Cobra Fire Extinguisher Mount with Rotating Nozzle for Automatic Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fire extinguishers require manual operation, making them ineffective for fires occurring when no one is present and posing a risk of injury, and existing automatic solutions are not compatible with existing installations or offer limited discharge range.
Innovation Solution
A cobra automatic fire extinguishing device that mounts on a fire extinguisher, featuring a rotating nozzle and motorized components to automatically aim and spray extinguishing liquid over a wide range, including a safety pin removal mechanism and integrated fire detection using cameras and sensors, allowing for both automatic and manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual operation is used, then the fire extinguisher can be operated, but it cannot be used when no one is present and poses injury risk
Solution Approach 1:
The fire extinguisher is equipped with a fire detection sensor that automatically detects fires and triggers the discharge mechanism without human intervention. The system serves itself by detecting the fire condition and automatically activating the extinguishing function, eliminating the need for manual operation while maintaining effectiveness.
Solution Approach 2:
The manual mechanical operation (pulling pin, pressing lever) is replaced with an automated control system that uses fire detection sensors and electronic control circuits to trigger the discharge mechanism automatically, substituting human mechanical actions with sensor-based automation.
2Extent of automation
If existing automatic operation device is used, then automatic lever operation is achieved, but safety pin removal and hose lifting functions are missing
Solution Approach 1:
The device integrates multiple functions (fire detection, safety pin removal, hose lifting, lever operation) into a single comprehensive system that can be applied to existing fire extinguishers. This multi-functional design makes the device universally compatible while providing complete automatic operation capability.
Solution Approach 2:
The automatic operation device is divided into separate functional modules: fire detection module, safety pin removal module, hose lifting module, and lever operation module. Each module performs a specific function, allowing the system to be comprehensively compatible with existing fire extinguishers while providing complete automation.
3Device complexity
If fixed position spraying is used, then the structure is simple, but the discharge range is limited
Solution Approach 1:
The nozzle is made movable rather than fixed, allowing it to rotate and adjust its spraying direction dynamically. This enables the fire extinguisher to target fires in different directions and positions, significantly expanding the discharge range while maintaining relatively simple structural design.
Solution Approach 2:
The nozzle positioning system adds rotational movement capability, transforming the spraying direction from a single fixed direction to multiple directions across different angles and positions, effectively expanding the coverage area without proportionally increasing structural complexity.

AI summary
The present invention relates to a cobra automatic fire extinguishing device capable of loading a fire extinguisher. The cobra automatic fire extinguishing device can automatically spray extinguishing fluid to a location of a fire by mounting a fire extinguisher inside, detecting the location of the fire, and directing the nozzle to the location of the fire. In addition, the cobra automatic fire extinguishing device can be installed economically since it does not require additional cost and time for manufacturing a separate, dedicated fire extinguisher and certification procedure. Furthermore, the cobra automatic fire extinguishing device can effectively extinguish a fire by precisely spraying the extinguishing liquid to the location of the fire, and can prevent conflagration by suppressing the initial fire.
