Solution Overview

Problem

Existing snow cannon devices face issues with heat generation from air compressors disrupting the thermal equilibrium of air flow and lack efficient heat control, leading to suboptimal snowflake formation and increased electricity consumption.

Innovation Solution

A snow cannon design where the air compressor is driven by the motor of the fan, with the compressor located inside the tubular member and connected via a rotary shaft, and features a container with through openings or holes to direct air flow for cooling, reducing overheating and thermal disturbances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If the air compressor is located inside the tubular member and driven by the fan motor, then electricity consumption is optimized and device complexity is reduced, but the compressor generates heat that disrupts the thermal equilibrium of the air flow

Engineering Contradiction:
Improveelectricity consumptionVSAvoidthermal equilibrium of air flow
Core Design Contradiction:
Use of energy by moving objectVSTemperature

Solution Approach 1:

The harmful heat generated by the compressor is extracted and removed from the air flow path. The compressor is positioned such that its discharge outlet is separated from the air flow, and the discharge duct directs compressed air away from the thermal field, preventing heat transfer to the air flow while maintaining the single-motor configuration

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A discharge duct acts as an intermediary element between the compressor and the air flow. This duct provides a controlled path for compressed air discharge that isolates the heat source from the air flow, allowing the compressor to remain inside the tubular member while preventing thermal interference

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the compressor is located inside the tubular member alongside the fan motor, then device complexity is reduced, but it is not possible to control the emission of heat inside the tubular member

Engineering Contradiction:
Improvenumber of motorsVSAvoidcontrol of heat emission
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The internal space of the tubular member is segmented into distinct functional zones: a first portion for the air flow path and a second portion for the compressor and discharge duct. This spatial segmentation allows the single compressor to be housed within the tubular member while controlling its thermal impact through zoned separation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The discharge duct serves as a controlled intermediary that manages heat emission. By providing a dedicated discharge path, the system controls where and how heat is released inside the tubular member, preventing uncontrolled thermal distribution while maintaining structural integration

Inventive Principle:
Principle #24Intermediary (Mediator)
