Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional encapsulant compound processing is used without magnetic inserts, then the processing equipment operates simply, but foreign material and contamination remain in the encapsulant compound
Solution Approach 1:
Magnetic inserts are introduced as intermediary components within the kneader and extruder equipment. These inserts generate magnetic fields that act as mediators to attract and capture ferrous foreign materials during the encapsulant compound processing, thereby improving cleanliness without fundamentally changing the equipment's core function
Solution Approach 2:
The magnetic inserts alter the magnetic field parameters within the processing equipment. By introducing controlled magnetic fields through the inserts, ferrous particles are selectively attracted and captured from the encapsulant compound, changing the material composition parameters to achieve cleaner output
2Reliability
If magnetic inserts are added to capture foreign material, then encapsulant compound cleanliness improves, but the equipment structure becomes more complex
Solution Approach 1:
The magnetic insertion system is segmented into modular components that can be independently installed and removed from the kneader and extruder. This segmentation allows the magnetic cleaning function to be added as a separate module rather than redesigning the entire equipment structure, thereby limiting the increase in overall system complexity
Solution Approach 2:
The magnetic inserts are designed as replaceable, cost-effective components rather than permanent integrated features. When the magnetic inserts become saturated with foreign material or lose effectiveness, they can be easily replaced with new inserts, avoiding the need for complex cleaning mechanisms or equipment overhaul
