Vehicle Window Regulator Layout With Separated Pulley and Guide Rail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing window regulator assemblies in vehicles have complex and costly guide rails due to their deep-drawn design, which increases manufacturing complexity and costs.
Innovation Solution
The pulley arrangements and guide rails are mounted as separate parts on the carrier element without direct contact, with connection sections and centring elements ensuring precise alignment, allowing for a simpler and cheaper design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the guide rail is designed as a deep-drawn receiving device for pulley arrangements, then the guide rail can support the pulley arrangements and withstand glass closing and opening forces, but the manufacturing complexity and costs increase
Solution Approach 1:
The system is divided into separate functional components: the guide rail (providing linear guidance) and the pulley arrangement (mounted separately on the carrier element). This segmentation allows each component to be optimized independently - the guide rail can be a simpler, cheaper profile element without deep-drawn receiving sections, while the pulley arrangement is mounted separately on the carrier element, eliminating the need for complex integrated guide rail designs.
2Strength
If the guide rail has integrated receiving sections for pulley arrangements, then the guide rail can provide structural support, but the guide rail design becomes complex and expensive
Solution Approach 1:
The guide rail is separated from the pulley arrangement mounting function. The guide rail becomes a simple profile element providing linear guidance, while the pulley arrangement is mounted separately on the carrier element. This eliminates the need for integrated receiving sections in the guide rail, significantly reducing design complexity.
Solution Approach 2:
The mounting function for pulley arrangements is merged with the carrier element rather than the guide rail. The carrier element provides both structural support and mounting surfaces for pulley arrangements, while the guide rail focuses solely on providing linear guidance paths for sliders.
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 material requirements and manufacturing costs by eliminating the need for robust guide rail interfaces, enabling a lighter and more economical assembly.
Implementation Method 1
the connection sections comprise flanges for resting on the surface of the carrier element
Implementation Method 2
For a precise alignment of the guide rail relative to the carrier element centring elements (guide rail locators) can be arranged at the connection sections or at the carrier element
Implementation Method 3
at least one pulley arrangement for redirecting a cable is mounted at the carrier element
