Vehicle Door End Cap Gap Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door assemblies face challenges in sealing gaps between components, which can lead to water intrusion and compromised appearance quality due to exposed edges and lack of effective gap filling solutions.
Innovation Solution
A vehicle door assembly design incorporating a first and second molding, with an end cap that extends across the gap between these moldings to fill and cover the space, enhancing sealing and aesthetic appeal by attaching to both moldings and using adhesives for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If moldings are installed to door components to cover and enhance appearance, then appearance quality is improved, but gaps between moldings are exposed and vulnerable to water intrusion
Solution Approach 1:
An end cap is introduced as an intermediary component between the first molding and second molding. The end cap fills the gap between these moldings, preventing water intrusion while maintaining the aesthetic appearance. The extension of the end cap across the gap creates a seamless visual appearance, and the adhesive attachment secures the assembly against water penetration.
2Shape
If moldings are installed to cover door components, then appearance quality is improved, but gap sealing and structural integrity are compromised
Solution Approach 1:
The end cap serves as a mediator that bridges the gap between moldings, providing both aesthetic coverage and reliable sealing. By positioning the end cap to extend across the gap and attaching it with adhesive, the system achieves both appearance quality and gap sealing reliability simultaneously.
3Object-affected harmful factors
If traditional gap filling solutions are used, then gap coverage is achieved, but appearance quality and structural integrity are compromised
Solution Approach 1:
Rather than using traditional gap filling materials that may compromise appearance, the patent uses an end cap as an intermediary component. This end cap is specifically designed to extend across the gap, providing coverage while maintaining a clean, seamless appearance that enhances rather than compromises the aesthetic quality of the door assembly.
4Device complexity
If moldings are installed without end cap support, then assembly simplicity is maintained, but structural integrity and component support are insufficient
Solution Approach 1:
The end cap acts as a structural intermediary that supports the first molding to the second molding. This intermediate component provides the necessary structural integrity and component support while being integrated into the existing molding assembly, maintaining relative simplicity in the overall assembly process.

AI summary
A vehicle door assembly includes a first molding, a second molding and an end cap. The first molding is configured to be installed to a first door component. The second molding is configured to be installed to a second door component. The first and second moldings at least partially define a vehicle window opening. The end cap supports an end of the first molding to an end of the second molding. The end cap has an extension extending across a gap at least partially defined by the first and second moldings to fill the gap.
