Vehicle Interior Cover Mount Assembly with Elastic Clip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interior cover mount assemblies for vehicle components, such as door grips, are inefficient to mount and prone to detachment due to holding forces or shocks, particularly in collisions.
Innovation Solution
An interior cover mount assembly featuring a tether clip with an arm section and a head section that elastically deforms and fits into an insertion stopper hole, ensuring secure attachment to the base member with reduced detachment risk, and simplifying the mounting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tether clip is mounted on the back surface of the interior cover and fixed to the base member before mounting, then the interior cover is less likely to be detached from the base member, but the work efficiency of mounting the interior cover is reduced
Solution Approach 1:
The clip is pre-installed on the interior cover before assembly, with the arm section extending toward the base member. The head section is positioned to be inserted into the insertion stopper hole during the final assembly operation, eliminating the need for separate pre-mounting of the tether clip to the base member
Solution Approach 2:
The mounting operation combines two actions into one: inserting the head section of the clip into the insertion stopper hole and simultaneously securing the interior cover to the base member. This integrated operation eliminates separate mounting steps and improves work efficiency
2Reliability
If the distal end portion of the tether clip is held on the base member before mounting the interior cover, then the interior cover is secured to the base member, but the mounting operation becomes more complex and time-consuming
Solution Approach 1:
The clip is pre-installed on the interior cover with the arm section extending toward the base member and the head section positioned for insertion. This preliminary positioning eliminates the need for separate pre-mounting operations and simplifies the final assembly to a single insertion motion
Solution Approach 2:
The function of securing the interior cover to the base member is extracted from a separate pre-mounting operation and integrated into the final assembly operation. The head section insertion simultaneously achieves both clip fixation and interior cover attachment, reducing operational complexity
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 solution provides an easy and secure mounting operation for interior covers, reducing the likelihood of detachment from the base member and enhancing work efficiency, even under collision conditions.
Implementation Method 1
The clip is elastically deformed toward the insertion section by contact with the projection according to movement of the interior cover toward the base member in the mounting direction

AI summary
An interior cover mount assembly includes a base member and an interior cover including a clip and the clip includes an arm section and a head section having a width greater than that of the arm section. The base member has an insertion stopper hole through which the head section is inserted and a projection projecting from the base member toward the interior cover and disposed near the holding section. The insertion stopper hole includes an insertion section through which the head section is inserted and a holding section having a width smaller than that of the head section and greater than that of the arm section and where the arm section is arranged. In the interior cover that is mounted on the base member, the clip is fit in the insertion stopper hole such that the head section overlaps the holding section and the projection in the mounting direction.
