Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing transverse leaf spring assemblies require modifications to accommodate different cross-sectional geometries, leading to cumbersome installations and increased complexity due to varying stiffness requirements for vehicle weight, comfort, and dynamics, despite sharing the same installation space in a vehicle line.
Innovation Solution
A transverse leaf spring assembly with an adapter system that includes a holder and elastic dampers, allowing for the integration of transverse leaf springs with diverse cross-sectional geometries within a fixed installation space, using adapters that match the specific geometry of each spring, eliminating the need for modifications to the bearing unit or attachment points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different transverse leaf springs with diverse cross sectional geometries are used to meet different stiffness requirements, then vehicle performance (comfort, dynamics, weight) is improved, but the complexity of installation and assembly increases due to required modifications for each spring type
Solution Approach 1:
The bearing unit holder is designed with a universal adaptation capability through the use of adapters. The holder can accommodate multiple types of transverse leaf springs with different cross-sectional geometries by selecting appropriate adapters, making a single holder design suitable for various spring types without requiring modifications to the holder itself.
Solution Approach 2:
An adapter is introduced as an intermediary component between the bearing unit holder and the transverse leaf spring. The adapter matches the specific cross-sectional geometry of different leaf springs while maintaining a standardized interface with the holder, thereby simplifying installation by decoupling the holder design from spring-specific geometry requirements.
2Adaptability or versatility
If modifications are made to the bearing unit or attachment points to accommodate different transverse leaf spring geometries, then compatibility with various spring types is improved, but the time and effort required for assembly increases
Solution Approach 1:
Adapters are pre-configured with specific cross-sectional geometries that match different transverse leaf spring types. This preliminary preparation allows for quick selection and installation without requiring on-site modifications to the bearing unit or attachment points, significantly reducing assembly time.
Solution Approach 2:
The bearing unit holder maintains a standardized universal design that works with all adapter types. This universality eliminates the need to modify the holder for each spring type, allowing rapid assembly by simply changing the adapter component rather than reconfiguring the entire bearing unit.
3Ease of manufacture
If a fixed installation space is used for transverse leaf springs in a vehicle line, then manufacturing consistency and assembly standardization are improved, but the ability to accommodate different cross sectional geometries deteriorates
Solution Approach 1:
The bearing unit is segmented into distinct functional components: a standardized holder that defines the installation space and spring-specific adapters that accommodate different cross-sectional geometries. This segmentation allows the holder to maintain fixed manufacturing specifications while adapters provide geometric adaptability.
Solution Approach 2:
The adapter serves as an intermediary that bridges the fixed installation space of the holder and the variable cross-sectional geometries of different leaf springs. It maintains manufacturing consistency at the holder level while enabling geometric diversity through the adapter-spring interface.

AI summary
A transverse leaf spring assembly for a motor vehicle includes a transverse leaf spring which is arranged transversely to the motor vehicle. A bearing unit connects the transverse leaf spring to a body of the motor vehicle and has a holder and elastic dampers. Accommodated in the holder is an adapter which has an interior space suited to a cross sectional geometry of the transverse leaf spring, with the transverse leaf spring being received in the adapter between the elastic dampers.
