NFT Traceability for Articles with Changing Storage States
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing NFT management systems face challenges in traceability when the manner of storage for an article, such as wine, is changed during its production or distribution process, making it difficult to track the article's state before the storage change.
Innovation Solution
A method of managing non-fungible tokens (NFTs) that involves monitoring a first article with a first sensor and obtaining second articles through changes in storage, with each monitored by a second sensor, and recording sensor data from both sensors on a distributed ledger network to associate the NFTs, ensuring traceability across different storage states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a consistent monitoring system is used for articles, then the system structure remains simple, but traceability is lost when the manner of storage changes
Solution Approach 1:
The patent segments the monitoring system into multiple types (first monitoring system for bulk storage, second monitoring system for individual storage) that can be applied根据不同 storage manners. This allows the system to adapt to different storage configurations without requiring complete system redesign, thereby maintaining traceability while controlling complexity
Solution Approach 2:
The patent implements a dynamic system where the monitoring approach changes based on the storage manner. When storage manner changes from bulk to individual (or vice versa), the system dynamically switches between different monitoring configurations and creates corresponding NFTs, ensuring continuous traceability throughout the article's lifecycle
2Adaptability or versatility
If the manner of storage is changed during production or distribution, then the article can be processed flexibly, but traceability to the original state becomes difficult
Solution Approach 1:
The patent creates NFTs in advance for each storage state before the actual storage manner change occurs. When an article transitions from bulk storage to individual storage, the system has already prepared the corresponding NFT structure, enabling immediate and accurate tracking of the new state while maintaining linkage to the previous state
Solution Approach 2:
The patent introduces NFTs as an intermediary that bridges different storage states. Each NFT acts as a digital certificate that links the article's previous state (bulk storage) to its new state (individual storage), ensuring that traceability is maintained throughout the transformation process without losing information about the original state

AI summary
A plurality of second articles are obtained from a first article by changing a manner of storage of the first article. A method of managing an NFT includes: managing a first NFT associated with the first article, the first NFT being issued using distributed ledger technology; and managing a plurality of second NFTs respectively associated with the plurality of second articles, the plurality of second NFTs being issued to each correspond to the first NFT using the distributed ledger technology. The managing of the first NFT includes recording first sensor data obtained by the first sensor, in association with the first NFT. The managing of the plurality of second NFTs includes recording second sensor data obtained by the second sensor, in association with the plurality of second NFTs.
