Vehicle Trim Shell Structure for Seamless Gap Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle trim assemblies fail to effectively obscure gaps and seams between trim panels, resulting in a non-seamless appearance from within the vehicle cabin, and lack flexibility for easy installation and maintenance.
Innovation Solution
A trim assembly featuring a shell that couples with trim panels, extending across gaps and seams, and includes a flexible and rigid design with connector portions and a skin for aesthetic and tactile appeal, allowing deformation for easier installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If trim panels are separated by gaps for structural reasons, then structural integrity is maintained, but aesthetic appearance deteriorates due to visible gaps and seams
Solution Approach 1:
A shell acts as an intermediary component that couples with multiple trim panels and extends across the gaps between them. The shell's outer surface is continuous and obscures the gaps from view, creating a seamless appearance while allowing the trim panels to remain structurally separated.
2Stability of the object's composition
If trim assembly is made rigid for structural stability, then stability is improved, but ease of installation deteriorates due to inability to deform for fitting
Solution Approach 1:
The shell is divided into multiple shell portions that are separately formable and then coupled together. This segmentation allows each portion to be independently formed and positioned, facilitating easier installation while maintaining structural stability when assembled.
Solution Approach 2:
The shell includes weakened portions that allow it to deform in response to forces during installation. This temporary deformation capability enables the rigid shell to be fitted into place, after which it maintains its structural stability.
3Ease of operation
If shell is made flexible for easy installation, then ease of installation is improved, but structural strength deteriorates
Solution Approach 1:
The shell has different properties in different regions: weakened portions that allow deformation for installation, and stronger portions that provide structural support when assembled. This local differentiation of properties enables both easy installation and structural strength.
4Area of stationary object
If multiple trim panels are used to cover structural portions, then coverage is improved, but visibility of gaps between panels worsens
Solution Approach 1:
The shell merges the appearance of multiple trim panels by providing a continuous outer surface that extends across the gaps between panels. This visual merging obscures the gaps from view while the trim panels maintain their separate structural functions.

Function Achieved in This Case
The solution provides a seamless appearance by obscuring gaps and seams, facilitates easy assembly and maintenance, and offers flexibility for maneuverability and personalization of the vehicle interior.
Implementation Method 1
the shell has a weakened portion that separates a first shell portion from a second shell portion and is configured to allow the shell to deform in response to a force

AI summary
A trim assembly has a trim portion that includes a first trim panel and a second trim panel that are separated by a gap. A shell is configured to couple with the trim portion, and an outer surface of the shell is continuous from an outer edge of the first trim panel to an outer edge of the second trim panel and extends across the gap.
