Fire Lance Anchoring Through Vehicle Panels for Safer Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire lances require manual handling by operators, exposing them to high safety risks during fire extinguishing operations, especially in vehicles with internal combustion engines and electric vehicles where the battery pack is on the roof, necessitating dangerous proximity to the fire.
Innovation Solution
An anchoring system for fire lances that includes a hooking device connectable to the lance and a through opening in the vehicle's vertical wall, allowing the lance to be securely anchored, reducing operator exposure time to flames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fire lance is designed to be manually held by the operator, then the lance can be easily handled and directed, but the operator's exposure time to flames and dangerous conditions increases significantly
Solution Approach 1:
The patent introduces an intermediary anchoring system consisting of a hooking device on the lance and a corresponding seat on the vehicle body. This intermediary mechanism allows the lance to be securely positioned without requiring the operator to manually hold it, thus resolving the contradiction between ease of handling and operator safety by transferring the holding function from the operator to the anchoring system.
2Productivity
If the operator must get close to the battery pack on the roof to spray it, then the fire extinguishing operation can be performed, but the operator's safety is compromised due to dangerous proximity to the fire
Solution Approach 1:
The anchoring system acts as an intermediary that secures the lance at an optimal position near the fire source without requiring the operator to be in close proximity. The hooking device and seat arrangement allow the lance to be anchored at various positions on the vehicle body, enabling effective fire suppression while maintaining operator safety distance.
3Ease of operation
If the lance is inserted through a pass-through opening in the engine compartment wall, then the lance can reach the fire source, but the operator still must manually hold the lance
Solution Approach 1:
The patent enhances the existing pass-through opening approach by introducing the anchoring system as an intermediary. The hooking device engages with the seat on the vehicle body, providing secure positioning of the lance through the opening without requiring manual holding, thus maintaining access to the fire source while improving operator safety.
