Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional SMBG methods are used, then device complexity is reduced, but measurement precision and frequency are insufficient leading to delayed detection
Solution Approach 1:
The patent replaces the mechanical finger-pricking method with a transdermal sensor system that uses electrochemical or optical detection mechanisms to measure glucose levels continuously through the skin, eliminating the need for painful mechanical punctures while enabling more frequent and accurate measurements
Solution Approach 2:
The patent introduces a transdermal sensor as an intermediary device that bridges the gap between the body's glucose levels and the monitoring system, allowing non-invasive measurement through the skin barrier and enabling continuous data collection without direct blood sampling
2Productivity
If continuous glucose monitoring is implemented, then measurement frequency is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic action by enabling the sensor to transmit data at configurable intervals rather than continuously, allowing the system to balance monitoring frequency with power consumption. The sensor can remain active for continuous measurement while entering low-power states between transmission windows
Solution Approach 2:
The patent applies dynamics by allowing flexible adjustment of transmission parameters including interval, duration, and scheduling based on user needs and battery status. The system can dynamically adapt its monitoring and communication behavior to optimize the trade-off between data freshness and energy usage
3Loss of information
If frequent data transmissions are performed, then information availability is improved, but energy consumption increases
Solution Approach 1:
The patent uses periodic action by establishing transmission windows that occur at scheduled intervals rather than continuous transmission. This allows the sensor to maintain data freshness while minimizing transmission time and energy consumption during low-power states
Solution Approach 2:
The patent applies preliminary action by pre-configuring transmission schedules and parameters before use. The system can establish expected transmission times and durations in advance, allowing the user to balance information availability needs against energy conservation preferences without real-time adjustments
4Reliability
If transmission windows are extended, then data transmission reliability is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by allowing flexible adjustment of transmission window duration and scheduling based on signal strength, interference conditions, and power availability. The system can extend transmission time when needed for reliable data transfer while keeping the transceiver in low-power mode during the majority of the monitoring period
