Solution Overview

Problem

Users face productivity losses due to disjointed experiences across different device types, as separate login and authentication procedures exist for web and mobile platforms, lacking seamless connectivity between them.

Innovation Solution

A method and system that utilize a dynamic QR code to establish a connection across systems, allowing users to bind multiple devices to a session state, enabling seamless authentication and maintaining session continuity across devices by creating a unique QR code that preserves user activity and account changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate login and authentication procedures are implemented for different device types (web and mobile platforms), then each platform can be securely accessed independently, but users experience productivity losses due to disjointed experiences and cannot seamlessly connect between platforms

Engineering Contradiction:

ImprovesecurityVSAvoiduser productivity

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent implements a universal authentication system where a single login credential set can authenticate users across multiple device types and platforms (web, mobile, tablet). The system creates a unified session state that works universally across different access routes, eliminating the need for separate login procedures for each platform while maintaining security through centralized authentication management.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges previously separate authentication systems for different platforms into a single unified authentication mechanism. By combining web and mobile authentication into one system that shares session states, the patent enables seamless transitions between platforms while maintaining security, thus resolving the contradiction between security and user productivity.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If each access route operates in isolation with its own login features, then platform independence is maintained, but seamless connectivity between platforms is lost

Engineering Contradiction:

Improveplatform independenceVSAvoidseamless connectivity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces session states as an intermediary mechanism that connects different access routes (web, mobile, tablet). These session states act as mediators that carry authentication information across platforms, enabling seamless connectivity while preserving platform independence. Each platform can operate independently yet remain connected through the shared session state infrastructure.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If users must re-enter login credentials for each device, then security is maintained through repeated authentication, but user experience deteriorates and productivity decreases

Engineering Contradiction:

Improveauthentication securityVSAvoiduser experience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent performs preliminary authentication once when the user logs in to any device. This initial authentication action creates a session state that is then reused across multiple devices and platforms, eliminating the need for repeated authentication. The preliminary authentication maintains security while significantly improving ease of operation and user experience.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent creates copies of the authentication session state and distributes them across multiple devices. Instead of requiring users to re-enter credentials on each device, the system copies the validated session information to multiple platforms, maintaining security through centralized session management while greatly improving ease of operation and user experience.

Inventive Principle:

Principle #26Copying

4Adaptability or versatility

If multiple devices are supported with separate authentication systems, then device compatibility is achieved, but session state preservation across devices becomes impossible

Engineering Contradiction:

Improvedevice compatibilityVSAvoidsession state preservation

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent creates a universal session state infrastructure that functions across multiple device types (mobile phones, tablet computers, desktop and laptop computers). This universal session management system preserves user activity and account changes across all devices, eliminating session state loss while maintaining broad device compatibility through a unified approach.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Establishing a dynamic connection across systems is provided. The method comprises receiving user login credentials from a user from a first device and authenticating the user login credentials in connection with a user account. A session is created in response to successful authorization of the user login credentials, wherein the session comprises a session state that tracks user activity and any changes to a user account during the session, and the first device is bound to the session state and saved as a known device. Upon detecting activity of the user on a second device, a quick response code is created for the user. When the user inputs the quick response code from the second device, the second device is bound to the session state and logged into the session with the session state preserved.
