Fire Suppression Nozzle Spherical Dispersal via Segmented Apertures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray nozzles lack effective distribution of fluid for firefighting, as they do not efficiently disperse fluid in a spherical pattern, which limits their firefighting capability.
Innovation Solution
A cylindrical nozzle with a plurality of apertures arranged in central, forward, and rearward arrays, angled to expel fluid perpendicularly and rearwardly, creating a roughly spherical dispersal pattern and enhancing atomization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional spray nozzle design is used, then the structure is simple, but the fluid distribution effectiveness is poor
Solution Approach 1:
The nozzle body is segmented into multiple aperture arrays (central array, forward array, rearward array) with different orientations. Each array directs fluid at specific angles to achieve comprehensive spherical coverage, transforming a single-function nozzle into a multi-directional spray system that enhances firefighting effectiveness.
Solution Approach 2:
The patent transitions from conventional single-direction or limited-angle spray patterns to three-dimensional spherical dispersal. By incorporating apertures oriented in multiple spatial dimensions (central, forward, rearward arrays with various angles), the nozzle achieves volumetric fluid distribution rather than planar coverage, significantly improving fire suppression capability.
2Area of stationary object
If fluid is expelled in a single direction, then the nozzle structure is simple, but the dispersal coverage is limited
Solution Approach 1:
The aperture system is divided into distinct arrays (central array with perpendicular apertures, forward array with forwardly angled apertures, rearward array with rearwardly angled apertures). Each array segment contributes to a specific portion of the spherical coverage, and their combined effect achieves comprehensive 360-degree spray distribution.
Solution Approach 2:
The aperture arrays are asymmetrically arranged with different orientations and angles relative to the nozzle axis. The central array provides perpendicular spray, the forward array provides forwardly angled spray, and the rearward array provides rearwardly angled spray. This asymmetric configuration optimizes coverage in all directions while maintaining a relatively simple cylindrical nozzle body structure.
3Reliability
If fluid atomization is not enhanced, then the nozzle is easier to manufacture, but the firefighting effectiveness is reduced
Solution Approach 1:
The multiple aperture arrays create numerous small fluid streams that naturally enhance atomization through increased surface area and turbulence. The segmentation of the spray into multiple directional streams promotes better mixing with air and more effective breakdown of fluid into fine droplets, improving firefighting capability without requiring complex atomization mechanisms.
Solution Approach 2:
By directing fluid in multiple three-dimensional directions rather than a single plane, the patent creates cross-flow interactions between adjacent streams. This multi-dimensional arrangement promotes turbulent mixing and enhanced atomization as fluid streams intersect and break up, achieving effective droplet formation through geometric configuration rather than mechanical atomization devices.
