Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain technology is used for secure data transactions, then data integrity and security are improved, but system complexity increases
Solution Approach 1:
The patent introduces a cryptographic checksum as an intermediary mechanism that simplifies the blockchain system's complexity. Instead of requiring full blockchain implementation, the checksum acts as a lightweight mediator that provides data integrity verification through cryptographic hashing, thereby maintaining reliability while reducing system complexity.
Solution Approach 2:
The patent extracts the essential security function from the complex blockchain system by isolating the cryptographic checksum calculation and verification process. This extraction allows the core data integrity mechanism to be implemented independently without requiring the full blockchain infrastructure, thus reducing system complexity while preserving reliability.
2Reliability
If cryptographic checksums are calculated for all data structures, then data security is improved, but processing time increases
Solution Approach 1:
The patent applies partial action by calculating cryptographic checksums selectively rather than for all data structures. The system determines when checksum calculation is necessary based on data sensitivity and transaction requirements, thereby providing adequate security for critical data while avoiding unnecessary processing time for less sensitive information.
Solution Approach 2:
The patent changes the parameter of cryptographic verification by using hash functions that balance security strength with computation speed. By selecting appropriate hash algorithms and adjusting security parameters based on data importance, the system achieves acceptable data security while minimizing processing time overhead.
3Ease of manufacture
If distributed database systems are implemented, then intermediary costs are reduced, but infrastructure complexity increases
Solution Approach 1:
The patent extracts the essential trust-verification function from the distributed database system by implementing standalone cryptographic checksum verification. This allows organizations to achieve intermediary-free transaction verification without deploying full distributed database infrastructure, thereby reducing transaction costs while avoiding the complexity of maintaining distributed ledger systems.
Solution Approach 2:
The patent enables self-service security verification through local cryptographic checksum calculation and validation. Each system can independently verify data integrity using cryptographic methods without requiring participation in a distributed database network, thus eliminating intermediary costs while avoiding the infrastructure complexity of distributed ledgers.
