Solution Overview

Problem

Existing systems fail to clearly distinguish and display the wait time and work time associated with component replenishment in board work machines, making it difficult for users to grasp the duration and efficiency of the replenishment process.

Innovation Solution

An operation status display device and method that acquires and displays the wait time and work time for component replenishment in a graph format, distinguishing between the time from when an article is insufficient to when replenishment starts, and the time taken to complete replenishment, for each unit of production time, allowing for totalization and display of insufficient article numbers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the component supply wait time is displayed as a single aggregated value, then the display is simple and easy to understand, but the details of wait time from component insufficiency to replenishment start and work time from replenishment start to completion cannot be grasped

Engineering Contradiction:
Improveloss of replenishment time detailsVSAvoidcomplexity of time measurement system
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent segments the component supply wait time into two distinct time periods: (1) wait time from component insufficiency detection to replenishment start, and (2) work time from replenishment start to completion. This segmentation allows the display device to show detailed time information for each phase separately, resolving the contradiction between providing detailed information and maintaining system simplicity.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If the display shows detailed breakdown of replenishment times for each unit time, then the information completeness is improved, but the difficulty of detecting and measuring increases

Engineering Contradiction:
Improveprecision of time measurementVSAvoiddifficulty of time data collection
Core Design Contradiction:
Measurement precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The patent implements preliminary action by having the display control section pre-prepare and organize time data into distinguishable categories (wait time and work time) before display. The system automatically measures and separates these time periods in advance, so that when data is presented to the user, it is already structured and ready for clear visualization, reducing the perceived measurement difficulty.

Inventive Principle:
Principle #10Preliminary action

3Quantity of substance

If the system tracks and displays insufficient article numbers along with time data, then the comprehensiveness of production status monitoring is improved, but the device complexity increases

Engineering Contradiction:
Improvenumber of tracked parametersVSAvoidcomplexity of data processing system
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent merges multiple data elements (wait time, work time, and insufficient article numbers) into a single integrated display interface. By combining these different types of information in one unified view, the system improves comprehensive monitoring capability while avoiding the complexity that would result from separate displays for each parameter.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An operation status display device is an operation status display device configured to display an operation status of a board work machine configured to perform predetermined board work on a board, in which an operator replenishes an article to be used in production of a board product using the board work machine to produce the board product, and the operation status display device includes an acquisition section and a display section. The acquisition section is configured to acquire a first time, which is a wait time from when the article is insufficient in the board work machine to when the operator starts replenishment work of the article, and a second time, which is a work time from when the operator starts the replenishment work to when the article is replenished in the board work machine. The display section is configured to display the first time and the second time in a graph in a distinguishable manner, for a stop time of the board work machine from when the article is insufficient in the board work machine to when the article is replenished.
