Solution Overview

Problem

Conventional fire suppression systems face challenges in effectively distributing fire suppressant agents over a wide area, often requiring multiple sprinklers to achieve adequate coverage, which can be costly and inefficient.

Innovation Solution

The design incorporates a sprinkler system with a conical member and deflector featuring multiple tines that rotate to distribute fire suppressant agents radially, increasing the coverage area while allowing for adjustable tine angles and slots to optimize spread and foam quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If conventional sprinklers are used to distribute fire suppressant agents, then the system is simple in structure, but the coverage area is limited and multiple sprinklers are required

Engineering Contradiction:
Improvecoverage areaVSAvoidsprinkler structure
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The deflector is designed to rotate about the longitudinal axis when fire suppressant agent flows through it, transforming from a static component to a dynamic one. This rotation enables the deflector to distribute the suppressant agent over a wider radial area, significantly increasing the coverage area without requiring multiple sprinklers. The dynamic motion is achieved through the interaction between the flowing suppressant agent and the deflector vanes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention transitions the distribution pattern from a conventional limited directional spray to a three-dimensional radial distribution. The rotating deflector with multiple angled vanes projects the fire suppressant agent in multiple directions simultaneously, creating a volumetric coverage pattern that expands the effective service area in horizontal, vertical, and radial dimensions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If multiple sprinklers are installed to achieve adequate coverage, then the coverage area is sufficient, but the system cost increases

Engineering Contradiction:
Improvecoverage areaVSAvoidnumber of sprinklers
Core Design Contradiction:
Area of stationary objectVSQuantity of substance

Solution Approach 1:

The enhanced sprinkler design with rotating deflector performs multiple functions: it distributes fire suppressant agent radially, rotates to expand coverage dynamically, and maintains adequate spray pressure throughout the service area. This multi-functional capability allows a single sprinkler to replace what would traditionally require multiple conventional sprinklers, reducing the total quantity needed while achieving sufficient coverage.

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

3Area of stationary object

If the deflector rotates to distribute fire suppressant agent radially, then the spread and service area are enhanced, but the device complexity increases

Engineering Contradiction:
Improveservice areaVSAvoiddeflector mechanism
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The deflector rotation mechanism is self-driven by the kinetic energy of the flowing fire suppressant agent itself. The agent's flow through the deflector vanes creates the rotational motion automatically, eliminating the need for external motors, power sources, or complex control systems. The system uses its own operating fluid to power the enhancement mechanism, minimizing additional complexity while achieving expanded service area.

Inventive Principle:
Principle #25Self-service

AI summary

A sprinkler includes an inlet aperture, an outlet aperture, a body, a conical member, and a deflector. The inlet aperture receives fire suppressant agent at an inlet end of the sprinkler and the outlet aperture is at an outlet end of the sprinkler. The body extends along a longitudinal axis and includes an inner volume forming a fluid flow path between the inlet end and the outlet end of the sprinkler. The conical member is positioned at the outlet end of the sprinkler directs the fire suppressant agent outwards. The deflector receives fire suppressant agent from the conical member and distributes the fire suppressant agent about a service area. The deflector includes multiple tines, which each extend along a corresponding radial axis that is substantially perpendicular with the longitudinal axis. Each tine is offset by an angular amount about the corresponding radial axis.
