Server-Based IoT Device Interworking via Pre-Configured Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing short-range communication technologies face challenges in device interworking, particularly for IoT devices without direct Internet connectivity or camera capabilities, as they require complex registration processes and additional hardware like NFC, leading to increased costs and difficulty in identifying and pairing devices.
Innovation Solution
A server-based system that facilitates interworking between devices by generating and transmitting interworking information, allowing for device identification and pairing through a centralized management unit, which includes receiving purchasing information and device details to pre-configure new devices for seamless connection with existing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If QR code scanning is used for device pairing, then device identification is improved, but device complexity increases due to requiring camera and Internet connectivity
Solution Approach 1:
The patent introduces a server as an intermediary that stores device information and facilitates pairing. Instead of requiring direct camera-based QR scanning between devices, the server mediates the pairing process by providing device information to the terminal, enabling pairing for devices without cameras or Internet connectivity.
Solution Approach 2:
The patent segments the pairing process into two parts: device information management (handled by the server) and actual pairing (handled by the terminal). This segmentation allows devices without Internet connectivity or cameras to be paired, as the server handles the information provision while the terminal handles the connection.
2Adaptability or versatility
If additional hardware like NFC is added for device pairing, then pairing capability is improved, but device cost increases
Solution Approach 1:
The patent creates a universal pairing mechanism that works across different device types and communication protocols (Bluetooth, Wi-Fi, etc.) without requiring specialized hardware like NFC. The server-based approach provides multi-functional pairing capability using only existing short-range communication hardware.
Solution Approach 2:
The server acts as an intermediary that enables pairing without requiring additional hardware on the devices themselves. By providing device information through the server, the system achieves versatile pairing capability while avoiding the cost of adding NFC or other specialized hardware to each device.
3Reliability
If manual registration processes are used for device interworking, then connection reliability is improved, but operation complexity increases
Solution Approach 1:
The patent performs preliminary actions by having the server store device information in advance. When pairing is needed, the terminal simply retrieves this pre-stored information from the server, eliminating the need for manual registration processes while maintaining connection reliability.
Solution Approach 2:
The system enables self-service pairing where the terminal automatically obtains device information from the server and completes pairing without manual intervention. This eliminates complex manual registration processes while ensuring reliable connections through server-verified device information.
