Injection Molding Screen Font Compression for Multilingual Readability

Solution Overview

Problem

Injection molding machines face difficulties in displaying character strings in multiple languages without reducing font size, leading to readability issues when the string exceeds the allocated display width.

Innovation Solution

A controller for injection molding machines that adjusts the horizontal width ratio of the font while maintaining the vertical width ratio, allowing for easy readability of character strings by reducing the font size only horizontally when necessary, and providing a character string management database to manage and display shortened strings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the font size is reduced to display the entire character string in the fixed display field, then the character string can be fully displayed, but the readability becomes poor

Engineering Contradiction:

Improvecharacter string display completenessVSAvoidreadability

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent applies local quality by differentiating the scaling behavior of font dimensions. Specifically, the horizontal width of the font is reduced to accommodate longer character strings within the fixed display field, while the vertical width is maintained at its original size. This selective dimensional adjustment ensures that the entire character string is displayed without compromising vertical readability, thereby resolving the contradiction between display completeness and readability.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If the display field width is increased to accommodate longer character strings, then readability is maintained, but the screen layout design becomes fixed and inflexible

Engineering Contradiction:

ImprovereadabilityVSAvoiddisplay field flexibility

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent employs parameter changes by dynamically adjusting the horizontal width parameter of the font based on the length of the character string to be displayed. When a character string exceeds the display field width, the system reduces the horizontal font width parameter while keeping the vertical parameter constant. This parameter adjustment allows the display field to adapt to different language and text length requirements without altering the fundamental screen layout design, thus maintaining both readability and flexibility.

Inventive Principle:

Principle #35Parameter changes

3Loss of information

If the vertical width of the font is reduced along with the horizontal width, then the character string fits in the display field, but the font becomes too small to read comfortably

Engineering Contradiction:

Improvecharacter string display completenessVSAvoidreadability

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent applies local quality by differentiating the scaling behavior of font dimensions. Specifically, the horizontal width of the font is reduced to accommodate longer character strings within the fixed display field, while the vertical width is maintained at its original size. This selective dimensional adjustment ensures that the entire character string is displayed without compromising vertical readability, thereby resolving the contradiction between display completeness and readability.

AI summary

A controller for an injection molding machine includes a display device displaying various screens of the injection molding machine and configured to receive a screen operation by a user through an operation interface. The controller is configured to, in a case where it is determined that a display character siring exceeding a display width in a standard font size is to be displayed in a character string display field provided on the various screens, cause the display device to display the entire display character string in a font with a reduced horizontal width ratio in a state where a vertical width ratio of the font is maintained.
