Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current online Internet applications are difficult to continue in a portable context due to hardware and connectivity requirements, limiting users to stationary devices and preventing seamless continuation of experiences and progress between online and offline environments.
Innovation Solution
A method and system for synchronizing an online user account with a portable device, allowing data exchange and interaction while offline, using a client machine as an intermediary or directly with the online network, and utilizing metadata transfers to expedite data synchronization upon reconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If online applications are executed on portable devices, then user mobility and accessibility are improved, but processing power and hardware performance deteriorate
Solution Approach 1:
The patent introduces a server as an intermediary between the portable device and the online application. The server hosts the application and handles complex processing, while the portable device acts as a thin client providing only basic interface functionality. This resolves the contradiction by offloading processing power requirements from the portable device to the server, enabling user mobility without sacrificing application performance.
2Reliability
If online applications require constant internet connectivity, then data synchronization is improved, but user accessibility in offline environments deteriorates
Solution Approach 1:
The patent implements preliminary action by allowing the portable device to download and cache application data, user profiles, and configuration information before offline periods begin. The device stores this data locally and can execute the application offline using cached information. When connectivity is restored, synchronization protocols automatically update the local cache with any changes from the server, resolving the contradiction between reliable data synchronization and offline accessibility.
3Weight of moving object
If portable devices use lower performance components, then device portability and battery life are improved, but application execution capability deteriorates
Solution Approach 1:
The server acts as a mediator that performs all computationally intensive tasks, while the portable device only handles lightweight interface interactions. This allows the use of low-power, lightweight components in the portable device without compromising application execution capability, as the server handles all heavy processing requirements.
Solution Approach 2:
The portable device performs only the minimal necessary actions locally (interface rendering, user input handling), while excessive or complete processing is performed by the server. This partial action approach enables the device to maintain portability with low-power components while still supporting full application functionality through server assistance.
