Vehicle Interior Mounting Bracket Guiding Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mounting structures for vehicular interior parts with air bag components require excessive force for installation, leading to stress concentration, texture deterioration, and increased operational time due to the resistance of flexible portions against the interior part surfaces.
Innovation Solution
A mounting device with a flexible portion and a guiding portion within the mounting bracket, where the flexible portion is inclined and biased by the guiding portion, reducing the pressing force against the interior part surface and preventing texture deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flexible portion of the mounting device is made longer to ensure proper engagement, then the engagement reliability is improved, but the resistance against the interior part surface increases causing texture deterioration
Solution Approach 1:
The guiding portion acts as an intermediary element between the flexible portion and the interior part surface. It provides a dedicated contact surface that directs the flexible portion's movement, preventing direct contact with and damage to the interior part's textured surface while maintaining proper engagement
2Reliability
If excessive force is applied during installation to ensure proper mounting, then the mounting reliability is improved, but the texture deterioration and stress concentration increase
Solution Approach 1:
The guiding portion serves as a mediator that distributes and directs the installation force along a controlled path. It allows the flexible portion to engage properly with minimal force by providing mechanical guidance, preventing stress concentration and texture deterioration on the interior part surface
3Device complexity
If the flexible portion is inserted directly without guidance, then the device complexity is reduced, but the installation difficulty increases due to misalignment and excessive force requirements
Solution Approach 1:
The guiding portion is pre-formed as an integral part of the mounting bracket structure. It provides preliminary alignment and direction for the flexible portion before engagement, eliminating the need for complex alignment procedures during installation while maintaining structural simplicity
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
Facilitates easy installation of vehicular interior parts by reducing the force required and preventing texture deterioration, maintaining the appearance and functionality of the parts.
Implementation Method 1
a flexible portion 46, with a total length L (see FIG. 16(a)), which is formed on the other side of the flange portion 42 so as to be longer than the protrusion height H of the mounting bracket 32

AI summary
Interior parts for vehicles such as a front pillar garnish having a mounting bracket 32 to which a mounting clip 40 is connected so that the front pillar garnish is mounted to a front pillar. The mounting bracket 32 is formed on the inner side (that faces the front pillar) of the garnish main body 30 and has an inclined guiding portion 70 in its accommodating space 36 so that the flexible portion 46 of the mounting clip 40 inserted into the accommodating space 36 is bent inside the mounting bracket 32 by the inclined guiding portion 70, and the second engaging portion 50 at the distal end of the flexible portion 46 is prevented from contacting the garnish main body 30 by way of the opening 72 of the mounting bracket 32, thus allowing the mounting clip 40 not to be forcibly pressed against the garnish main body 30.
