Vehicle Window Sealing Structure for Sunroof Glass Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The replacement of either of two adjacent vehicle windows in a panoramic sunroof system often disrupts the sealing structure, requiring cumbersome and costly reassembly of all windows to restore the sealing function, due to the sagging of the sealing lip on the windshield when the sunroof glass is dismounted.
Innovation Solution
A sealing structure with a first and second sealing member, each having a sealing lip, allows for partial connection in either direction to maintain sealing integrity during replacement, featuring deformation portions and grooves to ensure stable overlap and sealing even after reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the sunroof glass is disassembled for replacement, then the sealing lip sags due to lack of support, but this causes the sealing function to fail and requires cumbersome reassembly of all windows
Solution Approach 1:
The sealing lip is preliminarily supported by the sealing groove on the adjacent glass before the sunroof glass is disassembled. This preliminary support structure prevents the sealing lip from sagging when the sunroof glass is removed, maintaining the sealing function without requiring reassembly of all windows. The support relationship is established in advance to prevent the harmful effect of sagging.
Solution Approach 2:
The sealing groove on the adjacent glass acts as an intermediary support structure for the sealing lip. This intermediary element provides the necessary support when the sunroof glass is removed, preventing the sealing lip from sagging and maintaining the sealing function without requiring complete disassembly and reassembly of all windows.
2Reliability
If the sealing lip is supported by the adjacent glass, then the sealing function is maintained during replacement, but the structure becomes more complex
Solution Approach 1:
The sealing support function is merged with the adjacent glass by forming a sealing groove directly on its surface. This eliminates the need for separate support structures or components, as the adjacent glass itself provides both the sealing surface and the support function. The structure achieves enhanced reliability without increasing device complexity through this functional merging.
Solution Approach 2:
The adjacent glass performs multiple functions: it serves as both the sealing surface for the joint and the support structure for the sealing lip during replacement. This multi-functionality eliminates the need for dedicated support components, maintaining structural simplicity while ensuring the sealing function is preserved during sunroof glass replacement.
3Reliability
If all windows are disassembled and reassembled to restore sealing function, then the sealing performance is restored, but the replacement process becomes time-consuming and costly
Solution Approach 1:
The sealing groove is preliminarily formed on the adjacent glass to provide support for the sealing lip before any disassembly occurs. This preliminary preparation ensures that when the sunroof glass is replaced, the sealing lip maintains its position and sealing function without requiring the time-consuming process of disassembling and reassembling all windows. The protective support structure is in place in advance to prevent the need for extensive rework.

AI summary
A sealing structure configured to seal a junction between a first component (1) and a second component (2), in which the sealing structure includes: a first sealing member (3), which is configured to be in sealed connection with the first component (1) and provided with a first sealing lip (301); and a second sealing member (4), which is configured to be in sealed connection with the second component (2) and provided with a second sealing lip (401); at least a portion of the first sealing lip (301) is in sealed connection with at least a portion of the second sealing lip (401). The present disclosure solves the technical problem that the replacement of either of two adjacent glasses leads to the failure of a sealing structure therebetween. Further, a vehicle window provided with the sealing structure and a vehicle provided with the vehicle window are disclosed.
