Solution Overview

Problem

The existing wireless headset reconnection process is user-dependent and delayed, requiring active triggering through a headset box or button, which affects user experience due to the need for manual intervention and timeouts.

Innovation Solution

A method and device that detect the motion state of the wireless headset, determine its working mode, and automatically send a connection request to the terminal if not connected, utilizing sensors like accelerometers and infrared sensors to determine if the headset is being worn and in a disconnection state, thereby initiating automatic reconnection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a timeout mechanism is used for automatic reconnection, then battery life is improved and power consumption is reduced, but user experience deteriorates due to manual intervention requirements and connection delays

Engineering Contradiction:

Improvepower consumptionVSAvoiduser experience

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The wireless headset automatically detects its own wearing state through sensors (accelerometer, infrared sensor) and autonomously initiates reconnection procedures without requiring user intervention. The system monitors connection status, determines wearing state, and sends reconnection requests automatically, enabling the device to serve itself in the reconnection process.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary detection of wearing state using sensors before initiating reconnection. By detecting motion state, infrared blockage, and acceleration values in advance, the system prepares to reconnect proactively when the headset is detected to be worn, rather than waiting for timeout or user action.

Inventive Principle:

Principle #10Preliminary action

2Device complexity

If manual triggering through headset box or button is required for reconnection, then device complexity is reduced, but loss of time increases due to delay from wearing to usability

Engineering Contradiction:

Improvereconnection mechanismVSAvoidconnection delay

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The patent replaces mechanical triggering mechanisms (physical buttons on headset or headset box) with sensor-based detection systems. Accelerometers, infrared sensors, and motion detection algorithms automatically determine wearing state and trigger reconnection, substituting mechanical user interaction with automated sensing and processing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system continuously monitors connection status and wearing state through sensors, creating a feedback loop that automatically triggers reconnection when the headset is detected to be worn and disconnected. The system adjusts its behavior based on real-time sensor data, creating an adaptive reconnection mechanism.

Inventive Principle:

Principle #23Feedback
