Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Bluetooth devices face challenges with high costs, operation inconvenience, and poor user experience due to limited transmission range and high power consumption, making it difficult to manage and control multiple devices located at different places.
Innovation Solution
A Bluetooth device networking system that includes a terminal and multiple Bluetooth devices, each with identification information, where the terminal initializes and controls devices within a preset range by broadcasting control commands, allowing one terminal to manage multiple devices through Bluetooth modules, authentication, and communication units, reducing the need for routing distribution and path calculation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth connection is used to control devices, then wireless control convenience is improved, but transmission range is limited and cannot effectively manage multiple devices located in different places
Solution Approach 1:
The patent introduces a gateway device as an intermediary to extend Bluetooth transmission range. The gateway receives control commands from the terminal via Bluetooth and forwards them to remote Bluetooth devices through other communication means, enabling indirect control of devices beyond direct Bluetooth range while maintaining wireless convenience
Solution Approach 2:
The system segments the control process into multiple stages: terminal to gateway via Bluetooth, then gateway to remote devices via other protocols. This segmentation allows each component to operate within its optimal range and capability, solving the limited transmission range problem while preserving ease of operation
2Length of stationary object
If WiFi or 2.4G wireless remote control is used to extend transmission range, then control range is improved, but power consumption increases and costs increase
Solution Approach 1:
The patent applies different communication protocols to different parts of the system based on local requirements: Bluetooth is used for short-range terminal-to-gateway communication (low power), while other protocols are used only for gateway-to-remote-device communication when extended range is needed. This localized approach ensures power consumption is minimized while achieving extended control range when necessary
3Adaptability or versatility
If ZigBee technology is used for networking control, then networking capability is improved, but use costs increase and conversion devices are required
Solution Approach 1:
The gateway device is designed with multi-functionality, supporting multiple communication protocols including Bluetooth, WiFi, and other wireless protocols. This universal gateway can adapt to different Bluetooth devices without requiring protocol-specific conversion devices, reducing overall system cost while maintaining strong networking capability
4Device complexity
If one terminal controls only one or two Bluetooth products, then Bluetooth connection simplicity is maintained, but device management capability is limited
Solution Approach 1:
The gateway acts as a mediator that manages multiple Bluetooth device connections. The terminal maintains simple one-to-one Bluetooth connection to the gateway, while the gateway handles multiple device connections and routing, thus preserving connection simplicity for the user while enabling management of multiple devices

AI summary
In the disclosure, a Bluetooth device networking method and system comprises the following steps: the terminal initialization preset all Bluetooth devices within the region, and record all Bluetooth devices corresponding to the identification information of the preset range. When the terminal needs to control the Bluetooth device in the preset area, only the control command information is broadcasted. The Bluetooth device receives the control command information equipment, judgment unit of the Bluetooth device will determine whether the identification information control command information contained in equipment for self-identification information corresponding, if executing the equipment control command information, otherwise it will continue to broadcast the control command information. When Bluetooth device executes the control command information, it broadcasts the response information to the outside, and is finally received by the terminal after being transmitted by Bluetooth network. Accordingly, the cost of networking the Bluetooth products of the outdoor can be effectively reduced.
