Solution Overview

Problem

Current wireless networks fail to automatically switch to better connections, leading to poor signal quality and connectivity issues, especially with smart devices, due to the need for manual authentication and incompatibility between different wireless devices.

Innovation Solution

A wireless network communication system with a master controller and slave controllers that automatically manage connections by transmitting uplink signal strength information, allowing for dynamic threshold settings and automatic switching between base stations to optimize connection quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual authentication is required for each access point, then security is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveconnection securityVSAvoidautomatic connection
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary authentication by establishing master-slave relationships between access points before the user needs to connect. The master controller pre-authenticates slave controllers, so when a user device moves between access points, the authentication is already complete and connection can be automatically established without requiring manual authentication at each new access point.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces a master controller as an intermediary that manages authentication centrally. Instead of requiring direct authentication between each user device and access point, the master controller acts as a mediator that pre-establishes trust relationships, allowing seamless automatic reconnection while maintaining security through the centralized authentication framework.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the wireless device maintains connection with the original access point, then connection stability is improved, but signal quality deteriorates

Engineering Contradiction:
Improveconnection stabilityVSAvoidsignal quality
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The system implements feedback mechanisms where the master controller continuously monitors signal quality metrics from multiple slave controllers. When signal quality at the current access point deteriorates below a threshold, the system receives feedback about alternative access points with better signal strength and automatically initiates switching to maintain both connection stability and signal quality.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent makes the connection dynamic by enabling automatic switching between access points based on real-time signal conditions. Instead of statically maintaining connection to the original access point, the system dynamically evaluates signal quality and automatically transitions to optimal access points, ensuring both stability and quality are maintained throughout user movement.

Inventive Principle:
Principle #15Dynamics

3Area of stationary object

If coverage area is expanded with more access points, then coverage is improved, but device complexity increases

Engineering Contradiction:
Improvewireless coverageVSAvoidnetwork management
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent segments the wireless network into a hierarchical master-slave architecture where access points are divided into master controllers and slave controllers. This segmentation allows multiple access points to be managed independently with clear role definitions, simplifying the management of expanded networks by organizing numerous access points into structured groups rather than requiring centralized management of all devices equally.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The master controller serves multiple functions including authentication management, signal quality monitoring, and automatic switching coordination. This multi-functionality reduces device complexity by consolidating management tasks into a single universal controller that can handle multiple slave controllers, eliminating the need for separate management systems for each access point in the expanded network.

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

AI summary

A wireless network communication system and its communication method of the present invention is mainly initiated from an interconnected state between a master controller, at least one slave controller and at least one working station (STA). The at least one slave controller is capable of transmitting an uplink signal strength (rssiVal) with the at least one working station (STA) to the master controller so that the master controller can instruct commands of disconnection or connection to the at least one slave controller according to the uplink signal strength (rssiVal) with the at least one working station (STA) transmitted from the at least one slave controller, and the at least one slave controller can automatically disconnecting from or connecting with the at least one working station (STA) so as to achieve automatic switch between base stations (wireless Internet devices) and obtain the best and most stable connection quality.
