Vehicle Interior Clip Mount Segmented Board Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle interior components, such as door trims, are prone to deformation and cracking during side collisions due to the lack of support for clip mounts, which affects their shock-absorbing performance and occupant protection.
Innovation Solution
A vehicle interior component design featuring a first board, a second board, and a clip mount portion where the clip mount is integrated into the second board, with extending portions fixed to the flange portion of the first board, providing support and reducing the likelihood of cracking while enhancing shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the clip mount legs are not supported by the flat portion to allow deformation and shock absorption, then shock absorbing performance is improved, but the legs are coupled with the raised wall causing stress concentration at boundaries which may cause cracks in the design surface
Solution Approach 1:
The vehicle interior component is divided into multiple boards (first board, second board, third board) with the clip mount portion integrated into the second board. The extending portions fixed to the flange portion of the first board create a segmented support structure that distributes stress away from the design surface, allowing the clip mount legs to deform for shock absorption without causing cracks in the design portion.
Solution Approach 2:
The extending portions act as intermediary elements between the clip mount portion and the first board. These extending portions are fixed to the flange portion of the first board, providing indirect support that allows the clip mount legs to function as shock absorbers while preventing direct stress transmission to the design surface that would cause cracking.

AI summary
A vehicle interior component includes a first board and a second board assembled together. The first board includes a design portion, a peripheral wall portion, and a flange portion. The second board includes a main wall portion and a clip mount portion. The clip mount portion includes an extending portion, a mount base, and at least one leg. The extending portion extends from an edge of the second board toward the first board and is fixed to the flange portion of the first board. The mount base is disposed parallel to and away from a back surface of the design portion and coupled with the extending portion. The at least one leg protrudes from the mount base toward the back surface of the design portion with a clearance between the at least one leg and the peripheral wall portion. The at least one leg is coupled with the extending portion.
