Mobile Terminal Display Splitting for Simultaneous Navigation and Call Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication terminals terminate the navigation service when a call is received while navigation is in use, causing inconvenience and making it impossible to receive both call and navigation services simultaneously.
Innovation Solution
A mobile communication terminal that displays call connection state information on the screen while a navigation service is running, either by overlaying a call reception window on the navigation screen or splitting the screen to show route guidance and call connection information separately, allowing users to manage calls without disrupting navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the navigation service is terminated to answer an incoming call, then the call connection is established, but the navigation service must be restarted from the beginning causing inconvenience
Solution Approach 1:
The patent segments the display screen into multiple regions, with one region dedicated to navigation service display and another region for call connection interface. This allows both services to operate simultaneously without interruption, as each service occupies a separate display segment. The navigation service continues in its designated region while the call interface appears in another region, eliminating the need to terminate navigation for call reception.
2Duration of action of stationary object
If the navigation service continues running during an incoming call, then navigation continuity is maintained, but the call connection interface cannot be displayed
Solution Approach 1:
The patent transitions from a single-dimensional display approach (one service at a time) to a multi-dimensional display approach by utilizing multiple display regions simultaneously. The navigation service occupies one display region while the call connection interface occupies another region, allowing both services to be accessed and operated on the same screen without overlapping or interfering with each other.
3Adaptability or versatility
If the screen is split to display both navigation and call information, then both services can be accessed simultaneously, but the display region is divided
Solution Approach 1:
The patent applies local quality by assigning different display regions with different functional qualities - one region optimized for navigation information display with appropriate size and positioning, and another region for call interface elements. Each region maintains its own characteristics and optimization for its specific service, allowing both services to function effectively despite the screen division.

AI summary
A method for controlling an electronic device comprises performing a first function and displaying a screen of the electronic device corresponding to the first function, receiving an incoming call, displaying a window on a portion of the screen in response to the reception of the incoming call, the window displaying predetermined information relating to the incoming call, receiving a control signal from a user of the electronic device, and performing a second function in response to the reception of the control signal.
