Solution Overview

Problem

Interference between WiMAX and Bluetooth frequency bands in electronic devices due to their proximity in frequency, leading to performance degradation when both technologies are used simultaneously.

Innovation Solution

A control method and electronic device configuration that determines the priority between the Bluetooth and WiMAX modules, setting the Bluetooth module to an inactive mode when WiMAX data needs protection and its priority is lower, to mitigate interference and ensure reliable operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If both WiMAX and Bluetooth modules operate simultaneously in the same electronic device, then the device can provide multiple wireless communication functions, but frequency interference occurs between the two modules due to their proximity in frequency bands

Engineering Contradiction:

Improvewireless communication functionalityVSAvoidfrequency interference

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements a dynamic priority mechanism that allows the Bluetooth module to switch between active and inactive states based on real-time WiMAX data transmission status. When WiMAX data needs protection, the Bluetooth module dynamically transitions to inactive mode, avoiding frequency interference. When WiMAX data does not need protection, the Bluetooth module activates to provide communication functionality.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameter of the Bluetooth module by setting its priority level relative to WiMAX module. Through priority determination and active/inactive state transitions, the system adjusts the Bluetooth module's operating parameters dynamically to prevent frequency interference while maintaining communication capabilities when appropriate.

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If the Bluetooth module is set to inactive mode to avoid interference with WiMAX data, then frequency interference is reduced, but Bluetooth communication functionality is lost during inactive periods

Engineering Contradiction:

Improvefrequency interferenceVSAvoidBluetooth communication availability

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The Bluetooth module's operational state is made dynamic rather than static. It transitions between active and inactive modes based on real-time conditions (WiMAX data protection needs), allowing the system to adaptively balance interference avoidance with communication availability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system periodically evaluates the priority relationship between Bluetooth and WiMAX modules and the data protection status, causing the Bluetooth module to switch between active and inactive states in periodic cycles based on changing communication needs and interference conditions.

Inventive Principle:

Principle #19Periodic action

AI summary

An embodiment of the disclosure provides a control method between a Bluetooth module and a wireless LAN module, for an electronic device with a Bluetooth module and a WiMAX module. The method comprises: determining whether the priority of the Bluetooth module is higher than that of the WiMAX module; determining whether data transmitted or received by the WiMAX module has to be protected; and when the priority of the Bluetooth module is not higher than that the WiMAX module and the data transmitted or received by the WiMAX module has to be protected, setting the Bluetooth module to be in an inactive mode.
