Preassembled PVC Water Transfer Pipe for Rural Firefighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In rural fire fighting scenarios where fire hydrants are not accessible, the time-consuming setup of dump tanks, draft tanks, and water transfer pipes allows fires to spread and cause more damage due to the impracticality of installing hydrants in sparse populations.
Innovation Solution
A preassembled water transfer pipe system consisting of a generally hollow conduit member made from PVC, with a predetermined length and cross-sectional shape, and a connection member for receiving a hose, designed to efficiently transfer water from a dump tank to a draft tank, reducing setup time and enhancing firefighting capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If firefighters assemble equipment piece by piece (dump tanks, draft tanks, water transfer pipes), then the equipment can be customized and adapted to specific fire scenes, but the setup time increases significantly allowing fire to spread
Solution Approach 1:
The water transfer pipe is preassembled with connection members attached to ends before reaching the fire scene. This preliminary assembly of components eliminates the time-consuming on-site assembly process while maintaining the ability to adapt to different fire scenes through configurable pipe sections and connection types.
2Speed
If fire hydrants are installed in rural areas with sparse population, then water delivery speed increases, but the cost becomes prohibitively high
Solution Approach 1:
The water transfer system is divided into modular segments including the preassembled pipe with connection members, dump tank, and draft tank. This segmentation allows the system to be transported in manageable pieces and assembled quickly at the fire scene, providing hydrant-like speed without the prohibitive cost of permanent hydrant installation in rural areas.
3Adaptability or versatility
If multiple separate components are used for water transfer (dump tank, draft tank, transfer pipes), then the system can be flexible in configuration, but the complexity of assembly increases
Solution Approach 1:
The connection members are merged with the water transfer pipe during manufacturing, creating a preassembled unit that reduces the number of separate components firefighters must handle and assemble. This merging maintains configuration flexibility through the pipe's inherent design while significantly reducing assembly complexity at the fire scene.
