Parking-Space Fire Blanket Deployment for EV Fire Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire protection devices for vehicles, particularly battery-operated vehicles, are cumbersome to deploy and often require significant manual effort, leading to delayed containment of fire spread.
Innovation Solution
A compact fire protection blanket is integrated into a housing mounted on a parking space, equipped with a pull-out device for automatic or manual deployment, ensuring complete coverage around the vehicle to isolate it from oxygen and insulate it from fire until professional assistance arrives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fire protection blanket is stored folded up in a transport box and manually positioned over a vehicle, then the blanket can provide fire protection, but the deployment requires considerable manual effort and valuable time is lost
Solution Approach 1:
The fire protection blanket is pre-positioned in a housing mounted on the parking space structure, ready for immediate deployment. The pull-out device is pre-configured to automatically deploy the blanket when triggered, eliminating the need for manual positioning efforts and reducing deployment time.
Solution Approach 2:
The system uses a pull-out device that can be manually or automatically activated to deploy the blanket without requiring persons to physically handle and position the heavy blanket. The device serves itself by converting simple pull motion into automatic blanket deployment over the vehicle.
2Reliability
If a fire protection blanket with high weight is used to ensure sufficient fire resistance, then the protection effectiveness is improved, but the handling difficulty increases
Solution Approach 1:
The pull-out device acts as an intermediary between the operator and the heavy fire protection blanket. Instead of directly handling the heavy blanket, the operator simply pulls the cord or activates the device, which then handles the heavy blanket deployment automatically.
Solution Approach 2:
The manual mechanical handling of the heavy blanket is replaced by a mechanical pull-out device system that uses a cord, reel, or automated mechanism to deploy the blanket, substituting the direct mechanical effort with a simplified activation mechanism.
3Device complexity
If a fire protection device is manually deployed, then the deployment process is simple, but the response time is delayed
Solution Approach 1:
The system incorporates automatic detection means that continuously monitor for fire conditions before manual intervention is needed. When fire is detected, the pull-out device is automatically triggered to deploy the blanket, eliminating the delay between fire detection and blanket deployment.
Solution Approach 2:
The automatic detection means provide feedback about fire conditions to the control system, which then automatically activates the pull-out device. This closed-loop feedback system ensures rapid response by continuously monitoring and automatically reacting to fire threats without manual intervention delays.
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 solution provides rapid, efficient, and effective fire containment by automatically or manually deploying a fire protection blanket to prevent fire spread, ensuring oxygen isolation and maintaining protection until firefighting teams arrive.
Implementation Method 1
Positioning the fire blanket over the motor vehicle involves considerable effort... in order to isolate the fire and thus suppress further spread... to prevent an influx of oxygen as far as possible and thus insulate the vehicle
Implementation Method 2
The fire blanket should withstand the heat of the fire until professional assistance arrives... to insulate the vehicle as best as possible

AI summary
The invention relates to a fire protection device comprising a fire protection blanket (3) which can be placed over a potentially burning object positioned on a parking space (5), in particular such as a battery-operated vehicle (6), in order to prevent the spread of fire starting from or across the object. The fire protection blanket (3) is compactly gathered into a bale (32), in particular rolled up and/or folded together, into a roll (32), is accommodated in a box-like housing (1) which is or can be mounted on the parking space (5), and is connected to a pull-out device (4), by means of which the fire protection blanket can be manually or automatically placed completely over the object in the event of fire or risk of fire such that its side portions (31) rest completely or at least largely on the parking space floor on every side in order to prevent as much oxygen influx as possible (FIG. 1).
