Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IoT device management systems are inefficient, error-prone, and insecure, requiring manual configuration and administration, which increases costs and security risks, and demands technical expertise.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration and administration operations are performed on each IoT device, then device configuration and management can be accomplished, but productivity decreases and operational costs increase
Solution Approach 1:
The patent segments the device management process into two distinct planes: the control plane (for configuration and management operations) and the data plane (for actual device data traffic). This segmentation allows centralized SDN controller to handle control operations for multiple devices simultaneously, while device data flows remain independent, thereby improving management productivity without compromising individual device configurability
Solution Approach 2:
The SDN overlay network acts as an intermediary layer between administrators and IoT devices. Instead of directly configuring each device individually, administrators interact with the SDN controller, which then translates and distributes configuration operations across multiple devices automatically, significantly enhancing management efficiency
2Ease of operation
If direct connections and raw configuration operations are performed on IoT devices, then device administration can be executed, but security vulnerabilities increase
Solution Approach 1:
The SDN overlay network serves as a secure intermediary between administrators and IoT devices. All configuration operations pass through the SDN controller, which authenticates and authorizes access before translating commands to device-specific protocols. This eliminates direct administrator-device connections, reducing security exposure while maintaining administrative capability
Solution Approach 2:
The patent extracts security-critical control plane functions from the data plane by implementing an SDN overlay. This separation removes sensitive configuration operations from direct device access, isolating security vulnerabilities to the overlay layer while protecting underlying IoT devices from direct exposure to administrative operations
3Ease of operation
If traditional OAM operations are performed on IoT devices, then device management can be achieved, but operational costs increase and ROI decreases
Solution Approach 1:
The patent merges the management of multiple diverse IoT devices into a single unified SDN overlay network. This consolidation allows administrators to manage numerous devices through one interface, reducing operational overhead and costs while maintaining full device functionality and configurability
