Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If simultaneous uplink communication with LTE and NR base stations is performed, then communication productivity is improved, but temperature increases due to overheating
Solution Approach 1:
The patent applies dynamics by enabling the user equipment to dynamically adjust its transmission capability based on real-time thermal conditions. The circuitry monitors temperature and dynamically modifies uplink transmission parameters or selects appropriate base stations, allowing the system to adapt between high productivity modes and thermal protection modes as needed.
2Productivity
If simultaneous uplink communication with LTE and NR base stations is performed, then communication productivity is improved, but reliability deteriorates due to intermodulation products interfering with LTE receivers
Solution Approach 1:
The patent implements feedback mechanisms where the user equipment monitors communication quality and thermal conditions, then provides feedback to the network. This feedback loop enables the system to detect intermodulation interference and adjust transmission parameters or switch base stations accordingly, maintaining reliability while preserving productivity.
Solution Approach 2:
The patent introduces an intermediary approach by having the user equipment's circuitry act as a mediator between the transmission system and the receiving system. The circuitry detects thermal conditions and intermodulation products, then mediates the conflict by adjusting transmission parameters or selecting alternative communication paths to protect the LTE receiver from interference.
3Temperature
If uplink configuration is adjusted to prevent overheating, then temperature is controlled, but communication productivity decreases
Solution Approach 1:
The patent applies parameter changes by modifying transmission parameters such as power levels, modulation schemes, or selected base stations based on thermal conditions. The circuitry changes these parameters dynamically to prevent overheating while minimizing impact on communication productivity, allowing the system to operate at optimal points across the temperature-performance trade-off curve.
