Motor Vehicle Side Wall Cladding Element Non-Destructive Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for attaching side wall cladding elements to motor vehicle interior walls require irreversible intervention in the vehicle body, causing damage and compromising anti-corrosion protection.
Innovation Solution
A side wall cladding element with a materially bonded coupling body that uses spacer elements and connecting sections for secure attachment without drilling, allowing for non-destructive installation and adjustable positioning relative to the vehicle's inner wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fastening screws are used to attach side wall cladding elements to the motor vehicle inner wall, then secure attachment is achieved, but the vehicle body is damaged and anti-corrosion protection is compromised
Solution Approach 1:
A coupling body is introduced as an intermediary component between the base body and the motor vehicle inner wall. The coupling body includes a connecting element for material-bonded attachment to the inner wall and spacer elements that provide spacing. This intermediary structure enables secure attachment without direct penetration of the vehicle body, thus maintaining anti-corrosion protection while achieving strong fixation.
Solution Approach 2:
The invention replaces the mechanical fastening system (screws penetrating the body) with a material-bonded attachment system. The connecting element of the coupling body is designed for material-bonded attachment to the inner wall, eliminating the need for drilling holes or inserting fasteners that would damage the body and compromise its protective coating.
2Object-affected harmful factors
If the coupling body uses material-bonded attachment, then non-destructive installation is achieved, but the attachment strength may be reduced
Solution Approach 1:
The coupling body merges multiple functions into a single integrated component: the connecting element provides material-bonded attachment to the inner wall, while spacer elements provide spacing and positioning. This combination allows the coupling body to achieve both non-destructive installation and sufficient attachment strength through the integrated design of bonding surfaces and structural support.
