Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication mechanisms are implemented to ensure device reliability, then measurement reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements authentication of sensing devices before they are used for patient monitoring. The control unit verifies device authenticity and checks expiry dates in advance of actual measurement operations, ensuring only valid devices are activated. This preliminary validation prevents unreliable measurements without requiring continuous complex verification during operation.
Solution Approach 2:
The control unit serves as an intermediary between the sensing device and the monitoring system. It mediates the authentication process by receiving sensing devices, verifying their authenticity and expiry status, and only then allowing data transmission. This intermediary role centralizes the complexity of authentication logic in a dedicated component rather than distributing it across the entire system.
2Measurement precision
If device expiry tracking is implemented to maintain measurement quality, then measurement precision is improved, but system complexity increases
Solution Approach 1:
The system tracks expiry dates of sensing devices and performs validation before use. The control unit checks whether the device has expired prior to activating it for patient monitoring, preventing degradation of measurement precision over time. This proactive expiry management ensures measurement quality without requiring continuous monitoring during operation.
Solution Approach 2:
The patent treats sensing devices as disposable components with defined service lifetimes. Rather than attempting to maintain and recalibrate expensive sensors indefinitely, the system uses relatively simple, replaceable sensing devices that are authenticated and validated for use within specific timeframes. Expired devices are discarded and replaced, ensuring measurement precision without complex maintenance protocols.
3Reliability
If comprehensive device authentication is performed to prevent unsuitable device use, then patient safety is improved, but operation time increases
Solution Approach 1:
Authentication and expiry verification are performed as preliminary steps before patient monitoring begins. The control unit validates the sensing device's authenticity and checks its expiry status in advance, ensuring patient safety protocols are met before clinical use. Once authenticated, the device remains validated for subsequent use, avoiding repeated time-consuming checks.
4Reliability
If secure communication protocols are implemented for sensor data transmission, then data reliability is improved, but communication overhead increases
Solution Approach 1:
The control unit establishes secure communication channels and validates device authenticity before data transmission begins. Authentication credentials are verified in advance, and secure protocols are initialized prior to patient monitoring. This preliminary setup ensures data reliability without requiring continuous heavy cryptographic operations during data acquisition, reducing ongoing communication overhead.
