Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device control systems require dedicated applications for connection configuration, which complicates secure connections between controlled devices and wireless LAN routers, and may not function seamlessly across different operating systems and models.
Innovation Solution
A device control system that allows controlled devices to connect securely to a wireless LAN router without a dedicated application, using a handheld operation terminal and an external connector that switches between indoor and outdoor communication modes, utilizing Wi-Fi or Internet communication to manage device settings and operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated application is installed on the operation terminal for wireless connection configuration, then the controlled device can be connected to the wireless LAN router, but the system complexity increases and compatibility testing across different operating systems becomes necessary
Solution Approach 1:
The patent extracts the dedicated application requirement from the operation terminal by implementing connection configuration functionality directly in the controlled device. The controlled device now contains embedded wireless communication capabilities and configuration interfaces, eliminating the need for external dedicated applications on the operation terminal while maintaining reliable connection establishment.
Solution Approach 2:
The operation terminal is designed to perform multiple functions without requiring dedicated applications for each task. The terminal's existing web browser and interface capabilities are utilized to communicate with the controlled device's embedded configuration system, making the terminal universal for both connection setup and operational control across different operating systems.
2Speed
If wireless configuration software is installed on the operation terminal to establish direct communication, then connection speed improves, but the ease of operation decreases due to installation and compatibility testing requirements
Solution Approach 1:
The controlled device performs self-configuration for wireless connections by maintaining embedded configuration interfaces and handling its own connection setup processes. The device can be configured through its built-in interface accessible via the operation terminal's web browser, eliminating the need for the user to install and configure separate wireless configuration software on the operation terminal.
Solution Approach 2:
The controlled device comes pre-configured with embedded wireless communication capabilities and configuration interfaces during manufacturing. This preliminary preparation allows the device to be set up quickly through the operation terminal's existing browser functionality without requiring any additional software installation or compatibility testing beforehand.

AI summary
Provided is a device control system (100) for controlling a wireless device (200) provided indoors from an operation terminal (7) via a network (6). The wireless device (200) includes a router connection mode in which the wireless device (200) and the operation terminal (7) are connected via a wireless LAN router (3); a terminal connection mode in which the wireless device (200) and the operation terminal (7) are connected without the wireless LAN router (3); and a switch that switches the mode between the router connection mode and the terminal connection mode. The wireless device (200) searches for one or a plurality of the wireless LAN routers (3) located around the wireless device (200) after the switch is pressed for a predetermined period of time or longer with the router connection mode that is set; lists network information of the one or plurality of the wireless LAN routers (3) that are searched; and then switches the mode from the router connection mode to the terminal connection mode.
