External Standpipe Bracket Mounting for High-Rise Water Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing standpipe systems in high-rise buildings and structures are limited by outdated regulations and inadequate maintenance, often failing to provide reliable water supply during emergencies, necessitating firefighters to rely on on-site water sources.
Innovation Solution
A portable external standpipe tool with a bracket system that securely fastens a standard supply line to external structures, such as railings or ladder trucks, allowing for rapid deployment and support of pressurized water lines up to 100 stories, using a combination of brackets, sleeves, and fasteners for secure attachment and weight-bearing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanent standpipe systems are installed in high-rise buildings, then water supply for firefighting is enabled, but the systems are limited by outdated regulations and inadequate maintenance, leading to unreliable operation
Solution Approach 1:
The standpipe system is segmented into modular components (brackets, fasteners, mounting structures) that can be independently installed, maintained, and replaced. This segmentation allows firefighters to establish functional segments without requiring the entire permanent system to be operational, thereby improving reliability while reducing dependence on maintenance-prone permanent infrastructure.
Solution Approach 2:
The patent employs temporary but reliable mounting components that can be quickly deployed and discarded after use. These components are designed for single-use emergency situations rather than permanent installation, eliminating maintenance requirements while ensuring operational reliability when needed most.
2Ease of operation
If firefighters rely on on-site water sources due to standpipe system failures, then operational independence is achieved, but response effectiveness is reduced without reliable external water supply
Solution Approach 1:
The patent introduces an intermediary mounting system that connects external water supply lines to building structures at multiple elevations. This intermediary system bridges the gap between external water sources and interior firefighting operations, enabling reliable water delivery without requiring dependence on either failed permanent standpipes or limited on-site sources.
3Productivity
If a portable external standpipe tool is deployed to establish ad hoc water supply, then rapid deployment is achieved, but secure attachment to external structures must be ensured under pressurized conditions
Solution Approach 1:
The mounting structures and brackets are pre-configured with attachment features and adjustment mechanisms that enable rapid securing to external structures. The preliminary design of these components allows firefighters to quickly establish secure attachments without time-consuming assembly or adjustment, simultaneously achieving rapid deployment and reliable strength.
Solution Approach 2:
The bracket system incorporates dynamic adjustment capabilities that allow the mounting structure to adapt to various external surface geometries and conditions. This dynamic adaptability enables secure attachment across different structures while maintaining rapid deployment capability, as the system self-adjusts rather than requiring precise pre-positioning.

AI summary
An external portable standpipe tool is an apparatus used to secure the nozzle of a pressurized water supply line to provide a reliable water supply for fire suppression in place of a conventional standpipe. The external portable standpipe tool utilizes a first bracket, a second bracket, an external mounting structure, and a plurality of bracket fasteners to mount a pressurized water supply line in a desirable location. The first bracket is removably engaged to the second bracket, enabling a user to capture and retain the nozzle and supply line. The plurality of bracket fasteners is engaged into the first bracket and the second bracket is used to fix them together. The external mounting structure attaches the combined assembly of the first bracket and the second bracket to an external structure, such as a railing or support beam.
