Snap-To-Grid Sprinkler Bracket for Torsion-Resistant T-Bar Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire sprinkler support assemblies are cumbersome to install and do not efficiently secure sprinkler heads to T-bar beams in ceiling grid systems, particularly under high fluid pressure conditions, which can lead to misdirection of the fire suppression stream.
Innovation Solution
A bracket assembly for fire sprinkler support systems that includes a bracket bar extending transverse to a beam, with a seating frame and a second plate that can be rotated relative to a first plate, utilizing a fastener or lever assembly to securely anchor the sprinkler head to the beam, allowing for easy installation and secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fasteners (screws or bolts) are used to secure the bracket to the beam, then the connection strength is sufficient to withstand high fluid pressure, but the installation process becomes time-consuming and requires special tools
Solution Approach 1:
The bracket assembly transitions from a static fastened state to a dynamic installation process where the second plate rotates relative to the first plate, allowing the fastener to engage and lock into place. This dynamic mechanism enables tool-free installation while maintaining secure connection.
Solution Approach 2:
The bracket assembly is designed to be self-installing through the snap-to-grid mechanism. The second plate's rotation and the fastener's engagement automatically secure the bracket to the beam without requiring external tools or complex fastening procedures.
2Productivity
If the bracket assembly uses a rotatable second plate with fastener, then the installation speed increases, but the device complexity increases compared to simple fasteners
Solution Approach 1:
The bracket assembly is divided into distinct functional segments: the first plate for mounting, the second plate for engagement, and the fastener for securing. This segmentation allows each component to perform its specific function efficiently while keeping the overall design manageable.
Solution Approach 2:
The rotation mechanism and fastening function are merged into a single integrated action. Rotating the second plate simultaneously engages the fastener and secures the bracket to the beam, combining multiple operations into one motion.
3Reliability
If the bracket assembly securely anchors to the beam, then it can resist side, rotational, and torsional forces under high pressure, but the structural complexity increases
Solution Approach 1:
The fastening function is extracted from the main bracket structure and implemented through the separate second plate and fastener mechanism. This allows the primary bracket structure to remain relatively simple while the extraction of the fastening function provides the necessary anchoring capability.
Solution Approach 2:
The first plate is pre-configured with mounting features that align with the beam structure. This preliminary preparation ensures that when the second plate rotates and the fastener engages, the connection is immediately secure and capable of withstanding operational forces.
