Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new technologies to assist in the recycling of resources, particularly in ensuring the authenticity and traceability of recycled resin products in the circular economy.
Innovation Solution
An authentication method and system using a computer system to track and authenticate resin products by acquiring and verifying information on inflow and outflow amounts, recycling ratios, and other conditions related to the use and processing of recycled resins, utilizing a blockchain network for consensus building and data storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional recycling tracking methods are used, then implementation simplicity is maintained, but authentication reliability and traceability of recycled resin products deteriorate
Solution Approach 1:
The patent combines multiple tracking functions (inflow amount tracking, outflow amount tracking, recycling ratio calculation, and authentication) into a single integrated blockchain system. This merging of previously separate tracking mechanisms into one unified system improves authentication reliability while managing complexity through consolidation rather than proliferation of separate systems
Solution Approach 2:
The blockchain network acts as an intermediary layer between manufacturing entities and recycling verification systems. This intermediary provides a decentralized, trustless environment for tracking and verifying recycled resin products, improving authentication reliability without requiring direct trust relationships between participating entities
2Measurement precision
If comprehensive tracking of inflow and outflow amounts is implemented, then authentication accuracy improves, but information processing complexity increases
Solution Approach 1:
The system enables manufacturing entities to automatically record and report their own inflow and outflow amounts directly to the blockchain. This self-service approach ensures accurate tracking data is captured at the source without requiring complex external verification systems, improving measurement precision while reducing overall system complexity
Solution Approach 2:
The blockchain system provides real-time feedback on authentication status and tracking data to participating entities. This feedback mechanism allows entities to verify their data accuracy and make corrections if needed, improving tracking precision while maintaining simple data entry processes
3Reliability
If blockchain consensus building is implemented, then data integrity is improved, but processing time increases
Solution Approach 1:
The authentication process is segmented into distinct phases: data collection at manufacturing entities, blockchain consensus building, and final authentication verification. This segmentation allows computationally intensive consensus operations to occur in the background while keeping the actual authentication process relatively fast for end users

AI summary
A new technology to assist the recycling of resources is provided. Provided is an authentication method for a recycled product performed by a computer system, the authentication method including: a first acquisition step of acquiring information on a receiving amount of a recycled resin in a manufacturing entity of a resin product; a second acquisition step of acquiring information on a sending amount of a resin product using the recycled resin in the manufacturing entity or a different manufacturing entity; and an authentication step of giving authentication to the resin product when an authentication condition based on the information on the sending amount and the receiving amount is satisfied.
