Mounting Delay Analysis Screens for Preparation Time Deviations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing analysis methods fail to accurately identify the cause of delays in the mounting step of a circuit board production process, as indicated by a time chart, which does not account for actual time deviations from scheduled times.
Innovation Solution
An analysis support device and system that includes a display control section to show first and second screens displaying device and preparation actual vs. scheduled times, allowing users to analyze delays through graphical and tabular representations, and optionally showing device abnormalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a time chart is displayed to show the state of the mounting step, then the user can view the scheduled time and actual result time, but the user cannot analyze the cause of the delay
Solution Approach 1:
The display system is segmented into multiple screens: a first screen showing the time chart with scheduled and actual times, and a second screen showing detailed preparation step information. This segmentation allows the user to access cause analysis information without overwhelming the interface with all data at once, resolving the contradiction between providing comprehensive information and maintaining simple device complexity.
Solution Approach 2:
The system transitions from a two-dimensional time chart view to a multi-dimensional analysis by adding a second screen dimension that displays preparation step details. This dimensional expansion enables cause analysis by showing the relationship between preparation steps and mounting step delays, thereby recovering lost information without significantly increasing device complexity.
2Loss of information
If detailed preparation step information is always displayed, then the user can identify delay causes, but the interface becomes complex and difficult to operate
Solution Approach 1:
The display system dynamically switches between different screens based on user needs. The first screen provides a simple time chart overview, while the second screen provides detailed preparation step information. This dynamic switching maintains ease of operation by showing only relevant information at each moment, while still providing access to complete delay cause information when needed.
Solution Approach 2:
The system prepares detailed preparation step information in advance but keeps it hidden until the user needs it. By pre-processing and organizing the data, the system can quickly display detailed information on the second screen when requested, maintaining ease of operation while ensuring delay cause information is readily available when needed.
3Measurement precision
If only the mounting step time is monitored, then the interface remains simple, but the cause of delay cannot be identified
Solution Approach 1:
The preparation step information acts as an intermediary between the simple time chart display and the detailed cause analysis. By introducing this intermediate layer that shows preparation step timing and status, the system enables precise delay cause identification without directly complicating the main monitoring interface, thus improving measurement precision while controlling device complexity.

AI summary
An analysis support device includes a display; a first display control section configured to display a first screen including a device scheduled image and a device actual result image on the display when a device actual result time at which a mounting device actually performs a mounting step of mounting a component on a substrate is delayed; and a second display control section configured to display a second screen including a preparation scheduled image and a preparation actual result image on the display when a predetermined first instruction is given by a user after the first screen is displayed on the display, the preparation scheduled image indicating a preparation scheduled time at which a preparation step, which is preparation for the mounting step, is to be performed, and the preparation actual result image indicating a preparation actual result time at which the preparation step is actually performed.
