Engineering Contradiction Analysis
1Productivity
If 5G frequency band is used for wireless communication, then data transmission rate and bandwidth are improved, but signal coverage distance is reduced and signal strength decreases
Solution Approach 1:
The patent implements dynamic frequency band switching between 2.4G and 5G based on real-time signal strength detection and service state assessment. The system transitions from static single-band operation to dynamic multi-band adaptation, allowing the communication mode to change according to environmental conditions and service requirements.
Solution Approach 2:
The patent changes the operating frequency band parameter from fixed to variable, selecting between 2.4G and 5G bands based on signal strength and service state. This parameter adaptation allows the system to optimize between coverage distance and transmission rate by choosing the appropriate frequency band for current conditions.
2Length of moving object
If 2.4G frequency band is used for wireless communication, then signal coverage distance is improved, but signal interference increases and network rate decreases
Solution Approach 1:
The system dynamically switches between 2.4G and 5G frequency bands based on detected signal interference levels and service state. When interference is detected on 2.4G, the system transitions to 5G band, and vice versa, allowing adaptive avoidance of harmful interference conditions while maintaining coverage capabilities.
Solution Approach 2:
The patent introduces signal strength detection and service state assessment as intermediary mechanisms that mediate between the conflicting requirements of coverage distance and interference avoidance. These intermediaries evaluate current conditions and determine the optimal frequency band selection.
3Device complexity
If single frequency band is used for communication, then device complexity is reduced, but communication reliability deteriorates under varying signal conditions
Solution Approach 1:
The patent implements multi-functionality by enabling the communication device to operate on both 2.4G and 5G frequency bands, making the system universal across different frequency environments. This multi-band capability allows the device to adapt to varying signal conditions and maintain reliability across diverse operational scenarios.
Solution Approach 2:
The system dynamically adjusts its operational mode between single-band and dual-band based on service state and signal conditions. The complexity is introduced only when needed for reliability, and reduced when not necessary, optimizing the trade-off between device complexity and communication reliability.
4Productivity
If 5G frequency band is used for high-speed data transmission, then bandwidth is improved, but signal attenuation increases and connection stability decreases
Solution Approach 1:
The patent implements dynamic monitoring and switching between 2.4G and 5G bands based on signal strength and service state. When 5G signal attenuation becomes excessive, the system transitions to 2.4G band to maintain connection stability, and vice versa when high bandwidth is needed and signal conditions permit.
Solution Approach 2:
The system performs beforehand cushioning by proactively switching frequency bands before complete connection failure occurs. When signal strength drops below thresholds or service state indicates degradation, the system preemptively transitions to the other frequency band to prevent connection instability and service interruption.

AI summary
A method includes a first electronic device that detects a signal strength when the first electronic device communicates with a second electronic device, and determines whether the signal strength is less than a preset value. When the signal strength is less than the preset value, the first electronic device determines a current service state of the second electronic device, and determines, based on the current service state, working modes including a first working mode and a second working mode that respectively correspond to the first electronic device and the second electronic device and that are suitable for the current service state. The first electronic device switches a working mode of the first electronic device to the determined first working mode, and sends an instruction to indicate to the second electronic device to switch a working mode of the second electronic device to the second working mode.
