IoT Device Management via RESTful Resource Model Abstraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IoT device management technologies face challenges in efficiently managing large networks of interconnected IoT devices, particularly in defining and implementing device management services, resource abstraction, and dynamic provisioning, which limits flexibility and scalability.
Innovation Solution
The implementation of a resource model abstraction that allows for the definition and use of device management services based on RESTful messaging and a data model that utilizes core device definition building blocks, enabling dynamic instantiation and management of IoT device services, as well as the creation of arrays of devices and resources for complex operations.

Engineering Contradiction Analysis
1Adaptability or versatility
If traditional IoT device management technologies are used, then device management functionality is provided, but flexibility and scalability are limited when managing large networks of interconnected IoT devices
Solution Approach 1:
The patent segments device management services into reusable service templates that can be independently defined, configured, and instantiated. Each service template represents a modular unit of management functionality that can be composed and deployed separately, enabling flexible assembly of complex management solutions without increasing overall system complexity.
Solution Approach 2:
The patent creates universal service templates that can be instantiated multiple times across different devices and contexts. These templates provide multi-functional capabilities that can adapt to various IoT device types and management scenarios, enhancing flexibility while maintaining consistent management patterns through standardized template definitions.
2Adaptability or versatility
If traditional IoT device management technologies are used, then basic device management is achieved, but dynamic provisioning and service instantiation are limited
Solution Approach 1:
The patent implements preliminary action by pre-defining service templates with all necessary configuration parameters, interfaces, and behavior specifications before deployment. This allows services to be dynamically instantiated and provisioned on-demand without requiring complex runtime configuration or manual setup, enhancing both dynamic provisioning capability and ease of operation.
Solution Approach 2:
The patent uses copying by creating instances from service templates. The template serves as a reusable blueprint that can be copied and instantiated multiple times across different devices and contexts, enabling rapid dynamic provisioning while maintaining consistent service definitions and reducing operational complexity.
3Adaptability or versatility
If device management services are defined with clear service behavior, then service instantiation flexibility is improved, but the complexity of defining and implementing these services increases
Solution Approach 1:
The patent applies parameter changes by defining service templates with configurable parameters that can be adjusted during instantiation. This allows the same service template to adapt to different contexts and requirements by changing parameters rather than creating entirely new service definitions, thereby improving instantiation flexibility while keeping the base template definition manageable.
