Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT systems face issues such as communication loss and service delays between electrical devices and server apparatuses, which can disrupt the provision of services.
Innovation Solution
An edge device linking system that enables communication and service provision between edge devices without the need for direct communication with a server apparatus, utilizing device information management and service provision mechanisms to control operations based on event and action information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical devices communicate with server apparatus through edge devices, then services can be provided via IoT platform, but communication loss and service delays occur
Solution Approach 1:
The patent introduces a service information management table stored in each edge device that acts as a local intermediary for service provisioning. Instead of requiring all service operations to communicate through the cloud server, edge devices can directly process service requests using locally stored service information (event information and action information), thereby reducing communication delays and improving reliability by eliminating single-point communication failures.
2Ease of operation
If all service processing is centralized on server apparatus, then service management is unified, but communication dependency increases and real-time control is reduced
Solution Approach 1:
The patent segments service processing functionality by distributing service information (event information and action information) to multiple edge devices. Each edge device independently stores and executes service logic locally, eliminating the need for centralized server processing for routine service operations. This segmentation enables parallel service execution across multiple edge devices, significantly improving real-time control capability while maintaining ease of operation through standardized service information formats.
3Productivity
If edge devices directly control electrical devices without server communication, then real-time control is improved, but service management complexity increases
Solution Approach 1:
The patent transforms complex service management into a standardized parameter-based system. Service information is structured with specific parameters including event information (trigger conditions) and action information (execution commands). By changing the management approach from centralized complex logic to standardized parameter storage and matching, edge devices can independently handle service operations without increasing operational complexity. The standardized format enables automatic parameter matching and execution, simplifying what would otherwise be complex distributed service management.

AI summary
An adapter device (200-1) includes a device information manager (201) to manage device information with respect to an electrical device (300-1), and a service provider (202) to manage service information and provide the service based on service information. The service information indicates content of the service and includes action information indicating an operation of an electrical device (300-2) and event information indicating a condition for executing the operation indicated by the action information. An adapter device (200-2) includes a controller (203) to control the operation of the electrical device (300-2). Upon determining that the device information with respect to the electrical device (300-1) satisfies the condition indicated by the event information, the service provider (202) causes the controller (203) to control the electrical device (300-2) to perform the operation indicated by the action information.
