Compact Fire Extinguishing System for Electronics Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire extinguishing systems for electronics housings often lack a compact and easily exchangeable configuration, with essential components not readily available or arranged for quick installation, leading to inefficient fire suppression, especially in lower areas of control cabinets.
Innovation Solution
A self-contained fire extinguishing system with a rectangular extinguishing agent container that integrates all necessary components, including a level indicator, dispensing device, and triggering mechanism, designed for quick installation and operation, utilizing a compact, flat design with a maximum height of 45 mm, and featuring a nozzle that can be screwed directly into the container for efficient agent distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a complete fire extinguishing system is arranged in a frame-like rack in the upper part of the control cabinet, then the system can be installed as a plug-in unit, but a very specific space must be used and fires in the lower part cannot be detected and extinguished with a delay
Solution Approach 1:
The patent transitions from vertical arrangement (upper part only) to horizontal distribution (along the entire depth of the cabinet). By placing detection and extinguishing units at multiple depths including the lower part, the system achieves comprehensive coverage without time delay while maintaining quick installation capability through modular design.
2Device complexity
If the spray device and sensor are arranged in the upper part of the container, then the system can be installed as a compact unit, but fires in the lower part can be detected and extinguished with a delay
Solution Approach 1:
The patent divides the fire extinguishing system into multiple independent modules distributed along the cabinet depth. Each module contains its own sensor and spray device, enabling localized detection and response. This segmentation maintains system integration benefits while eliminating the reliability issue of single-point detection by providing multiple detection points throughout the cabinet space.
3Adaptability or versatility
If a swiveling extinguishing unit is used with hinge connection, then the unit can be removed from the cabinet, but the connections between swiveling part and permanently installed parts must be assembled in a complicated manner
Solution Approach 1:
The patent extracts the connection complexity from the swiveling mechanism by using simple, standardized connection elements that can be quickly assembled and disassembled. The connection system is designed to be independently replaceable without requiring complex assembly procedures, thus maintaining adaptability while simplifying manufacturing and installation.

AI summary
The invention relates to a fire extinguishing system for a housing, preferably an electronic housing, said system comprising an extinguishing agent container storing the extinguishing agent, an extinguishing agent dispensing device, and a triggering device. Said container (2) is flat, and electronic and/or mechanical means required for monitoring leakage and/or displaying the level, for triggering and for dispensing the extinguishing agent can be built into the extinguishing agent container.
