Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If decentralized blockchain storage is implemented for MR implant information data, then data reliability and security are improved, but system complexity increases
Solution Approach 1:
The system segments data storage into two distinct layers: critical verification data (hashes, timestamps, digital signatures) is stored on the blockchain for immutability, while bulk clinical data is stored in traditional databases. This segmentation allows the system to leverage blockchain's reliability for authentication without requiring the entire system to adopt blockchain's complexity.
Solution Approach 2:
The patent introduces an intermediary verification layer that mediates between the blockchain and traditional database systems. This intermediary component handles the complexity of blockchain interactions (hash verification, digital signature validation) while presenting a simplified interface to end users, thus improving reliability through blockchain without fully exposing system complexity.
2Ease of operation
If comprehensive implant data is stored in centralized databases, then data accessibility is improved, but data security and trustworthiness deteriorate
Solution Approach 1:
The system performs preliminary actions by generating cryptographic hashes and digital signatures during data ingestion, before data is stored. These cryptographic artifacts are embedded in the blockchain, establishing trustworthiness in advance. This allows the system to maintain high data accessibility in traditional databases while ensuring trustworthiness through pre-established cryptographic verification mechanisms.
Solution Approach 2:
The patent creates cryptographic copies (hashes and digital signatures) of the original implant data and stores these copies on the blockchain. These copies serve as immutable verification records that don't interfere with the accessibility of the original data in traditional databases, thus maintaining ease of operation while improving data trustworthiness through verifiable copies.
3Device complexity
If manual data verification processes are used for implant information, then system complexity is reduced, but time consumption and error rates increase
Solution Approach 1:
The patent replaces manual mechanical verification processes with automated cryptographic verification. Digital signatures and hash functions automatically verify data authenticity and integrity, eliminating the need for manual checking while reducing verification time. This substitution maintains process simplicity for end users while dramatically improving efficiency through automated cryptographic validation.
Solution Approach 2:
The system implements self-service verification where the blockchain structure automatically provides authentication and validation services. Data integrity is self-verified through cryptographic hashes and digital signatures embedded in the blockchain, eliminating the need for external manual verification processes. This self-service mechanism reduces both time consumption and maintains simplicity by making verification automatic and transparent.
