Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If single-stage electrode arrangement is used, then device complexity is reduced, but processing efficiency decreases and unprocessed materials increase
Solution Approach 1:
The electrode arrangement is divided into multiple stages (first electrode arrangement region and second electrode arrangement region) along the material flow direction. Each stage contains electrodes that process materials sequentially, increasing the probability that material particles will pass through the arc discharge region and be fully processed, thereby resolving the contradiction between processing efficiency and device complexity.
2Productivity
If arc discharge temperature is insufficient, then energy consumption is reduced, but evaporation efficiency decreases and production yield drops
Solution Approach 1:
The multi-stage electrode arrangement ensures continuous and progressive processing of material particles through multiple arc discharge regions. This continuous action increases the cumulative energy input and processing effectiveness, improving evaporation efficiency and production yield while maintaining reasonable energy consumption levels.
3Productivity
If material particles are not fully evaporated, then energy consumption is reduced, but processing efficiency decreases and unprocessed materials increase
Solution Approach 1:
The patent extends the processing from a single-point arc discharge to a multi-stage spatial arrangement along the material flow direction. This dimensional extension ensures that material particles undergo progressive evaporation and processing in sequence, improving processing efficiency while preventing energy waste from incomplete evaporation.
