Rear Slider Window Assembly with Integrated Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rear slider window assemblies for vehicles lack integrated lighting solutions that provide both functional illumination and a flush glass appearance, often requiring separate assemblies and complex installations.
Innovation Solution
A rear slider window assembly with a lighting device comprising one or more strips of light sources, such as LEDs, disposed behind the fixed glass window panel, which can be electrically connected to the vehicle's wiring harness to provide both brake light and truck bed illumination functions, eliminating the need for external lamps and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate external lamps and lighting assemblies are used, then lighting functionality is achieved, but assembly complexity increases and flush glass appearance is compromised
Solution Approach 1:
The patent combines the lighting device with the fixed window panel into a single integrated assembly. The light sources are mounted on the interior surface of the fixed window panel, merging two separate components (lighting device and window panel) into one unified structure that simplifies assembly and reduces the number of parts required.
Solution Approach 2:
The fixed window panel serves multiple functions: it acts as both the structural window component and the mounting substrate for the lighting device. This multi-functional design eliminates the need for separate mounting brackets or housing structures, thereby reducing assembly complexity.
2Length of moving object
If external lamps are mounted on the vehicle body, then lighting function is provided, but the window roofline height is reduced and appearance is compromised
Solution Approach 1:
The lighting device is nested within the window assembly structure, specifically mounted on the interior surface of the fixed window panel. This nesting approach allows the lighting function to be incorporated without adding external protrusions that would reduce the window roofline height or compromise the vehicle's aesthetic appearance.
3Reliability
If separate lighting assemblies are installed, then lighting functionality is achieved, but leak paths are created and reliability is reduced
Solution Approach 1:
By merging the lighting device with the fixed window panel into a single integrated assembly, the patent eliminates the interfaces and joints between separate components that would otherwise create potential leak paths. The integrated design ensures a sealed construction that improves reliability.
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
The solution offers a flush glass appearance with integrated lighting, reducing assembly complexity, increasing window roofline height, and extending the life cycle of rear lights, while eliminating leak paths and simplifying the installation process.
Implementation Method 1
a lighting device having one or more strips or rows of light sources disposed behind the fixed glass window panel

AI summary
A rear window assembly for a vehicle includes a fixed window panel. The rear window assembly may be a rear slider window assembly, with the fixed window panel fixed relative to a frame portion and defining an opening, and with a movable window panel movable along the frame portion between a closed position and an opened position. A lighting device is disposed at an inner surface of the fixed window panel and includes an interior lighting element that is operable to emit light that passes through a light transmissive portion of a housing of the lighting device so as to illuminate an interior cabin of the vehicle. The lighting device may also include an exterior lighting element that is operable to emit light that passes through the fixed window panel so as to be viewable by a person viewing the slider window assembly from exterior and rearward of the vehicle.
