Window Assembly Sealing Profile and Guiding Bracket Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current window assemblies for motor vehicles face challenges in achieving a smooth transition between the window pane and the vehicle's door frame members, particularly in terms of sealing and guiding, which affects the vehicle's environmental and design considerations.
Innovation Solution
A window assembly comprising a door frame member, a movable window pane with a guiding section, and a window sealing profile with a mounting portion that forms a form-fitting engagement with the door frame member, along with a guiding bracket that applies an inward force to press the window pane against the sealing profile, ensuring a flush surface and effective sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a window assembly uses a separate sealing profile and guiding mechanism, then the sealing and guiding functions are achieved, but the transition between the window pane and door frame member is not smooth, creating visible gaps or steps
Solution Approach 1:
The patent combines the sealing profile and guiding bracket into a single integrated component. The guiding bracket includes both the sealing portion that contacts the window pane and the guiding portion that directs movement, eliminating the need for separate sealing and guiding components. This merging achieves a smooth transition surface while maintaining functional complexity through integration.
Solution Approach 2:
The guiding bracket is designed as a multi-functional component that simultaneously performs sealing, guiding, and positioning functions. The sealing portion provides moisture and acoustic sealing, while the guiding portion directs window pane movement, and the overall structure maintains the flush surface transition. This universal design reduces the number of separate components needed.
2Reliability
If the window pane is pressed against the sealing profile to ensure effective sealing, then sealing performance improves, but the guiding mechanism becomes more complex
Solution Approach 1:
The sealing function and guiding function are merged into a single guiding bracket component. The sealing portion integrates with the guiding portion, so the same structure that provides sealing also provides guiding. This eliminates the need for a separate complex guiding mechanism while maintaining reliable sealing performance.
Solution Approach 2:
The guiding bracket is designed to automatically apply the necessary pressing force to the window pane through its own structural configuration during installation and operation. The bracket's geometry and mounting arrangement create the inward force needed for sealing without requiring additional actuators or complex adjustment mechanisms.
3Shape
If the guiding bracket applies inward force to press the window pane against the sealing profile, then sealing and flush surface are achieved, but the bracket structure becomes more complex
Solution Approach 1:
The force application mechanism is integrated into the guiding bracket's basic structure rather than being a separate component. The bracket's mounting portion and body are designed to naturally generate the inward pressing force through their geometric arrangement and connection to the door frame member, achieving the flush surface without adding structural complexity.
Solution Approach 2:
The guiding bracket is pre-configured during manufacturing with the necessary geometric features and mounting arrangements to automatically apply the required inward force when installed. This preliminary design ensures that the flush surface is achieved upon installation without requiring additional adjustment mechanisms or complex structural features during operation.

A window assembly (170) for a window opening of a motor vehicle comprises a door frame member (22), a movable window pane (130), a window sealing profile (100), and a guiding bracket (150). The movable window pane (130) includes a guiding section (136) and a window section (131) having an outer window surface (132). The window sealing profile (100) is fastened to the door frame member (22) and includes a sealing portion (110, 111, 112, 120) for sealing the window pane (130) against moisture and/or noise. The guiding bracket (150) includes a trimming surface (155) and is configured to guide the window pane (130) along a direction of movement between an open position and a closed position, and vice versa. The guiding bracket (150) simultaneously engages the window sealing profile (100) and the window pane (130), when in the fastened state.
