Solution Overview

Problem

There is a need for sustainable agricultural compositions that can effectively control pests, particularly phytoparasitic nematodes, while minimizing environmental impact and promoting eco-friendly practices.

Innovation Solution

A method involving the digestion of organic plant material by fly larvae, followed by crushing the larvae with the digested material to create a phytosanitary composition rich in nutrients and molecules, including glucosamine, which is then used as a biological pesticide.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If chemical phytosanitary products are used to control pests, then pest control effectiveness is improved, but environmental toxicity and persistence increase

Engineering Contradiction:

Improvepest control effectivenessVSAvoidenvironmental toxicity

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention converts the harmful waste material (fly larvae) into a beneficial phytosanitary product with nematicide activity. The larvae, which would normally be discarded as waste or require separate processing, are instead integrated into the composition to provide active pest control components, thereby converting a potential harm (waste management burden) into a benefit (effective nematicide source).

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The invention changes the physical and chemical parameters of the organic material by incorporating fly larvae and their digestive byproducts. This transformation modifies the composition's biological activity, converting inert organic matter into an active phytosanitary product with proven nematicide efficacy against plant-parasitic nematodes.

Inventive Principle:

Principle #35Parameter changes

2Quantity of substance

If fly larvae are separated from organic material after digestion, then fertilizer quality is improved, but phytosanitary activity is reduced

Engineering Contradiction:

Improvenutritional contentVSAvoidnematicide activity

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The invention merges two previously separate functions into a single integrated composition: fertilization and pest control. By combining the digested organic material (fertilizer component) with the fly larvae and their byproducts (phytosanitary component), the composition simultaneously provides both nutritional benefits to plants and protective benefits against nematodes, eliminating the need for separate application of fertilizer and pesticide.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The final composition achieves multi-functionality by serving dual purposes: as a fertilizer providing nutritional content and as a phytosanitary product providing nematicide activity. This universal product replaces the need for separate fertilizer and pesticide applications, offering both functions in a single sustainable solution.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If sustainable organic compositions are used, then environmental friendliness is improved, but pest control effectiveness may be reduced

Engineering Contradiction:

Improveenvironmental impactVSAvoidphytosanitary activity

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The invention utilizes fly larvae, which have a short life cycle and can be rapidly produced from waste organic material. These larvae serve as a temporary, renewable source of active phytosanitary components that can be continuously generated from waste, providing a sustainable and cost-effective alternative to persistent chemical pesticides while maintaining effective nematicide activity.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
