Client Device Automatic Reconnection via Backup SSID Storage

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users face significant time and financial burdens when manually reconnecting multiple client devices to a Wi-Fi network after a change in the network's service set identifier (SSID) or passphrase, as existing methods require manual intervention for each device.

Innovation Solution

A method and system that automatically updates client device access by establishing a first wireless connection with a primary SSID/passphrase, storing a backup SSID/passphrase, and then switching to the backup SSID/passphrase when the primary connection is lost, allowing the client device to reconnect to the electronic device with the new SSID/passphrase.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual reconnection method is used for each client device after SSID/passphrase change, then network security is improved through password change, but user time and operational cost increase significantly

Engineering Contradiction:

Improvenetwork securityVSAvoidreconnection time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by storing backup SSID/passphrase pairs before the primary credentials are changed. When disconnection occurs, the client device automatically retrieves and uses the pre-stored backup credentials to reconnect, eliminating the need for manual reconfiguration after security changes.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The client device is enabled to automatically detect connection loss, retrieve backup credentials from local storage, and initiate reconnection without user intervention. This self-service mechanism resolves the contradiction by maintaining security (through controlled credential changes) while eliminating manual reconnection time.

Inventive Principle:

Principle #25Self-service

2Reliability

If manual reconnection is required for each client device, then network authentication control is maintained, but operational cost and complexity increase

Engineering Contradiction:

Improveauthentication controlVSAvoidreconnection operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system implements self-service by enabling client devices to automatically manage their own reconnection process using stored backup credentials. This maintains authentication control through the electronic device's ability to validate credentials while dramatically simplifying the user operation from manual intervention to automatic transparent reconnection.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Backup credential pairs are preliminarily stored in the client device before disconnection occurs. This preliminary preparation enables the device to autonomously handle reconnection, reducing operational complexity while maintaining security through controlled credential distribution from the electronic device.

Inventive Principle:

Principle #10Preliminary action

3Speed

If backup SSID/passphrase is stored and automatically used for reconnection, then reconnection speed is improved, but system complexity increases

Engineering Contradiction:

Improvereconnection speedVSAvoidconnection management complexity

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The system stores multiple SSID/passphrase credential pairs in advance in the client device's database. When connection is lost, the device automatically retrieves the next available backup credential without requiring complex real-time decision-making, achieving fast reconnection with minimal added complexity through pre-computed credential sequences.

Inventive Principle:

Principle #10Preliminary action

AI summary

A system, method, and computer-readable recording media. Initially establishing a first wireless communication connection between a client device (CD) and an electronic device (ED) with a first primary SSID/passphrase. Storing a backup SSID/passphrase in the ED. Sending a message from the ED to the CD, the message including the backup SSID/passphrase. Storing the backup SSID/passphrase in the CD. Replacing the first primary SSID/passphrase on the ED with a second primary SSID/passphrase. After the first wireless communication connection between the CD and the ED is lost, retrieving, within the CD, the backup SSID/passphrase, and establishing a second wireless communication connection between the CD and the ED. After second wireless communication connection is established, sending a message including second primary SSID/passphrase from the ED to the CD. Storing second primary SSID/passphrase in the CD. Establishing a third wireless communication connection between the CD and the ED with the second primary SSID/passphrase.
