied to hydrophobic soil, then water enters the soil in localized areas, but this causes puddling or channeling and leaves surrounding areas untreated

Engineering Contradiction:
Improvewater distributionVSAvoiduniformity of distribution
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The patent changes the physical-chemical parameters of the soil surface by applying siloxane alkoxylate, which modifies wetting characteristics. This parameter change transforms hydrophobic soil into hydrophilic soil, enabling uniform water distribution across the entire soil surface rather than localized puddling or channeling.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The soil wetting agent is applied in advance to counteract the hydrophobic effect that would otherwise cause non-uniform water distribution. By pre-modifying the soil surface, the patent prevents the harmful channeling and puddling effects before irrigation occurs.

Inventive Principle:
Principle #9Preliminary anti-action

3Reliability

If conventional soil wetting agents are used, then water distribution improves, but the complexity of the composition increases with multiple components

Engineering Contradiction:
Improvewater distributionVSAvoidcomposition complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses a composite wetting agent composition containing siloxane alkoxylate combined with other components. This composite approach leverages the synergistic effects of different materials to achieve reliable water distribution while managing composition complexity through careful selection and optimization of components.

Inventive Principle:
Principle #40Composite materials
