Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If maintenance is performed based on fixed schedules regardless of usage conditions, then maintenance timing can be determined easily, but maintenance accuracy decreases and producibility decreases due to inappropriate maintenance timing
Solution Approach 1:
The system changes the parameter basis for maintenance scheduling from fixed time intervals to dynamic parameters including operating hours, production volume, and actual device condition data. This allows maintenance timing to adapt to varying usage conditions while maintaining ease of operation through automated parameter monitoring and analysis.
Solution Approach 2:
The system implements feedback loops where device operation data is continuously collected, analyzed, and used to adjust maintenance schedules. The analysis unit processes operating conditions and provides feedback recommendations for optimal maintenance timing, creating a closed-loop system that improves maintenance accuracy while maintaining operational simplicity.
2Productivity
If maintenance is delayed to maintain productivity, then producibility increases in short term, but device reliability decreases leading to unexpected failures
Solution Approach 1:
The system performs preliminary analysis of device condition data and operating parameters to predict future maintenance needs before failures occur. By analyzing trends in device performance and operating conditions, the system provides advance warning and scheduling recommendations that allow maintenance to be performed proactively, maintaining both productivity and reliability.
3Measurement precision
If comprehensive device monitoring is implemented to improve maintenance accuracy, then maintenance timing precision increases, but system complexity increases
Solution Approach 1:
The system employs a multi-functional analysis unit that handles multiple types of data (operating hours, production volume, device parameters, error logs) through a single integrated analysis platform. This universal approach achieves high maintenance timing precision without proportionally increasing system complexity, as the same hardware and software infrastructure serves multiple monitoring and analysis functions.

AI summary
Provided is a device management system to suppress decreases in producibility. A device management system (100) manages a plurality of production-line-configuring devices (112) configuring a production line to produce products (P), and has a device state data storage part (90d), an analysis part (90i), and a server output part (90k). The production-line-configuring devices (112) include a combination weighing machines (10) to weigh the products (P), a bag-making and packaging machine (20) to package the products (P), and a boxing device (40) to box the packaged products (P) into boxes. The device state data storage part (90d) accumulates device state data (DT), which is information pertaining to the components included in the production-line-configuring devices (112). The analysis part (90i) performs an analysis process to analyze the device state data (DT) accumulated in the device state data storage part (90d). The server output part (90k) outputs maintenance information (IF), which pertains to maintenance of the components, on the basis of the results of the analysis process.
