Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional nozzle design is used to supply powdered material, then the apparatus structure is simple, but material diffusion and scattering occur reducing manufacturing precision
Solution Approach 1:
The patent replaces conventional mechanical powder supply mechanisms with a magnetic field-based system. A magnetic field generating section creates a magnetic field that causes powdered material to swirl and converge toward the nozzle opening, eliminating the need for complex mechanical feeding mechanisms while improving material supply accuracy and reducing scattering.
Solution Approach 2:
The patent changes the physical state and motion parameters of the powdered material by applying a magnetic field. The magnetic field alters the trajectory and distribution of powder particles, causing them to swirl and converge rather than diffuse, thereby improving manufacturing precision without increasing structural complexity.
2Manufacturing precision
If magnetic field is applied to reduce material scattering, then manufacturing precision is improved, but energy consumption increases
Solution Approach 1:
The magnetic field is applied selectively and locally only within the nozzle region where powder convergence is needed, rather than throughout the entire manufacturing chamber. This partial application of the magnetic field achieves the desired precision improvement while minimizing overall energy consumption.
