Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fire extinguishing systems for vehicles are ineffective in responding to fires across multiple tire areas due to limitations in spray pressure and coverage, leading to inefficient and costly fire suppression, especially in larger vehicles like buses and trucks.
Innovation Solution
A fire extinguishing system with fire detection sensors and sprayers installed at each tire area, using a pressure generator with a spring mechanism and RF communication to selectively spray fire extinguishing agent only at the tire with a detected fire, ensuring effective and precise extinguishing without the need for centralized nitrogen tanks and lengthy hoses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a centralized nitrogen tank and hose system is used to supply fire extinguishing agent to multiple tire areas, then the system can cover all tire areas, but the spray pressure decreases and the system becomes complex and costly
Solution Approach 1:
The patent divides the fire extinguishing system into independent modular units, with each tire area having its own fire detection sensor and fire extinguishing agent sprayer. This segmentation eliminates the need for long hoses and centralized nitrogen tanks, maintaining high spray pressure at each location while covering all tire areas independently.
2Area of stationary object
If a centralized nitrogen tank and hose system is used to supply fire extinguishing agent to multiple tire areas, then the system can cover all tire areas, but the device complexity increases
Solution Approach 1:
The system is segmented into independent units at each tire location, each containing its own detection and extinguishing components. This eliminates complex centralized infrastructure including nitrogen tanks, high-pressure hoses, and centralized control systems, reducing overall device complexity while maintaining comprehensive coverage.
Solution Approach 2:
Each tire area is equipped with its own fire detection sensor and fire extinguishing agent sprayer, enabling autonomous detection and response. This self-service approach eliminates the need for centralized control systems and complex interconnections, significantly reducing device complexity.
3Area of stationary object
If a centralized nitrogen tank and hose system is used to supply fire extinguishing agent to multiple tire areas, then the system can cover all tire areas, but the cost increases
Solution Approach 1:
The patent implements segmented independent units at each tire location rather than a centralized system. This eliminates expensive components such as high-pressure nitrogen tanks, lengthy hoses, and complex centralized control systems, significantly reducing manufacturing costs while maintaining coverage of all tire areas through simple, modular units.
4Area of stationary object
If fire extinguishing agent is sprayed at all tire areas simultaneously, then all areas are covered, but the response efficiency decreases and unnecessary agent is consumed
Solution Approach 1:
The system segments the fire extinguishing response by tire location, with each area having its own detection sensor and sprayer. This enables selective activation of only the affected tire area rather than simultaneous spraying at all locations, improving response efficiency and reducing unnecessary fire extinguishing agent consumption.
Solution Approach 2:
Each tire area has its own fire detection sensor that provides localized feedback about fire conditions. The fire control unit receives signals from specific sensors and activates only the corresponding sprayer, enabling precise, demand-based response that improves efficiency and avoids unnecessary agent consumption.
5Measurement precision
If fire detection sensors and sprayers are installed at each tire area, then selective spraying is enabled, but the device complexity increases
Solution Approach 1:
Each tire area is equipped with its own fire detection sensor and fire extinguishing agent sprayer that operate autonomously. When a sensor detects fire at a specific location, it triggers only the corresponding sprayer without requiring complex centralized control logic, achieving high detection precision while keeping the system simple and modular.
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, rapid, and precise fire extinguishing for all tire areas by selectively spraying the extinguishing agent only at the fire location, improving response efficiency and reducing costs compared to conventional systems.
Implementation Method 1
Each of the fire extinguishing agent sprayers (110) is provided with a pressure generator (120) which operates to generate spray pressure

AI summary
A fire extinguishing system for a tire of a vehicle is capable of effectively responding to a fire in all tire areas of the vehicle, and of spraying fire extinguishing agent selectively only for the tire having the fire, thereby performing effective fire extinguishing. The fire extinguishing system includes: a fire detection sensor configured to detect the fire in the tire of the vehicle; a fire control unit configured to receive a signal output from the fire detection sensor and to output a control signal for spraying fire extinguishing agent when the fire control unit determines a fire occurrence; and a plurality of fire extinguishing agent sprayers configured to spray the fire extinguishing agent toward the tire having the fire according to the control signal output by the fire control unit, in a state of being filled with the fire extinguishing agent therein.
