Modular Iron Entry Tool for Firefighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firefighters face challenges with heavy and cumbersome tools, including separate devices for forced entry, smoke blocking, and lighting, which are bulky and hazardous to carry and use in hazardous environments, particularly in building fires and traffic collisions.
Innovation Solution
A modular iron entry tool with a telescoping rod system, integrated canvas for smoke blocking and patient protection, and a power alarm system, which combines functions like a door wedge, patient carrier, and navigation aid, allowing for efficient tool use and reduced hazards during emergencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If firefighters carry separate forced entry tools, smoke blocking devices, and alarm systems, then each function can be performed effectively, but the total weight and bulk of equipment becomes unmanageably heavy and cumbersome
Solution Approach 1:
The patent combines multiple separate firefighting tools into a single integrated apparatus. The forced entry tool includes an integrated smoke blocking device with alarm system, merging functions that were previously separate. The smoke blocking device incorporates support frames, canvas material, and alarm components into one unified structure that can be deployed as a single unit.
Solution Approach 2:
The integrated apparatus serves multiple functions simultaneously. The smoke blocking device not only blocks smoke but also provides structural support through its frame, houses alarm systems, and can be configured in various ways depending on the emergency situation. This multi-functional design eliminates the need for firefighters to carry and manage multiple separate specialized tools.
2Reliability
If smoke blocking devices use support frames and require door removal for installation, then the smoke blocking function is effective, but the installation process becomes complex and time-consuming
Solution Approach 1:
The support frames are designed to be adaptable and flexible in installation. Rather than requiring fixed installation methods or door removal, the frames can be configured in multiple ways depending on the opening type and situation. The dynamic design allows for quick adjustment and deployment across different scenarios without complex installation procedures.
3Reliability
If a horizontal bar is installed on the upper portion of the opening for hanging the canvas, then the smoke blocking function is achieved, but it creates a hazard that firefighters may hit their heads
Solution Approach 1:
The hazardous horizontal bar component is removed from the design. Instead of installing a rigid bar across the upper opening that protrudes into the passage, the patent uses alternative support mechanisms that do not create head injury risks. The canvas is supported in a way that maintains smoke blocking effectiveness while eliminating the protruding hazard.
4Reliability
If most smoke blocking devices are bulky and large, then they provide adequate smoke blocking coverage, but they present additional challenges for firefighters to carry and store on engines
Solution Approach 1:
The support frames are designed to nest within each other when not in use, significantly reducing the storage volume required. The canvas material can be rolled or folded and stored within the nested frame structure. This nesting capability allows the relatively large smoke blocking device to be compacted into a manageable size for transport and storage on fire engines.

AI summary
The iron entry tool is a multifunctional device for building and vehicle forced entry, flow path blocking, rescue tarp, patient carrier. The entry tool comprises a modular structure that can fit into a wide variety of building openings and vehicle doors that are cut out under traffic collision incidents. The power alarm system of the tool provides critical safety features for rapid egress of firefighters. The canvas of the entry tool can be conveniently rewound to provide an user an efficient way to store and carry the Roses iron entry toll.
