Vehicle Trim Panel for Floating Roof Appearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle body structures lack an effective solution to create a floating roof appearance by integrating exterior trim panels seamlessly with the rear pillar structure, which affects the aesthetic appeal and design consistency.
Innovation Solution
The integration of an exterior trim panel that extends from the rear side window along the vehicle body waistline to the rear window, featuring a contoured design with snap-fitting projections and alignment pins, which overlays the recessed areas of the rear pillar portion, creating a cohesive and visually floating roof effect.

Engineering Contradiction Analysis
1Shape
If an exterior trim panel is installed along the rear pillar portion to create a floating roof appearance, then the aesthetic appeal and visual effect are improved, but the structural complexity and manufacturing difficulty increase
Solution Approach 1:
The exterior trim panel is divided into multiple sections: a first section extending rearward from the front peripheral edge section along the outboard facing surface, and a second section extending inboard from the rearward end of the first section to the inboard peripheral edge section. This segmentation allows each section to be independently formed and attached to different surfaces of the rear pillar portion, simplifying the overall integration process while achieving the desired floating roof appearance.
Solution Approach 2:
The exterior trim panel is installed within a recess formed in the rear pillar portion, with the trim panel effectively nested inside this recessed area. The first section overlays the outboard facing surface while the second section overlays the rearward facing surface, creating a layered integration that simplifies the external appearance while managing structural complexity internally.

If the trim panel extends along the vehicle body waistline from the rear side window to the rear window, then the visual continuity and aesthetic appeal are improved, but the manufacturing precision requirements increase
Solution Approach 1:
The exterior trim panel features different configurations for different sections: the first section is designed to extend along the outboard facing surface at the vehicle body waistline, while the second section is designed to extend to the rear window opening. Each section can be independently formed with specific contours and attachment features, allowing local optimization of manufacturing processes while maintaining overall visual continuity.
Solution Approach 2:
The recess is pre-formed in the rear pillar portion before the exterior trim panel is installed. This preliminary action provides a predetermined guide structure that ensures proper alignment and positioning of the trim panel sections, reducing the precision requirements during the final assembly process while maintaining the desired visual continuity along the vehicle body waistline.

AI summary
A rear body panel has a pillar portion extending upward from a vehicle body waistline defined along the rear body panel. An outboard facing surface of the pillar portion has a front peripheral edge section at least partially defining a side opening. A rearward facing surface of the pillar portion has an inboard peripheral edge section partially defining a rear window opening. The rear window glass is installed within the rear window opening overlaying at least a portion of the inboard peripheral edge. A first section of the exterior trim panel extends rearward from the front peripheral edge section along the outboard facing surface at the vehicle body waistline. A second section extends in a lateral inboard direction from a rearward end of the first section to the inboard peripheral edge section along the rearward facing surface to the rear window opening at the vehicle body waistline.
