Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless communication technologies and features are integrated into UE devices, then device functionality and performance are improved, but battery power consumption increases
Solution Approach 1:
The patent implements dynamic RAT prioritization where the UE automatically adjusts its preferred radio access technology based on real-time conditions including signal strength, network load, battery status, and service requirements. This dynamic adaptation allows the system to optimize power consumption while maintaining functionality by switching between different RATs (e.g., 5G NR, LTE, Wi-Fi) depending on current operational needs and environmental factors.
Solution Approach 2:
The system changes operational parameters by modifying RAT selection criteria based on varying conditions such as signal quality thresholds, battery charge levels, network availability, and service type requirements. The prioritization parameters are adjusted dynamically to balance between power saving modes and performance-critical modes, allowing the UE to adapt its communication strategy based on current system state and user needs.
2Use of energy by moving object
If radio access technology prioritization is dynamically adjusted, then power consumption is reduced, but service availability and communication reliability may be impacted
Solution Approach 1:
The patent implements feedback mechanisms where the UE continuously monitors service availability, signal quality, and network response to validate whether prioritization decisions maintain reliable service. If deprioritizing a RAT results in service unavailability or excessive latency, the system receives feedback and reverses the prioritization decision. This feedback loop ensures that power saving measures do not compromise essential service reliability.
Solution Approach 2:
The system performs preliminary assessment of service availability and network conditions before finalizing RAT prioritization decisions. By evaluating factors such as network load, signal strength thresholds, and service requirements in advance, the system prevents premature or inappropriate deprioritization that could disrupt service availability. This preliminary action ensures that power consumption optimization does not come at the cost of unreliable service.
