Innovation Solution
An electronic device equipped with both a 4G modem and a 5G modem, where the processor controls the switching between operation modes by deactivating unnecessary components, establishing new data paths, and rebooting the 5G modem to optimize power usage and communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device maintains both first and second modems active for switching between operation modes, then the device can provide seamless mode switching capability, but the power consumption increases due to maintaining multiple active components
Solution Approach 1:
The patent implements dynamic configuration of data paths between the processor and modems based on the current operation mode. When switching from NSA mode to SA mode, the system dynamically reconfigures the data path to connect the processor directly to the second modem, eliminating the need to maintain both modems active simultaneously and reducing power consumption while preserving switching capability.
Solution Approach 2:
The system changes the operational parameters of the modems by deactivating the first modem when not needed in SA mode and rebooting the second modem to optimize its operation. This parameter change allows the device to maintain mode switching capability while reducing power consumption by having only the necessary modem active at any given time.
2Use of energy by moving object
If the electronic device deactivates the first modem when switching to second mode, then the power consumption is reduced, but the data path establishment becomes more complex requiring reconfiguration
Solution Approach 1:
The patent implements preliminary action by pre-establishing the data path configuration for SA mode before actually switching to it. The system prepares the necessary connections and settings in advance, so when mode switching occurs, the data path can be quickly reconfigured without complex real-time calculations or multiple trial attempts, reducing the perceived complexity during the transition.
Solution Approach 2:
The processor acts as an intermediary that manages the data path reconfiguration process. When switching from NSA to SA mode, the processor mediates between the deactivated first modem and the active second modem, orchestrating the data path changes and ensuring smooth transition without requiring complex coordination between multiple active components.
3Productivity
If the second modem is rebooted during mode switching, then the modem operates more efficiently in the new mode, but the switching time increases due to the reboot process
Solution Approach 1:
The system performs preliminary actions by maintaining the second modem in a ready state with its data path pre-configured, even before switching from NSA mode. This allows the modem to be quickly activated without requiring a full reboot, as only necessary components need to be initialized, significantly reducing the switching time while maintaining operational efficiency.
Solution Approach 2:
Instead of performing a complete reboot, the system applies parameter changes to the second modem's operational state. By modifying specific parameters such as activation status and data path routing rather than resetting the entire modem, the system achieves efficient operation in SA mode with minimal time loss during the switching process.
