Solution Overview

Problem

Traditional steam generation systems for entertainment venues output excessive liquid condensate and chemical residues, leading to increased maintenance and costs due to the need for cleaning, which detracts from the desired immersive experience.

Innovation Solution

A steam effect nozzle with baffles and a sloped housing section that separates steam from liquid condensate, allowing the condensate to drain away while the steam is output, using a controlled pressure system to ensure minimal liquid emission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If traditional steam generation systems are used to output steam for show attractions, then the steam effect is produced, but excessive liquid condensate is output which increases maintenance and cleaning time

Engineering Contradiction:
Improvesteam outputVSAvoidliquid condensate
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

The nozzle is divided into separate functional sections: a steam outlet section with a nozzle outlet for steam discharge, and a condensate outlet section for liquid condensate removal. Baffles within the housing section further segment the flow path to separate steam from condensate, allowing each component to handle its designated substance efficiently

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention extracts and removes the harmful liquid condensate from the steam flow before discharge. The condensate outlet section specifically extracts liquid condensate from the mixed steam-liquid flow, preventing it from being output along with the steam and thereby reducing maintenance requirements

Inventive Principle:
Principle #2Taking out (Extraction)

2Quantity of substance

If traditional systems use chemicals other than water to generate vaporous fluid, then the desired effect is achieved, but chemical residue is left on surfaces increasing maintenance and cleaning costs

Engineering Contradiction:
Improvevaporous fluid outputVSAvoidchemical residue
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The invention changes the chemical composition parameter of the vaporous fluid from chemical-based synthetic steam to pure water-based steam. By using only water as the steam generation medium, the system eliminates chemical residues while maintaining the desired steam effect, thereby reducing maintenance and cleaning costs

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If steam and liquid condensate are not separated, then the system is simpler, but the desired steam effect is reduced and maintenance time increases

Engineering Contradiction:
Improvenozzle structureVSAvoidsteam effect quality
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The nozzle structure is segmented into distinct steam and condensate outlet sections with internal baffles to separate the two phases. This segmentation ensures that steam and liquid condensate follow different flow paths and are discharged separately, maintaining high-quality steam effect while managing the complexity through functional division

Inventive Principle:
Principle #1Segmentation

4Device complexity

If steam and liquid condensate are not separated, then device complexity is reduced, but maintenance and cleaning time increases

Engineering Contradiction:
Improvenozzle structureVSAvoidmaintenance and cleaning time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The condensate outlet section extracts and removes liquid condensate from the system separately from the steam discharge path. This extraction mechanism prevents liquid condensate from contaminating surfaces requiring maintenance, thereby significantly reducing cleaning time despite the added structural complexity of the dual-outlet design

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A steam effect nozzle includes a housing section configured to receive a fluid having a mixture of steam and liquid condensate and baffles disposed in the housing section. The baffles are configured to separate the steam of the fluid from the liquid condensate of the fluid, enable the steam to travel from a first end wall of the housing section to a second end wall of the housing section, and bias the liquid condensate of the fluid toward a sloped lower surface of the housing section, the sloped lower surface sloping downwardly from the second end wall toward the first end wall. The steam effect nozzle also includes a nozzle outlet adjacent to the second end wall of the housing section, where the nozzle outlet is configured to output the steam to an external environment.
