Molding Element Closure Element Protects Latching Recess
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing molding elements for joining parts to vehicle window panes face challenges such as deformation, dirt accumulation, and the need for separate keder rails, which increase logistical and production costs, and complicate the installation process.
Innovation Solution
A molding element with a closure element that protects the latching recess from dirt and deformation, allowing for reliable and easy adaptation to the window pane contour without separate keder rails, by integrating a closure element that supports and secures the latching recess during transportation and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate keder rail is inserted into the latching groove to protect it during transportation and installation, then the latching groove is protected from deformation and dirt, but the device complexity and logistical costs increase due to the need for additional components
Solution Approach 1:
The closure element is integrated directly into the molding element as a unified component. The closure element forms an integral part of the molding body, eliminating the need for separate keder rails while maintaining the protective function for the latching groove during transportation and installation
Solution Approach 2:
The molding element serves multiple functions: it provides the structural support for the window pane, contains the latching groove for securing parts, and includes the closure element for protection. This multi-functional design eliminates the need for dedicated protective components
2Adaptability or versatility
If the molding element is bent to adapt to the window pane contour, then it can be properly installed on the window edge, but the latching groove may become deformed making joining difficult or impossible
Solution Approach 1:
The closure element is positioned in advance to bridge the engagement opening before any bending or installation operations occur. This preliminary positioning ensures the latching groove maintains its precise geometry even when the molding element is subsequently bent to match the window contour
Solution Approach 2:
The closure element acts as a protective structure that cushions and supports the latching groove area during handling and installation. This beforehand protection prevents deformation of the precision-critical latching groove while allowing the rest of the molding element to be adapted to the window contour
3Ease of operation
If the latching groove is exposed during transportation and storage, then access is easy, but dirt particles accumulate in the groove hindering the latching of the water trough cover
Solution Approach 1:
The closure element is designed to be movable, allowing it to be opened when access to the latching groove is needed and closed when protection is required. This dynamic design provides both protection during transportation and ease of access during installation and maintenance
Solution Approach 2:
The closure element can be temporarily removed or opened to allow access to the latching groove for installation operations, then replaced to provide ongoing protection. This extraction approach allows selective exposure only when necessary

AI summary
A molding element for joining a part to a vehicle window pane includes a molding body having a first section configured to be secured to an edge of the window pane and a second section including a latching recess being configured to receive, in an insertion direction, a rib of the part through an engagement opening so as to detachably fasten the part to the molding element. A closure element is formed on the molding body. The closure element bridges the engagement opening in a first functional position.
