Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the wireless device continuously monitors millimeter wave cell availability to provide accurate indication, then the accuracy of indicating millimeter wave cellular availability is improved, but the power consumption increases
Solution Approach 1:
The system performs preliminary actions by establishing criteria for millimeter wave cell availability indication before actual indication is needed. Motion status information and location information are collected and evaluated in advance to determine when indication should be displayed, avoiding continuous monitoring while maintaining accuracy.
Solution Approach 2:
The wireless device uses its own motion sensing circuitry and location information capabilities to self-determine millimeter wave cell availability. By leveraging internally available data (accelerometer, gyroscope, location services) rather than continuous external signal monitoring, the device serves itself in determining availability, reducing power consumption while maintaining indication accuracy.
2Device complexity
If the wireless device releases the link with millimeter wave cell to reduce complexity, then the device complexity is reduced, but the accuracy of indicating availability deteriorates
Solution Approach 1:
Motion status information and location information serve as intermediary indicators that correlate with millimeter wave cell availability without requiring continuous direct link monitoring. These intermediaries provide indirect but accurate information about availability, simplifying the system while maintaining precision.
Solution Approach 2:
The patent replaces the mechanical/system-dependent approach of continuous radio link monitoring with a sensor-based approach using motion sensing circuitry and location services. This substitution uses fundamentally different measurement mechanisms (accelerometers, GPS) to infer cellular availability, reducing radio resource complexity while maintaining indication accuracy.
3Measurement precision
If the wireless device uses motion and location information to determine availability indication, then the accuracy is improved, but the device complexity increases
Solution Approach 1:
Motion sensing circuitry and location services are multi-functional components already present in modern wireless devices for various purposes (step counting, fitness tracking, navigation). By repurposing these existing universal components for millimeter wave availability indication, the system gains accuracy without adding dedicated hardware complexity.
