Fire Safety Guide Plate for Wall Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sprinkler systems struggle to effectively cool walls with horizontal profiles, as water sprayed by the system flows horizontally along the profile and then drips down, failing to provide further cooling to the wall below, which can lead to inadequate fire suppression and potential deformation of metal walls.
Innovation Solution
A fire-fighting device featuring a guide plate with specific areas arranged above, below, and alongside a horizontal profile, guiding water back to the wall using a narrow gap, ensuring efficient surface moistening and cooling, with preferred embodiments using stainless steel materials and attachment methods that do not obstruct water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a horizontal profile is installed on the wall, then structural support and stability are improved, but water flow distribution is worsened as water flows horizontally along the profile and fails to cool the wall below
Solution Approach 1:
A baffle plate is introduced as an intermediary element between the horizontal profile and the wall. The baffle plate intercepts water flowing horizontally along the profile and redirects it back onto the wall surface, ensuring continuous cooling below the profile while maintaining the profile's structural support function
Solution Approach 2:
The baffle plate extends in the horizontal dimension from the wall surface, creating a three-dimensional water redistribution system. This allows the baffle to intercept water in one dimension (horizontal flow along profile) and redirect it in another dimension (back onto the wall surface below)
2Productivity
If the baffle is positioned close to the wall, then water guidance efficiency is improved, but water flow rate is worsened due to restricted flow
Solution Approach 1:
The baffle plate's position is optimized at a specific distance (1-20 mm) from the wall, balancing two competing parameters: close enough to effectively guide water back onto the wall, but far enough to maintain adequate water flow rate and prevent restriction
3Quantity of substance
If the baffle distance from the wall is increased, then water flow rate is improved, but water guidance efficiency is worsened as water cannot be effectively returned to the wall
Solution Approach 1:
The optimal baffle distance range of 1-20 mm is established as a parameter solution that balances water flow rate and guidance efficiency. This parameter range ensures the baffle is far enough not to restrict flow but close enough to effectively redirect water onto the wall surface
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 solution enables efficient water redistribution to the wall, enhancing fire suppression and preventing metal wall deformation by maintaining effective cooling, even in the presence of a horizontal profile, thereby ensuring safer and more reliable fire protection.
Implementation Method 1
the water would run down the wall to the profile. On the profile, the water would initially flow horizontally away from the wall. At the end of the profile, the water then flows down the profile, describing a parabolic path to a first approximation due to the flow velocity. Here, the water hits the second and third areas of the baffle and is thus guided back to the wall
Implementation Method 2
The baffle further has at least one fourth region in the at least one second region, wherein the baffle has a distance from the wall of 1 mm to 20 mm in the at least one fourth region. Due to the comparatively narrow gap of 1 mm to 20 mm, the water does not run further down through the air, but is guided back to the wall
Implementation Method 3
water is sprayed against the walls by the sprinkler system, for example, or against the ceiling in such a way that the water runs down the walls. The running water cools the walls
Implementation Method 4
The running water cools the walls and, by cooling the wall, prevents a fire from spreading from a room on the other side of the wall. In the case of metal walls, the cooling also ensures that the metal walls do not deform as much in the heat
