Solution Overview

Problem

The widespread adoption of reducing nitrogen fertilizer use in agriculture is hindered by the need to maintain crop yields while minimizing greenhouse gas emissions, as nitrogen is essential for plant growth and current methods lack efficient verification and validation for carbon credit incentives.

Innovation Solution

A computer-implemented system using a distributed ledger, such as a blockchain, to track and verify the use of nitrogen fertilizer and nitrogen-fixing microbial products, ensuring accurate recording and validation of reduced fertilizer application and associated carbon credit eligibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If nitrogen fertilizer use is reduced to minimize greenhouse gas emissions, then environmental impact is improved, but crop yield may deteriorate because nitrogen is essential for plant growth

Engineering Contradiction:

Improvegreenhouse gas emissionsVSAvoidcrop yield

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The system implements continuous monitoring of nitrogen fertilizer application through sensors and satellite imagery, with data fed back to farmers via a mobile application. This feedback loop enables farmers to adjust their fertilizer application strategies in real-time, optimizing the balance between maintaining crop yields and reducing nitrogen over-application that leads to greenhouse gas emissions

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces traditional mechanical verification methods with satellite-based remote sensing and automated monitoring systems. Satellite imagery and sensors detect nitrogen fertilizer application patterns, replacing manual field inspections and paper-based record-keeping, thereby enabling scalable verification of reduced fertilizer use for carbon credit programs

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If traditional verification methods are used for carbon credit validation, then system complexity is reduced, but measurement precision and reliability of fertilizer reduction verification deteriorate

Engineering Contradiction:

Improveverification system complexityVSAvoidfertilizer reduction verification accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The system employs satellite imagery that serves multiple functions: monitoring crop health, detecting nitrogen fertilizer application, verifying reduced fertilizer use, and providing baseline data for carbon credit calculation. This multi-functional approach consolidates what would otherwise require separate verification systems into a single integrated platform

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces satellite-based remote sensing as an intermediary between farmers and carbon credit verification authorities. The satellites objectively detect and record nitrogen fertilizer application data, serving as a neutral third-party mediator that provides trustworthy verification without requiring direct involvement or trust in manual reporting systems

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If manual verification methods are used for carbon credit eligibility, then ease of operation is improved, but productivity and efficiency of carbon credit program implementation deteriorate

Engineering Contradiction:

Improveverification process simplicityVSAvoidcarbon credit validation efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The system enables automated self-verification where satellite data automatically detects nitrogen fertilizer application patterns and generates verification reports for carbon credit eligibility. Farmers receive notifications and can review their own verification status through the mobile application, eliminating the need for manual field inspections and paper-based verification processes

Inventive Principle:

Principle #25Self-service

AI summary

A computer-implemented system and method to collect and store data related to product stored in a container. In response to filling the container with the product, the following data are stored in at least one first record in an external database (such as a distributed ledger, e.g., blockchain): a product type of the first product; an amount of the first product filled into the first container; a unique identity of the first container; and a unique identity of a first user of the first container at the time of filling the first container with the first product. Data representing a unique identity of a container data module on the container are stored in the container data module. As the container moves, dispenses product, and undergoes changes in possession and ownership, data representing such events are stored in the distributed ledger and/or the container data module. As a result, a verifiable application/consumption record of the product within the container is generated.
