Tire Fire Extinguishing Injectors for Localized Vehicle Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fire extinguishing systems for vehicles are ineffective in covering all four tire regions, leading to inefficient and costly operations, as they require a single nitrogen tank and cylinder, which results in degraded injection pressure and excessive chemical distribution when trying to extinguish fires in multiple regions simultaneously.
Innovation Solution
A fire extinguishing system with multiple injectors and detection lines installed in each tire region, allowing for independent operation and precise injection of fire extinguishing chemicals only to the affected area, eliminating the need for lengthy injection lines and centralized systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single centralized fire extinguishing system with one nitrogen tank and one cylinder is used to cover all four tire regions, then the system structure is simple and cost is reduced, but the injection pressure is degraded and fire extinguishing effectiveness is insufficient
Solution Approach 1:
The patent divides the vehicle into four tire regions (front left, front right, rear left, rear right) and installs independent fire extinguishing injectors in each region. Each injector is connected to its own detection line, creating four independent fire extinguishing units. This segmentation allows each region to be protected independently with sufficient injection pressure, resolving the contradiction between system simplicity and fire extinguishing effectiveness.
2Ease of operation
If a single centralized system injects fire extinguishing chemical to all four tire regions simultaneously, then the system operates uniformly, but the chemical distribution becomes excessive and costly
Solution Approach 1:
The patent enables localized fire extinguishing by connecting each injector to its own detection line. When fire is detected in a specific tire region, only the injector in that region activates and releases fire extinguishing chemical locally. This prevents excessive chemical distribution to all regions and reduces chemical consumption, while maintaining ease of operation through automatic detection and response.
3Device complexity
If injection lines are extended to reach all four tire regions from a centralized location, then the system can be simplified, but the injection pressure becomes insufficient
Solution Approach 1:
The patent places nitrogen tanks and fire extinguishing chemical cylinders close to each tire region, eliminating the need for long injection lines. Each injector receives high-pressure nitrogen and fire extinguishing chemical from its own local tank, ensuring sufficient injection pressure is maintained without requiring complex long-distance piping systems.
4Reliability
If multiple independent injectors and detection lines are installed in each tire region, then fire extinguishing precision and effectiveness are improved, but the device complexity and cost increase
Solution Approach 1:
The patent uses identical fire extinguishing injector units in all four tire regions, each with the same structure comprising a nitrogen tank, fire extinguishing chemical cylinder, detection line, and injector. This standardized multi-functional design allows the same component to serve multiple locations, improving fire extinguishing precision while controlling complexity through component standardization and reusability.
