Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing alarm valve stations in fire extinguishing systems face high assembly and maintenance costs, along with an increased risk of leakage and functional impairment due to complex line arrangements for connecting delay tanks to multiple components.
Innovation Solution
The integration of a delay tank within the alarm valve station with multiple fluid inlets and outlets eliminates the need for external line arrangements, reducing assembly and maintenance efforts and the risk of leakage, while allowing for space-saving design and efficient fluid distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the delay tank is connected to multiple separate components via external line arrangements with fittings, then the alarm valve station can trigger fire alarms through multiple pressure sensors and alarm devices, but the assembly and maintenance costs increase and the risk of leakage increases
Solution Approach 1:
The patent merges multiple connection functions into the delay tank itself by integrating multiple fluid outlets directly on the tank body. This eliminates the need for external fittings and line arrangements, reducing assembly complexity and leakage risk while maintaining the capability to connect to multiple pressure sensors and alarm devices.
Solution Approach 2:
The delay tank is designed with multi-functionality by incorporating multiple fluid outlets that can simultaneously or selectively connect to different components (pressure sensors, alarm devices). This universal design allows a single component (the delay tank) to serve multiple connection purposes without requiring complex external line arrangements.
2Adaptability or versatility
If the delay tank is connected to multiple separate components via external line arrangements, then the alarm valve station can distribute extinguishing fluid pressure to multiple components, but the assembly effort and maintenance costs increase
Solution Approach 1:
The patent combines multiple fluid distribution functions into the delay tank by integrating multiple fluid outlets directly on the tank body. This eliminates the need for external fittings and complex line arrangements, significantly reducing assembly effort and maintenance costs while maintaining the capability to distribute extinguishing fluid pressure to multiple components.
Solution Approach 2:
The patent extracts the connection functions from external line arrangements and integrates them directly into the delay tank structure. By taking out the need for external fittings and connections, the design simplifies assembly and maintenance while preserving fluid distribution capability to multiple components.
3Adaptability or versatility
If external line arrangements with fittings are used to connect the delay tank to multiple components, then the alarm valve station can connect to various alarm devices and pressure sensors, but the risk of leakage and functional failure increases
Solution Approach 1:
The patent merges multiple connection functions into the delay tank by integrating multiple fluid outlets directly on the tank body. This eliminates external fittings and connection points, thereby eliminating potential leakage sources and reducing the risk of functional failure while maintaining the capability to connect to various alarm devices and pressure sensors.
Solution Approach 2:
The patent converts the potential harm of external fittings (leakage risk) into a benefit by integrating connections directly into the delay tank structure. This design choice eliminates the harmful leakage risk associated with external fittings while preserving the beneficial connection capability to multiple components.
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
This configuration significantly reduces assembly and maintenance costs, minimizes the risk of leakage, and optimizes space usage by integrating the delay tank within the alarm valve station, ensuring reliable and efficient fluid distribution for triggering fire alarms.
Implementation Method 1
a pressure builds up at the pressure sensor, which is evaluated as an event for the generation of an alarm signal when a sufficiently large quantity of extinguishing fluid flows into the alarm line or the delay tank
Implementation Method 2
the stub line is fluidly connected to a pressure sensor, which detects the pressure change in the stub line caused by the inflowing extinguishing fluid
Implementation Method 3
When a certain pressure difference is reached, the closing body, which is located in the alarm valve and is closed when the alarm valve is in the idle state, is opened
