Solution Overview

Problem

Existing artificial snow sports environments, such as indoor slopes and resort snowmaking facilities, fail to provide an exciting and physically demanding experience for advanced skiers and snowboarders, as they are either weather-dependent or suited mainly for beginners and family groups.

Innovation Solution

A large, revolving cylindrical housing with an internally coated skiable surface of artificially created ice crystals, utilizing a network of heat conductive tubes and a refrigerant system to form and maintain the ice surface, combined with a water spray mechanism to generate fine ice particles, and optionally, a solid layer of artificial skiable material tiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If indoor slope facilities are used, then accessibility to skiing is improved for city dwellers, but the excitement and physical demand are reduced making them suitable mainly for beginners

Engineering Contradiction:
ImproveaccessibilityVSAvoidexcitement and physical demand
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The support surface is made movable by rotating the drum about its central longitudinal axis. This dynamic element creates variable friction conditions that can influence user movement, providing both accessibility for beginners and adjustable challenge for advanced users seeking excitement and physical demand

Inventive Principle:
Principle #15Dynamics

2Reliability

If resort snowmaking facilities are used, then skiing experience can be maintained at adequate skill level, but weather dependency and location requirements limit accessibility

Engineering Contradiction:
Improveskiing experience qualityVSAvoidaccessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces weather-dependent natural snowmaking with a controlled mechanical system. A drum with heat conductive tubes and refrigerant circulation creates artificial snow through phase change, eliminating atmospheric condition dependencies and enabling reliable skiing experience delivery at accessible urban locations

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If a drum rotatable about its central longitudinal axis is used, then movement of users can be influenced to create physical challenge, but the complexity of the apparatus increases

Engineering Contradiction:
Improvephysical challengeVSAvoidapparatus complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The drum structure serves multiple functions: it supports the skiable surface, provides the rotating mechanism for influencing user movement, and houses the heat conductive tubes for snowmaking. This multi-functionality reduces overall apparatus complexity while maintaining the ability to create physical challenge through variable rotation speeds and directions

Inventive Principle:
Principle #6Universality (Multi-functionality)
