Modular Airbag System with Detachable Compartments for Backpack Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal airbag systems for avalanche protection are cumbersome and inflexible, making it difficult for users to wear a backpack while using the airbag, as strapping on two backpacks is mechanically challenging and can interfere with the airbag's deployment mechanism.
Innovation Solution
A modular airbag system with detachable side airbag compartments and adjustable straps that can be securely attached to a backpack, allowing normal strapping and deployment without interference, featuring gas canisters for inflation and manual/automatic triggering, and additional body straps for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-piece backpack airbag system is used, then the airbag provides continuous protection coverage, but the user cannot wear a personal backpack simultaneously due to mechanical interference and deployment conflicts
Solution Approach 1:
The airbag system is divided into separate modular components: a backpack carrier system and detachable airbag compartments. This segmentation allows the airbag compartments to be attached to the carrier system or worn independently, enabling users to wear personal backpacks while maintaining full airbag protection coverage.
2Device complexity
If a single-piece backpack airbag system is used, then the structure is simple and integrated, but the system becomes cumbersome and inflexible for users
Solution Approach 1:
The system transitions from a static integrated design to a dynamic modular configuration. The airbag compartments can be attached, detached, and repositioned on the backpack carrier system, allowing users to adjust the configuration based on their needs and easily wear personal backpacks without compromising the airbag system.
3Adaptability or versatility
If two backpacks are strapped on simultaneously, then the user can carry personal equipment and use the airbag, but the strapping becomes mechanically difficult and may interfere with airbag deployment
Solution Approach 1:
The backpack carrier system serves as an intermediary structure between the user's personal backpack and the airbag compartments. The carrier system provides dedicated attachment points and structural support, allowing personal backpacks to be worn comfortably without interfering with airbag deployment mechanisms.
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
Enables users to wear a backpack while using the airbag system without deployment interference, providing secure and flexible attachment and inflation mechanisms for enhanced protection in avalanche situations.
Implementation Method 1
a filling unit for the buoyant body, and a compressed gas unit having a compressed gas tank and a release unit
Implementation Method 2
the garment is inflated in a manual or automatised fashion with air and/or oxygen... keeps its user at the surface of the avalanche

AI summary
A modular airbag system may include at least one inflatable airbag configured to deploy outward on a side(s) of the airbag system, for example, in two opposite substantially horizontal directions, at least one airbag compartment, and one or more straps configured to strap the modular airbag system securely to one of a user's body and/or an object, and configured to release the modular airbag system from one of the user's body and/or the object.
