Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If static and preset UL path configuration is used, then device complexity is reduced and ease of operation is improved, but power efficiency deteriorates and uplink performance worsens
Solution Approach 1:
The patent implements dynamic UL path configuration that automatically adjusts the primary UL path between MCG and SCG based on real-time UL path quality measurements. The system transitions from static preset configuration to dynamic adaptive configuration, where the primary UL path is determined by comparing LTE and NR UL path qualities against thresholds and selecting the optimal path based on current network conditions, thereby improving power efficiency without significantly increasing operational complexity
Solution Approach 2:
The patent employs feedback mechanisms where UL path quality is continuously measured and evaluated against predetermined thresholds. The system uses timer conditions and quality comparisons to determine when to switch primary UL paths, creating a closed-loop control system that adapts to changing network conditions. This feedback-driven approach enables automatic optimization of power efficiency based on actual UL path performance
2Device complexity
If static and preset UL path configuration is used, then device complexity is reduced, but uplink performance deteriorates
Solution Approach 1:
The system transitions from static to dynamic UL path configuration, automatically selecting the primary UL path based on real-time quality measurements. The patent implements dynamic path selection between MCG and SCG using timer conditions and quality thresholds, enabling the system to adapt to changing network conditions and optimize uplink performance without requiring complex manual configuration
Solution Approach 2:
The patent enables the UL path configuration system to self-optimize by automatically measuring UL path quality, comparing it against thresholds, and selecting the optimal primary UL path without external intervention. The system uses embedded timer conditions and quality evaluation logic to autonomously manage path selection, improving uplink performance while keeping device complexity manageable through automated decision-making
3Use of energy by moving object
If dynamic UL path determination is implemented, then power efficiency is improved and uplink performance increases, but device complexity increases
Solution Approach 1:
The patent segments the UL path management into distinct functional components: quality measurement, threshold comparison, timer condition evaluation, and path selection. By dividing the dynamic path determination process into modular segments with clear responsibilities, the system achieves sophisticated power optimization while managing complexity through structured organization of management functions
Solution Approach 2:
The patent manages complexity by focusing on changing key parameters (UL path quality, threshold values, timer conditions) rather than redesigning the entire system. The dynamic determination mechanism adjusts specific parameters like primary UL path selection and quality thresholds while maintaining the overall architectural framework, thereby improving power efficiency without proportionally increasing device complexity
4Productivity
If dynamic UL path determination is implemented, then uplink performance is improved, but user of energy increases due to continuous monitoring
Solution Approach 1:
The patent implements periodic UL path quality monitoring using timer conditions rather than continuous monitoring. The system evaluates UL path quality at predetermined intervals defined by timer thresholds, reducing the energy consumption associated with constant monitoring while maintaining effective uplink performance optimization. This periodic approach balances performance improvement with energy conservation
