Remote Smart Device Control via Server Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart device control systems are limited by distance, requiring the user and device to be within a local network, typically within 50 meters, for management and operation.
Innovation Solution
A device controlling method that allows users to log into a client to control connected devices from anywhere by using an intermediate device and server, enabling resource downloading and operation instructions to be sent through the server, eliminating the need for local network proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If local network management is used to control smart devices, then device control reliability is ensured within the local area, but the operation distance is limited to within 50 meters and the same wireless local area network is required
Solution Approach 1:
The patent introduces a server as an intermediary component that mediates between the user's terminal device and the smart device. The server receives control instructions from the user's terminal, forwards them to the smart device, and relays execution results back to the user. This intermediary architecture enables remote control without requiring the user and smart device to be in the same local network, thereby extending operation distance while maintaining control reliability.
2Adaptability or versatility
If a server-based remote control system is implemented, then operation distance is extended to anywhere in the world, but the system complexity increases with additional components
Solution Approach 1:
The patent designs the server to perform multiple functions: it acts as a message relay between user terminals and smart devices, stores device information and user credentials, manages device binding relationships, and handles control instruction routing. By consolidating these diverse functions into a single universal server platform, the system achieves global remote access capability while avoiding the complexity of multiple specialized components working together.

AI summary
A device controlling method, a client, a server and an intermediate device are provided. The device controlling method comprises acquiring information on an intermediate device and information on a controlled device associated with the intermediate device; sending a resource downloading command carrying the information on the intermediate device which is to obtain a resource to a server so as to enable the intermediate device to obtain the resource via the server; and sending an operation instruction to the controlled device associated with the intermediate device so as to enable the controlled device to obtain the resource from the intermediate device to perform an operation according to the operation instruction.
