Device Cooperation Service Execution with Disconnected Device Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional device cooperation service systems only support cooperation between devices currently connected to a home network, failing to account for devices that have been disconnected or are not continuously connected, leading to incomplete service provision and potential security risks.
Innovation Solution
A device cooperation service execution apparatus that retrieves and manages devices on a local network, obtains service information for both connected and disconnected devices, and displays a list of available services, preventing unintended operations and enhancing user awareness of device ownership and connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system only retrieves devices currently connected to the home network, then the device retrieval process is simple and fast, but the service coverage is incomplete and cannot support disconnected devices
Solution Approach 1:
The system performs preliminary actions by recording device information in advance when devices are connected to the network. The device information management unit stores device identifiers and service capability information locally, creating a historical record that enables later identification of disconnected devices without requiring real-time network retrieval for each device.
Solution Approach 2:
The patent introduces an external server as an intermediary to manage the complexity of device coordination. The server stores comprehensive device cooperation service information and performs the complex task of determining which services can be executed with available devices, freeing the local system from complex retrieval and matching logic while still enabling comprehensive service coverage.
2Adaptability or versatility
If the system supports cooperation with disconnected devices, then service availability improves, but security risks increase due to potential unauthorized operations
Solution Approach 1:
The system implements feedback mechanisms where the service list display unit continuously monitors the connection status of required devices and provides feedback to the user interface. When a disconnected device is detected as required for a service, the system notifies the user and prevents service execution, creating a closed-loop safety mechanism that maintains security while enabling broad service availability.
Solution Approach 2:
The patent applies preliminary anti-action by proactively identifying and preventing potential security issues before they can cause harm. The system checks whether all required devices are connected before allowing service execution, and explicitly prevents operations involving disconnected devices, thereby neutralizing security risks in advance rather than reacting to them after they occur.
3Loss of information
If the system displays all available services including those requiring disconnected devices, then user awareness of service options improves, but user confusion increases due to unavailable options
Solution Approach 1:
The patent applies local quality by differentiating the display treatment of services based on their availability status. Services that can be executed with currently connected devices are displayed normally, while services requiring disconnected devices are displayed with distinct visual indicators (such as grayed-out appearance or warning icons). This localized differentiation maintains complete information presentation while guiding user attention to actionable options.
Solution Approach 2:
The service list display unit provides real-time feedback to users about the availability status of each service option. When a user hovers over or selects a service, the system checks connection status and provides immediate feedback indicating whether the service can be executed or if disconnected devices are required. This feedback loop enables informed user decision-making without obscuring any service options.
Data Source
AI summary
An application information acquisition unit transmits a device list of unconnected devices, which are owned devices recorded in a local storage but not retrieved by a device retrieval unit, and connected devices, which are owned devices retrieved by the device retrieval unit, to an external server via an external network. A service list display unit displays a list of device cooperation services indicated in device cooperation service list information obtained by the application information acquisition unit from the external server and a list of devices determined to be owned devices by an owned device management unit on a display unit, whereby a user is prompted to select a device cooperation service.
