Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If 5G modem chip is integrated with existing 4G/3G modem chips into one chip, then device complexity is reduced, but manufacturing precision and reliability deteriorate due to different radio frequency characteristics
Solution Approach 1:
The patent divides the modem system into separate 4G/3G modem chip and 5G modem chip, each optimized for their specific radio frequency characteristics. The 4G/3G modem chip handles legacy networks while the 5G modem chip handles mmWave frequencies, avoiding integration conflicts and maintaining manufacturing precision for each specific frequency band.
Solution Approach 2:
The application processor serves as an intermediary between the 4G/3G modem chip and the 5G modem chip. It manages power control, data transfer, and coordination between the two separate modem chips, enabling them to work together without direct integration while maintaining their distinct radio frequency optimizations.
2Device complexity
If 5G modem chip is integrated with existing modem chips, then hardware structure is simplified, but adaptability deteriorates due to undefined interworking structure
Solution Approach 1:
The application processor is designed with universal functionality to manage both 4G/3G and 5G modem operations. It can control power states, transfer data, and coordinate operations between different modem chip types, providing adaptability across multiple wireless communication standards without requiring dedicated control logic for each modem type.
Solution Approach 2:
The system employs dynamic power management where the application processor can independently power on/off the 5G modem chip based on network conditions. The interworking structure allows flexible adaptation between different operational modes (4G only, 5G only, or both) depending on signal quality and data requirements.
3Reliability
If separate modem chips are used for 4G/3G and 5G, then reliability is improved through optimized hardware configurations, but device complexity increases
Solution Approach 1:
The application processor acts as a central mediator that manages the complexity of having separate 4G/3G and 5G modem chips. It handles power control, data routing, and coordination between the separate chips, abstracting the complexity away from the user and maintaining reliable communication across different network types.
Solution Approach 2:
While keeping the 4G/3G and 5G modem chips separate for optimization, the patent merges their control and management functions into the application processor. This consolidation of control logic compensates for the hardware separation, maintaining system reliability while managing the complexity of multiple modem chips.
4Use of energy by moving object
If power control is implemented between modem chips, then energy efficiency is improved, but control complexity increases
Solution Approach 1:
The application processor autonomously manages power control for the 5G modem chip based on real-time network conditions and data requirements. It can independently decide when to power on/off the 5G modem without requiring manual intervention or complex external control circuits, achieving energy efficiency through self-service power management.
Solution Approach 2:
The system implements feedback-based power control where the application processor monitors network signal quality and data traffic patterns, then adjusts the power state of the 5G modem chip accordingly. When signal quality is poor or data requirements are low, the 5G modem is powered off to save energy; when conditions improve, it is powered on to utilize 5G capabilities.
