Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-screen collaborative system uses conventional Wi-Fi networking mode, then device connectivity is maintained, but data transmission performance is poor due to lack of dual band dual concurrent capability
Solution Approach 1:
The patent segments the data transmission path into two independent parts: a first link for internet access through the access point, and a second link for multi-screen collaboration between devices. This segmentation allows each link to operate independently on different frequency bands, resolving the contradiction by enabling simultaneous internet access and device collaboration without performance degradation from shared bandwidth constraints.
Solution Approach 2:
The patent introduces a frequency band switching mechanism as an intermediary to dynamically adjust the operating frequency between the first link (internet access) and the second link (device collaboration). This intermediary allows the system to optimize data transmission performance by selecting the best frequency band for each specific transmission task, overcoming the limitation of fixed conventional Wi-Fi modes.
2Productivity
If frequency band switching is implemented to optimize data transmission, then transmission efficiency improves, but system complexity increases
Solution Approach 1:
The patent implements dynamic frequency band switching that automatically adjusts the operating frequency based on real-time transmission requirements and network conditions. The system dynamically selects between first and second frequency bands for different links, optimizing data transmission efficiency without requiring manual intervention or complex user configuration, thus managing the complexity through automation.
Solution Approach 2:
The frequency band switching mechanism operates autonomously, with the system automatically determining when and how to switch frequency bands based on detected transmission conditions. This self-service approach eliminates the need for users to manually manage frequency configurations, reducing the perceived complexity while maintaining high transmission efficiency through intelligent automated control.

AI summary
This application provides a data transmission management method, an electronic device, and a storage medium, and relates to the field of intelligent terminals. The method is applied to a first electronic device that has a first link with a wireless access point. The method includes: determining, in response to a user operation, a second electronic device that performs data transmission with the first electronic device, where a second link exists between the second electronic device and the wireless access point; establishing a third link configured to perform data transmission with the second electronic device; and when a first preset condition is met, establishing a fourth link connected to the second electronic device and disconnecting the first link; or when a first preset condition is met, establishing a fourth link connected to the second electronic device and maintaining the first link, where a frequency band in which the third link is located is different from a preset frequency band.
