Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transmission of glucose data is implemented, then convenience and continuous monitoring capability are improved, but battery life is reduced
Solution Approach 1:
The system implements intermittent transmission where the sensor transmits glucose data at predetermined time intervals rather than continuously. The controller receives data at these periodic intervals and updates the display accordingly, reducing overall power consumption while maintaining monitoring capability.
Solution Approach 2:
The system dynamically adjusts transmission and display update frequencies based on operational conditions. The controller can modify update rates to balance between providing timely glucose information and conserving battery power, allowing flexible operation modes.
2Use of energy by moving object
If intermittent transmission is used to conserve battery life, then energy consumption is reduced, but reliability of data transmission is compromised
Solution Approach 1:
The controller implements feedback mechanisms to monitor data reception and system operation. When glucose data is received at predetermined intervals, the controller updates the display and can adjust future transmission parameters based on operational needs, ensuring reliable monitoring while managing power consumption.
Solution Approach 2:
The system is configured with predetermined transmission intervals and buffer capacities that allow it to maintain reliable operation in advance. Data is collected and buffered during intervals, ensuring that even with intermittent transmission, the system maintains adequate data availability for monitoring and alert functions.
3Loss of time
If continuous monitoring is implemented, then timeliness of hyperglycemic/hypoglycemic detection is improved, but patient comfort and compliance are reduced due to frequent finger pricking
Solution Approach 1:
The system replaces the mechanical finger-pricking method with a wireless sensor that continuously or intermittently monitors glucose levels through less invasive means. The sensor transmits data wirelessly to a controller, eliminating the need for repeated manual blood sampling while maintaining continuous monitoring capability.
Solution Approach 2:
The wireless sensor system creates a continuous digital copy of glucose level data, replacing the discrete physical blood samples. This allows the controller to track glucose trends over time without requiring actual repeated blood draws, improving both timeliness and patient comfort.
