Solid Aerosol Detonator with Embedded Hot Wire
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solid aerosol fire extinguishing apparatuses face issues with irregular combustion due to changes in physical properties and temperature over time, inadequate heating leading to incomplete combustion of the fire extinguishing agent, and the risk of damaging circuit boards or wires from high-temperature gases, especially when the heating means is externally coupled and prone to detachment.
Innovation Solution
A solid aerosol detonator is designed with a heat-generating unit and power supply within the apparatus, using a hot wire or resistant to provide consistent heating, a sealed member to contain and direct the fire extinguishing gas, and a second fire extinguishing agent to ensure complete combustion and prevent external impact damage, all while maintaining the heating unit inside the apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external heating means is coupled to the outside of the fire extinguishing apparatus, then heating can be provided to the solid aerosol, but the heating means may be detached due to small impact
Solution Approach 1:
The heating means is merged with the solid aerosol fire extinguishing agent into a single integrated unit. The hot wire is embedded within the fire extinguishing agent, eliminating the need for separate external coupling structures and ensuring the heating function remains reliably attached during impact events.
2Reliability
If electronic match is used to generate explosion, then ignition can be achieved, but combustion operation becomes irregular due to physical property changes over time
Solution Approach 1:
The electronic match and explosion-based ignition system are completely removed from the apparatus. Instead, a simple resistive heating element (hot wire) is used to provide steady thermal energy to the fire extinguishing agent, eliminating the irregular combustion caused by explosive ignition and physical property changes over time.
3Reliability
If heating temperature is insufficient, then safety is improved, but the internal solid aerosol is not perfectly combusted
Solution Approach 1:
The heating parameters are optimized by selecting appropriate resistive heating material and controlling the current flow to achieve the precise temperature range required for complete combustion of the solid aerosol fire extinguishing agent, ensuring both safety and combustion effectiveness.
4Productivity
If high temperature fire extinguishing gas is generated, then fire extinguishing power is improved, but circuit board or electric wire may be melted
Solution Approach 1:
The internal space is segmented into distinct functional zones: the heating/combustion chamber where high temperature occurs, and the component housing area where electronic components are located. This spatial separation allows high-temperature fire extinguishing gas to be generated effectively while protecting sensitive electronic components from thermal damage.

Function Achieved in This Case
This configuration ensures stable combustion of the solid aerosol, generates sufficient fire extinguishing gas, and protects internal components from heat damage, providing effective fire suppression without external ignition agents and maintaining apparatus integrity.
Implementation Method 1
a heat-generating unit connected to the power supply unit, upward protruded from the second plate through the first through hole and second through hole, supplied with power from the power supply unit, and heated at a specific temperature
Implementation Method 2
a first fire extinguishing agent configured to surround the outer circumferential surface of the heat-generating unit in such a way as to impregnate a specific portion of the heat-generating unit and detonated at an ignition point or more to generate a fire extinguishing gas
Implementation Method 3
The sprayed fire extinguishing component is applied to a place where a fire must be extinguished, and extinguishes the fire by blocking a material that causes the fire

AI summary
Disclosed herein is a solid aerosol detonator capable of generating a fire extinguishing gas by vaporizing an internal solid fire extinguishing agent in order to extinguish a fire which may be generated in a place to live or an industrial place and a fire extinguishing apparatus using the same. The solid aerosol detonator and the fire extinguishing apparatus using the same can be detonated using only a fire extinguishing agent of a solid form without using an electronic match or an ignition agent, that is, a material coated on an electrical percussion. Accordingly, the combustion action of a solid aerosol can be stably generated because the solid aerosol detonator and the fire extinguishing apparatus using the same are not sensitive to a change in the physical properties and a change in the temperature even after a lapse of a specific time.
