Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle window assemblies that emit light suffer from compromised sealing and optical performance due to holes for light sources, increasing technical costs and complexity.
Innovation Solution
A vehicle window assembly design that incorporates light guide strips within a sealing box, fixed to the window glass sheet without holes, using fixing members, and includes light-emitting modules and shielding members to achieve illumination and aesthetic effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If holes are defined in the bright strip to arrange light sources, then light emission effect is achieved, but sealing performance and optical performance are destroyed
Solution Approach 1:
A light guide strip is introduced as an intermediary component between the light source and the bright strip. The light guide strip receives light from the light source and guides it to the bright strip, eliminating the need for holes in the bright strip. This mediator enables light transmission while preserving the integrity and sealing performance of the bright strip structure.
Solution Approach 2:
The patent replaces the mechanical hole-punching method with an optical guidance system. Instead of creating physical openings in the bright strip, light is guided through the light guide strip to the bright strip surface, substituting a mechanical structural modification with an optical transmission mechanism that preserves the original structure.
2Illumination intensity
If holes are defined in the bright strip to arrange light sources, then light emission effect is achieved, but additional cooperation between hole and light source increases technical costs
Solution Approach 1:
The light guide strip and bright strip are merged into an integrated structure where the light guide strip is positioned behind the bright strip. This combination eliminates the need for separate hole definitions and light source arrangements, reducing the number of components and simplifying the overall structure while maintaining the light emission function.
Solution Approach 2:
The light guide strip serves multiple functions: it guides light from the light source, transmits light to the bright strip, and eliminates the need for holes in the bright strip. This multi-functional component reduces the overall system complexity and technical costs by consolidating several functions into a single element.

AI summary
A vehicle window assembly and a vehicle are provided in the disclosure. The vehicle window assembly includes multiple light guide strips spaced apart from each other, a vehicle window glass sheet, and a sealing box. The multiple light guide strips are arranged on one side surface of the vehicle window glass sheet, the sealing box is disposed at one side of each of the multiple light guide strips away from the vehicle window glass sheet, the sealing box defines grooves at positions respectively corresponding to the multiple light guide strips, and each of the multiple light guide strips is received in one of the grooves. The multiple light guide strips are received in the sealing box, the sealing box is directly fixed to the vehicle window glass sheet by the fixing member, thus there is no need to define a hole in the vehicle window glass sheet, thereby ensuring the sealing performance, optical performance, etc. of the vehicle window assembly and decreasing the technical costs.
