Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an article moving device is used to automatically supply articles to a board work machine, then the automation level is improved, but production stoppages may occur due to wait times for article replenishment
Solution Approach 1:
The system performs preliminary actions by having the article moving device transport articles to a standby position before they are actually needed by the board work machine. This advance preparation ensures that articles are ready for immediate transfer, eliminating wait times and preventing production stoppages while maintaining automated operation.
2Ease of operation
If the article moving device waits for the board work machine to stop before supplying articles, then the timing coordination is simplified, but the production efficiency deteriorates
Solution Approach 1:
The system maintains continuous useful action by enabling the article moving device to operate independently and continuously transport articles to a standby position, while the board work machine operates without interruption. This continuous operation in parallel for both devices eliminates idle wait times and maintains high productivity while simplifying timing coordination through spatial separation of operations.
3Speed
If the article is transported in advance to a position near the board work machine, then the supply speed is improved, but the device complexity increases
Solution Approach 1:
The article moving device is designed with multi-functionality to perform both long-distance transportation from storage and short-distance delivery to the board work machine. This universal design consolidates multiple functions into a single device, achieving fast article supply speed while minimizing the need for additional specialized equipment, thus controlling system complexity.

AI summary
The simulation device includes a simulation section and a calculation section. A simulation section is configured to simulate an operating status of a board work machine configured to perform predetermined board work on a board and produce a board product, and an operating status of an article moving device configured to supply an article needed for production of the board product to the board work machine based on a production plan of the board product. A calculation section is configured to calculate a production stop time of the board work machine caused by a wait time from when production of the board product by the board work machine is stopped to when the article is supplied by the article moving device based on a result of simulation by the simulation section.
