Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional centralized healthcare systems are used to manage EMRs, then administrative overhead and operational costs are high, but data security and patient control are compromised
Solution Approach 1:
The patent segments the centralized healthcare system into a decentralized network of independent nodes (healthcare providers, patients, third-party applications) that each maintain their own copies of the EMR data. This segmentation eliminates the single point of failure and reduces administrative overhead by distributing management responsibilities across the network rather than requiring a central authority.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer that enables secure peer-to-peer data sharing without requiring a central administrator. The blockchain ledger acts as a trusted mediator that records all access and modifications to EMRs, providing security and auditability while eliminating the need for centralized administrative overhead.
2Speed
If EMRs are stored in centralized databases, then access and retrieval are fast, but data integrity and immunity to tampering are compromised
Solution Approach 1:
The patent creates multiple identical copies of EMR data distributed across numerous network nodes. Each node stores a complete or partial copy of the medical records, ensuring that data integrity is maintained through redundancy. The blockchain technology ensures that all copies remain synchronized and tamper-proof, while patients can access their data from any node in the network.
Solution Approach 2:
The patent implements a standardized data structure and format for EMRs across all network nodes, ensuring homogeneity in how medical records are stored and accessed. This standardization enables consistent data integrity validation across the decentralized network while maintaining efficient access speeds through uniform data organization.
3Adaptability or versatility
If patient data is shared across multiple healthcare providers, then interoperability and care coordination improve, but privacy and compliance with regulations become difficult to maintain
Solution Approach 1:
The patent implements local quality control by allowing different levels of data access and sharing permissions for different patients and healthcare providers. Each patient can specify which portions of their medical records should be shared with which providers, and the system enforces these granular permissions locally at each node while maintaining overall interoperability across the network.
Solution Approach 2:
The patent incorporates automated feedback mechanisms through smart contracts that continuously monitor data access and sharing activities. The system provides real-time feedback to patients about who accesses their data and for what purposes, and automatically enforces compliance with privacy regulations by blocking unauthorized access attempts. This feedback loop maintains privacy and compliance while enabling broad interoperability.
4Reliability
If blockchain technology is implemented for EMR management, then data security and patient control are enhanced, but system complexity and implementation costs increase
Solution Approach 1:
The patent designs the blockchain-based EMR system to perform multiple functions simultaneously: it provides secure data storage, enables patient-controlled access permissions, maintains audit trails, ensures compliance with regulations, and facilitates interoperability between providers. By consolidating these functions into a single decentralized platform, the system reduces overall complexity compared to maintaining separate systems for each function.
Solution Approach 2:
The patent implements self-service capabilities where patients can directly manage their own data permissions, access their records, and control who sees their information without requiring intermediary administrators. The smart contracts automatically enforce access rules and manage data sharing, eliminating the need for complex manual approval processes and reducing operational complexity despite the underlying blockchain infrastructure.
