Manufacturing Timeline Visualization for Abnormality Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visualization apparatuses in manufacturing lines face difficulties in displaying a visualization image that allows users to readily recognize abnormalities in manufacturing status, as they struggle to differentiate between normal and abnormal processing times across multiple manufacturing apparatuses.
Innovation Solution
A display method that visualizes manufacturing status by identifying and plotting starting and ending times of processing on temporal axes for each apparatus, connecting these points to show normal and ideal processing times, allowing for the display of areas that indicate deviations from ideal processing, thereby making it easier to recognize abnormalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional visualization methods are used to display manufacturing status, then the system can show processing times, but users cannot readily recognize abnormalities in the manufacturing status
Solution Approach 1:
The patent creates a copy of the actual manufacturing process timeline and overlays it with an ideal reference timeline. By copying the real processing data and comparing it visually against the ideal scenario, users can immediately spot deviations and abnormalities without complex analysis, thus improving both detection accuracy and visual recognition ease.
Solution Approach 2:
The patent employs color coding to represent different processing states and deviations. Areas where actual processing deviates from ideal processing are highlighted with distinct colors, making abnormalities visually prominent and easily recognizable, thereby resolving the contradiction between precise abnormality detection and ease of visual recognition.
2Reliability
If processing times are displayed without reference to ideal times, then all processing data is visible, but users cannot determine whether processing is in abnormal status
Solution Approach 1:
The patent introduces an ideal processing timeline as an intermediary reference element between the actual processing data and the user's judgment. This intermediary provides the necessary context for evaluating whether actual processing times are abnormal, enabling reliable status determination while preserving all original processing information through the overlay comparison.
3Measurement precision
If only numerical processing time data is shown, then precise measurements are available, but visual recognition of abnormalities is difficult
Solution Approach 1:
The patent transforms one-dimensional numerical processing time data into a two-dimensional visual representation by plotting actual and ideal timelines on a graphical interface. This dimensional transformation allows precise measurement data to be visually compared, making abnormalities immediately apparent while retaining measurement precision.

AI summary
A display method of a manufacturing status to visualize a manufacturing status of products each manufactured through processing performed by a plurality of apparatuses included in a manufacturing line includes identifying, for each product to be manufactured in a certain manufacturing unit, a starting time or an ending time or both of the processing performed on the product by a first apparatus and a starting time or an ending time or both of the processing performed on the product by a second apparatus based on log information of the first apparatus and log information of the second apparatus, the first and the second apparatuses being included in the manufacturing line, the second apparatus performing the processing after the processing performed by the first apparatus, using a processor.
