Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for functionalized windowpanes in motor vehicles face challenges in signal transmission and cable management, leading to increased structural complexity, noise emissions, and construction space requirements, particularly in movable or adjustable windows.
Innovation Solution
An adjustment device with a carrier plate featuring a guide rail and a flexible, elastic component for guiding cables, which is connected to the windowpane, allowing for efficient signal transmission and control while minimizing noise and space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cable management systems are used for functionalized windowpanes, then signal transmission can be established, but structural complexity and construction space requirements increase
Solution Approach 1:
The patent combines the cable guide function with the existing guide rail structure. The cable guide is integrated into the guide rail assembly, eliminating the need for separate cable management components. This merging reduces structural complexity while maintaining reliable signal transmission to the functionalized windowpane.
Solution Approach 2:
The guide rail structure serves multiple functions: it guides the driver's movement and simultaneously guides the cable. This multi-functionality reduces the number of separate components needed, thereby reducing structural complexity while ensuring proper cable routing for signal transmission.
2Reliability
If conventional cable management systems are used for functionalized windowpanes, then signal transmission can be established, but construction space requirements increase
Solution Approach 1:
By merging the cable guide function into the existing guide rail structure, the patent eliminates the need for additional space-consuming cable management components. The cable is routed through the guide rail assembly itself, reducing the overall construction space required while maintaining reliable signal transmission.
3Reliability
If conventional cable management systems are used for functionalized windowpanes, then signal transmission can be established, but noise emissions increase
Solution Approach 1:
The integration of cable guidance into the guide rail structure eliminates loose cable sections that would otherwise flap and create noise during door closing operations. The cable remains properly routed and constrained throughout the window's movement range, reducing noise emissions while maintaining signal transmission reliability.
4Ease of manufacture
If lever or additional slotted guideway aids are used for cable conduction, then cable management is improved, but device complexity and construction space requirements increase
Solution Approach 1:
The patent merges the cable guidance function directly into the existing guide rail structure, eliminating the need for separate lever mechanisms or additional slotted guideway aids. This integration maintains proper cable management while reducing device complexity by removing redundant components.

AI summary
An assembly of an adjustment device of a motor vehicle includes a support plate, on which at least one guide rail is disposed. A driver is movably guided on the guide rail, for a functionalized windowpane, in particular an electrically switchable or controllable windowpane. A flexible component is provided for guiding a cable which is connected or can be connected to the functionalized windowpane, in particular for conducting a current and/or for controlling the functionalized windowpane. A window opener of a motor vehicle having the assembly is also provided.
