Multi-Cartridge Fire Extinguisher Bracket Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixed fire extinguishing apparatuses have limited fire extinguishing ability due to the use of single cartridges and require complex and costly silica gel fixation methods, which are inconvenient and inefficient, leading to incomplete fire suppression in small spaces.
Innovation Solution
A fixed fire extinguishing apparatus with multiple cartridges that can be activated simultaneously, using a bracket and fixing device with a bolt, nut, and rotation-stopping mechanism to secure the cartridges, eliminating the need for silica gel and enhancing fire suppression by deflecting and filtering the aerosol gas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single cartridge is used in the housing, then the apparatus occupies less space, but the fire extinguishing ability is insufficient and dead angles remain
Solution Approach 1:
The housing is divided into multiple compartments, each accommodating a separate cartridge. This segmentation allows multiple fire extinguishing agents to be positioned at different locations within the housing, enabling comprehensive coverage of the protected space while maintaining a compact overall structure.
2Reliability
If silica gel is used to fix the cartridge, then the cartridge is secured in the housing, but the production process becomes complex and requires large working sites
Solution Approach 1:
The complex silica gel fixation process is extracted and replaced with a simple mechanical bracket structure. The bracket directly secures the cartridge in the housing through physical support, eliminating the need for chemical fixation materials and complex production processes while maintaining reliable cartridge positioning.
3Reliability
If silica gel is used to fix the cartridge, then the cartridge is secured, but the production cost increases and efficiency decreases
Solution Approach 1:
The time-consuming silica gel standing process (7-8 hours) is completely removed from the production workflow. The mechanical bracket allows for immediate cartridge installation and fixation without waiting for material solidification, dramatically improving production efficiency and reducing costs.
4Quantity of substance
If multiple cartridges are activated simultaneously, then complete fire extinguishment is achieved, but the control system becomes more complex
Solution Approach 1:
Multiple cartridges are integrated into a single housing with a unified activation controller. The controller simultaneously activates all cartridges through a coordinated mechanism, achieving complete fire extinguishment coverage while maintaining simple and unified control without requiring separate control systems for each cartridge.
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 apparatus provides enhanced fire protection with multiple cartridges, improved assembly efficiency, reduced production costs, and effective fire suppression with deflected and filtered aerosol gas, ensuring complete fire extinguishment in small spaces.
Implementation Method 1
an agent of the cartridge is ignited by an activation controller to burn to release a hot aerosol fire extinguishing gas
Implementation Method 2
a hot aerosol sprayed by the cartridge be deflected and sprayed from the spraying window
Implementation Method 3
residues generated after combustion of an agent are intercepted by being filtered by the filter net

AI summary
A fixed fire extinguishing apparatus, comprising a housing (2), a cartridge (1) and an activation controller connected to the cartridge (1), wherein the cartridge (1) is numbered at least two and arrayed in the housing (2). A plurality of cartridges (1) can be simultaneously activated via one activation controller (5), thus greatly enhancing the fire extinguishing performance of the fire extinguishing apparatus. In addition, the fixed fire extinguishing apparatus has a small overall size thus occupies less space.
