Solution Overview

Problem

Users of proprietary SIM cards with VPN services must manually create VPN profiles and input credentials each time they connect, leading to unsatisfactory user experience.

Innovation Solution

A method and client that automatically connect to a VPN server by acquiring the SIM card's IP address and using preset information bases to retrieve and store VPN server addresses and login accounts, allowing for seamless and automatic network connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual VPN profile creation and credential input are required, then system security and control are maintained, but user experience and connection efficiency deteriorate

Engineering Contradiction:
Improveuser experienceVSAvoidmanual configuration requirement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-storing VPN server addresses and login credentials in information bases before actual connection is needed. When a user connects the SIM card, the system automatically retrieves and uses these pre-prepared credentials, eliminating the need for manual input during connection and significantly improving ease of operation.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If automatic connection is implemented using IP address matching, then connection efficiency is improved, but system complexity increases

Engineering Contradiction:
Improveconnection efficiencyVSAvoidautomatic connection mechanism
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements self-service by enabling the system to automatically determine which VPN server to connect to based on the SIM card's IP address. The system autonomously queries the IP address, matches it against stored address segments in the information base, retrieves corresponding credentials, and establishes the connection without user intervention, thereby improving productivity while managing complexity through automated workflows.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent uses feedback mechanisms by continuously monitoring the SIM card's IP address assignment and automatically adjusting the VPN connection based on this information. The system queries the current IP address, compares it with stored segments, and dynamically selects the appropriate VPN server, creating a closed-loop control system that improves connection efficiency.

Inventive Principle:
Principle #23Feedback

3Loss of time

If IP address-based automatic server selection is used, then manual input is reduced, but information storage and retrieval complexity increases

Engineering Contradiction:
Improvetime for credential inputVSAvoidinformation base structure
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-organizing VPN server addresses and login credentials into structured information bases before they are needed. The system pre-stores address segments and their corresponding credentials, so when connection is required, the matching and retrieval process is already optimized, reducing the time loss for credential input while managing information storage complexity through advance preparation.

Inventive Principle:
Principle #10Preliminary action
