Solution Overview
Problem
Current fire protection systems are either expensive, difficult to modify, or ineffective in rapidly responding to changing risk environments, particularly in residential and cultural heritage settings, often causing significant damage and posing safety risks due to their reliance on large water flows or oxygen reduction methods.
Innovation Solution
A portable, modular fire protection system utilizing a mist-spraying technique with pressurized nozzles capable of reaching 100-150 bar, integrated with a control system and sensor network for active detection and adaptive response, minimizing damage and optimizing extinguishing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fire protection systems use large water flows, then fire suppression capability is improved, but secondary damage and cleaning costs increase
Solution Approach 1:
The patent changes the physical parameters of water delivery by transitioning from low-pressure large-flow delivery to high-pressure (100-150 bar) mist delivery. This parameter change allows the same fire suppression function to be achieved with dramatically reduced water consumption, eliminating secondary damage while maintaining reliability
Solution Approach 2:
The patent utilizes phase transition by converting liquid water into fine mist droplets through high-pressure nozzle atomization. This phase change from bulk liquid to dispersed droplets increases the surface area for heat absorption, improving fire suppression efficiency while reducing the total volume of water needed
2Reliability
If fixed fire protection installations are used, then fire suppression coverage is improved, but adaptability to changing risk environments deteriorates
Solution Approach 1:
The patent transforms the static fixed installation into a dynamic portable system that can be moved and repositioned according to changing risk environments. The modular design with movable components enables the system to adapt to different locations and configurations while maintaining effective fire suppression coverage
Solution Approach 2:
The patent divides the fire protection system into modular segments including separate extinguishing medium containers, pressurizing systems, and nozzle assemblies. This segmentation allows flexible reconfiguration and adaptation to different risk environments while maintaining comprehensive fire suppression capability
3Object-generated harmful factors
If inert gas is used as extinguishing medium, then water damage is reduced, but oxygen reduction poses safety risks in inhabited premises
Solution Approach 1:
The patent converts the potential harm of high-pressure water delivery into a benefit by using the high pressure to create fine mist droplets. This transforms the harmful large-volume water flow that causes damage into a beneficial low-volume mist that suppresses fire effectively while minimizing water damage
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 system provides effective fire suppression with reduced water usage, minimal secondary damage, and adaptability to changing risk environments, enhancing safety and reducing installation costs, particularly in high-risk areas like residential settings for the elderly and cultural heritage sites.
Implementation Method 1
at least one pressurizing system for pressurizing the liquid extinguishing medium
Implementation Method 2
spraying out the extinguishing medium liquid at such a high pressure through a mist-spraying nozzle that the mist is created
Implementation Method 3
cooling of seats of fire, where the mist absorbs large amounts of heat when it is heated up and changes from liquid (water) to gas (steam)
Implementation Method 4
prevention of heat radiation as the mist effectively absorbs IR-radiation
Implementation Method 5
displacement of oxygen when the mist changes from liquid to gas
