Ceiling Frame Clip Assembly for Vibration-Resistant Sprinkler Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceiling frame mounting assemblies fail to adequately support connected systems during high vibratory and heat conditions, such as those encountered during natural disasters like earthquakes or fires.
Innovation Solution
A clip assembly comprising a frame and bracket with a skirt, leg, and a pair of fasteners that securely attach to a ceiling trave, using arcuate guides and bent wings to clamp the frame in place, ensuring stability under extreme conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple mounting assembly is used, then ease of installation is improved, but reliability under high vibratory and heat conditions deteriorates
Solution Approach 1:
The mounting assembly is divided into distinct functional components: a U-shaped channel member for attachment to the ceiling frame, a separate bracket member for supporting the system, and fastening elements. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity of installation.
Solution Approach 2:
The channel member is pre-formed with a U-shaped configuration that is designed to fit over the ceiling frame flange. This preliminary shaping allows the installer to simply slide the channel over the frame without requiring complex assembly steps, while the pre-formed geometry ensures reliable engagement under vibratory conditions.
2Reliability
If a complex mounting assembly is used, then reliability under high vibratory and heat conditions is improved, but ease of installation deteriorates
Solution Approach 1:
The channel member and bracket member are designed to work together as an integrated system. The channel's U-shaped profile combines the attachment function and the support function into a single structural element that simply slides over the ceiling frame, eliminating the need for complex multi-step installation procedures while maintaining high reliability.
Solution Approach 2:
The channel member serves multiple functions simultaneously: it attaches to the ceiling frame via the flange, supports the bracket member, and provides a mounting surface for the system. This multi-functionality reduces the number of separate components needed, simplifying installation while ensuring reliable performance under extreme conditions.
3Ease of operation
If traditional fastening methods are used, then ease of installation is improved, but resistance to movement during high vibratory loads deteriorates
Solution Approach 1:
The channel member features a curved, U-shaped cross-section that conforms to the rectangular profile of the ceiling frame flange. This curved geometry provides continuous contact along the inner surfaces of the U-shape, creating friction-based resistance to movement while allowing simple slide-on installation. The curved profile distributes vibratory loads more effectively than sharp corners would.
Solution Approach 2:
The channel member and bracket member are formed as thin-walled metallic structures that provide flexibility while maintaining strength. This thin-walled construction allows the components to slightly deform under load, absorbing vibratory energy, while the overall geometry maintains rigid attachment to prevent movement during high-vibration events.

AI summary
A support assembly comprises a hub slidably coupled to a crossbar to support a sprinkler. A pair of opposed clip assemblies comprising a frame and a bracket couple the crossbar to the ceiling channel on either side. The frame comprises an opening that supports one end of the crossbar, a skirt with an elongated slot, and a leg that extends over the channel. The bracket couples to the frame to lock the clip assembly on the ceiling channel. The bracket comprises a ridge at one edge and a flange at an opposite edge. The ridge is configured to couple to a sidewall of the ceiling channel, and the flange is configured for a user to compress and tighten the bracket. A pair of opposing clamps on either side of the bracket ensures that the frame is securely coupled to the ceiling channel.
