Vehicular Rear Window Assembly Integrated Spoiler Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rear slider window assemblies for vehicles require separate installation of lighting devices, such as center high-mounted stop lamps and truck bed illumination systems, which increases complexity and labor in assembly, and can lead to leak paths between the lamp and the vehicle sheet metal.
Innovation Solution
A rear window assembly with an integrated spoiler that houses a lighting device, including LEDs or other light sources, which is attached directly to the window panel as a unit, providing lighting functions like brake lights, truck bed illumination, and interior cabin lighting, and optionally includes a camera for monitoring, all electrically connected during installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate lighting devices are installed on the vehicle sheet metal above the window assembly, then lighting functions (CHMSL, truck bed illumination, interior cabin illumination) are provided, but assembly complexity and labor increase, and leak paths are created between the lamp and vehicle sheet metal
Solution Approach 1:
The patent combines the lighting device with the spoiler and window assembly into a single integrated unit. The lighting device is mounted within the spoiler structure, which is itself attached to the window panel, creating a unified assembly that eliminates the need for separate lighting device installation on the vehicle sheet metal. This merging reduces the number of discrete components and simplifies the overall assembly process while maintaining all required lighting functions.
2Productivity
If separate lighting devices are installed on the vehicle sheet metal, then lighting functions are provided, but installation labor and complexity increase
Solution Approach 1:
The lighting device is integrated with the spoiler and window assembly as a single unit, allowing all components to be installed together in one operation. This eliminates the need for separate installation steps for lighting devices, thereby reducing installation labor time and improving productivity during vehicle assembly.
3Reliability
If separate lighting devices are mounted on vehicle sheet metal, then lighting functions are achieved, but leak paths are created between the lamp and sheet metal
Solution Approach 1:
The lighting device is mounted within the spoiler structure that is attached to the window panel, creating an integrated assembly. This integration eliminates the gap or interface between the lighting device and vehicle sheet metal that would otherwise create leak paths. The unified structure provides better seal integrity and prevents water or air infiltration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution simplifies the assembly process by integrating lighting and camera functions within the window assembly, reducing labor and eliminating separate lamp installations, while minimizing leak paths and providing comprehensive lighting and monitoring capabilities.
Implementation Method 1
A lighting device having one or more strips or rows of light sources, such as a plurality of light emitting diodes (LEDs), disposed within a spoiler

AI summary
A vehicular rear window assembly includes a window panel comprising an inner side and an outer side. A spoiler includes (i) a base portion that is adhesively attached at and along an upper region of the outer side of the window panel and (ii) a cover portion that is attached at the base portion. The vehicular rear window assembly, with the spoiler adhesively attached at and along the upper region of the outer side of the window panel, is configured for mounting at a rear portion of a cabin of the vehicle. With the vehicular rear window assembly mounted at the rear portion of the cabin of the vehicle, the inner side is toward the cabin of the vehicle and the outer side and the spoiler are exterior of the vehicle.
