Solution Overview

Problem

Current water repellent plant growth media and soils impede water infiltration and retention, leading to issues like dry patches and erosion, and existing wetting agents may be phytotoxic or lack adjuvant properties for enhancing agrochemical bioavailability.

Innovation Solution

A composition comprising a non-ionic alkylene oxide copolymer and a terpenic alkoxylate is used to enhance wetting and water retention in plant growth media, reducing hydrophobicity and improving the bioavailability of agrochemicals, which can be applied alone or with other materials like herbicides and fertilizers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If non-ionic wetting agents are used to improve water infiltration and retention, then water management performance is improved, but adjuvant properties for enhancing agrochemical bioavailability are not provided

Engineering Contradiction:
Improvewater management performanceVSAvoidadjuvant properties for agrochemical bioavailability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent combines a non-ionic wetting agent (polymer surfactant) with a penetrating agent (short chain alcohol or carboxylic acid) in a single composition. This merging allows the wetting agent to provide water management benefits while the penetrating agent provides adjuvant properties for enhancing agrochemical bioavailability, thus resolving the contradiction between water management performance and adjuvant functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The composition is designed to perform multiple functions simultaneously: the non-ionic wetting agent improves water infiltration and retention, while the penetrating agent enhances the bioavailability of agrochemicals. This multi-functionality allows a single product to address both water management and agrochemical efficacy, eliminating the need for separate products.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If polymer based wetting agents are used to improve wetting performance, then water retention is improved, but molecular size prevents adjuvant properties as penetration promoters

Engineering Contradiction:
Improvewetting performanceVSAvoidpenetration promotion capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The wetting agent composition is segmented into two distinct functional components: a non-ionic wetting agent (polymer surfactant) that provides water retention and wetting performance, and a separate penetrating agent (short chain alcohol or carboxylic acid) that provides penetration promotion capability. This segmentation allows each component to perform its specific function without interference from the other's molecular size limitations.

Inventive Principle:
Principle #1Segmentation
