Steering Column Switch Module Mount for Stable Accessory Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering column designs with switch modules lack a simple and space-saving method for creating a stable mounting for objects, requiring structural modifications and not easily adaptable when a mounting is not needed.
Innovation Solution
A mechanical interface is designed as a separate component attached to the switch module, providing a contour for attaching a mounting that can be easily plugged in and secured, with an H-shaped configuration for secure retention and the option to cover the interface when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical interface for mounting objects is integrated into the switch module, then the mounting stability is improved, but the structural complexity and modification requirements increase
Solution Approach 1:
The mechanical interface is separated from the switch module and implemented as an independent component that can be attached to the steering column. This segmentation allows the mounting function to be added without modifying the switch module structure, thus improving mounting stability while avoiding increased device complexity.
Solution Approach 2:
An intermediate mechanical interface component serves as a mediator between the steering column and the mounting. This intermediary element provides the mounting functionality without requiring direct integration into the switch module, thereby maintaining structural simplicity while ensuring reliable mounting.
2Reliability
If a mechanical interface is integrated into the switch module, then the mounting reliability is improved, but the space requirement and design flexibility are reduced
Solution Approach 1:
By segmenting the mechanical interface as a separate attachable component rather than integrating it into the switch module, the design maintains flexibility. The interface can be attached or removed independently, allowing the system to adapt to different mounting requirements without compromising mounting reliability.
Solution Approach 2:
The mechanical interface is designed as a dynamic, optionally attachable component rather than a fixed integrated structure. This allows the system to adapt its configuration based on whether mounting functionality is required, improving design versatility while maintaining reliable mounting when needed.
3Stability of the object's composition
If the switch module encloses the steering column in a form-locked manner, then the rotational movement transfer is improved, but the accessibility for mounting objects is reduced
Solution Approach 1:
The mechanical interface acts as an intermediary element that provides mounting accessibility without interfering with the form-locked enclosure of the steering column. This intermediary component enables easy mounting operations while the switch module maintains its stable rotational movement transfer function.
Solution Approach 2:
The form-locked enclosure is maintained in the regions required for rotational movement transfer, while the mechanical interface provides localized accessibility for mounting objects. This local differentiation allows both functions to coexist without compromising either rotational stability or mounting ease.
