Application State Transfer via Intermediary Approval Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face the challenge of continuing an application's session across different computing devices without losing operation history, as current applications store data locally, preventing undo and redo operations on different devices.
Innovation Solution
A method and system for transferring the state of an application from a first computing device to a second computing device, involving a request for approval, sending the application state, and acknowledging successful receipt, allowing the second device to restore the application's session and notify the first device to remove the state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If application data is stored locally on each computing device, then data storage is simple and fast, but the application session cannot be continued on different devices
Solution Approach 1:
The patent introduces a server as an intermediary component that receives application state data from the first computing device and transfers it to the second computing device. This mediator resolves the contradiction by enabling cross-device session continuity without requiring direct complex synchronization between devices, thus improving adaptability while managing device complexity through centralized server handling.
2Adaptability or versatility
If application state is transferred between devices, then session continuity is enabled, but security risks increase due to unauthorized access potential
Solution Approach 1:
The patent implements an approval mechanism where the second computing device must approve the transfer request before the application state is actually transferred. This feedback loop ensures that transfers only occur when authorized, resolving the contradiction by enabling session continuity while preventing unauthorized access through user-confirmed approval steps.
3Adaptability or versatility
If application data is stored in multiple locations across devices, then session continuity is improved, but data consistency and synchronization become more difficult
Solution Approach 1:
The server acts as a centralized intermediary that manages application state data, receiving it from the first device and providing it to the second device. This approach enables multi-device access while simplifying synchronization complexity, as the server maintains a single source of truth and handles all data transfer operations, eliminating the need for complex peer-to-peer synchronization protocols.
