Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If digital calibration certificates are stored in a centralized institution, then data management is simplified, but the system cannot be completely tamper-proof and loses non-repudiation
Solution Approach 1:
The patent segments the centralized certificate storage into a distributed network of nodes using blockchain technology. Each node maintains a copy of the certificate data, eliminating the single point of failure and enabling tamper-proof storage through cryptographic hashing and distributed consensus mechanisms.
Solution Approach 2:
The patent introduces a trusted third-party intermediary (such as a certification authority or time-stamping service) that verifies and seals the digital certificates before they are stored on the blockchain. This intermediary adds a layer of trust and non-repudiation without requiring the storage institution to maintain absolute security.
2Reliability
If digital calibration certificates are isolated and independent, then individual certificate security is maintained, but reliable calibration chains cannot be formed
Solution Approach 1:
The patent merges isolated digital certificates into a continuous chain by linking each certificate to its parent and child certificates through cryptographic hash references. This creates an unbroken calibration chain that maintains individual certificate security while enabling efficient verification of the entire traceability chain.
Solution Approach 2:
The patent ensures continuity of the calibration chain by implementing a mechanism where each certificate continuously references its predecessor and successor, creating an unbroken chain of trust. This allows for efficient verification of the entire calibration hierarchy without manual intervention.
3Adaptability or versatility
If manual processing is used to establish calibration chains, then flexibility is maintained, but the process is time-consuming and error-prone
Solution Approach 1:
The patent implements self-service automation where the system automatically establishes calibration chains by cryptographically linking certificates based on their hierarchical relationships. The blockchain network autonomously verifies and records the chain connections, eliminating manual processing while maintaining the flexibility to accommodate different calibration scenarios through programmable smart contracts.

AI summary
The present invention discloses a trusted alliance block chain digital calibration certificate system and an operation method therefor. The system comprises: a distributed ledger system (10) of a distributed storage system based on a hyperledger fabric; a CA system (11) for management of all entity identity certificates and registration of identities in the system; a UTC time calibration server (12) for providing a UTC time calibration service for all block chain node servers of the system; and a digital calibration certificate subsystem (13) for generating, by means of alliance management, instrument organization management, and calibration institution management, a digital calibration certificate from calibration certificate data by a digital signature technology, extracting related entity information, and forming original information of multiple data blocks. The system can overcome the shortcomings of existing block chain technology-based digital calibration certificate technologies by establishing a calibration chain and a traceability chain which are reliable, trusted, secure, and continuously growing.
