Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted between infusion pumps using current methods, then data exchange is simple and fast, but security is compromised allowing data manipulation and unauthorized access
Solution Approach 1:
The system performs preliminary pairing and key exchange between infusion pumps before actual data transmission. During the pairing process, pumps establish secure communication channels and exchange cryptographic keys in advance, so that when therapy data needs to be transmitted, the secure pathway is already established and ready for immediate use.
Solution Approach 2:
The patent introduces cryptographic intermediaries including digital signatures and encryption protocols as mediators between infusion pumps. These intermediaries verify data authenticity and protect transmission security without requiring direct unsecured connections between devices, thus maintaining reliability while managing complexity through standardized security layers.
2Reliability
If digital signatures and encryption are implemented between infusion pumps, then data security is improved, but processing time and computational resources increase
Solution Approach 1:
Cryptographic keys and security parameters are established during the pairing phase before therapy initiation. This preliminary setup allows the system to perform encryption and decryption operations during data transmission without requiring complex real-time key generation, thus maintaining data integrity while minimizing time loss during actual therapy data exchange.
Solution Approach 2:
The system dynamically adjusts cryptographic parameters based on the type and urgency of data being transmitted. For example, less critical status information may use lighter encryption schemes while critical therapy parameters use stronger encryption, optimizing the balance between data integrity and transmission time for different data categories.

AI summary
An infusion pump system has a first infusion pump and a second infusion pump that are paired or pairable to one another for secure data transmission. At least one of the first and second infusion pumps receives data signed with a digital signature, and/or at least one of the first and second infusion pumps receives data encrypted with an encryption. A method can be used for secure data transmission for the infusion pump system. The secure data transmission method can be performed using a computer-readable storage medium having functions that cause the infusion pump system to perform the method.
