Solution Overview

Problem

Conventional fire protection systems are costly and often insufficient for private residences, particularly those with vulnerable occupants, as they rely on smoke detectors and handheld extinguishers that may not provide timely protection or sufficient access to extinguishing agents.

Innovation Solution

A portable fire protection system with a self-contained water supply and low-pressure pump, actuated by a remote wireless detector, featuring a pop-up sprinkler head that disperses water or extinguishing agent in a predetermined pattern, powered by an electrical storage battery with recharge capability, and designed for compact, unobtrusive placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional fire protection systems are installed, then fire suppression capability is provided, but cost is high and accessibility is poor

Engineering Contradiction:

Improvefire suppression capabilityVSAvoidaccessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system automatically detects smoke or fire conditions and activates the pump and sprinkler head without requiring manual operation. The wireless receiver detects signals from remote detectors and automatically triggers the fire suppression function, eliminating the need for occupants to manually activate the system during an emergency.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operation with automated electronic control. Wireless detectors and receivers eliminate the need for physical interaction with the system, while the electric pump replaces manual effort required to operate traditional fire extinguishing devices.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If handheld fire extinguishers are placed throughout the residence, then fire suppression capability is improved, but device complexity and cost increase

Engineering Contradiction:

Improvefire suppression capabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the detection function (wireless smoke detectors) with the suppression function (pump and sprinkler head) into a single integrated system. This consolidation provides comprehensive fire protection throughout the residence without requiring multiple separate devices to be strategically placed.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single automated system serves multiple functions: detection via wireless detectors, signal reception and processing, water pumping, and spray distribution. This multi-functional approach replaces the need for multiple specialized devices while maintaining comprehensive coverage.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If a compact portable system is designed, then ease of placement and unobtrusive appearance is achieved, but fire suppression coverage may be limited

Engineering Contradiction:

Improveplacement flexibilityVSAvoidfire suppression coverage

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The sprinkler head transitions from a retracted state to an extended operational state when activated. This dynamic movement allows the sprinkler head to reach its full spray coverage potential only when needed, maintaining a compact profile during normal conditions while ensuring adequate coverage during fire events.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system uses a pump to generate water pressure and flow, enabling the sprinkler head to deliver effective fire suppression coverage. The hydraulic system ensures sufficient water delivery pressure and volume to maintain adequate fire suppression capability despite the compact system size.

Inventive Principle:

Principle #29Pneumatics and hydraulics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The system provides effective fire suppression with a compact, user-friendly design that can be discreetly integrated into residential environments, ensuring timely and thorough extinguishing of fires, even in the presence of vulnerable individuals.

Implementation Method 1

The relatively low pressure of the pump and sprinkler head combination results in an array of variably sized water droplets

Methodology Applied

Scientific EffectPressure reduction: Pressure Drop

Implementation Method 2

larger droplets removing heat and drowning the fire and smaller droplets serving to cool the air

Methodology Applied

Scientific EffectEvaporative cooling: Evaporative Cooler

AI summary

The portable fire protection system comprises a self-contained apparatus including a quantity of fire extinguishing agent, a pump, a pop-up sprinkler head, a power supply, and a receiver. A remotely located smoke and fire detector communicates wirelessly with the receiver to actuate the apparatus in the event that smoke and/or fire is detected. The extinguishing agent is dispensed from the tank by the pump and the pop-up sprinkler head, with the head automatically deploying when water pressure is provided thereto by the pump. The low pressure sprinkler head dispenses a wide array of various sizes of droplets when the system is activated.
