Rule Engine Device Linkage Without Scene Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current device linkage mechanisms are complex and require additional capabilities from server devices, making it difficult to implement efficient device linkage between Internet of Things (IoT) devices, especially in resource-constrained environments, and do not simplify the process of establishing connections between rule input and output resources.
Innovation Solution
A device linkage method where a rule engine device receives a request message from a client to establish a connection relationship with a rule input or output server device, allowing for device linkage without relying on scene resources, thereby reducing complexity and performance requirements for linked devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a traditional OCF linkage rule engine is used to implement device linkage, then device linkage functionality is achieved, but the complexity of the linkage mechanism increases and performance requirements for linked devices increase
Solution Approach 1:
The patent extracts the scene resource dependency from the device linkage mechanism. By allowing rule input and output resources to be directly linked without requiring scene resources as intermediaries, the complexity associated with scene resource management is removed while preserving the core device linkage functionality.
Solution Approach 2:
The patent segments the device linkage mechanism into independent rule input resources and rule output resources that can be directly connected. This segmentation eliminates the need for hierarchical scene resource structures, simplifying the overall linkage mechanism while maintaining functional integrity.
2Adaptability or versatility
If scene resources are required for device linkage, then linkage rules can be established, but the performance requirements for server devices increase
Solution Approach 1:
The patent removes the mandatory requirement for scene resources in device linkage operations. By enabling direct connections between rule input and output resources, the system eliminates the additional computational and storage overhead that scene resources impose on server devices.
Solution Approach 2:
The patent replaces complex scene resource structures with simpler, lightweight rule input and output resource connections. This substitution reduces the computational burden on server devices while maintaining the necessary linkage functionality.
3Ease of operation
If scene resources are used as intermediaries for device linkage, then resource coordination is achieved, but the process of establishing connections becomes more complex
Solution Approach 1:
The patent extracts the intermediate scene resource layer from the connection establishment process. By allowing direct peer-to-peer connections between rule input and output resources, the patent simplifies the operational process while reducing the structural complexity of the linkage mechanism.
