Vehicle Door Lining Assembly with Oblique Base Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle door interior surfaces face challenges in balancing aesthetics and functionality, requiring resilience to both extreme exterior conditions and less extreme interior conditions, while also providing support for passenger controls and direct contact, necessitating a configuration that enhances visual and operational interaction with other surfaces.
Innovation Solution
A door lining assembly with an outboard base oriented obliquely upward and an inboard base oriented downward, joined to form a peak, covered by a unitary topcoat, which enhances aesthetics and functionality by providing a uniform appearance and functional integration with the door assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the interior surface is configured to provide support for passenger controls and direct contact, then functionality is improved, but aesthetic appearance may deteriorate due to the need for additional functional elements
Solution Approach 1:
The patent merges the arm rest and door control panel into a single integrated door lining assembly. The control panel is embedded within the arm rest structure, allowing both functions (passenger contact/support and control operation) to coexist in a unified design that maintains aesthetic appearance while providing necessary functionality.
Solution Approach 2:
The door lining assembly is designed to perform multiple functions simultaneously: it serves as an arm rest for passenger support, a control panel for door operations, and an aesthetic interior surface. This multi-functional design resolves the contradiction by making the same structure serve both functional and aesthetic purposes.
2Shape
If the interior surface is configured to enhance aesthetics through specific orientations and visual interactions, then aesthetic appearance is improved, but structural complexity increases
Solution Approach 1:
The door lining assembly is segmented into distinct functional zones: an outboard base portion facing the exterior and an inboard base portion facing the interior passenger compartment. This segmentation allows each portion to be optimized for its specific function while maintaining overall aesthetic coherence through the unified assembly design.
Solution Approach 2:
The patent employs asymmetric orientation of the base portions, with the outboard base oriented at a first angle relative to the transverse direction and the inboard base oriented at a second angle. This asymmetric configuration enhances aesthetic appearance by creating visual interest and complementing other interior surfaces, while the angles are carefully chosen to maintain structural integrity.
3Shape
If a common exterior layer is applied to cover both outboard and inboard bases, then aesthetic appearance is improved through uniform appearance, but manufacturing complexity increases
Solution Approach 1:
A single unitary topcoat is applied to cover both the outboard and inboard bases, creating a uniform and smooth appearance across the entire door lining assembly. This merging of the coating process into one operation simplifies manufacturing compared to applying separate coatings to each base portion, while still achieving the desired aesthetic uniformity.
Solution Approach 2:
The unitary topcoat provides a homogeneous exterior surface that unifies the appearance of the door lining assembly. This homogeneous coating layer ensures consistent aesthetic appearance across different portions of the assembly while being applied as a single material layer, thereby reducing manufacturing complexity.

AI summary
Some embodiments are directed to a door lining assembly for use with a vehicle that defines a vehicle exterior and a vehicle passenger compartment. The door lining assembly can include a base assembly including an outboard base that defines a substantially planar upper surface that extends obliquely relative to a transverse direction of the vehicle so as to face upwardly toward the vehicle exterior. The base assembly can also include an inboard base that defines a substantially planar upper surface that extends obliquely relative to the upper surface of the outboard base downward toward the vehicle passenger compartment. The outboard and inboard bases can be joined together to form a peak that is the vertically highest portion of the base assembly. A unitary topcoat can cover the upper surfaces of the outboard and inboard bases.
