Communication Device Screen Switching Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face issues in determining the appropriate external device for operations when multiple connections are established, leading to unintended switching of data communication targets.
Innovation Solution
A communication device and method that utilize multiple connection methods, such as Bluetooth and Wi-Fi, to determine whether to automatically display a screen for an external device based on the connection method and whether the device is newly connected or reconnected, ensuring user-intended device operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic switching of data communication target is implemented when a connection is established, then connection efficiency is improved, but accuracy of data communication target selection deteriorates
Solution Approach 1:
The patent changes the parameter of screen display behavior based on connection method. When a new connection method is detected (e.g., switching from wired to wireless), the system automatically displays the screen for the newly connected external device. However, when the same connection method is used again (reconnection), the system maintains the current screen without automatic switching. This parameter change resolves the contradiction by making automatic switching selective rather than universal.
Solution Approach 2:
The patent introduces dynamic behavior where the automatic screen switching is enabled only under specific conditions (new connection methods) and disabled under other conditions (reconnections). The system dynamically adjusts its response based on whether the connection represents a new communication path or a reuse of an existing one, thereby maintaining accuracy while preserving efficiency where appropriate.
2Ease of operation
If automatic screen switching is implemented for all connections, then user convenience is improved, but user control and intent accuracy deteriorate
Solution Approach 1:
The patent modifies the automatic screen switching parameter based on connection method type. It enables automatic switching for new connection methods to enhance convenience, but disables it for reconnections to preserve user intent accuracy. This selective parameter adjustment allows the system to be convenient without being overly aggressive in screen switching.
Solution Approach 2:
The system uses feedback about the connection state (whether it's a new connection method or a reconnection) to determine appropriate screen switching behavior. This feedback mechanism allows the system to adapt its automatic switching behavior to match user expectations, thereby maintaining reliability while providing convenience where appropriate.

AI summary
A communication device that communicates with an external device using a first connection method and a second connection method is disclosed. The communication device, when a connection is established with an external device, determines whether to automatically display a screen for using the external device from the communication device on a display device, based on (i) a connection method used to connect to the external device and/or (ii) whether the external device is newly connected or reconnected.
