Solution Overview

Problem

Current collaborative document management systems require users to manually download and upload documents multiple times and perform format conversions to add comments, making the process inefficient and cumbersome, especially in cloud environments.

Innovation Solution

A remote server system that allows real-time commenting and synchronization of comments across platforms without the need for users to download documents, by saving documents in their native format and incorporating comments directly into the document structure, enabling simultaneous access and editing across devices without dedicated local applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users manually download and upload documents to add comments, then comments can be added to the document, but the operation time and complexity increase significantly

Engineering Contradiction:
Improvecomment synchronizationVSAvoidmanual download and upload time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system enables self-service by allowing users to add comments directly through the web interface without manual download/upload operations. The comment addition process is automated, with the system handling document retrieval, comment insertion, and synchronization automatically, eliminating the need for user-initiated manual file transfers.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary actions by pre-loading document data and maintaining it in an editable state within the web interface. The document is prepared and kept accessible in the browser's memory or local storage, allowing immediate comment addition without requiring prior download or subsequent upload operations.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If documents are converted to different formats for cloud storage, then documents can be stored remotely, but format conversion complexity and time increase

Engineering Contradiction:
Improvecross-platform accessVSAvoidformat conversion process
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system achieves universality by implementing a universal document representation format that can store and display various document types (Word, PDF, etc.) without requiring format conversion. The web interface and server communicate using a standardized data structure that preserves the original document format while enabling cross-platform access and editing capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Manufacturing precision

If dedicated local applications are required for document editing, then document formatting is preserved, but device requirements and access complexity increase

Engineering Contradiction:
Improvedocument formattingVSAvoidaccess convenience
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The system introduces an intermediary layer between the user and the document that handles formatting preservation without requiring dedicated applications. The web interface acts as a mediator, interpreting and rendering document formatting through HTML/CSS while maintaining the original document's structure and appearance, thus eliminating the need for native applications.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Systems and methods disclosed herein provide a mechanism for synchronizing comments to an electronic document. An example method may include, receiving, by a processing device of a server, a request of a first user device to access an electronic document that is stored on a remote storage system in a native document format; providing for presentation, via a remote document access user interface at the first user device, data of the electronic document; receiving comment data comprising a plurality of comments of one or more user devices; sending, by the processing device of the server, a message comprising the comment data to a second user device for incorporation into a local copy of the electronic document; and providing, by the processing device of the server, the plurality of comments to the first user device for presentation with the data of the electronic document.
