Vehicle Window Regulator Pane Adapter Alignment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window regulator arrangements for motor vehicles are costly due to numerous components, difficult to assemble precisely, and lack quick-release systems, leading to inefficiencies in aligning the window pane with the adjustment mechanism and tolerance compensation.
Innovation Solution
A window lifter arrangement featuring a pane adapter with a U-shaped holding section and a guide carriage with a seat formed by a guide leg and a fastening leg, where the guide leg engages with an insertion channel to ensure precise alignment, and a fastening mechanism for secure attachment, allowing for easy and cost-effective assembly and tolerance adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a threaded screw and run-in slope are used to align the connecting part with the driver, then precise alignment is achieved, but the number of components increases and manufacturing cost rises
Solution Approach 1:
The patent combines the alignment function and fastening function into a single component - the guide carriage with guide surfaces that directly guide the connecting part into correct alignment while serving as the mounting structure, eliminating the need for separate run-in slope and threaded screw components
Solution Approach 2:
The guide carriage serves multiple functions simultaneously: it provides the run-in slope for alignment, acts as the mounting structure with threaded hole for fastening, and guides the connecting part into correct position, making one component perform multiple roles that previously required separate parts
2Reliability
If a clamping element with ribs and webs is used to clamp the window pane, then the window pane is securely held, but lateral offset during insertion becomes difficult to avoid and assembly time increases
Solution Approach 1:
The guide carriage is pre-positioned on the driver with its guide surfaces oriented correctly, so that when the connecting part is inserted, the alignment action has already been prepared, allowing the connecting part to be guided into correct alignment automatically during the insertion process without requiring subsequent adjustment
3Ease of operation
If a flat groove is provided in the clamping section, then the guide carriage can engage with the pane adapter, but the rigidity of the pane adapter is reduced due to decreased wall thickness
Solution Approach 1:
The elevation is provided only in the specific region where the guide leg needs to engage, rather than creating a complete flat groove around the clamping section, thus maintaining the rigidity of the pane adapter in areas where structural strength is needed while still providing the necessary engagement surface for the guide leg
4Reliability
If both the pane adapter and guide carriage must be attached to the hole in the window pane, then connection is achieved, but tolerance compensation is not possible
Solution Approach 1:
The guide carriage acts as an intermediary component between the driver and the pane adapter, providing guide surfaces that mediate the alignment process and allow tolerance compensation for variations in hole position, while still ensuring stable connection of both components to the window pane

AI summary
The invention relates to a window lift arrangement for a motor vehicle, comprising an adjustable window glass, an adjusting device having a drive and a carrier arrangement, comprising a glass adapter and a guide carrier, wherein the glass adapter comprises a substantially U-shaped mounting segment for affixing the window glass and a flat clamping segment and is disposed at an edge area of the window glass, and wherein the guide carrier is disposed on the adjusting device and comprises a seat that is engaged with the clamping segment of the glass adapter, wherein the clamp segment comprises an insertion channel formed by at least one raised area, by which an intended alignment of the glass adapter to the guide carrier is achieved when inserting the clamping segment of the glass adapter into the seat of the guide carrier.
