Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ambulatory medical devices and hospital medical devices operate independently without integration, then device complexity and data management overhead are reduced, but data sharing efficiency and coordinated patient care capability deteriorate
Solution Approach 1:
The patent employs an intermediary integration system that mediates between ambulatory medical devices and hospital medical devices. This intermediary layer handles data translation, protocol conversion, and secure communication establishment, allowing the two device types to exchange information without direct complex integration. The intermediary manages the communication sessions and data flows, reducing the complexity burden on individual devices while enabling efficient data sharing.
2Reliability
If comprehensive patient data is shared in real-time between devices, then patient care quality and emergency response capability are improved, but data security risks and communication overhead increase
Solution Approach 1:
The patent implements preliminary authentication and trust establishment procedures before data sharing begins. Devices perform mutual authentication and establish trusted relationships in advance through secure handshaking protocols. Data classification and permission settings are configured beforehand, ensuring that only authorized data elements are shared with appropriate recipients. This preliminary preparation reduces security risks while enabling reliable real-time data exchange when needed.
Solution Approach 2:
The system dynamically adjusts data sharing parameters based on patient condition and context. During emergency situations, the system changes parameters to allow broader data access and faster transmission. In stable conditions, more restrictive parameters apply to maintain security. The communication protocol adjusts data compression levels, transmission frequency, and detail granularity based on urgency, balancing security with care quality requirements.
3Object-affected harmful factors
If secure communication sessions are established between devices, then data transmission security is improved, but communication setup time and processing overhead increase
Solution Approach 1:
Authentication credentials and trust relationships are established in advance before actual data transmission occurs. Devices perform initial mutual authentication and store verified credentials for future use. When communication is needed, the system retrieves pre-established trust relationships rather than performing full authentication sequences, significantly reducing setup time while maintaining security. Session keys and encryption parameters are prepared beforehand for rapid secure communication initiation.
Solution Approach 2:
The communication session security parameters are dynamically adjusted based on the urgency and type of data being transmitted. For time-critical emergency data, the system uses pre-established secure channels with minimized handshaking. For routine data exchanges, more thorough authentication sequences are performed. The security protocol adapts its rigor based on contextual needs, balancing security requirements with time constraints in different clinical scenarios.
