Manufacturing Process Management System with Time-Aligned Graph Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturing process management systems lack the ability to effectively visualize and analyze manufacturing statuses across multiple processes, making it difficult for users to identify and inspect specific processes in real-time.
Innovation Solution
A manufacturing process management system that displays a graph representing elapsed time for each manufacturing process, allowing users to specify and display corresponding captured images of processes based on designated positions, enabling visualization and analysis of manufacturing statuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If manufacturing process data is accumulated and visualized on graphs, then manufacturing status monitoring capability is improved, but the system complexity increases
Solution Approach 1:
The patent uses captured images as visual copies of the actual manufacturing processes. These images are stored and can be displayed on the graph to represent the state of each process, providing intuitive visual information without requiring complex real-time monitoring systems for each individual process.
Solution Approach 2:
The patent introduces a time code as an intermediary element that links the graph timeline with captured images. The time code serves as a mediator that allows users to correlate visual process states with specific time points on the manufacturing timeline, simplifying the interface between data visualization and process monitoring.
2Ease of operation
If captured images are stored for all manufacturing processes, then process inspection capability is improved, but storage requirements and data management complexity increase
Solution Approach 1:
The patent applies local quality by associating specific captured images with specific time periods or process stages. Instead of uniformly storing all possible images, the system selectively stores and displays images relevant to particular processes or time codes, reducing overall data volume while maintaining inspection capability where needed.
3Measurement precision
If the graph displays detailed information for each manufacturing process, then analysis precision is improved, but readability and ease of understanding decrease
Solution Approach 1:
The patent uses visual differentiation through captured images displayed at different positions on the graph. Each process stage can be represented with its corresponding image, providing visual cues that help users distinguish between different processes and their states without relying solely on text or numerical data.

AI summary
A manufacturing process management system includes: a display circuit; and a processor configured to: display, on the display circuit, a graph which represents an elapsed time from a start to a finish of each of a plurality of manufacturing processes through which a product is manufactured, based on information of starting times and finishing times of the manufacturing processes, in a state where the plurality of manufacturing processes are divided into each of manufacturing processes in an execution order and time axes are aligned in a same direction; specify, from among captured images of the plurality of manufacturing processes which are stored in a storage, a captured image which corresponds to the manufacturing process for a designated position on the displayed graph; and display the specified captured image on the display circuit.
