Telescopic Sprinkler Head Assembly for Fast Precise Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of fire sprinkler systems is challenging due to the difficulty in adjusting the height and alignment of sprinkler heads, requiring precise cutting and re-cutting of piping, which is time-consuming, costly, and often necessitates skilled labor, while existing solutions are either expensive or time-consuming.
Innovation Solution
A telescopic pipe assembly that allows for adjustable horizontal and vertical positioning of sprinkler heads using telescoping pipes, eliminating the need for precise cutting and reducing the number of joints, thereby simplifying the installation process and reducing labor and material costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional hard piping with precise cutting is used to position sprinkler heads, then positioning accuracy is improved, but installation time and labor cost increase
Solution Approach 1:
The patent applies the dynamics principle by replacing static, fixed-length pipe sections with a dynamic telescopic mechanism that allows continuous adjustment of pipe length. The telescopic pipe assembly includes an inner pipe that can slide within an outer pipe, enabling the sprinkler head to be positioned at various heights and locations without cutting or splicing. This dynamic adjustment capability resolves the contradiction by providing both positioning accuracy and installation efficiency.
2Strength
If traditional hard piping with multiple joints is used to connect sprinkler heads, then structural strength is improved, but leak risk increases
Solution Approach 1:
The patent applies the merging principle by combining multiple pipe sections into a single telescopic assembly. Instead of using separate pipe sections connected by multiple joints (threaded connections, couplings, or welds), the invention integrates the connection function into one unified telescopic structure. This reduces the number of potential leak points while maintaining structural integrity through the telescopic mechanism's inherent strength.
3Ease of manufacture
If pre-cut pipe lengths are used from fabricators, then installation ease is improved, but material cost increases
Solution Approach 1:
The patent applies the universality principle by designing a telescopic pipe assembly that can serve multiple functions: it provides structural support, enables positioning adjustment, and eliminates the need for custom-cut pipe sections. This universal component replaces the need for multiple pre-cut pipe lengths, reducing material waste and cost while maintaining installation ease. The single telescopic assembly can accommodate various sprinkler head positions without requiring different pipe lengths.
4Manufacturing precision
If skilled pipefitters perform precise pipe cutting and installation, then installation quality is improved, but labor cost increases
Solution Approach 1:
The patent applies the self-service principle by designing a telescopic pipe assembly that enables installers to adjust sprinkler head positions independently without requiring skilled pipefitters. The telescopic mechanism allows for easy length adjustment and positioning through simple operations, eliminating the need for specialized cutting and threading skills. This self-adjusting capability maintains installation quality while reducing labor costs by enabling less skilled workers to perform the installation.

AI summary
Assembly for connecting a branch line to a fire-sprinkler head, and for adjusting longitudinal and horizontal position of the sprinkler head. The assembly may include: a first-pipe section, a second-pipe section, and a third-pipe section. First-pipe section has telescoping lower and upper pipes configured to travel axially relative to each other upwardly and downwardly along a longitudinal axis. Second-pipe section has telescoping right, and left pipes configured to travel axially relative to each other along a horizontal axis. Third-pipe section is between first-pipe section and second-pipe section, and is curved. First-pipe section is configured to engage a sprinkler head and permit the sprinkler head to travel longitudinally upon telescopic adjustment of the lower and upper pipes. Second-pipe section attaches to the sprinkler-branch line, and permits the sprinkler head to travel horizontally upon telescopic adjustment of the right and left pipes with respect to each other.
