Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If optimization processing is performed completely before starting production, then production efficiency is improved, but production start time is delayed
Solution Approach 1:
The system performs preliminary optimization processing to generate an initial production job before production starts, then continues optimization during production. This allows production to start with a sufficiently optimized job while still benefiting from ongoing optimization improvements.
Solution Approach 2:
The optimization process transitions from a static pre-production-only approach to a dynamic continuous process that operates during production. The production job is updated in real-time based on ongoing optimization results, allowing the system to adapt and improve efficiency throughout the production run.
2Loss of time
If production is started with incomplete optimization, then production start time is advanced, but production efficiency decreases and production time increases
Solution Approach 1:
The optimization processing continues continuously during production rather than stopping before production starts. This ensures that the production job is constantly being improved, maintaining high production efficiency throughout the production run while allowing production to start immediately.
Solution Approach 2:
The system implements a feedback loop where optimization results are continuously evaluated and used to update the production job. The production management device receives optimization results, determines whether to update the production job, and applies improvements in real-time, ensuring production efficiency is maintained and enhanced during production.
3Productivity
If feeder arrangement is changed based on optimized production job, then production efficiency is improved, but production process complexity increases
Solution Approach 1:
The automatic exchanging device autonomously changes feeder arrangements based on optimization results without requiring manual intervention. The system self-manages the complexity of coordinating multiple component mounters and feeders, translating optimized production jobs into automatic feeder exchange operations.
Solution Approach 2:
The production management device acts as an intermediary between the optimization device and the automatic exchanging device. It receives optimization results, determines update timing, and coordinates feeder exchanges, thereby managing the complexity of the production process while enabling efficiency improvements.

AI summary
An optimization processing computer (61), before production starts, sends a production job on which optimization processing was performed but is incomplete to each component mounter (12), causes an automatic exchanging device (26) to operate so as to change the feeder arrangement of each component mounter (12) to a feeder arrangement specified in the production job, then causes each component mounter to operate so as to start production. After production is started, optimization processing on the production job is continued by the optimization processing computer, and during production, an updated production job for which optimization has progressed is acquired from the optimization processing computer so as to update the production job being executed by each component mounter, then the automatic exchanging device is operated so as to change the feeder arrangement of each component mounter to a feeder arrangement specified in the production job, then production continues.
