Deflection Clip With Triangular Barbs For Metal Stud Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deflection clips in interior construction require temporary fastening to the ceiling track, which is time-consuming and labor-intensive, and can cause drywall damage, as they need to be screwed in and then removed before installing wallboard.
Innovation Solution
A deflection clip with a flat, rectangular base and perpendicular extensions featuring triangular barbs that secure the stud without needing temporary attachment to the ceiling track, allowing the clip and track to slide with vertical loads, eliminating the need for fasteners and reducing labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If deflection clips are temporarily fastened to the ceiling track with screws, then the stud is securely attached during installation, but the process becomes time-consuming and labor-intensive requiring screw removal before drywall installation
Solution Approach 1:
The patent removes the temporary fastening step by extracting the screw attachment mechanism and replacing it with a permanent deformable barb design that provides secure attachment without requiring subsequent removal, thus eliminating the time-consuming fastener installation and removal process
Solution Approach 2:
The deformable barbs are pre-formed on the deflection clip during manufacturing, allowing the clip to be directly tapped into the stud channel without requiring现场 fastening operations, thereby performing the attachment function in advance through pre-formed structural features
2Reliability
If deflection clips are screwed to the ceiling track, then secure attachment is achieved, but drywall damage occurs due to screw attachments transferring to the stud
Solution Approach 1:
The patent eliminates the screw fastening mechanism entirely, replacing it with deformable barbs that provide secure attachment without creating screw holes or attachment points that could transfer stress to the drywall, thus removing the source of potential drywall damage
Solution Approach 2:
The deformable barbs are designed as a single-use, non-removable attachment mechanism that provides permanent secure fixation without the need for reversible fasteners, eliminating the cycle of attachment and detachment that causes drywall damage
3Reliability
If traditional deflection clips are used requiring fastener installation and removal, then secure attachment is achieved during installation, but labor costs increase due to the additional steps
Solution Approach 1:
The patent removes the fastener installation and removal steps from the installation process by extracting the screw mechanism and replacing it with a direct tap-in deformable barb design, thereby eliminating unnecessary labor steps and improving installation efficiency
Solution Approach 2:
The deformable barbs are designed to self-engage with the stud channel when the clip is tapped into place, providing automatic secure attachment without requiring manual fastening operations, thus making the attachment process self-service and labor-efficient
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
The solution reduces labor and prevents drywall damage by allowing the deflection clip to be tapped into place without screws, enabling efficient installation and sliding functionality under vertical loads without transferring loads to the stud.
Implementation Method 1
Each flange contains at least one substantially triangular shaped barb cut from the flange. Each barb extends outward by leaving the superior portion of the barb connected to the flange. The deflection clip secures the stud positioned between the open channel tracks which are affixed to the floor and ceiling.
Implementation Method 2
The deflection clip and top track can then slide on the stud as required due to changes in vertical loads.

AI summary
An improved deflection clip for connecting metal stud walls to a structural building member, which accommodates relative compensating vertical movement, is disclosed. Some embodiments of the present invention allow for the deflection mounting clip to be set into place by metal barbs, eliminating the need for screwing the stud to the ceiling track runner, then subsequently removing the screws when the wallboard is installed. A deflection clip in accordance with the present invention has a flat base with left and right flanges substantially perpendicular to the base. Each flange has a number of triangular barbs facing externally to secure the deflection clip to the track without the need for temporary fixation.
