Solution Overview

Problem

The high power consumption required for maintaining and updating distributed ledgers when storing value information, particularly for green electricity generation, is a challenge due to the need for complex calculations and storage capacity, which becomes wasteful when the value decreases over time.

Innovation Solution

An information processing method that calculates second value information based on attribute information linked to first value information stored in a distributed ledger, allowing for reduced power consumption by factoring in the date and time of generation and other attributes to determine appropriate value.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If value information indicating green electricity generation is stored in a distributed ledger, then information integrity and traceability are improved, but power consumption for maintaining and updating the ledger increases

Engineering Contradiction:

Improveinformation integrityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent extracts only the essential attribute information (date and time of generation) from the complete value information and stores it in the distributed ledger. This selective extraction reduces the storage burden and computational requirements for maintaining the ledger, thereby lowering power consumption while preserving the core functionality of tracking green electricity generation credibility.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies different quality levels to different types of information: complete value information is retained locally where it is generated, while only essential attribute information is distributed to the ledger. This local quality approach ensures that each system component stores only what is necessary for its function, reducing overall power consumption while maintaining information integrity.

Inventive Principle:

Principle #3Local quality

2Measurement precision

If attribute information is factored into value calculations, then measurement precision of value information is improved, but device complexity increases

Engineering Contradiction:

Improvevalue information accuracyVSAvoidcalculation process complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent performs preliminary action by pre-storing attribute information (date and time of generation) in the distributed ledger before value calculations are needed. This allows calculation devices to simply retrieve and use the pre-processed attribute information without performing complex real-time analysis, thereby improving measurement precision while minimizing device complexity.

AI summary

An information processing method includes: storing, into a distributed ledger, transaction data indicating first value information that indicates a first value and to which attribute information of the first value is linked; reading the first value information indicated in the transaction data stored in the distributed ledger, and performing a calculation process of calculating second value information indicating a second value, by performing, for the first value information that has been read, an operation in which the attribute information linked to the first value information is factored; and outputting the second value information calculated in the calculation process.
