Display Control Apparatus for File Name Omission and Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic music apparatuses face challenges in displaying full character strings for file names and paths due to limited screen size, leading to incomplete display and difficulty in distinguishing between data items, and automatic file naming schemes do not consider sorting order, making it hard to find newly created files amidst numerous stored files.
Innovation Solution
A display control apparatus that compares character string lengths with the display area width and omits parts of character strings to include crucial identifying portions, and an automatic file naming scheme that assigns names with a predetermined character at the leading or trailing end based on sorting order to ensure newly created files are easily identifiable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the entire character string is displayed, then complete information is provided, but the display area is exceeded and other information cannot be shown
Solution Approach 1:
The patent extracts and displays only the essential identifying portions of character strings (such as file names and relevant path components) while omitting non-essential parts. This allows the display to show complete identification information without exceeding the limited display area, resolving the contradiction between information completeness and display space constraints.
2Area of stationary object
If character string portions are omitted to fit display area, then display capacity is improved, but data identification becomes difficult
Solution Approach 1:
The patent applies local quality by selectively preserving essential identifying portions (such as file names and key path components) while omitting non-essential parts. This ensures that the most important information for data identification is always displayed, maintaining identification capability while optimizing display area utilization.
3Productivity
If automatic file naming is used, then file creation efficiency is improved, but finding newly created files among sorted files becomes difficult
Solution Approach 1:
The patent uses visual differentiation (analogous to color changes) by displaying automatically assigned file names with different formatting or highlighting compared to user-assigned names. This allows users to quickly identify newly created files with automatically assigned names among sorted files, maintaining both creation efficiency and ease of location.

AI summary
When a list of file names is to be displayed on a display device, a comparison is made between a necessary display width of each of the file names and a width of a display area of the display device. For each of the file names having a necessary display width greater than the width of the display area, it is checked whether the file name contains a particular character string portion of a predetermined type, and, if so, the file name is displayed in the list in a partly-omitted display style where a leading end portion, particular character string portion and extension of the file name are left in the list with the other part of the character string omitted. The particular character string portion can function as an important element for identifying the data item in question.
