Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication is used between infusion pump and CGM device, then convenience and remote monitoring capability are improved, but communication reliability deteriorates due to interference from the human body
Solution Approach 1:
The system performs preliminary actions by tracking device locations and evaluating communication signal quality before critical data transmission occurs. It establishes a map of reliable communication zones in advance, allowing the system to proactively alert users to potential communication issues before they result in data loss, thereby maintaining both convenience and reliability.
Solution Approach 2:
The system continuously monitors communication signal quality between the infusion pump and CGM device, providing real-time feedback about communication reliability. Based on this feedback, the system can alert users to relocate devices or take corrective actions, creating a closed-loop system that maintains communication reliability while preserving wireless convenience.
2Reliability
If device placement is optimized for signal quality, then communication reliability is improved, but user convenience and comfort deteriorate due to placement constraints
Solution Approach 1:
The system dynamically evaluates communication signal quality at different device locations and provides real-time guidance to optimize placement. Rather than requiring fixed optimal positions, the system adapts to user movements and provides ongoing feedback, allowing users to maintain communication reliability while preserving flexibility in device placement and wear comfort.
3Reliability
If communication signal quality is continuously monitored, then communication issues are detected earlier, but system complexity and power consumption increase
Solution Approach 1:
The system leverages existing multi-functional components in smartphones and wearables (GPS, accelerometers, communication modules) to perform location tracking and signal quality monitoring without adding dedicated specialized hardware. This approach enables continuous monitoring capability while minimizing increases in system complexity and power consumption by reusing existing universal components.
