Chapter Range Recognition via Marker Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bookbinding techniques face difficulties in recognizing chapter ranges, especially for chapters with a small number of pages, as the existing methods require complex processes and struggle to make these ranges clearly visible on the book edge.
Innovation Solution
A data editing apparatus and program that displays chapter range images on the book edge by arranging them at different positions in the top-bottom direction, with a marker image edit unit emphasizing chapters with fewer pages, ensuring these chapters are easily recognizable by placing the marker image adjacent to or within the chapter range image, either orthogonally or within specific page ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If chapter range images are displayed by printing chapter images at ends of book sheets corresponding to each chapter, then chapter ranges can be recognized on the book edge, but chapters with a small number of pages become difficult to recognize
Solution Approach 1:
The patent applies local quality by introducing marker images with specific visual characteristics (different color, size, or style) that are selectively placed adjacent to chapter range images of chapters having a small number of pages. This localized enhancement makes only the problematic small chapters more recognizable without altering the display method for other chapters, thereby resolving the contradiction between maintaining standard chapter range display and improving recognition of small chapters.
2Reliability
If marker images are placed adjacent to chapter range images of chapters with few pages, then these chapters become easily recognizable, but the device complexity increases
Solution Approach 1:
The patent applies preliminary action by automatically determining during the data editing process whether a chapter has a small number of pages (comparing chapter page count against a predetermined threshold) and pre-arranging marker images adjacent to the corresponding chapter range images before printing. This automated preliminary classification and arrangement eliminates the need for manual intervention, thereby reducing the perceived complexity despite the enhanced functionality.
3Measurement precision
If chapter range images are arranged at different positions in the top-bottom direction, then chapter ranges can be distinguished, but the space required on the book edge increases
Solution Approach 1:
The patent applies dimensionality change by introducing marker images that extend in a direction orthogonal to the top-bottom arrangement of chapter range images. Instead of solely relying on vertical positioning to distinguish chapters, the marker images add a lateral dimension to the visual differentiation, allowing chapter ranges to be distinguished both by their vertical positions and by the presence/characteristics of adjacent marker images, thereby improving distinction without proportionally increasing the required book edge length.

AI summary
When data about plural book sheets, each belonging to one of plural chapters, are edited to bind the plural book sheets by a casing-in operation in such a manner that chapter range images, which indicate the respective ranges of the plural chapters, are displayed on an edge so that the chapter range images that are adjacent to each other are arranged at different positions from each other in the top-bottom direction, a marker image emphasizing the chapter range image is adjacent to the chapter range image indicating the range of a chapter having book sheets the number of which is less than or equal to a predetermined threshold.
