Polymeric Bracket Clip Asymmetry Flush Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bracket clip solutions, such as metal spring clips and plastic snap-in clips, face challenges like rattling noise due to relative movement and gradual loosening over time, and plastic clips require free space on both sides, making them unsuitable for flush mounting against bracket walls.
Innovation Solution
A polymeric snap-in bracket clip with a low profile head, wedge-shaped legs, and a single integral snap wing that secures an insert flange in transverse relation to a mounting bracket, providing a 'U' shaped profile and a finger engagement press tab for easy installation and reduced movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plastic snap-in clips with a generally 'W' shaped profile are used, then the clip can be made with good strength and resistance to loosening, but the clip requires free space on both sides making it unsuitable for flush mounting against bracket walls
Solution Approach 1:
The clip features an asymmetric design with a single snap wing extending from only one side of the base, while the opposite side remains flush against the bracket wall. This asymmetric configuration allows the clip to achieve both structural strength through the snap wing mechanism and proper flush mounting capability by eliminating the need for clearance on the mounting side.
2Strength
If metal spring clips are used, then the clip has good strength, but relative movement following assembly occurs leading to rattling noise
Solution Approach 1:
The invention transitions from metal spring clips to a polymeric material with resilient characteristics. The polymeric clip maintains sufficient strength while the material's inherent damping properties reduce vibrations and eliminate rattling noise. The resilient nature of the polymer allows for controlled deformation that prevents relative movement between components.
3Strength
If metal spring clips are used, then the clip has good initial strength, but gradual loosening occurs over time as spring action decreases
Solution Approach 1:
The invention employs a polymeric clip designed as a single-use, non-reusable component that maintains its securing function throughout the service life of the assembly. Rather than relying on reusable spring action that degrades over time, the polymeric clip is designed to be replaced if needed, ensuring long-term reliability through its disposable nature while eliminating the gradual loosening problem of metal springs.
4Ease of operation
If a low profile head design is used, then the clip can be mounted in flush relation to the bracket wall, but the clip requires a more complex structural configuration
Solution Approach 1:
The clip is segmented into distinct functional portions: a low profile head for flush mounting, a base for positioning, legs for engagement, and a single snap wing for securing. This segmentation allows each portion to be optimized for its specific function while maintaining an overall simple integrated structure that does not require complex configurations.
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 clip effectively secures the insert flange in place, reducing rattling noise and maintaining stability over time by using a resilient snap wing and tapered legs to engage the bracket surfaces, ensuring a flush and secure mounting.
Implementation Method 1
A single integral snap wing extends in angled relation away from the base on one side of clip with a free edge disposed in opposing relation below the underside of the head portion
Implementation Method 2
Each of the legs has a wedge-shaped configuration including an upper portion of uniform width adapted for disposition at the interior of the access opening and a tapered lower portion

AI summary
A snap-in clip having a low profile head and a pair of integral spaced legs extending away from the head to an insertion base. A wing element is angled upwardly away from one side of the insertion base with a free edge projecting towards the underside of the head. The clip is adapted for insertion through an access opening in an insert flange projecting through a mounting bracket to secure the insert flange in place in transverse relation to the mounting bracket.
