Solution Overview

Problem

In a collaborative document editing scenario where an electronic document is divided into multiple division documents by one user while another user is editing, the screen display of the original document pages becomes inconsistent, preventing the second user from viewing the correct pages of the original document.

Innovation Solution

A document editing apparatus and method that includes a control unit to display operators for accessing division documents different from the one being edited, using a co-editing database to track page movements, and providing operators for preceding or following pages in the original document, even if they belong to different division documents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a second user divides an original document into multiple division documents while a first user is editing, then the document can be organized into separate sections, but the first user cannot display pages from division documents other than the current one on the editing screen

Engineering Contradiction:
Improvedocument organization flexibilityVSAvoidscreen display accessibility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The editing screen is designed to display pages from multiple division documents simultaneously. The display control unit enables the editing screen to function not only for the current division document but also for other division documents, allowing users to view and edit pages from different division documents on the same screen without switching screens or applications.

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

2Ease of manufacture

If the original document is divided into multiple division documents, then document management becomes more structured, but information about pages in the original document becomes fragmented across different division documents

Engineering Contradiction:
Improvedocument management efficiencyVSAvoidoriginal document page continuity
Core Design Contradiction:
Ease of manufactureVSLoss of information

Solution Approach 1:

The system provides feedback to users about the original document structure even when divided into multiple division documents. The display control unit maintains awareness of which pages belong to the original document and enables appropriate display, ensuring users understand the relationship between division documents and the original document while preserving page continuity information.

Inventive Principle:
Principle #23Feedback

AI summary

A document editing apparatus includes: a processor configured to: in a case where a second user performs an operation of dividing an original document including plural pages into plural division documents while a first user is editing the electronic original document, display an operator for displaying another division document different from a division document including a page being edited by the first user, on a screen on which the page being edited is displayed.
