Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a single UWB channel is used for communication, then device complexity is reduced, but service delay increases when multiple users are present
Solution Approach 1:
The patent divides the UWB communication resource into multiple channels (first UWB channel and second UWB channel) to serve different users simultaneously. The first UWB channel is used for communication with a first electronic device, while the second UWB channel is used for communication with a second electronic device, thereby reducing service delay through channel segmentation.
Solution Approach 2:
The patent implements dynamic channel selection where the electronic device can switch between different UWB channels based on which device is ready for communication. The system dynamically assigns the first UWB channel or second UWB channel depending on the communication status and readiness of different electronic devices, optimizing service delivery without requiring complex fixed allocation.
2Productivity
If multiple UWB channels are operated simultaneously, then service delivery efficiency for multiple users is improved, but device complexity increases
Solution Approach 1:
The patent establishes UWB channel information in advance during the connection phase between the server and electronic devices. The server pre-configures which UWB channels will be used for communication with specific devices, so that when communication is needed, the devices can immediately use the predetermined channels without complex real-time negotiation, thereby improving service delivery efficiency while managing complexity through advance planning.
3Speed
If UWB communication is activated without BLE trigger, then communication speed is faster, but power consumption increases
Solution Approach 1:
The patent uses BLE (Bluetooth Low Energy) advertisement messages to pre-establish connection information and trigger UWB communication only when necessary. The BLE connection serves as a low-power preliminary step that exchanges initial data, and UWB communication is activated selectively based on the BLE-triggered conditions, thereby maintaining fast communication speed when needed while avoiding unnecessary power consumption through conditional activation.

AI summary
A method for operating a plurality of ultra-wide band (UWB) channels by a first electronic device is provided. The method includes receiving a Bluetooth low energy (BLE) advertisement message including information about an UWB channel, from a second electronic device, identifying whether a plurality of UWB channels are operated, based on the information about the UWB channel, and identifying a UWB channel to be used for communication with the second electronic device, based on the information about the UWB channel. The information about the UWB channel may include flag information indicating an area and channel information indicating a UWB channel for the indicated area.
