Cargo Vehicle Molding Assembly with Integrated Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cargo vehicles, especially those with large or complex internal structures, often face inadequate lighting in areas away from direct light sources due to internal obstructions, such as movable partitions or elongated designs, which limits illumination in cargo compartments.
Innovation Solution
A molding assembly with a back portion and a cover portion is strategically placed at intersections within the cargo compartment, where the cover portion includes a light source to ensure uniform lighting across the compartment, using elongated webs and retention flanges for secure attachment and sealing to prevent air leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If intermittent lighting fixtures are used in cargo vehicles, then the lighting system is simpler and more cost-effective, but the illumination uniformity and coverage in large or complexly structured cargo compartments deteriorates
Solution Approach 1:
The lighting system is segmented into multiple independent lighting assemblies distributed throughout the cargo compartment. Each assembly includes a light source, housing, and mounting structure that can be independently positioned to address specific lighting needs in different zones, ensuring uniform illumination without requiring a single complex centralized system
Solution Approach 2:
Lighting assemblies are strategically positioned at locations providing optimal local illumination coverage. The system allows different lighting characteristics and intensities in different zones of the cargo compartment, with each lighting assembly tailored to illuminate specific areas effectively while maintaining overall uniformity
2Ease of manufacture
If lighting fixtures are mounted at standard locations, then the installation process is simpler and faster, but the lighting coverage in areas with internal obstructions such as movable partitions deteriorates
Solution Approach 1:
The lighting assembly incorporates movable or adjustable mounting mechanisms that allow repositioning of light sources to overcome obstructions. The assembly can be dynamically adjusted during installation and operation to optimize lighting coverage in areas with movable partitions or other internal obstructions while maintaining simple installation procedures
Solution Approach 2:
The lighting assembly utilizes three-dimensional positioning and angular adjustment capabilities to illuminate areas blocked by obstructions. By changing the spatial dimension and angle of light projection, the system achieves comprehensive coverage without requiring complex installation procedures at non-standard locations
3Illumination intensity
If elongated molding assemblies are used to provide comprehensive lighting coverage, then the illumination uniformity improves, but the device complexity and number of components increases
Solution Approach 1:
Multiple lighting functions and components are merged into single integrated lighting assemblies. Each assembly combines light sources, housing, mounting structures, and adjustment mechanisms into one unified component, reducing the total number of separate parts while maintaining comprehensive lighting coverage and uniformity throughout the cargo compartment

AI summary
A cargo compartment for use with a motorized vehicle, and a vehicle having a cargo compartment, have a floor, a roof, a first side wall, and a second side wall. Each side wall extends between the floor and the roof, defining intersections therebetween. A molding assembly is disposed in the intersection and has an elongated back portion and an elongated cover portion, so that the cover portion is disposed between the back portion and an interior cargo compartment.
