Reinforcement Paths in Multipart Carrier Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing path-controlled window adjustment devices for motor vehicles face challenges in ensuring sufficient strength and rigidity of the carrier assembly, particularly when dealing with large forces and complex movements required for various door designs.
Innovation Solution
The introduction of reinforcement paths formed by longitudinally extending formations or profilings on the carrier elements, which connect fixing points and provide additional structural support, along with the use of stronger materials like metal or fiber-reinforced plastics for the guide plate, enhance the rigidity and strength of the carrier assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the carrier assembly is designed as a multipart structure with multiple carrier elements connected at fixing points, then the adaptability to different door designs is improved, but the strength and rigidity of the carrier assembly deteriorates
Solution Approach 1:
The carrier assembly is divided into multiple carrier elements that can be selectively adapted to different door designs, while reinforcement paths connect the fixing points to maintain overall strength
Solution Approach 2:
Reinforcement paths are added as a new structural dimension connecting the fixing points on carrier elements, providing additional load-bearing capacity without interfering with the multipart adaptive design
2Adaptability or versatility
If the carrier assembly is designed as a multipart structure with multiple carrier elements connected at fixing points, then the adaptability to different door designs is improved, but the rigidity of the carrier assembly deteriorates
Solution Approach 1:
The carrier assembly is segmented into multiple adaptable carrier elements, with reinforcement paths providing the necessary rigidity by connecting fixing points
Solution Approach 2:
Reinforcement paths create an additional structural dimension that enhances rigidity by forming load-distributing connections between fixing points on different carrier elements
3Strength
If reinforcement paths are added to connect fixing points on carrier elements, then the strength of the carrier assembly is improved, but the device complexity increases
Solution Approach 1:
The reinforcement paths are merged with the carrier elements themselves, forming an integrated structure that strengthens the assembly without adding separate components
Solution Approach 2:
The reinforcement paths can be formed from different materials or structural configurations (such as ribs, beads, or profilings) that provide enhanced strength while maintaining design flexibility

AI summary
The invention relates to a path-controlled adjustment device for a window pane of a motor vehicle, with a carrier assembly, with at least two guideways provided at the carrier assembly, which define an adjustment path for an adjustable window pane and which are spaced from each other transversely to the adjustment path, and with a driver which on the one hand includes means for connection of the window pane to be adjusted and which on the other hand is in engagement with the guideways so as to be longitudinally movable. The carrier assembly consists of at least two carrier elements which are connected with each other at a plurality of fixing points. On at least one carrier element fixing points, via which that carrier element is to be fixed at a further carrier element of the carrier assembly, are connected with each other by reinforcement paths.
