Movable Sprinkler Deflector for Concealed Installation Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire protection systems face challenges in installing sprinklers with concealed configurations due to limitations in aligning the sprinkler and deflector positioning, which restricts flexibility and optimal installation in various building structures.
Innovation Solution
A sprinkler system with a deflector that moves along a plurality of pins from an undeployed to a deployed position, allowing for flexible installation and alignment with piping, including concealed and non-concealed applications, using a thermally responsive trigger for activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sprinkler uses a fixed deflector position, then the structure is simple, but the installation flexibility is limited
Solution Approach 1:
The deflector is made movable along the pins instead of being fixed, allowing it to transition between retracted and deployed positions. This dynamic positioning enables installation flexibility while maintaining a relatively simple mechanical structure using pins and flanges.
Solution Approach 2:
The deflector assembly is segmented into multiple components (deflector body, pins, flanges) that can move independently relative to each other. This segmentation allows the deflector to be positioned at different locations along the pins during installation while keeping the overall structure manageable.
2Adaptability or versatility
If the sprinkler body is positioned far from the deflector, then concealed installation is easier, but fluid distribution effectiveness decreases
Solution Approach 1:
The deflector's movable position along the pins allows it to be extended closer to the sprinkler body when needed for effective fluid distribution, while still permitting retraction for concealed installations. This dynamic adjustment resolves the conflict between installation concealment and operational effectiveness.

AI summary
A sprinkler includes a connector, a body, at least one pin, and a deflector. The connector extends between an inlet end and an outlet end. The body includes a pin wall extending from the outlet end of the connector. The pin wall defines at least one pin receiver. The body wall extends from the pin wall. The pin wall and the body wall define a chamber. The at least one pin is fixed with the at least one pin receiver. The deflector is coupled with the at least one pin to move within the chamber along the at least one pin responsive to a trigger condition from an undeployed state to a deployed state.
