Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a cardiac device is implanted in the torso, then cardiac rhythm management is provided, but biometric information from body extremities is not available
Solution Approach 1:
The system is divided into two separate components: an implanted cardiac device in the torso and a wearable biometric sensor worn on the extremity. This segmentation allows each component to perform its specialized function while working together through wireless communication, resolving the contradiction by obtaining extremity biometric information without requiring a complex single integrated device.
Solution Approach 2:
A wireless communication intermediary transmits biometric data from the wearable sensor to the implanted cardiac device. This intermediary enables information exchange between the two separate components, allowing the cardiac device to receive and utilize extremity biometric information without direct physical connection, thus maintaining system simplicity while gaining access to needed data.
2Measurement precision
If biometric information from extremities is obtained, then accurate adjustment of cardiac device operation is achieved, but device complexity increases
Solution Approach 1:
The wearable biometric sensor is designed as a universal device that can be worn on any extremity and measures multiple biometric parameters (oxygenation, motion). This multi-functional approach allows accurate biometric measurement without requiring separate specialized devices for each measurement type, reducing overall system complexity while maintaining high measurement precision.
Solution Approach 2:
The system implements a feedback loop where biometric measurements from the extremity are transmitted to the cardiac device, which then automatically adjusts its operation. This closed-loop feedback enables accurate adjustment of cardiac device operation based on real-time extremity biometric data without requiring complex manual intervention or multiple separate control systems.
3Reliability
If automatic adjustment based on extremity biometric data is implemented, then tissue oxygenation is improved, but system complexity increases
Solution Approach 1:
The cardiac device automatically adjusts its operation based on received biometric data without requiring external intervention. The system performs self-service by processing the biometric information and making operational adjustments autonomously, which improves tissue oxygenation reliability while avoiding the need for complex external control systems or manual programming.
