Motorized Drill Lance for Direct EV Battery Fire Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for extinguishing electric vehicle battery fires are inefficient and require large-scale water supplies, making them impractical for immediate response, and current technologies lack a proactive solution to prevent re-ignition.
Innovation Solution
A motorized drill lance apparatus that automatically drills a fire extinguishing hole in the electric vehicle battery using a motor-powered drill module and injects water to extinguish the fire directly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large amounts of water are continuously injected for a long period to extinguish EV battery fire, then the fire can be suppressed, but the response time is delayed and the operation becomes impractical
Solution Approach 1:
The apparatus performs preliminary action by automatically drilling a hole into the battery pack immediately upon detecting fire, creating a direct water injection path in advance. This eliminates the time-consuming manual positioning and setup required by conventional methods, enabling immediate and effective fire suppression from the outset.
Solution Approach 2:
The invention extracts the critical function of creating a water injection path from the complex conventional process (requiring crane lifting and water tank submersion) and implements it as a simple automated drilling operation. This extraction allows the system to achieve effective fire suppression without the time-consuming preparatory steps of traditional methods.
2Reliability
If conventional fire extinguishing methods are used without specialized equipment, then the system complexity remains low, but the fire extinguishing effectiveness is insufficient
Solution Approach 1:
The apparatus integrates multiple functions into a single device: the drilling unit creates injection paths, the water storage tank provides water supply, and the injection system delivers cooling water. This multi-functional integration achieves effective fire suppression without requiring multiple separate pieces of equipment, thereby limiting the increase in system complexity.
Solution Approach 2:
The system is designed to be self-sufficient with an integrated water storage tank and automated drilling mechanism. Once deployed, the apparatus autonomously drills holes and injects water without requiring external equipment like cranes or water tanks, achieving high fire extinguishing effectiveness while maintaining relatively simple operational procedures.
3Productivity
If manual positioning and setup are used, then the ease of operation is maintained, but the productivity and response speed are reduced
Solution Approach 1:
The invention replaces manual mechanical positioning and setup with an automated drilling mechanism powered by a motor. This mechanical substitution dramatically increases productivity by enabling immediate hole drilling upon deployment, while the automated nature of the system actually simplifies operation by eliminating the need for manual positioning and alignment.
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 apparatus effectively prevents thermal runaway and re-ignition by drilling a hole and injecting water directly into the battery, applicable even with low-pressure water supplies, and can be used with existing infrastructure.
Implementation Method 1
a motor 122 disposed on a side of the housing 121
Implementation Method 2
an elastic body 126 disposed below the hole cutter 125 and lifting the hole cutter 125 upward using elastic force
Implementation Method 3
when the hole cutter 125 is rotated by the power of the motor 122 while an upper side of the hole cutter 125 is in close contact with a bottom of the electric vehicle battery, a fire extinguishing hole for injecting the water may be drilled into the bottom of the electric vehicle battery
Implementation Method 4
injects water to swiftly extinguish the fire
Implementation Method 5
effectively prevents thermal runaway and re-ignition by drilling a hole and injecting water directly into the battery
