Solution Overview

Problem

Current e-book-reading devices fail to enable users to easily navigate electronic books, as existing navigation interfaces are slow and cumbersome, lacking the intuitive page-flipping and affinity-based navigation features of traditional paper books.

Innovation Solution

The development of e-book-reading devices with manual selectors, such as flexible tabs, brush selectors, and flex sensors, that allow for variable and tactile page selection, combined with affinity-based navigation, enabling users to quickly scan through pages using object recognition and pre-rendered images, and navigate based on page affinities like user interactions and references.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If page-by-page navigation is used, then users can navigate through each page, but the navigation becomes slow and ponderous

Engineering Contradiction:
Improvepage navigation easeVSAvoidnavigation speed
Core Design Contradiction:
Ease of operationVSSpeed

Solution Approach 1:

The system pre-renders thumbnail images of multiple pages in advance and displays them in a scrollable list, allowing users to directly select the desired page without sequential navigation. This preliminary preparation of page previews enables instant access to any page, resolving the contradiction between ease of operation and navigation speed.

Inventive Principle:
Principle #10Preliminary action

2Loss of information

If content-based navigation is used, then users can search for specific terms, but the process becomes slow due to term selection through typing interface

Engineering Contradiction:
Improveinformation retrieval accuracyVSAvoidtime to locate page
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system replaces the mechanical typing interface with touch-based selection of pre-displayed page thumbnails. Users can visually identify and tap the desired page directly from the rendered list, eliminating the time-consuming process of typing search terms while maintaining accurate information retrieval through the visual preview system.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Productivity

If chapter-based navigation is used, then users can quickly jump to chapter start, but users cannot easily access specific portions within a chapter

Engineering Contradiction:
Improvenavigation efficiencyVSAvoidnavigation flexibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The system segments the book into individual page thumbnails that are separately renderable and selectable. This segmentation allows users to navigate to any specific page within a chapter by directly selecting its thumbnail, providing both the efficiency of direct access and the flexibility to reach any portion of the content, not just chapter beginnings.

Inventive Principle:
Principle #1Segmentation

4Reliability

If search term navigation is used, then users can scan pages with the term, but the process is slow due to term selection and common terms reduce effectiveness

Engineering Contradiction:
Improvenavigation accuracyVSAvoidnavigation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system creates visual copies (thumbnails) of page content that display key information and layout. Users can scan these thumbnail copies to identify the desired page visually, eliminating the need for text-based search terms. This copying approach maintains navigation accuracy through visual recognition while dramatically simplifying the operation to a simple tap gesture.

Inventive Principle:
Principle #26Copying

AI summary

This document describes techniques and apparatuses enabling affinity-based page navigation. These techniques and apparatuses enable page navigation, such as page flipping, page searches, and other navigation based on affinities associated with various pages. These affinities can include a reference to a page, such as a link or quotation in a social networking service, an encyclopedia, a webpage, an article, a newspaper, or a blog. These affinities can also or instead include usage, such as how many users have read, highlighted, dog-eared, or bookmarked a page.
