Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain technology is used for data storage, then data reliability and security are improved, but block size limitations reduce storage capacity and frequency
Solution Approach 1:
The patent extracts only the essential data from digital twin systems and stores it on the blockchain, while maintaining full access to the original data through references. This selective extraction approach ensures data reliability and security on the blockchain without being constrained by block size limitations, as only critical data metadata is stored rather than all data.
Solution Approach 2:
The patent introduces an intermediary layer between the digital twin data sources and the blockchain. This intermediary manages data filtering, selection, and representation, allowing high-frequency data to be processed and only essential information to be stored on-chain. The intermediary enables reliable blockchain storage without direct block size constraints limiting the system.
2Ease of operation
If real-time data is stored on blockchain, then data accessibility is improved, but block size and frequency limitations reduce real-time capability
Solution Approach 1:
The system extracts and stores only essential data metadata on the blockchain at high frequency, while maintaining full access to complete data through references stored in decentralized storage. This enables real-time data accessibility and high-frequency updates without being limited by blockchain block size constraints.
Solution Approach 2:
The patent transitions from storing all data directly on the blockchain to a two-dimensional architecture where blockchain stores metadata and decentralized storage holds the actual data. This dimensional shift enables high-frequency real-time access without block size limitations, as the blockchain layer operates at a different level of data abstraction.
3Reliability
If data is made immutable on blockchain, then data security is improved, but flexibility for corrections is reduced
Solution Approach 1:
The system extracts only essential data for immutable blockchain storage, while allowing flexibility in the original data sources. Corrections or updates to non-critical data can be made in the decentralized storage layer without affecting the immutable blockchain record, maintaining security while preserving adaptability where needed.
Solution Approach 2:
The patent applies local quality by making different parts of the data system have different immutability characteristics. Critical data metadata is made immutable on the blockchain for security, while other data components maintain flexibility for corrections and updates in the decentralized storage layer, allowing each component to have the appropriate level of rigidity.
Data Source
AI summary
A computer implemented method and system is described which uses blockchain technology as a storage system for data acquired from a digital twin. The blockchain can be used to generate an immutable transaction history of data produced by the digital twin. In the case of an error, failure, incident, or accident, parties of interest can then access and analyse an immutable set of data. The blockchain network can also execute a digital smart contract based on the data received from a digital twin. The invention may be used in conjunction with the Bitcoin blockchain or another blockchain protocol.
