Sync Module Delegating Authorization to Client Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current synchronization services lack efficient file handling capabilities and are unaware of the synchronization techniques and offline access availability, leading to inefficient data synchronization between devices, especially when dealing with various file types and offline scenarios.
Innovation Solution
A sync module is configured to provide client applications with access to files by delegating synchronization authorization and managing local offline versions, allowing real-time synchronization and offline access, leveraging the sophisticated file handling capabilities of client applications while mitigating the limitations of synchronization services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a synchronization service is used to manage file synchronization, then centralized control and coordination between devices are improved, but file handling efficiency and sophistication deteriorate compared to client applications
Solution Approach 1:
The system divides synchronization responsibilities into two segments: the sync module handles centralized coordination and metadata management, while the client application handles sophisticated file handling operations. This segmentation allows each component to specialize in its strength, resolving the contradiction between centralized control and file handling efficiency.
Solution Approach 2:
The sync module acts as an intermediary that provides synchronization information (URLs, authorization tokens, metadata) to the client application, which then performs the actual file handling. This intermediary approach allows the system to maintain centralized control while leveraging the client application's sophisticated file handling capabilities.
2Extent of automation
If a synchronization service manages all synchronization operations, then coordination between multiple devices is improved, but awareness of synchronization techniques and offline access availability deteriorates
Solution Approach 1:
The sync module serves as an intermediary that maintains awareness of synchronization information (file URLs, authorization tokens, synchronization status) and makes this information available to the client application. This resolves the contradiction by having the intermediary manage coordination while preserving information awareness through structured data exchange.
Solution Approach 2:
The system implements feedback mechanisms where the sync module receives notifications from the web storage service about file changes and propagates this information to the client application. This feedback loop ensures that synchronization information awareness is maintained throughout the system while centralized coordination is preserved.
3Productivity
If client applications perform file synchronization directly, then file handling sophistication is improved, but awareness of web storage service and offline access availability deteriorates
Solution Approach 1:
The sync module acts as an intermediary that provides the client application with awareness of the web storage service through structured information (URLs, authorization tokens, metadata). This allows the client application to perform sophisticated file handling while maintaining awareness of the web storage service through the intermediary's information provision.
4Device complexity
If generic upload/download functionality is used in synchronization service, then system simplicity is improved, but adaptability to particular file types deteriorates
Solution Approach 1:
The sync module provides universal synchronization functionality (metadata management, authorization, coordination) that works across all file types, while the client application provides file-type-specific handling capabilities. This multi-functionality approach resolves the contradiction by having each component handle what it does best.
Solution Approach 2:
The system segments functionality into generic synchronization operations (handled by the sync module) and file-type-specific operations (handled by the client application). This segmentation maintains system simplicity in the core synchronization logic while enabling adaptability through the client application's specialized capabilities.
Data Source
AI summary
One or more techniques and/or systems are disclosed for providing a client application with access to a file based upon a local offline version of the file and/or web online version of the file. That is, a file may be shared/synchronized from a remote source, such as a web storage service. A web online version of the file may be maintained by the web storage service, while local offline versions of the file may be stored at client devices. A sync module comprising knowledge of the local and/or web versions of the file may provide a client application with access to the file based upon the local and/or web version of the file. The sync module may also delegate synchronization authorization to the client application given that the client application may comprise sophisticated file handling functionality.
