Solution Overview

Problem

Current methods for calculating carbon stock in forests rely heavily on actual measurement data, which can be insufficient, making it difficult to estimate carbon stock accurately.

Innovation Solution

An apparatus and method for calculating the change of carbon stock in a terminal, which includes a database and a control unit that collects forest information, uses allometric equations or growth coefficients to calculate carbon stock, and determines the total carbon stock for an evaluation area, even in the absence of actual measurement data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If actual measurement data is used to calculate carbon stock, then measurement precision is improved, but device complexity and loss of time increase due to insufficient data availability

Engineering Contradiction:
Improvecarbon stock calculation accuracyVSAvoidinsufficient actual measurement data
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent introduces intermediary models (allometric equations and growth coefficients) that mediate between available forest inventory data and the target carbon stock calculation. These models serve as intermediaries to bridge the gap when direct measurement data is insufficient, allowing accurate estimation without requiring complete actual measurement data for all forest parameters.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transforms the calculation approach by changing from direct measurement-based parameters to model-based parameters. By using allometric equations that relate measurable parameters (like diameter at breast height and tree height) to unmeasured parameters (carbon stock), the system can accurately calculate carbon stock by changing the parameter transformation method rather than relying solely on direct measurements.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If allometric equations are used to calculate carbon stock, then ease of operation is improved, but measurement precision may worsen due to estimation rather than direct measurement

Engineering Contradiction:
Improvecarbon stock calculation convenienceVSAvoidcarbon stock estimation accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent makes the calculation system universal by incorporating multiple approaches (actual measurement method and allometric equation method) that can be applied across different forest types and conditions. The system automatically selects the appropriate method based on data availability, making it universally applicable while maintaining both ease of operation and measurement precision through adaptive methodology.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system incorporates feedback mechanisms by comparing results from different calculation methods and adjusting the approach based on data quality and availability. When actual measurement data is available, the system uses direct measurement; when not available, it switches to allometric equations, creating a feedback-driven selection process that maintains accuracy while ensuring ease of operation.

Inventive Principle:
Principle #23Feedback

3Productivity

If forest management plans are implemented continuously, then productivity is improved, but carbon storage function deteriorates due to repeated thinning and afforestation

Engineering Contradiction:
Improveforest management efficiencyVSAvoidcarbon storage function stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by calculating carbon stock changes before and after forestry projects are implemented. By performing baseline carbon stock assessments before management interventions and comparing them with post-intervention measurements, the system can predict and evaluate the impact of continuous management practices on carbon storage, allowing for proactive adjustment to maintain carbon sequestration functionality.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system replaces direct mechanical forest management monitoring with a computational model-based assessment system. Instead of physically measuring every forest parameter during each management cycle, the system uses allometric equations and growth coefficients to substitute and calculate carbon stock changes, reducing the mechanical burden of continuous field measurements while maintaining assessment reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An apparatus for calculating a change of carbon stock in a terminal includes: a database; and a control unit that confirms an administrative district and a map sheet of an evaluation area to calculate a change of carbon stock of vegetation before and after forestry project, collects forest information in an evaluation area from the database, collects one of an allometric equation and a growth coefficient using the collected forest information, calculates the carbon stock of the vegetation by applying a diameter at a breast height and a tree height to the collected allometric equation when the allometric equation is collected, determines that the calculated carbon stock of the vegetation is a carbon stock for a total area of the evaluation area, and calculates the change of the carbon stock of the vegetation by considering the carbon stock for the determined total area.
