Bluetooth Device Discovery Using Auditory Alarms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Bluetooth link establishment procedures are inefficient, leading to unnecessary device discovery time and power consumption, and users face difficulties in identifying the correct device among multiple devices with the same model name, potentially resulting in incorrect pairings.
Innovation Solution
A Bluetooth connection establishment method and system that utilizes visual, auditory, and tactile alarms to indicate receipt of inquiry and alarm trigger signals, allowing users to accurately identify and select target devices, thereby reducing discovery time and conserving power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the device discovery process continues until a predetermined discovery time expires, then all Bluetooth devices within range are discovered, but unnecessary waste of time and power occurs and battery life is reduced
Solution Approach 1:
The patent implements a feedback mechanism where the master device monitors for inquiry response signals from slave devices during the discovery process. When a response is detected, the system receives feedback that a target device has been located, allowing the discovery process to terminate early rather than continuing until the predetermined time expires. This resolves the contradiction by enabling timely termination while maintaining discovery completeness.
2Measurement precision
If the device discovery process continues until a predetermined discovery time expires, then all Bluetooth devices within range are discovered, but power consumption increases and battery life is reduced
Solution Approach 1:
The system uses feedback from inquiry response signals to determine when device discovery is complete. When the master device receives a response from a slave device, it terminates the discovery process early, avoiding continued power consumption. This resolves the contradiction between maintaining complete device discovery and reducing power usage by enabling timely termination based on actual discovery status.
3Quantity of substance
If multiple devices with the same model names are displayed in the slave device list, then device availability is shown, but user identification of the desired target device becomes difficult and incorrect selection may occur
Solution Approach 1:
The patent applies local quality by providing distinctive identification characteristics to each slave device in the list. Instead of all devices having the same model name display, each device is given unique identifying information such as device addresses or individualized identifiers. This allows users to easily distinguish between multiple devices with identical model names, resolving the contradiction between showing all available devices and making them easy to identify.

AI summary
A Bluetooth connection establishment method and system is provided for facilitating establishment of a communication channel between a master device and a target slave device. The method has the steps of broadcasting an inquiry signal for discovering a slave device and transmitting an inquiry response signal. The inquiry response signal is communicated from the slave device to a master device and the inquiry response signal indicates that the inquiry signal has been received by the slave device. The method requests at the master device that the at least one slave device transmits identification information. A slave device list is displayed. An alarm is transmitted by the at least one slave device that received the inquiry signal and a second alarm is transmitted by a target slave device selected from the slave device list in response to an alarm trigger signal transmitted by the master device.
