Dry Pendent Sprinkler Barrel and Fitting System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for installing and removing dry pendent sprinklers are time-consuming and damaging, requiring significant effort and often resulting in costly repairs due to the need for extensive digging around the sprinkler housing to access the piping system.
Innovation Solution
A system comprising a fitting with teeth that complements the sprinkler head, allowing for releasable attachment with a barrel that includes slots and extensions for easy installation and removal, facilitated by a socket wrench for efficient rotation and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional methods are used to install and remove sprinkler heads, then the connection between the housing and piping system can be accessed, but the process requires vast amounts of time and significant effort, and the area surrounding the sprinkler is often damaged
Solution Approach 1:
The system divides the sprinkler assembly into separable components: a sprinkler housing that can be detached from the piping system, and a barrel component that remains attached to the pipe. This segmentation allows the sprinkler head to be quickly removed and replaced without affecting the permanent piping infrastructure, dramatically reducing installation and removal time while eliminating damage to surrounding areas.
Solution Approach 2:
The system employs a dynamic, reversible connection mechanism between the barrel and sprinkler housing. The barrel includes an internal thread that engages with an external thread on the sprinkler housing, allowing for quick assembly and disassembly. This dynamic connection enables the sprinkler to be easily installed and removed without permanent modifications or extensive digging, directly addressing the time and effort constraints.
2Ease of repair
If traditional methods are used to install and remove sprinkler heads, then the connection between the housing and piping system can be accessed, but the area surrounding the sprinkler is often damaged, leading to costly repairs
Solution Approach 1:
By segmenting the sprinkler system into a removable housing and a permanent barrel-pipe assembly, the invention enables easy replacement of the sprinkler head without disturbing the surrounding area. The barrel remains fixed to the piping system while the sprinkler housing can be independently removed and replaced, eliminating the need for extensive digging and preventing damage to surrounding structures.
Solution Approach 2:
The invention extracts the sprinkler housing from the permanent piping infrastructure by introducing a separable barrel component. This extraction allows the sprinkler to be removed and replaced without affecting the underlying piping system or surrounding areas, thereby eliminating the harmful effect of damage to the surrounding environment while maintaining ease of repair.
3Productivity
If a separable connection system is used between the sprinkler housing and piping system, then installation and removal time is reduced, but the system requires additional components (barrel, threads, fitting)
Solution Approach 1:
The invention merges the barrel component with both the piping system and the sprinkler housing through threaded connections. The barrel acts as an intermediary that combines the permanent pipe fitting with the removable sprinkler housing, creating a unified assembly that enables quick replacement while minimizing the number of separate components needed. This merging approach reduces complexity compared to having entirely separate coupling mechanisms.
Solution Approach 2:
The barrel component serves multiple functions: it provides a permanent attachment point to the piping system, creates a threaded interface for the sprinkler housing, and enables quick disassembly and reassembly. This multi-functionality reduces the need for additional specialized components, thereby increasing installation efficiency without proportionally increasing system complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and efficient installation and removal of dry pendent sprinklers with reduced damage and labor, requiring only a single user and minimal tools, thus reducing installation and removal time and associated costs.
Implementation Method 1
During a fire, the heat-sensitive fluid expands within the bulb. When a predetermined temperature is reached, the heat-sensitive fluid applies hydraulic pressure outwardly against the bulb normal to the long axis, causing the bulb to shatter.

AI summary
The invention is a system used to effectively install and remove dry sprinkler pendent heads. The system includes a barrel that cooperates with an associated fitting configured about the exterior of the outer casing tube of a pendent sprinkler. Specifically, the barrel includes a slot channel and extension sized and shaped to house one or more fitting teeth to releasably join the fitting and the barrel. Once joined, the barrel can be rotated to thereby install or remove an attached pendent sprinkler.
