Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing impaling clips for mounting polyester acoustic panels on structural components are prone to disengagement and twisting, necessitating the use of adhesives or alternative methods to secure the panels effectively.
Innovation Solution
The development of impaling clips with planar prongs featuring sharp main points and undercut barbs that penetrate and securely hold polyester panels, resisting extraction, combined with a base design that stabilizes the panel against pivoting or twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If prior art impaling clips with simple piercing points are used to mount polyester acoustic panels, then the clips can penetrate the panel material, but the panels become prone to disengagement and twisting
Solution Approach 1:
The piercing member is segmented into multiple discrete piercing points (at least three points) distributed across the base, rather than a single piercing element. This segmentation provides multiple anchoring locations that distribute mechanical loads and prevent rotational movement, thereby preventing panel twisting while maintaining ease of installation.
Solution Approach 2:
The piercing members are configured with specific geometric properties including acute angles (20-45 degrees) relative to the base surface and varying lengths. This local quality variation optimizes penetration effectiveness at different locations, ensuring reliable engagement with polyester panel material while preventing disengagement through strategically positioned sharp points.
2Productivity
If polyester acoustic panels are mounted using conventional impaling clips, then the mounting process can be completed, but additional adhesives are required to prevent disengagement
Solution Approach 1:
The piercing members are designed to self-grip the polyester panel material through their geometric configuration (acute angles and varying lengths). The panels themselves provide the gripping mechanism through friction and mechanical interlocking with the piercing points, eliminating the need for additional adhesives or complex fastening systems while maintaining high mounting productivity.
3Strength
If impaling clips with sufficient piercing depth are used to secure polyester panels, then the panels resist extraction, but the clips allow twisting or pivoting motion
Solution Approach 1:
By distributing at least three piercing points across the base area, the system creates multiple rotational axes that must simultaneously move for twisting to occur. This geometric distribution of piercing members provides inherent rotational stability while each individual point maintains deep penetration for extraction resistance.
Solution Approach 2:
The piercing members extend in multiple dimensions from the base surface at various angles and positions, creating a three-dimensional anchoring pattern. This multi-dimensional configuration prevents planar twisting motion while maintaining vertical penetration depth for extraction resistance.
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 impaling clips effectively secure polyester acoustic panels without disengagement, providing stability and resistance to twisting, ensuring secure mounting without the need for additional adhesives.
Implementation Method 1
The sharp main point of the prong is configured for penetration of the rear surface of the panel, whereupon the sharp main point, the at least one subsidiary point and at least a portion of the leg portion enters and is fixedly held within the material of the panel
Implementation Method 2
The at least one subsidiary point is in the form of an undercut barb having an edge extending at an acute angle with respect to a side edge of the leg portion of the prong, resisting extraction of the prong from within the material of the panel
Implementation Method 3
The first prong is in the form of a planar member lying in a first plane projecting outward perpendicularly from the front surface and located on one side of the central longitudinal axis. The second prong is in the form of a planar member lying in a second plane projecting outward perpendicularly from the front surface and located on an opposite side of the central longitudinal axis

AI summary
A precursor to form an impaling clip, and an impaling clip formed therefrom. The impaling clip is configured for mounting an acoustic panel on a structural component, e.g., a wall stud, of a building. The impaling clip includes a base member from which a pair of prongs project upward perpendicular to the plane of the base member. The base member includes at least one hole for receipt of a fastener, e.g., a screw, to fixedly secure the base member of the clip to the structural component. Each prong includes a leg portion terminating in pointed head and outwardly projecting under-cut barbs configured to pierce through the back surface of the panel to lock the prong within the panel so that it is resistant to removal.
