Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Bluetooth pairing for mobile terminals often requires user input of a passkey or PIN, leading to delays and increased power consumption, especially when switching between headsets, and can result in undesired connections with other devices.

Innovation Solution

An automatic pairing method that simplifies the Bluetooth pairing process by using preset buttons to initiate pairing between a mobile terminal and a headset, reducing power consumption and preventing undesired connections, by checking for and sending automatic authentication information to establish a Bluetooth connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual PIN input is required for Bluetooth pairing, then connection security is improved, but pairing time and user operation complexity increase

Engineering Contradiction:

Improveconnection securityVSAvoidpairing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-configuring authentication information in the headset before pairing. The headset stores authentication data in advance, so when pairing is initiated, the mobile terminal can automatically retrieve and use this pre-prepared information without requiring manual user input, thus reducing pairing time while maintaining security

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements self-service by enabling the mobile terminal to automatically obtain and process authentication information from the headset without user intervention. The system performs the pairing authentication process autonomously, where the terminal automatically receives, stores, and uses the authentication data to establish the connection

Inventive Principle:

Principle #25Self-service

2Measurement precision

If manual PIN input is required for Bluetooth pairing, then connection accuracy is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveconnection accuracyVSAvoidpairing operation

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The system performs pairing authentication autonomously by automatically receiving and processing authentication information from the headset. The mobile terminal independently completes the entire pairing process without requiring user input, making the operation simple while ensuring accurate connection to the intended device

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent uses feedback mechanisms where the mobile terminal receives authentication information from the headset and automatically processes it. The system monitors the pairing process and confirms successful connection, providing feedback that ensures accurate pairing without requiring manual verification by the user

Inventive Principle:

Principle #23Feedback

3Reliability

If headset performs inquiry procedure to find mobile terminal, then connection reliability is improved, but power consumption increases

Engineering Contradiction:

Improveconnection reliabilityVSAvoidheadset power consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies preliminary action by having the mobile terminal proactively send authentication information to the headset before the headset needs to perform an inquiry. This reverse approach allows the headset to receive connection information in advance, eliminating the need for power-consuming inquiry procedures while ensuring reliable connection

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent inverts the traditional Bluetooth pairing approach where the slave device (headset) performs inquiry to find the master device (terminal). Instead, the master device sends authentication information to the slave device, reversing the initiation direction and allowing the headset to remain in a lower power state without performing energy-intensive scanning

Inventive Principle:

Principle #13The other way round (Inversion)

4Ease of operation

If automatic pairing is implemented, then ease of operation and power consumption are improved, but connection security may deteriorate

Engineering Contradiction:

Improvepairing operationVSAvoidconnection security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent implements feedback by having the mobile terminal automatically receive and verify authentication information from the headset. The terminal processes the authentication data and confirms successful pairing, ensuring that automatic connection maintains security through automated verification procedures

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs secure authentication autonomously through self-service mechanisms. The mobile terminal automatically manages the authentication process, retrieving and verifying credentials without user intervention, thereby maintaining connection security while enabling easy automatic pairing

Inventive Principle:

Principle #25Self-service

AI summary

An automatic pairing method for a Bluetooth®-enabled mobile includes checking whether automatic authentication information has been received from a Bluetooth®-enabled appliance in response to an automatic pairing command, receiving pairing information from the Bluetooth®-enabled appliance and registering the Bluetooth®-enabled appliance as a slave if automatic authentication information is received, and establishing a Bluetooth® connection to the Bluetooth®-enabled appliance registered as a slave.
