Adjustable Glass Track Sealing for Frameless Vehicle Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sealing relative to movable or removable components in vehicle door assemblies and roof structures is challenging, particularly in establishing continuous seal planes around glass panels.
Innovation Solution
An adjustable glass track system comprising a tubular frame rail, channel rail, appliques, and seals that work together to create continuous seal planes around the periphery of glass panes and roof structures, using a combination of flanges, locator pins, and fasteners to ensure effective sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sealing methods are used for movable glass panels, then the structure is simple, but continuous seal planes cannot be established
Solution Approach 1:
The sealing system is divided into multiple segments: a first seal on the channel rail for the top edge of the glass pane, and a second seal on the applique for the side edge of the glass pane. These segmented seals work together to form a continuous seal plane, resolving the contradiction by breaking down the complex sealing requirement into manageable segments that can be independently positioned and adjusted.
Solution Approach 2:
The applique acts as an intermediary component between the channel rail and the glass pane. It provides a mounting surface for the second seal and connects to the channel rail through定位 features, enabling the formation of a continuous seal plane without requiring direct connection between the seal and the moving glass pane, thus maintaining reliability while managing complexity.
2Adaptability or versatility
If fixed sealing structures are used, then manufacturing is simple, but adaptability to movable components is poor
Solution Approach 1:
The channel rail and applique are designed with adjustable positioning capabilities. The channel rail can be positioned at different locations along the tubular frame rail, and the applique can be adjusted relative to the channel rail. This dynamic adjustability allows the sealing system to adapt to the movable glass pane while maintaining manufacturing feasibility through standardized components and assembly procedures.
Solution Approach 2:
The channel rail serves multiple functions: it provides structural support, mounts the first seal for sealing, and positions the applique. The applique similarly provides structural support, mounts the second seal, and connects to the channel rail. This multi-functionality increases adaptability to different configurations while avoiding the need for separate specialized components, thereby maintaining ease of manufacture.
3Reliability
If multiple sealing components are used to establish continuous seal planes, then sealing performance is improved, but device complexity increases
Solution Approach 1:
The channel rail and applique are merged into an integrated assembly where the applique is mounted to the channel rail. This merging reduces the number of separate components compared to having entirely separate sealing structures. The integrated assembly works together with the tubular frame rail to establish the continuous seal plane, improving sealing performance while limiting the increase in device complexity through functional integration.
