Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IoT gateways face limitations in installation environments, require additional input or display devices for wireless connection to routers, struggle with accurately displaying Korean SSIDs, and are restricted to single communication protocols, making it difficult to connect a wide range of IoT devices effectively.
Innovation Solution
An IoT gateway with a WAN port monitoring module, operating mode determiner, smart device access module, and service provider that allows for wireless access to routers without additional input or display devices, accurately displays Korean SSIDs, and supports multiple communication protocols by rearranging router lists by signal strength and converting notation formats, enabling connection to various IoT devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gateway is directly connected to a router in a wired manner, then the connection is stable, but the installation environment is limited and the gateway cannot be placed flexibly in various spaces
Solution Approach 1:
The gateway is equipped with both wired Ethernet ports and wireless WiFi communication capabilities, allowing it to dynamically switch between connection modes. The gateway can adapt its connection method based on the installation environment, providing both stability when wired connection is available and flexibility when wireless connection is needed.
2Adaptability or versatility
If a gateway connects to a router wirelessly via WiFi, then the installation flexibility is improved, but additional input devices or display devices are required, increasing size and manufacturing cost
Solution Approach 1:
The gateway automatically performs WiFi connection procedures by autonomously scanning for available routers, selecting target routers based on signal strength, and completing authentication without requiring external input devices or display devices. This self-service capability eliminates the need for additional hardware components that would increase size and cost.
Solution Approach 2:
The patent replaces physical input devices (buttons, keyboards) and display devices with software-based interfaces and automated algorithms. The gateway uses electronic scanning and digital signal processing to identify and connect to routers, substituting mechanical interaction with electronic automation.
3Loss of information
If an existing gateway attempts to access a router with a Korean SSID, then the gateway should display the SSID accurately, but the gateway may not accurately display the Korean SSID, making it difficult to identify the router
Solution Approach 1:
The gateway provides real-time feedback by displaying the scanned router SSIDs in their accurate original form, allowing users to identify and select the target router. The system continuously monitors and updates the list of available routers, providing immediate visual feedback about connection options.
4Ease of operation
If an existing gateway arranges routers in alphabetical order of SSID, then the router list is organized, but it is difficult to select a router with high signal strength
Solution Approach 1:
The gateway changes the sorting parameter from alphabetical order of SSID to signal strength order. By prioritizing routers with stronger signal strengths in the displayed list, the system enables users to quickly identify and select the optimal router for connection, improving both ease of operation and connection efficiency.
5Device complexity
If an existing gateway supports only a single communication protocol, then the device complexity is reduced, but it is difficult to connect to IoT devices that use various communication protocols
Solution Approach 1:
The gateway is designed with multi-protocol support, incorporating multiple communication modules that can handle different IoT communication protocols simultaneously. This universal design allows the gateway to function as a bridge between various IoT devices using different protocols and the network, expanding compatibility without significantly increasing complexity.
Data Source
AI summary
Provided is an Internet of things (IoT) gateway to which it is possible to input access information for accessing a router without an additional input device and display device. The IoT gateway includes a wide area network (WAN) port monitoring portion; an operating mode determiner configured to determine an operating mode; a smart device access portion; a router access portion; and a service provider configured to, when the router access portion accesses the target router, transfer status messages acquired from one or more IoT devices to the target router, or receive control commands for the one or more IoT devices from the target router and transfer the control commands to the corresponding IoT devices.
