Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering column modules face limitations in transmitting the movement of the steering column lever safely and precisely, particularly due to the design of toothed elements that restrict mobility and require specific installation space, especially in areas with numerous components.
Innovation Solution
A steering column module with a toothed coupling device featuring a first toothed element in the base module and a second arcuate toothed element connected to the steering column arm, allowing for improved coupling and reduced installation space constraints, along with a magnetic evaluation unit for precise detection of the lever's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the toothed elements are arranged in the conventional manner (front-facing orientation along the longitudinal axis), then the coupling between steering column lever and base module is secure, but the installation space required is excessive and the mobility of the steering column lever is restricted
Solution Approach 1:
The second toothing element is oriented in a wing-like manner projecting from the side wall, extending laterally adjacent to the longitudinal axis rather than along it. This dimensional reorientation reduces the space required along the longitudinal axis while maintaining coupling effectiveness through the lateral extension of the toothed rack.
2Stability of the object's composition
If the toothed elements are arranged in the conventional manner, then the coupling is stable, but the mobility of the steering column lever in multiple spatial directions is restricted
Solution Approach 1:
By extending the second toothing element laterally from the side wall in a wing-like configuration, the design enables the steering column lever to move more freely along the longitudinal axis while maintaining stable coupling through the lateral toothed engagement. This dimensional change decouples the stability function from the mobility constraint.
3Adaptability or versatility
If numerous components are arranged in the limited installation area, then the steering column module integrates multiple functions, but the available space for coupling mechanisms is reduced
Solution Approach 1:
The wing-like lateral orientation of the second toothing element utilizes the lateral space adjacent to the longitudinal axis, effectively using previously underutilized spatial dimensions. This allows multiple components to be integrated along the longitudinal axis without compromising the coupling mechanism's space requirements.
Solution Approach 2:
The coupling mechanism is segmented into two distinct toothing elements with different orientations: the first toothing element in the base module and the second toothing element on the side wall of the coupling section. This segmentation allows each element to be optimized for its specific spatial orientation and function.
