Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Bluetooth pairing procedures are time-consuming and require users to have a comprehensive understanding of the user interface, causing inconvenience, especially for elderly individuals, those with poor sight, or those with difficulty in finger manipulations.
Innovation Solution
A Bluetooth communication system comprising a transmitting-end device with a transceiver circuit, packet generating circuit, and control circuit that initiates an auto-pairing request and source address in packets, and a receiving-end device with a transceiver circuit, packet parsing circuit, and control circuit that automatically parses and responds to establish Bluetooth bonds without user intervention.

Engineering Contradiction Analysis
1Ease of operation
If conventional Bluetooth pairing procedure is used, then Bluetooth bond can be established, but user manipulation steps are numerous and time-consuming
Solution Approach 1:
The transmitting-end Bluetooth device automatically initiates the pairing procedure by sending packets containing auto-pairing requests and source addresses without requiring user intervention. The system serves itself by autonomously completing the pairing process, eliminating the need for users to manually scan, select, and confirm device connections.
Solution Approach 2:
The transmitting-end device pre-prepares packets with auto-pairing requests and source Bluetooth device addresses before the actual pairing occurs. This preliminary preparation enables the receiving-end device to automatically recognize and respond to the pairing request, streamlining the entire pairing process into a single automated interaction.
2Ease of operation
If conventional Bluetooth pairing procedure is used, then device connection can be established, but user interface understanding is required
Solution Approach 1:
The patent extracts the complex user interface interaction steps from the pairing process and replaces them with automated packet-based communication. The transmitting-end device sends structured packets containing auto-pairing requests and source addresses, eliminating the need for users to navigate touch screens, scan device lists, or understand interface commands.
3Extent of automation
If auto-pairing procedure is implemented, then user manipulation is reduced, but data transmission security must be maintained
Solution Approach 1:
The pairing data is segmented into structured packets that contain specific fields such as auto-pairing requests and source Bluetooth device addresses. This segmentation allows for controlled, verified data exchange between devices, maintaining security through structured communication while enabling full automation of the pairing process.

AI summary
A transmitting-end Bluetooth device includes: a transmitting-end Bluetooth transceiver circuit; a packet generating circuit, coupled with the transmitting-end Bluetooth transceiver circuit; and a transmitting-end control circuit, coupled with the transmitting-end Bluetooth transceiver circuit and the packet generating circuit, arranged to operably instruct the packet generating circuit to insert an auto-pairing request and a source Bluetooth device address into one or more target packets when the transmitting-end Bluetooth device initiates a Bluetooth auto-pairing procedure, and arranged to operably control the transmitting-end Bluetooth transceiver circuit to transmit the one or more target packets when the transmitting-end Bluetooth device operates under a predetermined transmitting-end operating mode, so that a receiving-end Bluetooth device operating under a predetermined receiving-end operating mode is enabled to actively conduct a Bluetooth auto-pairing procedure with the transmitting-end Bluetooth device to establish one or more Bluetooth bonds between the transmitting-end Bluetooth device and the receiving-end Bluetooth device.
