Solution Overview

Problem

Users of electronic devices face inconvenience when the display format of an e-book changes, as they may lose their reading position or miss parts of the document, requiring them to search for the missing content, disrupting their reading experience.

Innovation Solution

A method and apparatus that detect changes in the display format of e-books on electronic devices, allowing users to easily locate missing content by displaying the differences between the original and changed formats, enabling users to distinguish between content displayed before and after the change.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the display format of an e-book changes (e.g., text size, font size, line spacing), then the device can accommodate different user preferences and display requirements, but the user loses their reading position and may miss parts of the document

Engineering Contradiction:
Improvedisplay format adaptabilityVSAvoidreading position information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system performs preliminary action by detecting format changes before the user can lose their reading position, and proactively displays a notification showing the difference between content before and after the change. This prevents the user from actually losing their place by alerting them to the change and showing them what content may have been affected.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by displaying a notification that shows the user the difference between content displayed before and after the format change. This feedback mechanism informs the user about potential content loss or position changes, allowing them to understand what has changed and take appropriate action to locate their reading position.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the display format changes, then the e-book can be optimized for different reading conditions and user needs, but the user must search for their reading position and missing content

Engineering Contradiction:
Improvereading accessibilityVSAvoidtime to locate reading position
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary action by detecting format changes before the user needs to search for their reading position. By proactively displaying a notification with the difference between content before and after the change, the system prepares the user in advance, eliminating the need for time-consuming searches.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides immediate feedback about format changes and their impact on content display. This feedback includes showing the user the difference between content before and after the change, enabling them to quickly understand what content may have been affected and locate their reading position without extensive searching.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If the display format is changed to accommodate user input, then the reading experience can be customized, but the user may miss parts of the displayed e-book

Engineering Contradiction:
Improvedisplay customizationVSAvoidcontent visibility
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system implements feedback by displaying a notification that shows the user the difference between content displayed before and after the format change. This feedback mechanism ensures content visibility by alerting the user to potential content loss and showing them exactly what content may have been affected by the customization, allowing them to review and locate any missed parts.

Inventive Principle:
Principle #23Feedback
