Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If in vivo analyte monitoring systems are implemented, then glucose monitoring frequency and reliability are improved, but device complexity and cost increase
Solution Approach 1:
The monitoring system is divided into separate functional modules: sensor control device implanted in vivo for data collection, reader device for data reception and processing, and mobile device with dedicated applications for user interface and data management. This segmentation allows each component to be optimized independently, improving overall reliability while managing complexity through modular design.
Solution Approach 2:
A reader device acts as an intermediary between the implanted sensor control device and the mobile device. It receives data from the sensor, processes it, and transmits it to the mobile device, thereby decoupling the complex sensing operations from the user interface and simplifying the overall system architecture.
2Adaptability or versatility
If multiple applications are allowed to interface with sensor data, then user convenience and application versatility improve, but data security and system reliability deteriorate
Solution Approach 1:
The system performs preliminary authentication of third-party applications before granting access to sensor data. The sensor interface application verifies the legitimacy of requesting applications and establishes secure communication channels in advance, ensuring data security is maintained while allowing multiple approved applications to interface with the system.
Solution Approach 2:
The system implements a feedback mechanism where the sensor interface application monitors and controls access to sensor data based on application authentication status. Approved applications receive necessary data while unapproved applications are denied access, thereby maintaining security while enabling versatile application support.
3Productivity
If real-time analyte data is continuously displayed, then glycemic control effectiveness improves, but energy consumption and device complexity increase
Solution Approach 1:
Instead of continuous real-time display, the system updates analyte data at periodic intervals determined by the sensor broadcast schedule and application logic. This periodic updating maintains effective glycemic control by providing timely data while significantly reducing energy consumption compared to continuous display refreshes.
