Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a conveyor is used to remove metallic foreign matter from fluororesin, then the removal process can be automated, but the loss of fluororesin increases significantly
Solution Approach 1:
A magnetic field is introduced as an intermediary force to remove metallic foreign matter without direct mechanical contact. The magnet attracts metal particles through the fluororesin mass, allowing separation while the fluororesin flows freely downward, minimizing loss compared to conveyor-based mechanical systems
Solution Approach 2:
The mechanical conveyor system is replaced with a gravity-based flow system combined with magnetic field application. Instead of mechanically transporting and filtering the fluororesin, the method allows it to flow by gravity while a magnet removes metal particles, reducing mechanical stress and material loss
2Device complexity
If conventional methods are used to remove metallic foreign matter, then the process is simple, but the removal accuracy is insufficient for integrated metal and fluororesin contamination
Solution Approach 1:
The magnetic field is applied locally at the point where fluororesin flows downward, creating a targeted removal zone. This localized application ensures that metal particles are attracted and removed precisely where needed, while the rest of the process remains simple and unchanged
