Solution Overview

Problem

Agricultural applications require large volumes of water for active ingredient application, limiting tractor capacity and efficiency, and existing formulations necessitate multiple trips for refilling, which is labor-intensive and inefficient.

Innovation Solution

Development of an emulsifiable foaming concentrate with an organic phase containing an agriculturally active ingredient and a foaming agent, capable of forming a foam with a low water content, allowing for precise and efficient application at significantly reduced volumes, such as 0.25-1.00 gallons per acre.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If conventional spray formulations are used, then active ingredient can be applied to crops, but large volumes of water (9 gallons/acre) are required, exceeding tractor capacity and requiring multiple refilling trips

Engineering Contradiction:
Improvevolume of liquid formulationVSAvoidplanting efficiency
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The patent changes the physical state and composition parameters of the formulation by incorporating foaming agents that transform the liquid concentrate into a foam structure. This parameter change allows the same active ingredient dose to be delivered in a reduced volume (0.25-1.00 gallons per acre versus conventional 9 gallons per acre), resolving the contradiction between quantity of substance and productivity

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent utilizes phase transition by converting the liquid formulation into a foam phase through the action of foaming agents. This phase transition creates a气液 mixture that occupies less liquid volume while maintaining the necessary active ingredient concentration, enabling single-trip application and improving planting efficiency

Inventive Principle:
Principle #36Phase transitions

2Quantity of substance

If multiple trips are made to refill tractor tanks, then adequate water volume is available for treatment, but valuable planting time is lost and labor intensity increases

Engineering Contradiction:
Improvevolume of water carriedVSAvoidplanting time
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

By changing the formulation parameters to create a foam-based system, the patent reduces the total liquid volume required for application by a factor of 9 to 36 compared to conventional sprays. This allows the tractor to carry sufficient treatment volume for the entire field in a single load, eliminating refilling trips and associated time losses

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If large volumes of water are used for application, then active ingredient is effectively distributed, but resource efficiency decreases and application precision is reduced

Engineering Contradiction:
Improvevolume of waterVSAvoidapplication precision
Core Design Contradiction:
Quantity of substanceVSMeasurement precision

Solution Approach 1:

The patent changes the formulation from a dilute liquid spray to a concentrated foam structure, where the active ingredient is delivered in a much smaller volume (0.25-1.00 gallons per acre). This parameter change improves application precision by reducing the carrier volume and minimizing drift, while also improving resource efficiency by reducing water consumption by a factor of 9 to 36

Principle #35Parameter changes
