Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional self-monitoring blood glucose methods are used, then device complexity is reduced, but measurement frequency and timeliness deteriorate due to infrequent measurements
Solution Approach 1:
The system divides the monitoring function into two separate devices: a simple analyte sensor that performs continuous measurements and a remote communication device that handles data transmission and display. This segmentation allows the sensor to operate continuously without the complexity of integrated communication components, thereby increasing measurement frequency while keeping individual device complexity low.
Solution Approach 2:
The patent introduces a remote communication device as an intermediary between the analyte sensor and the user. This mediator handles the complex tasks of data transmission, storage, and display, allowing the sensor itself to remain simple while enabling continuous monitoring through periodic wireless communications.
2Measurement precision
If continuous monitoring is implemented, then measurement precision is improved, but use of energy deteriorates due to frequent transmissions
Solution Approach 1:
The system implements periodic data transmission instead of continuous transmission. The transceiver in the sensor device wakes up at predetermined intervals to transmit accumulated sensor data to the remote communication device, then returns to sleep mode. This periodic action maintains accurate continuous monitoring while significantly reducing average power consumption compared to continuous transmission.
Solution Approach 2:
The sensor device accumulates multiple sensor readings in its memory during sleep periods, then transmits them all at once during periodic wake periods. This self-service approach allows the device to maintain continuous monitoring capability while minimizing the frequency and duration of high-power transmission events, thereby reducing overall energy consumption.
3Loss of time
If transceiver is kept active for frequent transmissions, then data transmission timeliness is improved, but loss of energy increases
Solution Approach 1:
The sensor device continuously accumulates sensor data in its memory during sleep periods, preparing the data in advance for transmission. When the transceiver wakes up at predetermined intervals, it immediately transmits the pre-accumulated data without delay. This preliminary action of continuous data collection during sleep periods ensures timely data availability while maintaining low energy consumption during the majority of the time.
