Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing IoT systems require data transmission through external servers, leading to reduced message transmission speed, high costs for server maintenance, and increased risk of personal information leakage.
Innovation Solution
A standalone IoT gateway that uses local area communication technology to directly transmit data between IoT devices and user terminals, with a connection mode determination unit to switch between modes for efficient data processing and backup, and includes communication modules for various protocols and a Wi-Fi host unit for wireless Internet connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmission is performed through an external server, then data management and storage are centralized, but message transmission speed is reduced
Solution Approach 1:
The system segments data transmission paths into two modes: direct peer-to-peer transmission for real-time messages and server-based transmission for data management and backup. This allows message transmission to occur without server intervention while maintaining centralized data management capabilities.
Solution Approach 2:
The IoT gateway acts as an intermediary that can operate in two modes: as a direct communication bridge between IoT devices and user terminals, or as a server-connected interface for data management. This intermediary role enables flexible switching between speed-optimized and management-optimized transmission paths.
2Reliability
If an external server is constructed and maintained, then data storage and management capabilities are enhanced, but construction and maintenance costs increase
Solution Approach 1:
The system enables self-service operation where IoT devices and user terminals can directly exchange data without requiring external server infrastructure. The gateway provides local data storage and management capabilities, eliminating the need for expensive server construction and maintenance while maintaining data storage functionality.
Solution Approach 2:
The invention extracts the essential data storage and management functions from expensive external server infrastructure and implements them locally in the gateway using cost-effective components, thereby reducing system construction and maintenance costs while preserving data storage capability.
3Reliability
If data is transmitted through a company's server, then centralized management is achieved, but personal information leakage risk increases
Solution Approach 1:
The system segments sensitive personal information transmission from general data management functions. Direct peer-to-peer transmission channels are used for personal information exchange between IoT devices and user terminals, while server connection is optional and separated for non-sensitive data management tasks.
Solution Approach 2:
The gateway serves as a trusted local intermediary that manages data between IoT devices and user terminals without requiring external company servers. This local mediation eliminates the need to transmit personal information through company servers, reducing leakage risk while maintaining centralized management capabilities locally.
4Ease of manufacture
If a standalone gateway without server connection is used, then cost is reduced and information security is improved, but data backup capability is limited
Solution Approach 1:
The gateway implements dynamic operation modes that can switch between standalone mode (for cost-effective operation) and server-connected mode (for enhanced backup capability). This dynamic flexibility allows the system to maintain low costs while providing backup capability when needed, resolving the contradiction between cost reduction and backup capability.

AI summary
Provided is a standalone IoT gateway that can provide Internet of Things services without going through a server comprising a connection mode determination unit which determines one of a first connection mode and a second connection mode, a first service performing unit which transmits status messages obtained from one or more IoT devices to a smart device of a user through a router or receives control commands for the IoT devices from the smart device of the user through the router and transmits the received control commands to the IoT devices when the first connection mode is determined as a connection mode and a second service performing unit which transmits the status messages obtained from the IoT devices to a management server through the router or receives the control commands for the IoT devices from the management server through the router and transmits the received control commands to the IoT devices when the second connection mode is determined as the connection mode.
