Mobile Terminal Setting Screen Synchronization for Connected Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when connecting smartphones to larger screen devices, as they need to change settings before or after connection, which can be bothersome due to differences in screen size, resolution, and hardware resources, making it difficult to set optimal settings for the connected devices.
Innovation Solution
A setting system and method that displays a setting screen on both the mobile terminal and the connected display device, allowing users to change settings directly on the larger screen, eliminating the need for pre- or post-connection setting changes by automatically synchronizing settings through an interface that includes setting items for screen size, resolution, and other parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the smartphone is connected to a larger screen device, then the display area is improved, but the ease of operation deteriorates because the user cannot use the smartphone's input section to change settings
Solution Approach 1:
The patent introduces a setting screen that is displayed on the connected larger screen device (TV, monitor, etc.) and operated through the smartphone's display. This intermediary interface allows users to change smartphone settings (silent mode, vibration mode, screen size) by viewing and interacting with the setting options on the larger screen, eliminating the need to use the smartphone's small input section while the device is connected.
2Ease of operation
If the user changes settings before connection, then the ease of operation is improved, but the adaptability deteriorates because the user cannot adjust settings based on the actual connected device
Solution Approach 1:
The patent implements preliminary action by automatically detecting when a connected device is connected and immediately displaying an appropriate setting screen on that device. This allows users to make setting changes (such as adjusting silent mode, vibration mode, or screen size) after connection based on the actual device characteristics, rather than requiring pre-connection configuration. The system prepares the setting interface in advance upon detection of connection, enabling timely adjustments.
3Ease of operation
If the setting screen is displayed on the connected device, then the ease of operation is improved, but the device complexity increases due to the interface mechanism
Solution Approach 1:
The patent applies universality by designing a setting screen that can be displayed on multiple types of connected devices (TV receivers, monitors, projectors, etc.) through their existing display interfaces. The same setting screen format and control mechanism work across different device types, eliminating the need for device-specific interface implementations. This universal approach allows the smartphone to operate as a remote control for various connected devices without increasing interface complexity.

AI summary
A setting system including a mobile terminal having an interface with an external device so as to transmit and receive information therebetween; and a display device having the interface with the mobile terminal so as to transmit and receive information therebetween, a display section whose screen size is larger than the mobile terminal, and an input section to which the user can input information. When the mobile terminal and the display device are connected through the interface, the mobile terminal and the display device display a setting screen that includes a setting item that sets at least the state of the mobile terminal such that the user can change a setting for the mobile terminal on the setting screen.
