Manufacturing Timeline Visualization for Step Factor Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current visualization systems for manufacturing status fail to effectively display changes in step characteristic factors across multiple manufacturing steps, making it difficult to monitor and manage production efficiently.
Innovation Solution
A visualization system that creates line segments connecting start and end times of manufacturing steps and uses display objects to represent changes in step characteristic factors, allowing for clear visualization of changes and their attributes on a timeline.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a Gantt chart is used to visualize manufacturing status, then the timeline and sequence of manufacturing steps can be displayed, but changes in step characteristic factors cannot be effectively visualized
Solution Approach 1:
The patent merges the Gantt chart timeline visualization with step characteristic factor change visualization into a single integrated display. The display object combines temporal information (when changes occur) with characteristic factor information (what changed and by how much) using symbolic representations like icons, colors, and annotations overlaid on the Gantt chart structure, eliminating the need for separate visualization systems.
2Loss of information
If multiple display objects are added to show step characteristic factors, then information completeness improves, but readability and ease of operation deteriorate
Solution Approach 1:
The patent applies local quality by providing detailed step characteristic factor information only at specific locations where changes occur, rather than uniformly across the entire timeline. Display objects are selectively placed at time points where characteristic factors change, using localized icons, color codes, and annotations that provide detailed information precisely where needed without cluttering the entire visualization.
Solution Approach 2:
The patent uses color changes and symbolic representations in display objects to encode different types of step characteristic factor changes. Different colors, icons, or visual styles represent different categories or magnitudes of changes, allowing operators to quickly interpret multiple pieces of information through visual patterns rather than reading detailed numerical data for each change.

AI summary
A visualization system includes: a first creation section configured to create, for each product manufacturing unit, a line segment connecting a start or end time of a first step to a start or end time of a subsequent second step; a second creation section configured to identify, based on a change log of a step characteristic factor at each manufacturing step, any change in step characteristic factor observed at the first and second steps, and to create a display object representing magnitude of the change in step characteristic factor or including a region representing an attribute of the changed step characteristic factor; and a display control section configured to cause: to display a line segment representing the time axis, created by the first creation section, and the display object, and to display the display objects over positions of the start or end times on time axes of their associated steps.
