Weighted Fire Blanket for Lithium-Ion Device Fire Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire blankets are ineffective for extinguishing fires involving electronic devices, particularly those with lithium ion batteries.
Innovation Solution
A fire blanket with a central handle, weighted chains along the edge, and corner straps, designed to smother electronic device fires by draping over the device, holding it down with weighted chains, and securing the remains with corner straps after cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fire blankets are used for electronic device fires, then the blanket can be draped over the fire, but the blanket cannot be held down effectively and fails to suppress the fire
Solution Approach 1:
The patent changes the physical parameters of the fire blanket by adding weighted chains along the edges and strategic weights at corners. This modifies the weight distribution and holding characteristics of the blanket, enabling it to be held down effectively over electronic devices without requiring constant manual pressure, thus resolving the contradiction between reliability and ease of operation.
2Stability of the object's composition
If the blanket is made fully rigid to maintain shape, then it can cover the fire uniformly, but it becomes difficult to drape and position quickly
Solution Approach 1:
The patent utilizes a flexible blanket material that can be easily draped and positioned quickly, while the added weights and chains provide the necessary stability to maintain coverage. The flexible nature allows rapid deployment, while the weighted edges ensure the blanket stays in place, resolving the contradiction between stability and speed.
3Ease of operation
If the blanket is made lightweight for easy handling, then it can be quickly deployed, but it cannot be held down effectively over the fire
Solution Approach 1:
The patent modifies the weight parameter of the blanket by adding strategic weights and chains, transforming it from a lightweight blanket that is easy to handle but difficult to hold down, to a balanced system that maintains ease of deployment while achieving effective holding capability through the added weight distribution.
4Reliability
If weighted chains are added to hold down the blanket, then fire suppression effectiveness improves, but device complexity increases
Solution Approach 1:
The patent segments the weight distribution by placing weights at specific locations (corners and along edges) rather than distributing weight uniformly throughout the blanket. This segmented approach to adding weight provides effective holding capability while minimizing the overall complexity increase, as the weights are added as discrete, simple components rather than integrating complexity throughout the entire structure.
