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 deteriorates
Solution Approach 1:
The system performs wireless transmissions at periodic intervals rather than continuously. The analyte sensor system wakes from sleep mode at predetermined intervals to transmit data, then returns to low-power mode. This periodic operation maintains data reliability over time while significantly extending battery life by minimizing active transmission periods.
Solution Approach 2:
The system pre-configures transmission parameters and establishes communication protocols before actual data transmission begins. Calibration data and communication settings are prepared in advance during manufacturing or initial setup, allowing the device to enter sleep mode confidently knowing transmission parameters are ready, thus eliminating the need for frequent wake-ups for configuration.
2Duration of action of moving object
If wireless transmission is performed intermittently to conserve battery life, then battery life is improved, but reliability of data transmission deteriorates
Solution Approach 1:
The system incorporates acknowledgment mechanisms where the receiver confirms successful data reception. If a transmission fails or is not acknowledged, the system retransmits the data. This feedback loop ensures data reliability is maintained even with intermittent transmissions, as the periodic nature allows for retry attempts without requiring continuous operation.
Solution Approach 2:
The transmission interval is made dynamic rather than fixed. The system adjusts the frequency of wake-ups and transmissions based on factors such as data urgency, battery status, and communication success history. This dynamic adaptation allows the system to maintain reliability when needed while maximizing battery life during stable conditions.
3Ease of operation
If calibration data is stored and retrieved using identification tags, then ease of operation is improved, but device complexity increases
Solution Approach 1:
Instead of storing complex calibration data directly in the sensor system, the patent uses identification tags (barcodes or RFID tags) that contain only unique identifiers. The actual calibration data is copied from a centralized database using these identifiers. This approach simplifies the sensor device while maintaining ease of operation, as users only need to scan the simple identification tag rather than manually input complex calibration parameters.
Solution Approach 2:
The identification tag serves as an intermediary between the user and the calibration system. Rather than directly interfacing with complex calibration databases or procedures, the user simply scans the tag, and the system uses this intermediate identifier to automatically retrieve the appropriate calibration data. This intermediary simplifies the user interface while managing the underlying complexity through automated lookups.
