Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Blockchain technology is used for electronic record management, then data immutability and security are improved, but transaction processing speed deteriorates
Solution Approach 1:
The patent segments the electronic record system into modular components: hash function modules that process data independently, read-only memory modules that store immutable records, and database modules that manage queryable data. This segmentation allows parallel processing of multiple records simultaneously, improving transaction speed while maintaining immutability through cryptographic hashing of each segment.
2Reliability
If Blockchain technology is used for electronic record management, then data security is improved, but energy consumption increases
Solution Approach 1:
The patent extracts the essential security function from the complex Blockchain consensus mechanism, retaining only the cryptographic hash function that provides immutability. By removing the energy-intensive mining and consensus verification processes while keeping the hash-based integrity verification, the system achieves comparable security with dramatically reduced energy consumption.
3Reliability
If Blockchain technology is used for electronic record management, then data integrity is improved, but storage requirements increase
Solution Approach 1:
The patent creates a streamlined copy of the Blockchain integrity mechanism by storing only essential immutable records in read-only memory and maintaining a separate queryable database copy for efficient access. This copying strategy reduces storage requirements by eliminating redundant full-node copies while preserving data integrity through hash verification of the read-only memory records.
4Productivity
If hash function and read-only memory are used for electronic record management, then transaction processing speed is improved, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary layer between the immutable read-only memory and the queryable database, using hash functions as the mediating mechanism. This intermediary allows fast verification of data integrity without requiring complex Blockchain consensus protocols, simplifying the system architecture while maintaining high transaction processing speeds through straightforward hash comparison operations.
Data Source
AI summary
A computerized method produces a continuous, auditable, chronological electronic record. The method uses, by a computer system, a hash function to convert a first set of data stored in a database into a first hash value. The first set of data is a first module. The computer system stores the first module and the first hash value into a read-only memory. The computer system inserts the first hash value into a second set of data recorded in the database after the first set of data was recorded. The computer system also uses the hash function to convert the second set of data stored in the database into a second hash value. The second set of data is a second module. The computer system stores the second module and the second hash value into the read-only memory.
