Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted between infusion pumps without encryption or digital signatures, then the data transmission process is simple and fast, but the security and integrity of the data cannot be ensured
Solution Approach 1:
The patent introduces cryptographic intermediaries (digital signatures and encryption algorithms) as mediators between the transmitting and receiving pumps. These intermediaries authenticate data origin and protect data integrity without requiring direct trust between pumps, thus enhancing security while maintaining system modularity
Solution Approach 2:
The patent implements preliminary cryptographic setup where pumps exchange public keys and establish encryption parameters before actual data transmission. This preliminary action ensures that when data is transmitted, the security framework is already in place, allowing secure communication without adding complexity to the ongoing transmission process
2Reliability
If data is encrypted and digitally signed between infusion pumps, then data security and integrity are ensured, but the data transmission process becomes more complex
Solution Approach 1:
The patent implements self-service mechanisms where each pump automatically generates its own key pairs, digitally signs its own data, and verifies incoming signatures using the other pump's public key. This automation eliminates manual cryptographic operations, making the system secure without increasing operational complexity for users
Solution Approach 2:
The patent changes the operational parameters of data transmission by incorporating cryptographic parameters (signatures, encrypted fields) into the data structure. These parameter changes are transparent to users as the system automatically handles the cryptographic transformations, maintaining ease of operation while ensuring data integrity
3Reliability
If infusion pumps exchange information without authentication, then the takeover mode can be initiated quickly, but the system is vulnerable to unauthorized manipulation
Solution Approach 1:
The patent implements preliminary key exchange and authentication setup before the takeover mode is initiated. Pumps establish cryptographic credentials in advance, so when takeover is needed, the authentication process is already complete or can be rapidly executed, minimizing delay while ensuring therapy safety
Solution Approach 2:
The patent replaces manual verification and authentication mechanisms with automated cryptographic verification. The digital signature system automatically validates data authenticity and integrity, substituting time-consuming manual checks with rapid computational verification, thus reducing synchronization time while maintaining therapy safety
