Vehicle Window Frame With Integrated Clip Assembly for Trim Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window unit fastening methods result in shrinkage cavities and complex assembly processes, particularly when using clip-type fastenings for trim elements, which are unsatisfactory from an economic and handling standpoint.
Innovation Solution
A window unit design featuring a frame with a primary part that includes a single, integrated clip-like assembly comprising a top and bottom element, allowing easy clipping and maintenance of a trim element, with the top element shifted along the edge to stabilize the trim, and both elements being flexible perpendicular to the trim's penetration axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If clip-type fastening methods are used to attach trim elements, then ease of installation and replacement is improved, but shrinkage cavities are formed in the seal region and assembly complexity increases
Solution Approach 1:
The patent merges the seal and the clip-like assembly into a single integrated component. The seal is molded with integrated clip-like assemblies that include top and bottom elements for securing trim elements. This integration eliminates the need for separate fastening components, thereby preventing shrinkage cavities that would form with separate clip components while maintaining ease of installation through the clip mechanism.
2Ease of repair
If separate clip components are assembled onto the seal, then trim element replacement is facilitated, but manufacturing complexity and handling requirements increase
Solution Approach 1:
The seal is molded with integrated clip-like assemblies that include top and bottom elements for securing trim elements. This integration eliminates the need for separate fastening components, thereby simplifying the manufacturing process while maintaining ease of trim element replacement through the clip mechanism.
Solution Approach 2:
The clip-like assembly is segmented into a top element and a bottom element that can move relative to each other. The top element can be shifted along the edge to stabilize the clipping action, and both elements are designed to be flexible perpendicular to the trim penetration axis, allowing easy insertion and replacement of trim elements while maintaining a simple integrated structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces shrinkage cavities and simplifies the assembly process by integrating the clip-like assembly with the primary part, ensuring robust and dimensionally stable window units with easy trim element replacement.
Implementation Method 1
the top element and the bottom element being designed to be flexible in a direction substantially perpendicular to the axis of penetration of a trim element to be plugged into the at least one clip-like assembly

AI summary
A window unit with a glazing panel, a frame with a profile that encompasses the glazing panel's edge, and grips the glazing panel on at least two peripheral sides as a ring; the frame has a primary part in the form of a hard component. The frame's primary part has at least one clip-like assembly that has top and bottom elements; the clip-like assembly clips and maintains the trim element's lug between the top and bottom elements. The top element is shifted from the bottom element along the edge. The clip-like assembly and the primary part are a single component. The top and bottom elements are flexible in a perpendicular direction to the axis of penetration of a trim element plugged into the clip-like assembly.
