Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If genomic data is shared across multiple platforms for precision medicine, then data interoperability and research value are improved, but privacy breach risks and security vulnerabilities increase
Solution Approach 1:
The patent segments genomic data into multiple blocks distributed across different blockchain networks. Each blockchain maintains a portion of the data, preventing any single point of failure or unauthorized access while enabling interoperability through standardized data structures and protocols.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer between data storage and access. Smart contracts act as mediators that enforce access policies, authentication mechanisms, and data sharing agreements, allowing secure interoperability without direct platform-to-platform connections.
2Speed
If genomic data is stored in a centralized system for easy access, then data retrieval speed is improved, but security vulnerabilities and single points of failure increase
Solution Approach 1:
The patent divides the centralized storage model into distributed blockchain networks where genomic data is segmented across multiple nodes. This distribution eliminates single points of failure while maintaining reliable access through the decentralized consensus mechanism and replicated data structures.
Solution Approach 2:
The patent transitions from a single-dimensional centralized storage model to a multi-dimensional distributed blockchain architecture. Data exists across multiple dimensions (different blockchain networks, nodes, and layers), providing redundant access paths that maintain retrieval speed while enhancing security through spatial distribution.
3Object-affected harmful factors
If genomic data is encrypted for security, then privacy protection is improved, but data accessibility and analysis capability deteriorate
Solution Approach 1:
The patent applies different encryption and access control mechanisms to different portions of genomic data based on sensitivity and usage requirements. Critical personal identifiers receive stronger encryption, while anonymized segments allow broader access for research, creating local variations in security measures that balance protection and accessibility.
Solution Approach 2:
The patent performs preliminary anonymization and encryption of genomic data before storage on the blockchain. Access control policies and decryption keys are pre-configured through smart contracts, enabling automated access management that protects privacy while maintaining accessibility for authorized users without requiring real-time security decisions.
4Reliability
If multiple blockchains are used for data distribution, then security and decentralization are improved, but system complexity and coordination overhead increase
Solution Approach 1:
The patent implements universal data structures and standardized interfaces that function across multiple blockchain networks. The same data format, consensus mechanism, and smart contract templates can operate on different blockchains, reducing coordination complexity while maintaining the security benefits of distributed architecture.
Solution Approach 2:
The patent merges multiple blockchain systems into a coordinated network where data is distributed across chains but managed through unified smart contract logic and cross-chain communication protocols. This combining approach maintains decentralization and security while presenting a simplified interface to users and reducing overall system complexity through integration.
