Dual Wireless Interface Connection Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication devices lack the ability to selectively establish wireless connections with external devices when receiving connection requests from multiple devices simultaneously, leading to potential connection conflicts and inefficiencies.
Innovation Solution
A communication device with two wireless interfaces that prioritizes connections based on the order of connection requests, using one interface to establish a connection with a preferred external device while preventing connections with other devices through the second interface, allowing for user confirmation and control over wireless link establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the communication device receives connection requests from multiple external devices simultaneously, then the device can establish connections with external devices, but connection conflicts occur and the user's intended connection may not be established
Solution Approach 1:
The communication device performs preliminary actions by displaying a standby screen in advance when a connection request is received, allowing the user to confirm and select the intended connection before the actual connection is established. This preliminary user confirmation step ensures that when multiple devices attempt to connect simultaneously, the user's intended connection is prioritized and established reliably.
2Adaptability or versatility
If the communication device establishes connections with multiple external devices, then connection flexibility is improved, but connection conflicts and system instability increase
Solution Approach 1:
The communication device implements feedback by monitoring the timing and status of connection requests from multiple external devices, and by providing visual feedback through the standby screen that shows connection status to the user. This feedback mechanism allows the device to manage multiple connection requests appropriately and maintain system stability while preserving connection flexibility.
3Measurement precision
If the communication device waits for user confirmation before establishing connections, then connection accuracy is improved, but connection establishment time increases
Solution Approach 1:
The communication device uses periodic action by implementing timed operations for processing connection requests. The standby screen is displayed for a specific time period to allow user confirmation, and if no confirmation is received within this period, the device proceeds with default connection logic. This periodic approach balances connection accuracy with time efficiency.

AI summary
A communication device is described as including: a first wireless interface; a second wireless interface; a processor; and a memory storing computer-readable instructions therein, the computer-readable instructions, when executed by the processor, causing the communication device to: receive, via the second wireless interface, a connection request from a first external device; after receiving the connection request from the first external device, establish, via the first wireless interface, a connection with a second external device, wherein the second external device is different from the first external device; transmit information to the second external device, wherein the information prevents the second external device from establishing, via the second wireless interface, a connection with the communication device; and establish, via the second wireless interface, a connection with the first external device.
