Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firefighting training equipment, such as steel shipping containers and 'dolls house' structures, are costly and logistically challenging to deploy, limiting access to effective training for volunteer firefighters due to high production costs and the need for frequent replacement.
Innovation Solution
A portable, small-scale firefighting training unit comprising a metal container with a combustible liner made of particle board, designed for easy assembly and disassembly, allowing for field training without the need for stapling or gluing, and featuring a metal container with a lid and access opening to simulate fire behavior and ventilation effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If steel shipping containers are used for firefighting training, then training effectiveness is improved, but cost and logistics become prohibitive for volunteer departments
Solution Approach 1:
The patent creates a simplified copy of the steel container training system using a metal pan with a combustible liner. This copy retains the essential training function of demonstrating fire behavior while dramatically reducing production cost and portability requirements, making it accessible to volunteer departments.
Solution Approach 2:
The training unit uses inexpensive materials including a metal pan and combustible liner made from particle board or similar materials. The unit is designed to be consumed during training demonstrations, eliminating the need for expensive, durable steel containers while providing sufficient training value for single-use or limited-use scenarios.
2Weight of moving object
If dolls house structures are used for field training, then portability is improved, but assembly complexity increases due to stapling and gluing requirements
Solution Approach 1:
The training unit is divided into separate components: a metal pan and a combustible liner made from pre-cut panels. These segments can be easily transported separately and assembled without complex joining methods, reducing both portability burden and assembly complexity.
Solution Approach 2:
The patent extracts the essential training function from the complex dolls house structure by using a simple metal pan with a combustible liner. This eliminates the need for stapling and gluing while maintaining the ability to demonstrate fire behavior, thereby reducing assembly complexity.
3Weight of moving object
If dolls house structures are used for training, then portability is improved, but production cost increases due to frequent replacement needs
Solution Approach 1:
The combustible liner is designed as an inexpensive, consumable component that can be easily replaced after each training demonstration. Using cheap materials like particle board allows frequent replacement without significant cost, making the portable training unit economically viable for volunteer departments.
4Manufacturing precision
If tight joints are used in dolls house construction, then fire simulation accuracy is improved, but manufacturing time increases
Solution Approach 1:
The patent removes the requirement for tight joints by using a metal pan with a combustible liner that relies on the material's inherent properties rather than structural integrity. The liner panels can be loosely fitted to the pan walls, eliminating time-consuming precision assembly while maintaining fire simulation accuracy through proper material selection and configuration.

AI summary
A metal container with a combustible liner for use as a portable firefighting training unit. The combustible liner is formed of particle board sections loosely assembled inside the metal container with an opening in the liner in registry with an access opening in the metal container. The unit may be used to demonstrate various phenomena associated with a developing fire including the flammability of unburned products of combustion, hose stream techniques with a spray bottle filled with water, flashover and backdraft.
