Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If artificial snow is produced from water using snow making apparatus, then the amount of snow is increased, but water and energy consumption is heavy and the process is costly
Solution Approach 1:
The patent creates artificial snow grains that copy the physical structure and magnetic properties of natural snowflakes. By using magnetized particles that aggregate and disperse like natural snow, the invention replicates natural snow's behavior without requiring water freezing processes, thereby reducing energy consumption while maintaining snow quantity
Solution Approach 2:
The patent changes the fundamental parameter from water-based snow production to magnetized particle aggregation. By controlling magnetic field parameters and particle properties rather than temperature and pressure parameters used in traditional snow making, the process eliminates heavy energy consumption associated with water freezing while producing sufficient artificial snow
2Quantity of substance
If artificial snow is produced from water using snow making apparatus, then the amount of snow is increased, but the process time is long and cost is high
Solution Approach 1:
The patent copies the essential aggregation behavior of natural snowflakes using magnetized particles. These particles naturally clump together under magnetic influence to form snow-like structures instantly, eliminating the time-consuming water freezing and compaction processes required by traditional snow making apparatus
Solution Approach 2:
The patent performs preliminary magnetization of particles before they are deployed as artificial snow. This pre-preparation allows the particles to immediately aggregate into snow-like formations upon contact with the magnetic field in the trail, eliminating the time required for on-site snow production and compaction
3Reliability
If organic material grains are used to produce artificial snow, then the similarity to natural snow is improved, but water consumption is heavy and the producing process is complex
Solution Approach 1:
The patent uses composite particles consisting of magnetized core materials coated with substances that simulate natural snow surface properties. This composite structure achieves high similarity to natural snow in terms of appearance and behavior while using simple magnetic aggregation processes rather than complex organic material processing
Solution Approach 2:
The patent replaces complex mechanical and chemical processes used in organic artificial snow production with a magnetic field-based system. The magnetized particles respond to magnetic fields to aggregate and disperse like natural snow, achieving high reliability without the complex producing processes associated with organic materials
4Adaptability or versatility
If dry skiing with solid lubricating agents is used, then the restrictions of environmental temperature and seasons are mitigated, but the skiing experience is different from natural snow and the production is complex
Solution Approach 1:
The patent copies the physical and magnetic properties of natural snowflakes to create artificial snow grains that authentically replicate natural snow's behavior. These magnetized particles aggregate, disperse, and interact with skis in ways that closely mimic natural snow, providing an authentic skiing experience while maintaining year-round availability through temperature independence
Solution Approach 2:
The patent changes the fundamental parameter from using solid lubricating agents to using magnetized particles. This parameter change enables the artificial snow to exhibit natural snow-like aggregation and dispersion behaviors while being independent of environmental temperature and seasonal conditions, thereby improving both skiing experience quality and availability

AI summary
Provided are artificial snow at a normal temperature, a method of manufacturing same and a trail made therefrom. The artificial snow at a normal temperature is used for skiing and is composed of grains of artificial snow at a normal temperature comprising magnetic solid grains. A manufacturing method comprises the following steps: (1) using a crushing apparatus to crush a magnetic material into solid grains; (2) using a mesh sieve at a certain particle size to sieve the solid grains; and (3) enabling the surface of the solid grains obtained after sieving to adhere to a layer of material capable of modifying surface performance. A trail comprises the artificial snow at a normal temperature. The artificial snow at a normal temperature can simulate the features of natural snow well, is simple to manufacture, convenient to use, simplifies the operation of creating a trail, and can replace natural snow on a large scale in order to create a trail, thereby enabling a substantial reduction in the restrictions of environmental temperature and seasons on skiing, lengthening the operating time of a ski resort, and significantly increasing the returns of the ski resort.
