Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If no intermediate materials are used between the flying plate and substrate, then the manufacturing process is simpler, but local connections occur between the flying plate and substrate causing incomplete coating
Solution Approach 1:
The patent introduces a transmission medium (gas or liquid) as an intermediary between the flying plate and substrate. This medium carries metal droplets from the flying plate to the substrate surface, preventing direct contact while ensuring complete and uniform coating coverage.
2Productivity
If the flying plate directly impacts the substrate, then the process is more direct, but local connections occur reducing structural integrity
Solution Approach 1:
The transmission medium serves as a mediator that transfers metal droplets without allowing direct impact between the flying plate and substrate. This maintains structural integrity by preventing local connections while preserving coating efficiency through the carried droplets.
3Manufacturing precision
If metal droplets are generated using pulse power supply with electric spark or arc, then the amorphous structure is enhanced, but the process complexity increases
Solution Approach 1:
The patent utilizes phase transitions through pulse power supply to generate metal droplets with specific amorphous structures. The electric spark or arc creates controlled thermal conditions that induce phase transitions in the metal material, achieving high-quality amorphous coatings.
