Solution Overview

Problem

Current power trading systems lack the capability to differentiate and execute trades based on various power generation methods, particularly failing to prioritize the use of renewable energy over exhaustible energy effectively.

Innovation Solution

A power trading system utilizing a blockchain-based distributed ledger that enables peer-to-peer trading between V2G apparatuses, allowing for the discrimination and management of electric energy from exhaustible and renewable sources, and preferentially consuming renewable energy to minimize CO2 emissions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a unified power trading system is used, then trading execution is simplified, but the ability to differentiate and prioritize by power generation method is lost

Engineering Contradiction:
Improvetrading execution simplicityVSAvoidpower generation method differentiation
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent segments the power trading system into multiple independent trading channels, each dedicated to a specific power generation method (renewable energy, exhaustible energy, etc.). This segmentation allows the system to maintain simplified trading execution within each channel while simultaneously supporting differentiation across multiple power generation types, thus resolving the contradiction between operational simplicity and adaptability.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If renewable energy prioritization is implemented, then environmental contribution increases, but trading system complexity increases

Engineering Contradiction:
ImproveCO2 emissions reductionVSAvoidtrading system complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by pre-establishing priority rules for renewable energy trading before actual trading occurs. The system automatically identifies and prioritizes renewable energy transactions based on predetermined criteria, eliminating the need for complex real-time decision-making algorithms. This approach reduces CO2 emissions while keeping the trading system relatively simple, as the prioritization logic is embedded in advance rather than calculated dynamically.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If detailed power generation method tracking is implemented, then carbon emissions calculation accuracy improves, but data management complexity increases

Engineering Contradiction:
ImproveCO2 emissions calculation accuracyVSAvoiddata management complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies segmentation by creating separate data tracking streams for each power generation method. Instead of managing all power data in a single complex system, the patent divides data management into distinct segments corresponding to different power generation types (solar, wind, fossil fuel, etc.). This segmentation enables accurate CO2 emissions calculation for each segment while simplifying overall data management, as each segment can be handled independently with standardized procedures.

Inventive Principle:
Principle #1Segmentation
