Wireless Disconnection Display Logic for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with wireless communication functions often display unnecessary user confirmation messages when a wireless connection is disconnected, requiring users to manually confirm disconnections caused by external device requests, even if the device is not readily accessible, such as when it is in a bag.
Innovation Solution
An electronic device with a processor and wireless communication interface that determines the cause of disconnection and displays different types of disconnection screens based on whether the disconnection was requested by an external device, allowing for automatic confirmation if the disconnection was due to an external request and requiring user confirmation otherwise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a message is displayed on the display unit regardless of how the wireless communication was started and regardless of the cause of disconnection, then user confirmation is obtained, but the user needs to take out the electronic device and operate it to confirm the message, which is complicated
Solution Approach 1:
The patent applies local quality by differentiating the display behavior based on the specific cause of disconnection. When disconnection is caused by an external device's request, no display is made. When caused by other factors, a display is made. This localized differentiation resolves the contradiction by providing confirmation only where necessary while avoiding unnecessary operations elsewhere.
Solution Approach 2:
The patent inverts the conventional approach by not displaying a message by default, but rather displaying it only under specific conditions (when disconnection is not due to external device request). This inversion resolves the contradiction by eliminating unnecessary displays that cause operational complexity while maintaining reliability through selective display.
2Reliability
If a message is displayed on the display unit until user confirmation is obtained, then user confirmation is ensured, but the message continues to be displayed even when the electronic device is located in a bag, which is inconvenient
Solution Approach 1:
The patent applies local quality by making the display behavior contingent on the specific cause of disconnection. By determining whether the external device requested disconnection, the system selectively applies confirmation requirements only when appropriate, thereby ensuring reliability without forcing users to retrieve devices from bags for unnecessary confirmations.
Solution Approach 2:
The patent enables self-service by allowing the system to automatically determine the cause of disconnection and make appropriate decisions about displaying confirmation messages. This eliminates the need for users to manually assess situations and ensures that confirmation is only requested when genuinely necessary, improving convenience while maintaining reliability.
3Ease of operation
If different methods for displaying the screen indicating disconnection are used based on whether the disconnection is based on a request from the external device, then unnecessary user interactions are reduced, but the device complexity increases
Solution Approach 1:
The patent applies preliminary action by determining the cause of disconnection before displaying any message. By performing this determination in advance, the system can select the appropriate display method without requiring complex real-time decision logic, thereby reducing user interactions while keeping the control structure manageable through pre-established decision paths.

AI summary
If a wireless connection with an external device is disconnected, it is determined whether or not the disconnection is based on a request from the external device. Different methods for displaying a screen indicating the disconnection are used in the case where it is determined that the disconnection is based on a request from the external device and the case where it is not. Accordingly, it is possible to realize an electronic device that performs suitable indication to a user and a method for controlling the same.
