Louvered Vehicle Window Assembly with Molded Joining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle window assemblies for sports cars and similar vehicles often feature louvers or spaced body panels that are opaque and do not effectively integrate glass panels in a non-coplanar configuration, leading to aesthetic and structural limitations.
Innovation Solution
A vehicle window assembly comprising multiple glass panels that are louvered or offset at their perimeter edges, joined by molded encapsulation or rib portions, creating a flush and integrated appearance without overlapping the outer surface, and optionally featuring a perimeter frame or opaque film for enhanced aesthetics and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If opaque metal or plastic louver panels are used, then structural strength is improved, but aesthetic appearance and light transmission deteriorate
Solution Approach 1:
The patent changes the material parameter from opaque metal/plastic to transparent glass, transforming the louver panels from purely structural to both structural and aesthetic elements that allow light transmission while maintaining strength
Solution Approach 2:
The patent uses composite construction with glass panels joined by encapsulation portions, creating a hybrid structure that combines the strength of molded materials with the aesthetic and light-transmitting properties of glass
2Shape
If glass panels are joined by encapsulation portions, then aesthetic appearance and integration are improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the joining function and the aesthetic frame into a single encapsulation portion that both connects glass panels and provides the visible louver structure, eliminating separate components
Solution Approach 2:
The encapsulation portions serve multiple functions simultaneously: structural joining of glass panels, aesthetic framing, and defining the louver configuration, reducing overall device complexity
3Shape
If louvered configuration is implemented, then aesthetic appearance is improved, but structural stability deteriorates
Solution Approach 1:
The patent segments the window assembly into multiple glass panels arranged in a louvered configuration, with each panel independently supported by encapsulation portions, distributing structural loads
Solution Approach 2:
The encapsulation portions act as intermediary elements between adjacent glass panels, providing mechanical connection and structural support that maintains stability while allowing the louvered aesthetic configuration

AI summary
A window assembly for a vehicle includes a plurality of window panels arranged with at least one pair of adjacent window panels, with adjacent edge portions of adjacent ones of the window panels joined by a respective molded joining element. The adjacent edge portions joined by a respective molded joining element are offset or non-coplanar. The molded joining element may comprise an encapsulation that at least partially receives a perimeter edge portion of at least one of the adjacent window panels. The molded joining element may at least partially receive a rear perimeter edge portion of a forward window panel and may not overlap an outer surface of the forward window panel, with the molded joining element at least partially receiving a front perimeter edge portion of a rearward window panel.
