Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smoke eliminator devices are not easy to use, inefficient, and lack the ability to easily penetrate windows for effective smoke removal during firefighting.
Innovation Solution
A lightweight, elongated smoke eliminator device that connects to a standard fire hose, featuring a glass-breaking mechanism, cooling nozzle, and adjustable water spray for efficient smoke and heat removal, with optional extensions for upper floor access and a bend for direct window use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a smoke eliminator device is designed to be lightweight and simple, then ease of operation is improved, but the ability to penetrate windows and reach upper floors is worsened
Solution Approach 1:
The patent combines multiple functions into a single integrated device: the smoke elimination function (water spray creating suction), the glass-breaking function (sharp edge on distal end), and the window ledge engagement function (butt section with holding teeth). This merging allows the device to be operated as one unit while providing multiple capabilities, resolving the contradiction between simplicity and versatility.
Solution Approach 2:
The device is designed to perform multiple functions: removing smoke through water-induced suction, breaking glass with the distal end, and engaging window ledges with the butt section. This multi-functionality allows a single lightweight device to address various firefighting scenarios without requiring multiple separate tools, thereby improving adaptability while maintaining ease of operation.
2Ease of operation
If a smoke eliminator device is designed to be lightweight, then ease of operation is improved, but the ability to withstand extreme heat is worsened
Solution Approach 1:
The patent specifies that the elongated tube be made of heat-resistant material, changing the material parameter to withstand extreme temperatures while maintaining a lightweight design. This parameter change allows the device to be both light for easy handling and resistant to heat from fires, resolving the contradiction between weight and heat resistance.
3Device complexity
If existing smoke eliminator devices are used without glass-breaking capability, then device complexity is reduced, but the ability to access buildings through windows is worsened
Solution Approach 1:
The glass-breaking capability is integrated into the distal end of the smoke eliminator device itself, rather than being a separate tool. The sharp edge or protrusion on the distal end allows the device to break glass while maintaining its primary smoke elimination function, thereby combining simplicity with effective glass-breaking capability.
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 device effectively removes smoke and heat from buildings, allowing easier rescue and fire extinguishing, is lightweight and easy to use, and can be operated by a single person, while minimizing water damage and maintaining structural integrity.
Implementation Method 1
Water emitted from the distal end of the device creates a suction which pulls smoke out of the room or building
Implementation Method 2
A cooling nozzle allows for the extinguishing of fire by water spray

AI summary
A smoke eliminator device is provided. The smoke eliminator device is especially suitable for removing smoke from a room or building so as to allow a firefighter to more easily rescue individuals and extinguish fires. The device is a lightweight elongated tube which connects to a standard fire hose. Water emitted from the distal end of the device creates a suction which pulls smoke out of the room or building. A glass-breaking device is located near a distal end of the device to allow the device to easily penetrate a window wherein it may be effective. A cooling nozzle allows for the extinguishing of fire by water spray. An extension may be added to the device to allow the device to be utilized in the upper floor of a building. The device may further have a bend which allows a user to utilize the device directly below a window of an upper floor.
