Lock Screen Control Widget for IoT Device Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users need to unlock their mobile device and open an application to control other electronic devices, which complicates the process of performing operations like changing TV channels or adjusting volume, especially when the device is in a lock screen state.
Innovation Solution
A method and apparatus that display a control widget on the lock screen, allowing users to detect trigger operations and send control instructions to connected devices without unlocking the device, enabling direct execution of predetermined operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user unlocks the mobile device and opens an application to control other electronic devices, then the control operation can be executed, but the operation process becomes complicated and time-consuming
Solution Approach 1:
The patent segments the control functionality from the main application by introducing a control widget that operates independently on the lock screen. This widget provides a simplified interface for device control without requiring full application launch, thereby reducing operational steps and time consumption while maintaining control capabilities.
Solution Approach 2:
The control widget is prepared and displayed in advance on the lock screen, allowing users to access device control functions immediately without needing to unlock the device and navigate through applications. This preliminary arrangement of control interfaces eliminates the time required for unlocking and application opening.
2Ease of operation
If the control widget is displayed on the lock screen, then the user can control devices without unlocking, but the lock screen functionality becomes more complex
Solution Approach 1:
The patent extracts the essential device control functionality from the full application and places it in a separate control widget on the lock screen. This extraction allows the lock screen to provide control capabilities without incorporating the entire application's complexity, maintaining a balance between functionality and simplicity.
Solution Approach 2:
The control widget provides localized control functionality specifically on the lock screen interface, differentiating it from the full application. This local implementation allows users to perform common control operations without unlocking, while the full application remains available for more complex operations, thus managing overall system complexity.

AI summary
Methods and apparatuses are provided for controlling a device. In the method, the electronic device displays a control widget corresponding to the at least one device in a lock screen. When a trigger operation on the control widget is detected, the electronic device determines a control instruction corresponding to the control widget. The electronic device sends the control instruction to the at least one device, in which the control instruction is configured to instruct the at least one device to execute a predetermined operation corresponding to the control instruction.
