Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless transmission of analyte data is performed continuously, then reliability of data transmission is improved, but battery life is reduced
Solution Approach 1:
The system implements periodic wake-up cycles where the sensor system alternates between low-power sleep mode and active transmission mode. During each cycle, the sensor wakes up at predetermined intervals to transmit analyte data, then returns to sleep mode. This periodic operation maintains data transmission reliability over time while significantly extending battery life compared to continuous transmission.
2Duration of action of moving object
If transmission interval is increased to conserve battery, then battery life is improved, but reliability of monitoring is reduced
Solution Approach 1:
The system incorporates feedback mechanisms where the sensor system monitors its own operational state and adjusts transmission timing accordingly. The sensor can detect events such as analyte level thresholds being crossed or rapid changes in analyte concentration, and trigger immediate transmissions outside the regular periodic cycle. This feedback-driven approach ensures critical data is transmitted reliably while maintaining extended battery life through reduced routine transmissions.
