Communication Device Settings Screen for Protocol Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face cumbersome input operations when selecting communication channels and specifying external devices for communication, particularly when multiple communication protocols like WiFi and Bluetooth are available.
Innovation Solution
A communication device with a display unit and processor executes instructions to display settings screens for selecting communication protocols, search for external devices, and automatically switch between WiFi and Bluetooth protocols based on user input, simplifying the selection process by visually indicating the chosen protocol and facilitating seamless device communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a device is configured to communicate using multiple communication channels (WiFi and Bluetooth), then communication versatility is improved, but the number of input operations required increases
Solution Approach 1:
The communication device automatically detects the communication capability of the external device and selects the appropriate communication channel without requiring manual user input. The device performs self-service by autonomously determining whether to use WiFi or Bluetooth based on device detection, thereby reducing the number of input operations while maintaining multi-channel communication capability
Solution Approach 2:
The device pre-configures multiple communication channels (WiFi and Bluetooth) and prepares them for automatic selection before communication is needed. By having the communication channels ready and configured in advance, the device can quickly switch between them based on external device detection without requiring users to manually set up each communication method
2Ease of operation
If the device provides detailed communication settings options, then user control is improved, but the device complexity increases
Solution Approach 1:
The communication settings are segmented into different levels: a simplified default mode for automatic operation and detailed configuration options for advanced users. The interface divides communication settings into separate modules (WiFi settings, Bluetooth settings) that can be accessed independently, reducing the perceived complexity while maintaining comprehensive control capabilities
Solution Approach 2:
The settings interface dynamically adapts its complexity based on user needs and communication scenarios. The device provides a simple default view that automatically manages communication channels, and only displays detailed configuration options when explicitly requested or when automatic detection fails, making the interface complexity variable rather than fixed

AI summary
A communication device may have multiple units for communicating through multiple channels. The communication device may also include a display for displaying various screens. The communication device may display a function settings screen for selecting a communication unit to be used for communication with an external device. The communication device may determine whether an external device is already specified. The communication device may also display a device search screen identifying one or more external devices that can communicate with a particular communication unit of the communication device. Further, the communication device may display an updated function settings screen that indicates which communication unit is set to be used for communication with an external device and that identifies which external device is to receive communications from such communication unit.
