Solution Overview

Problem

Agricultural productivity is hindered by shrinking land availability, soil depletion, and changing environmental conditions, while the use of harmful chemicals like herbicides, insecticides, and fungicides is prevalent, necessitating innovative solutions for sustainable food production.

Innovation Solution

The development of microbial consortia comprising diverse microbial species such as Bacillus, Azospirillum, Pseudomonas, and others, which are applied to soil and plants to enhance biodegradation and agricultural processes, reducing the need for chemical inputs by promoting soil health and plant growth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If chemical fertilizers and pesticides are used to increase crop yields, then productivity is improved, but harmful factors are introduced to the environment and soil health deteriorates

Engineering Contradiction:

Improvecrop yieldVSAvoidchemical pollution

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent converts harmful chitin-containing materials (insect exoskeletons, fungal cell walls) into beneficial resources by using microbial consortia to degrade them into plant growth promoters and biofertilizers. This transforms waste products into valuable agricultural inputs, eliminating the need for chemical pesticides while improving soil health and crop yields.

Inventive Principle:

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

Solution Approach 2:

The microbial consortia perform multiple functions autonomously: degrading chitin, producing plant growth hormones, fixing nitrogen, and solubilizing phosphorus. This self-service capability eliminates the need for external chemical inputs, allowing the system to sustain itself and improve productivity without harmful chemical fertilizers or pesticides.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If diverse microbial species are introduced to enhance biodegradation, then environmental sustainability is improved, but system complexity increases

Engineering Contradiction:

Improvebiodegradation capabilityVSAvoidconsortia composition

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple microbial species with complementary functions into integrated consortia. Each species performs a specific function (chitin degradation, nitrogen fixation, phosphorus solubilization, plant growth promotion), and their combined actions create a synergistic system that achieves comprehensive biodegradation and plant growth enhancement without requiring complex management.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The microbial consortia are designed to perform multiple functions simultaneously: degrading various chitin-containing materials, producing multiple plant growth promoters, fixing nitrogen, and solubilizing phosphorus. This multi-functionality reduces the need for separate chemical products and simplifies agricultural management while enhancing environmental sustainability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If chemical inputs are reduced to improve soil health, then environmental sustainability is improved, but productivity may decrease

Engineering Contradiction:

Improvesoil contaminationVSAvoidcrop yield

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent changes the fundamental parameters of soil fertility management by replacing chemical fertilizers with biological processes. Microbial consortia naturally fix nitrogen, solubilize phosphorus, and produce growth hormones, transforming the soil ecosystem to generate fertility internally. This eliminates chemical contamination while maintaining or improving crop yields through enhanced soil biological activity.

Inventive Principle:

Principle #35Parameter changes
