Fire Hose Loading Rail and Catch for Safer Reloading

Solution Overview

Problem

Firefighters face challenges in safely and efficiently loading fire hoses into firetruck hose beds, requiring significant manual effort and posing risks of injury or accidents due to the weight and length of the hoses.

Innovation Solution

A loading system for firetrucks featuring a frame with a movable rail and hose catch mechanism that can grip and move fire hoses automatically, reducing the need for manual handling and minimizing physical strain.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If firefighters manually roll or fold up the flexible hose to load it into the hose bed, then the hose can be loaded into the firetruck, but the process requires significant time and effort and poses safety risks to firefighters

Engineering Contradiction:

Improvehose loading speedVSAvoidfirefighter safety and effort

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The hose loading system enables the hose to load itself into the hose bed automatically. The rail moves along the track and the hose catch mechanism propels the hose without requiring firefighters to manually handle the heavy hose, making the system self-servicing and eliminating the need for human physical effort in the loading process.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical system (firefighters physically rolling and folding the hose) with an automated mechanical system consisting of a motor-driven rail and hose catch mechanism. This substitution eliminates the need for human physical intervention while maintaining the hose loading function.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If firefighters climb up onto the fire truck to load the hose into the hose bed, then the hose can be loaded, but firefighters risk falling off the truck or injuring their back

Engineering Contradiction:

Improvehose loading accessibilityVSAvoidfirefighter safety

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The hose loading system enables the hose to load itself into the hose bed automatically. The rail moves along the track and the hose catch mechanism propels the hose without requiring firefighters to manually handle the heavy hose, making the system self-servicing and eliminating the need for human physical effort in the loading process.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent introduces an intermediary mechanical system (the automated rail and hose catch mechanism) between the hose and the firefighters. This intermediary performs the dangerous task of hose handling, allowing firefighters to remain safely on the ground while the system completes the loading operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If multiple firefighters are used to manually handle the hose, then the hose can be controlled during loading, but the process becomes more time-consuming and labor-intensive

Engineering Contradiction:

Improvehose control during loadingVSAvoidhose reloading time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the manual mechanical system (firefighters physically rolling and folding the hose) with an automated mechanical system consisting of a motor-driven rail and hose catch mechanism. This substitution eliminates the need for human physical intervention while maintaining the hose loading function.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The automated hose loading system performs the loading operation continuously and efficiently. The motor-driven rail moves the hose catch along the track in a continuous motion, propelling the hose into the hose bed without the interruptions and coordination delays associated with manual handling by multiple firefighters.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A loading system is disclosed comprising a frame mountable to a hose bed of a firetruck and including a track, a rail movable along the track, and a hose catch operatively coupled to the rail. The rail comprises a body and an arm pivotably attached to the body and transitionable between a gripping state, where the arm grippingly engages a firehose and thereby enables the hose catch to move the firehose within the frame, and a released state, where the arm releases the firehose and thereby enables the hose catch to move relative to the firehose.
