Solution Overview

Problem

Existing methods for displaying electronic books with multiple contents, such as comic books, on mobile terminals do not effectively optimize the spacing between frames for easy readability.

Innovation Solution

A method to determine a suitable distance between display targets in electronic books by calculating the sum of non-display-target regions and comparing it with a predetermined distribution function to ensure appropriate spacing, allowing for easy viewing on mobile devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If frames are displayed with fixed spacing on mobile terminals, then the display layout is simple, but the readability is poor because the spacing does not account for non-display-target regions

Engineering Contradiction:
ImprovereadabilityVSAvoidspacing calculation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent calculates and stores the total widths of non-display-target regions for each frame in advance, before actual display. This preliminary calculation allows the reading distance determination unit to quickly select appropriate spacing based on pre-computed data, rather than performing complex calculations during display, thus improving readability while maintaining implementation simplicity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces a new dimension of measurement by calculating the total width of non-display-target regions (margins, captions, etc.) in addition to the visible frame content. This additional dimensional information enables more accurate spacing determination that accounts for all visual elements, not just the main frame content, thereby improving readability

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If the distance between frames is reduced to fit more content on screen, then the productivity increases, but the readability decreases due to insufficient spacing

Engineering Contradiction:
Improvecontent display capacityVSAvoidreadability
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent dynamically adjusts the display distance parameter based on the total width of non-display-target regions. By changing the spacing parameter according to the specific characteristics of each frame (including margins, captions, and other non-display elements), the system optimizes both content capacity and readability, allowing more content to be displayed when spacing is minimized while maintaining readability when spacing is increased

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If uniform spacing is applied to all frames, then the device complexity is low, but the manufacturing precision of layout is poor

Engineering Contradiction:
Improvelayout precisionVSAvoidspacing determination complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies different spacing distances to different frames based on their specific non-display-target region widths. Instead of uniform spacing, each frame's distance from others is locally optimized according to its unique characteristics (margins, captions, etc.), achieving high layout precision. The reading distance determination unit selects appropriate distances from a set of candidate distances based on pre-calculated non-display region data

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent performs preliminary calculation of non-display-target region widths and stores this data before actual display. This advance preparation enables the system to quickly determine precise spacing without complex real-time calculations, achieving high layout precision while keeping the implementation relatively simple through pre-computed data lookup

Inventive Principle:
Principle #10Preliminary action

AI summary

[Problem] An object is to provide an easy-to-read electronic book by improving how an electronic book having a plurality of contents, such as a comic book including a plurality of partial regions (frames), is displayed on a display screen of a mobile terminal or the like. [Solution] Provided is a method for placing a first content and a second content on a display screen at a distance D along a Y-axis in an orthogonal coordinate system formed by an X-axis and the Y-axis orthogonal to each other, the first content including a first display target, the second content including a second display target. The method includes identifying a first non-display-target region which is part of a non-display-target region obtained by excluding a region of the first display target from a region of the first content and which is located on the second content side, identifying a second non-display-target region which is part of a non-display-target region obtained by excluding a region of the second display target from a region of the second content and which is located on the first content side, calculating a plurality of total widths each of which is a sum of a width of the first non-display-target region in a direction of the Y-axis and a width of the second non-display-target region in the direction of the Y-axis, the widths being at a same X-coordinate, and determining the distance D based on the plurality of total widths and a predetermined reference.
