Window Guiding Profile With Locating Means For Vehicle Side Window
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current window assemblies for motor vehicles face challenges in providing a smooth transition between the window pane and the vehicle's door frame, leading to potential misalignment and increased risk of the window pane disengaging during operation, which affects sealing and noise reduction.
Innovation Solution
A window assembly featuring a window guiding profile with a sealing portion, an inner guiding leg, an outer guiding leg, and a locating means that form-fittingly engages the window pane, along with a mounting bracket for reinforcement, ensuring reliable guidance and minimizing the risk of disengagement by applying torque and maintaining a flush surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional window guiding profile is used, then the structure is simple, but the window pane may disengage during operation due to insufficient guidance and sealing
Solution Approach 1:
The guiding profile is divided into distinct functional segments: an inner guiding leg for precise positioning, an outer guiding leg for structural support, and a sealing portion for preventing disengagement. This segmentation allows each part to perform its specific function optimally while maintaining overall reliability.
Solution Approach 2:
The window pane is nested within the guiding profile structure, with the guiding means positioned within the accommodating opening formed by the guiding legs. The sealing portion envelops the window pane edge, creating a nested configuration that prevents disengagement while maintaining a compact design.
2Manufacturing precision
If the window pane is guided with tight tolerances, then alignment and sealing are improved, but manufacturing difficulty increases
Solution Approach 1:
The guiding profile features localized guiding surfaces and sealing portions at critical areas where precision is needed, rather than requiring uniform high precision throughout the entire structure. The inner guiding leg provides localized positional guidance, while the outer guiding leg provides structural support with less stringent tolerance requirements.
Solution Approach 2:
The guiding means acts as an intermediary element between the window pane and the guiding profile, providing form-fitting engagement that accommodates normal manufacturing tolerances. This intermediary mechanism translates slight variations in manufacturing into acceptable positioning without requiring extremely tight tolerances across all components.
3Reliability
If the guiding profile is made more complex to prevent disengagement, then reliability improves, but the device complexity increases
Solution Approach 1:
The guiding function and sealing function are merged into a single integrated guiding profile structure. The inner guiding leg, outer guiding leg, and sealing portion are combined to simultaneously provide positioning, support, and prevention of disengagement, eliminating the need for separate components for each function.
Solution Approach 2:
The guiding profile is designed as a multi-functional component that simultaneously guides the window pane motion, seals the gap between the pane and door frame, and prevents disengagement during operation. This universal design reduces the overall number of components while improving reliability.

AI summary
A window assembly (150) of a side window opening of a motor vehicle comprises a door frame member (22) having an outer surface (26), a movable window pane (130) having an outer window surface (132) and a guiding member (140), and a window guiding profile (100). The window guiding profile (100) is fastened to the door frame member (22) and guides the window pane (130) along a direction of movement between an open position and a closed position. The window guiding profile (100) includes a sealing portion (105) for sealing the window pane (130), an accommodating opening (104), and a guiding leg (101). The guiding leg (101) comprises a locating member (110) which cooperates with the guiding member (140) to prevent a movement of the window pane (130) out of the accommodating opening (104).
