Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless transmission of glucose data is implemented continuously, then monitoring reliability is improved, but battery life deteriorates
Solution Approach 1:
The patent implements periodic transmission of glucose data at predetermined intervals instead of continuous transmission. The transmitter sends analyte data to the display device at scheduled times, which maintains monitoring reliability while significantly reducing power consumption and extending battery life of the implantable sensor system.
Solution Approach 2:
The system dynamically adjusts transmission parameters based on battery status and monitoring needs. The display device can initiate requests for analyte data and the transmitter can adjust transmission timing based on remaining battery life, creating a flexible system that balances reliability and power consumption.
2Loss of energy
If intermittent transmission is used to conserve battery life, then battery efficiency is improved, but data transmission reliability deteriorates
Solution Approach 1:
The system incorporates feedback mechanisms where the display device monitors battery status and sends requests for analyte data based on received information. The transmitter uses this feedback to adjust transmission timing and ensure data is sent at appropriate intervals, maintaining reliability while optimizing battery efficiency through informed decision-making about when to transmit.
Solution Approach 2:
The display device can send preliminary requests for analyte data before critical thresholds are reached. By proactively requesting data at planned intervals rather than waiting for battery depletion or critical glucose levels, the system ensures reliable data transmission while maintaining efficient battery usage patterns.
3Ease of operation
If finger pricking methods are used for glucose monitoring, then measurement simplicity is improved, but user comfort deteriorates
Solution Approach 1:
The patent replaces the mechanical finger pricking method with an implantable electrochemical sensor that continuously measures glucose levels in interstitial fluid. This substitution eliminates the need for repeated needle punctures and manual blood sampling, dramatically improving user comfort while maintaining measurement capability through wireless data transmission to a display device.
