Firehose Backpack Layout for Protected Carry and Fast Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backpack devices for firefighters do not efficiently accommodate firehoses with an open bottom end for insertion and secure them externally, lacking features for easy access and external transport.
Innovation Solution
A backpack with an open bottom end divided into two halves, flaps for closure, pouches for tools, and a shoulder harness for hands-free carrying, along with straps and couplers for securing firehoses externally and internally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If firehoses are carried in traditional backpack devices with open top ends, then firefighters can access firehoses, but the firehoses are exposed to elements and lack secure external transport capability
Solution Approach 1:
The patent inverts the traditional backpack design by placing the open end at the bottom rather than the top. Firehoses are inserted through the bottom opening and secured externally with straps and couplers, while the top remains closed with a cover. This inversion protects firehoses from elements while maintaining easy access through external securing mechanisms.
Solution Approach 2:
The patent employs nesting by placing firehoses inside the backpack container for protection, while external straps and couplers provide an additional layer of securing. The firehoses are nested within the backpack interior space, and the external securing system nested on the backpack exterior works together to provide both protection and secure transport.
2Ease of operation
If firehoses are secured externally with straps, then external transport is facilitated, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing straps and couplers that serve multiple functions: securing firehoses externally for transport, allowing quick release for deployment, and providing adjustable positioning. The same securing mechanism handles both transport and deployment requirements, reducing the need for separate complex systems.
3Object-affected harmful factors
If the backpack interior is divided into two halves, then firehoses are organized and protected, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the backpack interior into two distinct halves or compartments. This segmentation organizes firehoses into separate sections, preventing damage from entanglement or movement, while the division is achieved through simple structural partitioning rather than complex mechanisms.

AI summary
A firehose backpack device includes a backpack which an open a bottom end to access an interior space defined by the backpack to facilitate fire hoses to be inserted into the interior space for storing the fire hoses. The interior space is divided into a first half and a second half which each contain a respective fire hose. A first flap is disposed on the bottom end of the backpack for closing the first half wherein the first flap and a second flap is disposed on the bottom end of the backpack for closing the second half. A pair of pouches is each attached to the backpack to contain tools and accessories related to employing fire hoses. A shoulder harness is attached to the backpack and the shoulder harness can be worn over shoulders of a firefighter thereby facilitating the firefighter to carry the backpack on the firefighter's back.
