Vehicle Window Seal Plastic Strand With Pin Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seal arrangements for vertically movable vehicle window panes face challenges in precise fitting and alignment due to lack of effective stop mechanisms, leading to potential misplacement and increased complexity in manufacturing and customization for different vehicle types.
Innovation Solution
A plastic strand component with stop means, such as pin elements, is used to facilitate precise placement and connection with other seal components, allowing for accurate positioning and adaptation to various vehicle geometries, while maintaining simplicity and standardization of other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If stop means are added to the plastic strand component, then positioning precision and assembly efficiency are improved, but device complexity increases
Solution Approach 1:
The seal arrangement is divided into multiple independent strand components (plastic strand component, elastomer seal components) that can be manufactured separately and then assembled together using stop means and plug-in connections, improving positioning precision while keeping individual components simple
Solution Approach 2:
Stop means are pre-integrated into the plastic strand component during manufacturing, enabling precise positioning to be established before final assembly occurs, thus improving positioning precision without adding complexity during the assembly process
2Reliability
If multiple seal strand components are connected to the plastic strand component, then sealing performance is improved, but device complexity increases
Solution Approach 1:
Multiple seal strand components (first seal component, second seal component) are merged with the plastic strand component through plug-in connections and stop means, creating a unified multi-functional assembly that provides both sealing and positioning functions while maintaining manageable complexity
Solution Approach 2:
The plastic strand component serves multiple functions: it provides structural support, positioning (via stop means), and serves as a carrier for multiple seal components, thereby improving sealing performance without proportionally increasing overall device complexity
3Adaptability or versatility
If the seal arrangement is customized for different vehicle types, then adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
The seal arrangement is segmented into modular components that can be selectively combined or configured for different vehicle types, allowing customization while maintaining standardized manufacturing processes for each individual component
Solution Approach 2:
The plastic strand component with integrated stop means serves as a universal carrier that can accommodate different seal configurations for various vehicle types (A pillar, B pillar, C pillar applications), enabling adaptability without increasing the complexity of the core component design

AI summary
A sealing arrangement for guiding and sealing a vertically movable vehicle window pane, having a plurality of strand components, which can be interlockingly and/or frictionally connected to each other and to the vehicle body, wherein the strand components include a strand component made of plastic, which extends along an upper edge of the vehicle window pane when the vehicle window is closed. The strand component made of plastic has a stopping element for locking the plastic strand component in the longitudinal direction of the strand during assembly of the sealing arrangement on the vehicle body. The stopping element preferably includes at least one journal element, protruding from a longitudinal side of the plastic strand component, for engaging in an opening in the vehicle body.
