Solution Overview

Problem

Wireless communication devices face challenges in establishing appropriate connections with multiple devices, particularly in scenarios where signal strength is poor or intermittent, and in managing simultaneous Wi-Fi Direct (WFD) and non-WFD connections.

Innovation Solution

The wireless communication device determines the value of the first wireless channel to be identical to the second wireless channel, allowing it to operate in a parent station state and establish both WFD and non-WFD connections effectively by referencing setting values and channel priorities, ensuring stable communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the wireless communication device establishes separate channels for WFD and non-WFD connections, then connection versatility is improved, but channel stability deteriorates due to potential interference and signal strength issues

Engineering Contradiction:
Improveconnection versatilityVSAvoidchannel stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent merges the WFD connection and non-WFD connection into a single shared wireless channel. The determination unit identifies when both connection types are active and instructs the connection unit to use the same channel for both, eliminating channel interference and improving stability while maintaining the ability to support both connection types simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The wireless communication device is designed to handle multiple connection types (WFD and non-WFD) on a single channel through intelligent management. The determination unit and connection unit work together to make the same channel serve dual purposes, allowing the device to be universally compatible with different connection protocols without requiring separate dedicated channels for each.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If the device prioritizes non-WFD connections for stability, then channel reliability is improved, but WFD connection establishment speed deteriorates

Engineering Contradiction:
Improvechannel reliabilityVSAvoidconnection establishment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The determination unit proactively identifies when both WFD and non-WFD connections are active before connection issues arise. By提前 determining the need to use the same channel and instructing the connection unit accordingly, the system prevents connection instability rather than reacting to it, ensuring both connection types can coexist without interference and establishing WFD connections efficiently.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the device uses channel switching processing to manage multiple connections, then connection adaptability is improved, but device complexity increases

Engineering Contradiction:
Improveconnection adaptabilityVSAvoidchannel switching complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the complex channel switching processing mechanism. Instead of implementing multiple channel management protocols and switching logic, the system simplifies to using a single shared channel for both WFD and non-WFD connections, managed by the determination unit and connection unit. This removes the complexity of channel switching while maintaining adaptability through intelligent connection management.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A wireless communication device (10) may establish a first type of connection by using a first wireless channel. The wireless communication device (10) may establish the second type of connection by using a second wireless channel. In a specific case where one of the first type of connection with the first device (8) and the second type of connection with the second device (4) is to be established under a situation in which the other has been established, the wireless communication device (10) may determine at least one of a value of the first wireless channel and a value of the second wireless channel such that the value of the first wireless channel is identical to the value of the second wireless channel.
