Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices and methods for supporting firefighters while cutting holes in roofs during vertical ventilation are inadequate, leading to dangerous situations due to lack of stability, reliability, and ease of use.
Innovation Solution
A reusable support device that can be removably connected to a ladder, providing a stable foothold and adjustable positioning to ensure safety and ease of use, even in challenging environments like steep roofs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a firefighter uses a ladder to reach the roof for vertical ventilation, then they can access the roof, but they lack stable footing and are at risk of falling
Solution Approach 1:
The support device integrates multiple functions into a nested structure where the foot support platform, ladder rungs, and connection mechanisms are hierarchically arranged. The platform nests onto the ladder structure, creating a compact yet stable configuration that provides both access and stability.
Solution Approach 2:
The invention adds a horizontal dimension to the traditional vertical ladder approach by extending a platform that protrudes from the ladder structure. This creates a three-dimensional work surface that allows firefighters to distribute their weight and maintain balance while performing ventilation tasks.
2Ease of operation
If a firefighter embeds a Halligan tool into the roof to create footing, then they can gain some stability, but the process is time-consuming and the footing is insufficient
Solution Approach 1:
The support device is pre-assembled with the foot support platform already attached to the ladder structure before the firefighter arrives at the scene. This eliminates the need for time-consuming on-site assembly or the dangerous process of embedding tools into the roof to create footing.
Solution Approach 2:
The support device uses a modular design where the platform can be quickly deployed and removed after use. The device is designed for single-use or limited-use scenarios where rapid deployment is more important than long-term durability, allowing firefighters to quickly set up and then remove the device after completing ventilation tasks.
3Ease of operation
If a firefighter uses an aerial device for support, then they can have stable footing, but coordination with the truck operator is complex and limits mobility
Solution Approach 1:
The invention extracts the essential function of aerial device support (providing a stable platform) and integrates it directly onto the portable ladder. This eliminates the need for a separate aerial device and the complex coordination between firefighters and truck operators, while maintaining the stability benefit.
Solution Approach 2:
The support device is designed to be universally compatible with standard fire service ladders and can be used in various ventilation scenarios. The platform can accommodate different tool positions and firefighter stances, providing multi-functional support without requiring specialized equipment or extensive training.
4Ease of operation
If a firefighter stands on a narrow Halligan tool shaft, then they can reach the cutting position, but they risk slipping and muscle injury
Solution Approach 1:
The invention merges the ladder structure with a broad foot support platform, combining the access function of the ladder with the stability function of a wide standing surface. This integrated design allows firefighters to maintain both access to the cutting position and stable footing simultaneously.
Solution Approach 2:
The platform is designed with varying surface characteristics in different zones - the standing area has enhanced friction surfaces and contours for foot stability, while the edges and support structures are optimized for structural strength and attachment to the ladder. This localized optimization of properties enhances overall performance.

AI summary
A device and related methods of use may be used to aid in supporting an individual, equipment, or tools from a ladder or similar device or independently. The device may be removably attached to the ladder or similar device and may, optionally, further optionally at least partially rest against a roof. When a user, such as a firefighter, needs to be on a roof, such as when cutting steep angle roof ventilation holes or vertical ventilation holes, the user may stand or apply force or weight or rest equipment at least partially on the device. The device may provide a larger or more stable area for supporting the firefighter or equipment than with conventional and currently available methods and tools. The device may also optionally be lockable to a ladder, may have gripping features or surfaces, and may be configured to retain tools such as saws or roofhooks.
