Inclined Bumper Trim Clips for Small-Profile Snap-Fit Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for standard bumper trims are incompatible with smaller trims due to profile and dimension mismatches, making it difficult to attach and secure smaller bumper trims on motor vehicles.
Innovation Solution
The use of fastening clips with an inclined conformation relative to the bumper trim's elongation axis, combined with guide bearings and reception sites featuring deformable depressions, allows for snap-fit attachment and secure mounting of smaller bumper trims without the ability to be easily removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard mounting clips with dimensions exceeding 20 mm are used, then large bumper trims can be securely fastened, but smaller bumper trims cannot be properly attached due to profile and dimension incompatibility
Solution Approach 1:
The mounting clips are designed with an inclined conformation where the fastening surface is angled relative to the elongation axis of the bumper trim. This parameter change in the clip's geometry allows the same clip design to accommodate various trim sizes by adapting to different mounting surfaces, thereby improving versatility without increasing device complexity
Solution Approach 2:
The mounting clips feature an asymmetric inclined surface that allows them to engage with the bumper trim at an angle. This asymmetric design enables the clips to work with trims of different dimensions by orienting the inclined surface appropriately, resolving the contradiction between adaptability and device complexity
2Adaptability or versatility
If smaller bumper trims are used to meet evolving automotive needs, then vehicle design flexibility improves, but existing fastening devices become incompatible due to profile mismatches
Solution Approach 1:
The inclined conformation of the mounting clips changes the engagement parameters to accommodate smaller trim profiles. The angle of inclination allows the clips to bridge the gap between standard clip dimensions and smaller trim features, maintaining ease of attachment while improving compatibility
Solution Approach 2:
The inclined surface of the mounting clip acts as an intermediary element that mediates between the standard clip structure and the varied trim profiles. This intermediate inclined surface allows smooth engagement with different trim sizes, making the attachment process equally easy for both small and large trims
3Reliability
If deformable depressions with concave surfaces are used in reception sites, then secure non-removable fixing is achieved, but the mounting space requirements increase
Solution Approach 1:
The deformable depressions feature concave curved surfaces that concentrate the fastening force along the inclined axis of the mounting clip. This curvature allows the clips to engage deeply and securely in a compact space, achieving reliable non-removable fixing without requiring excessive mounting area
Solution Approach 2:
The mounting clip structure is designed to nest into the deformable depression, with the inclined surface fitting into the concave shape. This nested configuration maximizes the securing effect within minimal space, resolving the contradiction between fixing reliability and space requirements

AI summary
The invention relates to a bumper trim (1) for a motor vehicle, the bumper trim (1) extending along its own elongation axis (O1) and comprising, on one rear face, a plurality of fastening clips (12, 12A) designed to interact with additional openings provided on a mounting site (3) for a bumper skin of the motor vehicle. Each fastening clip (12, 12A) has an inclined orientation with respect to the own elongation axis (O1), and each fastening clip (12, 12A) is contained within the width of one body of the bumper trim (1). Each fixing clip (12, 12A) is configured to collaborate with an opening (33) provided at one end of a concave surface (32) forming the receiving site (3), the fixing clip (12, 12A) being forcibly engaged in the opening (33) without being able to be retracted afterwards.
