Solution Overview

Problem

Conventional snowmaking equipment lacks a efficient and integrated system for safely providing pressurized water and compressed air to snowmaking guns, leading to operational inefficiencies and increased costs.

Innovation Solution

A dual auto hydrant system that selectively controls the delivery of compressed air and pressurized water to snowmaking guns, allowing for controlled charging and discharging, featuring a piston mechanism with seals to manage independent air and water channels, and includes a water pipeline tap to prevent freezing and a moisture separating filter to ensure dry compressed air.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional separate water and air supply systems are used for snowmaking guns, then the equipment can operate with basic functionality, but the system complexity increases and operational efficiency decreases

Engineering Contradiction:
Improvesnowmaking operational efficiencyVSAvoidwater and air supply system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines separate water supply and compressed air supply systems into a single integrated hydrant unit. The hydrant contains both a water valve and an air valve within one housing, allowing operators to control both fluids through a single device rather than managing separate supply systems, thereby reducing overall system complexity while maintaining full functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The hydrant is designed as a multi-functional device that simultaneously handles water supply, air supply, and drainage functions. The single hydrant unit performs multiple operations that would otherwise require separate equipment, improving operational efficiency by consolidating controls and reducing the number of components needed.

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

2Productivity

If pressurized water is continuously supplied to snowmaking guns, then snowmaking operations can proceed without interruption, but water freezing in cold conditions increases maintenance requirements

Engineering Contradiction:
Improvecontinuous snowmaking operationVSAvoidwater freezing in supply lines
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The hydrant includes a drainage valve that allows operators to drain water from the supply lines before temperatures drop to freezing levels. This preliminary draining action prevents water from freezing in the lines during cold conditions, protecting the system from damage while allowing operations to resume quickly when conditions improve.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system transitions from static continuous water supply to dynamic controlled supply with drainage capability. Operators can adjust the water supply status based on environmental conditions, switching between supply and drainage modes to prevent freezing while maintaining operational flexibility.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If compressed air and water are supplied through separate systems, then each fluid can be controlled independently, but the number of valves and control points increases

Engineering Contradiction:
Improvefluid control simplicityVSAvoidnumber of valves and control points
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent integrates water valve and air valve controls within a single hydrant housing, reducing the number of separate control points from multiple distributed valves to one consolidated unit. This merging maintains independent control capability while simplifying the operational interface and reducing the total number of components.

Inventive Principle:
Principle #5Merging (Combining)

4Productivity

If moisture is present in compressed air supply, then the air can be used for snowmaking, but equipment reliability decreases due to potential freezing and corrosion

Engineering Contradiction:
Improvesnowmaking capabilityVSAvoidequipment durability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system includes a drainage mechanism that extracts and removes moisture from the compressed air supply line. By taking out the harmful moisture component before it reaches the snowmaking gun, the system maintains snowmaking capability while preventing the reliability issues that would result from moisture accumulation, such as freezing and corrosion.

Inventive Principle:
Principle #2Taking out (Extraction)
