Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional fan guns with turbines are used to produce artificial snow, then snow production is achieved, but high ventilation power (12-20 KW) is required leading to increased energy consumption and cost
Solution Approach 1:
The invention divides the single turbulent mixing process into two distinct stages: first, a central jet projects water into ambient air to form fine droplets; second, a peripheral jet introduces nucleation particles (ice crystals) to promote freezing. This segmentation allows each stage to be optimized independently, reducing the total energy required compared to conventional single-stage turbulent mixing
Solution Approach 2:
The central jet performs preliminary atomization of water into fine droplets before the nucleation stage. By pre-forming the water droplets in a controlled manner with lower energy input, the subsequent nucleation process requires less ventilation power to complete snow formation, whereas conventional systems attempt all mixing and nucleation simultaneously at high energy cost
2Stability of the object's composition
If high ventilation power is used in conventional snow guns, then water and air mixing is achieved, but structural costs and energy consumption increase
Solution Approach 1:
The invention employs pneumatic principles by using pressurized air in the peripheral jet to deliver nucleation particles, and hydraulic principles through the controlled projection of water in the central jet. This combination allows precise control of the air-water-nucleation mixture formation without requiring high-power turbulent mixing, simplifying the overall equipment structure while maintaining mixture quality
Solution Approach 2:
The invention changes the operational parameters from high-power turbulent mixing to low-power controlled projection with sequential stage activation. By adjusting the timing and intensity of the central and peripheral jets independently, optimal snow production is achieved with reduced power consumption and simpler equipment requirements

The device efficiently produces high-quality artificial snow with reduced ventilation power, achieving optimum efficiency and lower energy consumption compared to prior devices.
Implementation Method 1
nucleation means for the production of at least one nucleation jet intended to form ice crystals, to promote the production of artificial snow from the cooperation of the central and peripheral jets
Implementation Method 2
The structure of this device ensures protection of the central jet by the peripheral jet, and partly uses the energy of the water, so as to delay and optimize the mixing between, on the one hand, the air and water jets
