Solution Overview

Problem

Conventional fertilizers, both inorganic and organic, face challenges such as high leaching potential, burning of plant roots, and low nitrogen content, which necessitate frequent reapplication and limit their effectiveness in providing readily available nitrogen to plants.

Innovation Solution

A method involving the production of a liquid organic fertilizer from animal manure, where suspended solids are removed and an acid is added to create a liquid waste filtrate, followed by an evaporation process, resulting in a fertilizer with high Ammoniacal Nitrogen content (4-10%) that is 100% water soluble and quickly available to plants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If inorganic fertilizers are used to provide high nitrogen content, then nitrogen availability is improved, but plant root burning and leaching increase

Engineering Contradiction:

Improvenitrogen contentVSAvoidplant root burning

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical form of nitrogen from inorganic (ammonium nitrate, urea) to organic (ammoniacal nitrogen in liquid fertilizer), maintaining high nitrogen content while altering the delivery mechanism to reduce burning. The liquid formulation with controlled ammonia concentration provides nitrogen without the harsh effects of solid inorganic fertilizers.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses liquid fertilizer as an intermediary medium between inorganic nitrogen sources and plant roots. This liquid carrier delivers nitrogen slowly and uniformly, preventing direct contact between concentrated inorganic nitrogen and root surfaces, thus eliminating burning while maintaining nitrogen availability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If inorganic fertilizers are used to provide high nitrogen content, then nitrogen availability is improved, but leaching potential increases

Engineering Contradiction:

Improvenitrogen contentVSAvoidnutrient leaching

Core Design Contradiction:

Quantity of substanceVSLoss of substance

Solution Approach 1:

The patent implements continuous nitrogen release through slow decomposition of organic matter in the liquid fertilizer. This continuous action prevents sudden nutrient pulses that cause leaching, while maintaining steady nitrogen availability for plant growth over an extended period.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The patent changes the release rate parameter of nitrogen from rapid (inorganic) to slow (organic decomposition), transforming the temporal distribution of nitrogen availability. This slower release kinetics reduces leaching while maintaining sufficient nitrogen content for plant needs.

Inventive Principle:

Principle #35Parameter changes

3Object-affected harmful factors

If organic fertilizers are used to reduce burning and leaching, then soil health is improved, but nitrogen content and release speed decrease

Engineering Contradiction:

Improveplant root burningVSAvoidnitrogen content

Core Design Contradiction:

Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

The patent changes the concentration parameter of nitrogen in the liquid fertilizer formulation to achieve 4-10% ammoniacal nitrogen, which is higher than conventional organic fertilizers. This parameter adjustment maintains the benefits of organic delivery while providing sufficient nitrogen content to meet crop needs.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent copies the slow-release mechanism of conventional organic fertilizers while using liquid ammonia as the nitrogen source. This allows the system to maintain organic fertilizer benefits (no burning, low leaching) while achieving higher nitrogen content through the concentrated liquid ammonia component.

Inventive Principle:

Principle #26Copying

4Object-affected harmful factors

If organic fertilizers are used to reduce burning and leaching, then soil health is improved, but application frequency increases

Engineering Contradiction:

Improveplant root burningVSAvoidreapplication frequency

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent implements continuous nitrogen release through slow decomposition of organic matter in the liquid fertilizer. This continuous action provides sustained nitrogen availability over time, reducing the frequency of reapplication needed compared to inorganic fertilizers that require frequent dosing to maintain effectiveness.

Inventive Principle:

Principle #20Continuity of useful action
