Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users face inconvenience when switching between devices, as they often need to re-enter data and selections, and existing technologies do not efficiently allow seamless session transfer across different devices without requiring re-login or losing context.

Innovation Solution

A system that detects and transfers portal sessions between devices using near field communication (NFC) or other mechanisms, allowing users to initiate a new session on another device while preserving the context of the original session, including user inputs, selections, and settings, without requiring re-authentication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If portal sessions are transferred between devices using existing technologies, then device compatibility is improved, but user authentication time increases due to required re-login

Engineering Contradiction:

Improvedevice compatibilityVSAvoidauthentication time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary authentication when the user initially logs in to the portal on the first device. The authentication credentials and session context are then cached and made available for rapid transfer to subsequent devices, eliminating the need for re-authentication on each device transition.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates a copy of the authenticated session context and transfers it to the second device. This copied session information includes user credentials and portal state, allowing the user to continue their portal experience without重新 authentication on the new device.

Inventive Principle:

Principle #26Copying

2Ease of operation

If portal sessions are transferred between devices, then user convenience is improved, but session context loss occurs without proper transfer mechanisms

Engineering Contradiction:

Improveuser convenienceVSAvoidsession context

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The system introduces a session context intermediary layer that captures, stores, and transfers the complete portal session state between devices. This intermediary mechanism ensures that all session information including user inputs, selections, and portal state is preserved during device transitions.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system maintains continuous session context across device boundaries by seamlessly transferring the portal session state from the first device to the second device. This continuity allows users to pick up their portal activities exactly where they left off on the new device without interruption or information loss.

Inventive Principle:

Principle #20Continuity of useful action

3Productivity

If session information is transferred between devices, then productivity is improved, but system complexity increases

Engineering Contradiction:

Improvesession transfer efficiencyVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system implements a universal session transfer mechanism that works across multiple device types and platforms. The session context transfer protocol is designed to be device-agnostic, allowing the same authentication and session management infrastructure to serve diverse devices including smartphones, tablets, laptops, and desktops.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system extracts the essential session context elements from the complex portal system and transfers only the necessary authentication credentials and session state data between devices. This extraction approach minimizes the amount of data transferred and reduces system complexity while maintaining productivity benefits.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A computer-implemented method includes: detecting, in a system running a portal, that a first portal session for a first user exists with regard to a first device operated by the first user; receiving a session transfer command that the first user generates using the first device and that indicates at least a second device; in response to the session transfer command, providing session information to the second device that reflects the first portal session; receiving a session initiation command that a second user generates using the second device, the session initiation command generated by the second device based on at least part of the session information; and in response to the session initiation command, creating a second portal session in the system, the second portal session corresponding to the first portal session.
