Collapsible Fire-Resistant Cabin Container for Lithium-Ion Battery Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In commercial aircraft, dangerous objects like overheated electronic devices or damaged lithium-ion batteries pose a fire risk within the closed passenger cabin, necessitating a safe handling solution that balances risk mitigation with passenger comfort.
Innovation Solution
A compact, fire-resistant apparatus comprising a retaining plate, a refractory housing wall, and an opening frame that can be packed down or expanded, allowing for safe storage and containment of hazardous items within the cabin, using materials like Kevlar and fire-extinguishing granular materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dangerous objects are removed directly from the passenger cabin, then the fire risk is reduced, but the passenger comfort and cabin accessibility are compromised
Solution Approach 1:
A fire-resistant container serves as an intermediary device between the dangerous object and the passenger cabin environment. The container allows safe handling and temporary storage of hazardous items (overheated devices, damaged batteries) within the cabin without directly exposing the cabin to fire risks, thus resolving the contradiction between risk reduction and accessibility.
2Reliability
If a fire-resistant container is provided for dangerous objects, then the safety is improved, but the installation space and device complexity increase
Solution Approach 1:
The container employs a collapsible housing wall that can transition between an expanded state (when containing objects) and a compressed state (when empty). This dynamic structure allows the container to adapt its volume based on usage, reducing installation space requirements while maintaining safety functionality when needed.
Solution Approach 2:
The collapsible housing wall can be folded or compressed into a compact form that nests within or alongside the opening frame and retaining plate structure, minimizing the overall footprint when the container is not in use, thus reducing installation space complexity.
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 fires by providing a safe, space-efficient container for dangerous objects, allowing for immediate risk suppression and safe storage during flights, even with long durations, without compromising cabin operations or passenger comfort.
Implementation Method 1
a housing wall which is arranged on the retaining plate, which can be packed down and which is composed of a refractory material

AI summary
An apparatus for handling dangerous objects in a closed vehicle cabin includes a retaining plate for fastening of the apparatus, a housing wall which is arranged on the retaining plate, which can be packed down and which is composed of a refractory material, and an opening frame which is connected at least to the housing wall and which has a closable opening, wherein the housing wall which can be packed down can be brought into a packed-down state and into an expanded state, wherein, in the folded-out state, the housing wall, together with the retaining plate and the opening frame, provides a cavity which can be reached from outside of the housing wall through the opening.
