Quarter Window Assembly With Integrated Sealing and Easier Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing quarter window assembly in automobiles is cumbersome to install, has poor sealing performance due to the lack of a sealing structure between the quarter window glass and the guide rail, and results in low manufacturing efficiency.
Innovation Solution
A quarter window assembly featuring a triangular glass with a guide rail, a sealing member, and a fixing assembly including a lifting member and a fixing bracket, where the lifting member is bonded or snapped to the glass and the fixing bracket is welded or riveted to the guide rail, allowing for a frameless design with improved sealing and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the existing quarter window assembly structure with multiple components (internal guide rail, guide groove, external guide rail, rubber quarter windows, quarter window glass) is used, then the quarter window can be assembled, but the installation process becomes cumbersome and manufacturing efficiency is low
Solution Approach 1:
The patent combines multiple separate components (guide rail, sealing member, fixing assembly) into an integrated quarter window assembly structure. The guide rail and sealing member are pre-assembled as one unit, and the fixing assembly is integrated with the guide rail, reducing the number of separate installation steps and improving manufacturing efficiency
Solution Approach 2:
The quarter window assembly is divided into distinct functional modules: the guide rail component, the sealing member, and the fixing assembly. This segmentation allows for standardized production of each module and simplifies the overall assembly process by allowing pre-fabricated modules to be installed as units
2Reliability
If the existing quarter window assembly without sealing structure between quarter window glass and guide rail is used, then the structure is simpler, but the sealing performance is poor
Solution Approach 1:
A sealing member is introduced as an intermediary component between the quarter window glass and the guide rail. This sealing member (which may be rubber or plastic material) fills the gap and provides effective sealing, preventing water and air infiltration while maintaining a relatively simple overall structure
Solution Approach 2:
The sealing member is made of flexible rubber or plastic material that can deform to accommodate manufacturing tolerances and installation variations. This flexible sealing element effectively seals the gap between the rigid guide rail and quarter window glass without requiring complex sealing mechanisms
3Ease of operation
If the existing quarter window assembly with multiple installation steps is used, then all components can be connected, but the installation time and labor are increased
Solution Approach 1:
The guide rail and sealing member are pre-assembled into an integrated unit before installation. The fixing assembly is also pre-attached to the guide rail. This preliminary assembly reduces the number of steps during actual installation, as the pre-assembled unit can be installed as one component rather than assembling multiple parts on-site

AI summary
The subject disclosure discloses a quarter window assembly and an automobile with the same. The quarter window assembly comprises a triangular glass, a guide rail, a sealing member and a fixing assembly; the guide rail is provided with groove and a fixing portion disposed close to the groove; the sealing member is snapped into the groove, and a side edge of the triangular glass is fixed on the fixing portion and abuts against the sealing member. The fixing assembly includes a lifting member and a fixing bracket, the lifting member is disposed on a bottom edge of the triangular glass and is suitable for being fixed on the door sheet metal, and the fixing bracket is disposed on the guide rail and is suitable for being fixed on the door sheet metal.
