Vehicle Door Weatherstrip and Garnish Assembly for Interior Styling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle door assemblies are limited by wheel well packaging constraints, which restrict the size and shape of the windowpane and create aesthetic inconsistencies between interior and exterior styling around windows.
Innovation Solution
A weatherstrip and garnish assembly is designed with a curved portion and a sunshade garnish that creates a gap, covered by a weatherstrip garnish, connected via first and second connectors, allowing the door lining to extend across and behind the windowpane, diverging from the exterior border.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the door lining follows the exterior styling feature border, then the weather sealing and structural integration are maintained, but the interior styling flexibility is limited and aesthetic consistency with wheel well cannot be achieved
Solution Approach 1:
The door assembly is divided into distinct functional segments: the door lining that follows the exterior border for weather sealing, and the door sash that extends behind the windowpane for interior styling. This segmentation allows each component to fulfill its specific function independently, resolving the contradiction between maintaining structural integrity and achieving interior design flexibility.
Solution Approach 2:
The door sash extends in the depth dimension behind the windowpane, creating a three-dimensional styling feature that diverges from the two-dimensional exterior border. This dimensional extension allows the interior styling to differ from exterior styling while maintaining proper weather sealing at the border interface.
2Adaptability or versatility
If the door sash extends behind the windowpane for interior styling, then interior aesthetic flexibility is improved, but the packaging constraint from wheel well and structural integration are worsened
Solution Approach 1:
The door sash extension behind the windowpane is implemented only in the interior styling region where aesthetic flexibility is desired, while the exterior border region maintains its traditional follow-the-window configuration for proper weather sealing. This localized application of the extension resolves the contradiction by applying the styling feature only where it provides benefit without compromising structural constraints.
3Adaptability or versatility
If multiple separate components (weatherstrip, sunshade garnish, weatherstrip garnish) are used, then aesthetic customization and styling flexibility are improved, but the manufacturing complexity and assembly steps increase
Solution Approach 1:
The garnish assembly is segmented into distinct components (sunshade garnish, weatherstrip garnish, connectors) that can be manufactured independently using different materials and processes optimized for each component's specific requirements, then assembled through standardized connection interfaces.
Solution Approach 2:
The weatherstrip garnish serves as an intermediary component that bridges the sunshade garnish and the weatherstrip assembly, providing a standardized interface for connection while allowing aesthetic customization. This intermediary component simplifies the overall assembly process by creating modular connection points.

AI summary
Some embodiments are directed to a weatherstrip and garnish assembly for use with a vehicle door that includes a body flange. The weatherstrip and garnish assembly can include a weatherstrip assembly that has a weatherstrip configured to be secured to the body flange of the vehicle door. The weatherstrip can include a curved portion. A sunshade garnish can be spaced from the curved portion of the weatherstrip to define a gap therebetween. A weatherstrip garnish can be disposed between the sunshade garnish and the weatherstrip so as to cover the gap. A first connector can connect the sunshade garnish to the weatherstrip garnish. A second connector can connect the weatherstrip garnish to the weatherstrip assembly.
