Solution Overview

Problem

In existing wireless LAN environments, when the access point of a station device is changed, the connected devices must manually search and update their settings to connect to the new access point, which is inconvenient for users.

Innovation Solution

A method and device where a station device automatically transmits connection change information to a mobile device, including network details of the new access point, allowing the mobile device to seamlessly switch connections using UPnP or TCP/IP protocols, thereby eliminating the need for manual settings updates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the access point of a station device is changed, then the station device can connect to a new network, but the connected mobile devices cannot automatically follow and must manually update their settings

Engineering Contradiction:

Improvenetwork adaptabilityVSAvoidconnection management

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The station device monitors its own access point connection status and automatically feeds back this information to connected mobile devices. When the station device detects an access point change, it transmits the new access point information to mobile devices, enabling them to automatically update their connections without manual intervention.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The station device acts as an intermediary between the access point and mobile devices. It receives access point information, processes it, and relays it to mobile devices that need to connect. This intermediary role allows the station device to coordinate the connection changes and ensure smooth transitions for all devices in the network.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If manual settings updates are required for each mobile device when changing access points, then connection accuracy can be maintained, but user time and effort increase significantly

Engineering Contradiction:

Improveconnection reliabilityVSAvoidconfiguration time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The station device prepares and transmits access point information to mobile devices in advance, before the mobile devices need to reconnect. By proactively providing the new access point details, the system eliminates the need for mobile devices to manually search and configure connections, significantly reducing configuration time while maintaining connection reliability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Mobile devices automatically receive and process access point information from the station device, enabling self-service connection updates. The mobile devices don't require user intervention to search for, select, or configure new access points - they autonomously update their connections based on information provided by the station device.

Inventive Principle:

Principle #25Self-service

AI summary

A station device includes: a communication unit wirelessly communicating with a mobile device that forms a subnet with the station device; a user input unit that receives a user command input for terminating a connection with a first access point and connecting to a second access point; and a controller that controls the communication unit so as to transmit, to the mobile device, connection change information for changing a connection of the mobile device in response to the user command.
