Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire extinguishing systems with active intervention valves face issues such as mechanical failure, energy dependency, increased maintenance costs due to periodic testing, and inefficiency in extinguishing processes due to moving parts and auxiliary energy requirements.
Innovation Solution
The system employs rupture discs as intervention bodies, which burst to discharge extinguishing material automatically in response to pressure changes, eliminating the need for auxiliary energy and reducing the likelihood of mechanical failure, allowing for a simpler, low-maintenance extinguishing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If active intervention valves with moving parts are used to control extinguishing material discharge, then the system can be remotely controlled and automatically operated, but the valves may become faulty or jammed, reducing reliability
Solution Approach 1:
The invention extracts and eliminates the moving parts from the intervention valve system by replacing them with rupture discs. The rupture discs are simple pressure-sensitive membranes that burst when a predetermined pressure is reached, thereby controlling the discharge of extinguishing material without any mechanical moving parts that could fail or jam.
Solution Approach 2:
The rupture discs are designed as disposable, single-use components that are replaced after each operation. This approach ensures high reliability for each individual use, as the rupture disc is guaranteed to function correctly until it bursts, and can be easily replaced without complex maintenance procedures.
2Extent of automation
If active intervention valves are used with auxiliary energy sources, then remote control and automatic operation are enabled, but the system becomes dependent on external energy and requires periodic testing
Solution Approach 1:
The rupture disc system is self-actuating and does not require any external energy source. The rupture disc automatically bursts when the predetermined pressure is reached, either due to pressure increase from the storage body or pressure decrease in the reference pressure supply line. This eliminates the need for electrical power, pneumatic supplies, or other auxiliary energy sources.
Solution Approach 2:
The invention replaces the complex mechanical valve system with moving parts and actuators with a simple pressure-sensitive rupture disc system. The control function is achieved through pressure differential across the rupture disc rather than through mechanical actuation, thereby eliminating the need for auxiliary energy systems.
3Reliability
If periodic testing of intervention valves is performed to ensure operability, then reliability is maintained, but valuable extinguishing material is discharged and operation costs increase
Solution Approach 1:
The rupture discs are designed as inexpensive, disposable components that can be easily replaced. This allows the system to operate without periodic testing, as each rupture disc is guaranteed to function correctly until it bursts. The low cost and simplicity of replacement eliminates the need for costly periodic tests that would discharge valuable extinguishing material.
4Ease of operation
If active intervention valves are used, then controlled discharge of extinguishing material is achieved, but the valves require lubrication and maintenance, increasing operation and maintenance costs
Solution Approach 1:
The invention extracts and removes all moving parts from the discharge control system. The rupture disc system provides controlled discharge through a simple pressure-sensitive membrane that bursts at a predetermined pressure, eliminating the need for lubrication, adjustment, or maintenance of mechanical components.

Function Achieved in This Case
This solution enhances the reliability and cost-effectiveness of fire extinguishing systems by eliminating the need for auxiliary energy and reducing maintenance, ensuring consistent operation even during power outages or pneumatic network failures.
Implementation Method 1
using these rupture discs in a completely different way to that known a closed space maintaining a given pressure value is created in the pipe serving for discharging the extinguishing material that loses the pressure set in it when an undesired event occurs, or on the contrary, the pressure drastically increases, and at this time the appropriately dimensioned rupture discs burst
