Sealing Plug Profile with Segmented Baseboard for Vehicle Roof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing solutions for vehicle roof cover systems face challenges in providing a reliable and cost-effective, secure, and stable retention while sealing against environmental influences, particularly water penetration, within the constraints of automotive structural space provisions.
Innovation Solution
A sealing plug profile with a baseboard featuring a central web that separates two base hollow spaces, allowing for a force-transmitting plug-in base that simplifies assembly and reduces assembly time, and includes features like chamfered faces, wing elements, and engagement elements for secure retention without the need for adhesive bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive bonding is used to secure sealing elements to cover system components, then reliable sealing against water penetration is achieved, but assembly time increases and assembly complexity increases
Solution Approach 1:
The patent replaces adhesive bonding (chemical method) with a mechanical retention system consisting of a baseboard with retention elements that engage with corresponding features on the cover system components. This mechanical substitution eliminates the need for adhesive application and curing time while maintaining secure attachment of the sealing element
Solution Approach 2:
The sealing assembly is segmented into distinct functional components: a baseboard with retention elements for mechanical attachment, and a separate sealing element that interfaces with the cover system. This segmentation allows for simplified assembly where components can be independently manufactured and assembled in a straightforward sequence without complex bonding operations
2Reliability
If adhesive bonding is used to secure sealing elements, then reliable sealing is achieved, but assembly complexity and physical strain increase
Solution Approach 1:
The patent replaces adhesive bonding (chemical method) with a mechanical retention system consisting of a baseboard with retention elements that engage with corresponding features on the cover system components. This mechanical substitution eliminates the need for adhesive application and curing time while maintaining secure attachment of the sealing element
Solution Approach 2:
The retention elements on the baseboard are designed to automatically engage with corresponding features on the cover system components through simple insertion or snap-fit actions. The system is self-aligning and self-securing, eliminating the need for complex bonding operations, precision alignment procedures, or specialized assembly tools, thereby reducing assembly complexity and physical strain
3Reliability
If conventional sealing bases are used in automotive structural space provisions, then sealing function is achieved, but secure and stable retention becomes difficult to provide
Solution Approach 1:
The baseboard is designed with a three-dimensional structure featuring retention elements that engage with corresponding features on the cover system components in multiple directions. This multi-dimensional engagement geometry provides secure and stable retention within the constrained automotive structural space by distributing forces across multiple contact points and engagement surfaces rather than relying on a single-plane attachment

AI summary
A sealing plug profile for fitting to an arrangement for a vehicle roof has a sealing element and a baseboard which is coupled to the sealing element and which extends along a longitudinal axis (LF). The baseboard may have a first base hollow space and a second base hollow space and a central web which separates the first and the second base hollow space from each other in a predetermined manner so that the first and the second base hollow space form two mutually separate hollow spaces within the baseboard, which are each delimited in a predetermined manner along the longitudinal axis (LF) by the central web and an edge of the baseboard.
