Vehicle Retention Assembly With Integrated Seal for One-Sided Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing retention systems for add-on parts on motor vehicles often require complex assembly and access from the opposite side of the structural element, leading to increased production complexity and potential fluid leakage.
Innovation Solution
A retention apparatus with separate securing regions and a sealing element that allows for secure, one-sided attachment of add-on parts to the structural element, minimizing structural space and assembly complexity while maintaining fluid-tight integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing retention systems are used to attach add-on parts to structural elements, then secure attachment is achieved, but assembly complexity increases and access from the opposite side is required
Solution Approach 1:
The retention apparatus is divided into two distinct securing regions: a first securing region that attaches to the structural element and a second securing region that attaches to the add-on part. This segmentation allows the retention apparatus to be installed from one side only, eliminating the need for access to the opposite side and reducing assembly complexity while maintaining secure attachment through the distributed securing regions.
2Reliability
If existing retention systems are used to attach add-on parts to structural elements, then secure attachment is achieved, but access from the opposite side is required
Solution Approach 1:
Instead of requiring access from both sides of the structural element (conventional approach), the retention apparatus is designed to be installed from one side only. The first securing region engages with the structural element from the accessible side, and the second securing region extends to attach the add-on part, inverting the conventional assembly approach and greatly improving accessibility.
3Reliability
If complex retention systems are used to secure add-on parts, then attachment security is maintained, but production costs increase
Solution Approach 1:
The retention apparatus serves multiple functions within a single component: it provides secure attachment through two securing regions, acts as a seal between the add-on part and structural element, and enables one-sided installation. This multi-functionality eliminates the need for separate complex systems, reducing production costs while maintaining attachment security.
4Reliability
If complex retention systems are used to secure add-on parts, then attachment security is maintained, but structural space increases
Solution Approach 1:
The retention apparatus is designed with a compact structure where the second securing region is integrated into or extends from the first securing region. This nested configuration minimizes the overall volume occupied by the retention system while maintaining the dual securing regions needed for reliable attachment, thereby reducing structural space requirements.

AI summary
A retention apparatus for securing an add-on part to a component for a motor vehicle includes a first fastening region, via which the retention apparatus is to be secured to the component, a second fastening region, via which the add-on part is to be secured to the retention apparatus, and a seal element, which is connected to the first fastening region and is designed to bear against the component, and by which the retention apparatus can be sealed with respect to the component.
