Solution Overview

Problem

Users face inconvenience and reduced utilization efficiency due to the manual switching operations required for establishing a connection with a Wireless Local Area Network (WLAN) through an Access Point (AP), leading to inefficient power usage.

Innovation Solution

A method and device for wireless control that utilizes a Blue Tooth (BT) module to detect terminals and dynamically turn on/off the WLAN module of the AP, allowing intelligent control of both BT and WLAN modules to conserve energy by only activating them when necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the WLAN module is manually switched on by the user, then the connection establishment is possible, but the operation convenience deteriorates and power consumption increases

Engineering Contradiction:

Improveconnection establishment convenienceVSAvoidpower consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The AP automatically detects terminal connections through the BT module and autonomously activates the WLAN module without requiring manual user intervention, enabling the system to serve itself and eliminate the need for user-operated switching

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The BT module performs preliminary detection of terminal connections before the WLAN module is activated, allowing the system to prepare and trigger the WLAN activation in advance based on detected connection needs

Inventive Principle:

Principle #10Preliminary action

2Speed

If the WLAN module is always on, then the connection establishment is fast, but the power consumption increases

Engineering Contradiction:

Improveconnection establishment speedVSAvoidpower consumption

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the power state of the WLAN module based on real-time detection of terminal connections, transitioning between active and inactive states as needed rather than maintaining a static always-on or always-off configuration

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The AP uses feedback from the BT module's terminal detection results to control the WLAN module's activation state, creating a closed-loop system that responds to actual connection needs

Inventive Principle:

Principle #23Feedback

3Use of energy by moving object

If the manual switching operation is required, then the power saving is possible, but the operation convenience deteriorates

Engineering Contradiction:

Improvepower savingVSAvoidconnection establishment convenience

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The system performs automatic detection and activation without requiring user intervention, eliminating the manual switching operation while maintaining power saving benefits through intelligent automation

Inventive Principle:

Principle #25Self-service

AI summary

Provided are a method and device for wireless control. The method includes that: detection is performed through a Bluetooth (BT) module of an Access Point (AP) to determine whether a terminal is detected or not; and responsive to that the terminal is detected and that a Wireless Local Area Network (WLAN) module of the AP is off, the WLAN module of the AP is turned on. According to the embodiments of the present disclosure, the WLAN module of the AP may be dynamically and automatically turned on, and a user is not required to check and turn on the WLAN module of the AP personally, so that the utilization efficiency is improved.
