Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital calibration certificates are stored in centralized DCC servers or hubs, then the certificates can be stored and made available for evaluation, but users must access the correct server by maintaining lists of DCC locations and checking revocation lists distributed among servers, increasing system complexity
Solution Approach 1:
The patent divides the centralized DCC server system into multiple distributed blockchain nodes, each storing copies of calibration certificates. This segmentation eliminates the need for a central authority while distributing the storage and validation functions across multiple independent nodes, thereby maintaining reliability without requiring complex centralized management structures
Solution Approach 2:
Each blockchain node in the patent performs multiple functions: storing calibration certificates, validating their authenticity through cryptographic verification, and providing access to users. This multi-functionality replaces the need for separate systems for storage, management, and distribution that characterized the centralized approach, reducing overall system complexity while maintaining reliability
2Ease of operation
If digital calibration certificates are stored in centralized servers, then the certificates can be managed centrally, but revocation lists must be distributed among servers and users must check them, increasing operational complexity
Solution Approach 1:
The blockchain system implements immediate feedback through its immutable ledger structure. When a calibration certificate is revoked, the revocation is recorded on the blockchain and instantly visible to all nodes and users. This eliminates the need for users to periodically check distributed revocation lists, as the system automatically provides real-time feedback on the validity status of any certificate through cryptographic verification
Solution Approach 2:
The blockchain acts as an intermediary layer between certificate issuance and validation. Instead of users directly checking distributed revocation lists across multiple servers, the blockchain mediates the validation process by providing a single source of truth that all nodes trust. This intermediary function simplifies the operation for users while maintaining centralized management of revocation status through the decentralized ledger
