Straddle Vehicle Step Bracket Structure for Vibration Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing straddle type vehicles experience significant vibration in the step where the occupant places their foot, affecting the riding comfort.
Innovation Solution
A step device with a holder that includes a bracket that includes a protruding portion to support the step, reducing vibration by stabilizing the step through a combination of a bracket and a stay with a protruding portion that abuts the step, enhancing the contact area and reducing vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple bracket structure is used to support the step, then the device complexity is reduced, but the vibration of the step increases
Solution Approach 1:
The bracket is divided into multiple functional portions: a base portion for mounting, two support portions extending to sandwich the step, and a protruding portion that abuts the step. This segmentation allows each portion to perform its specific function optimally while maintaining overall structural simplicity.
Solution Approach 2:
The protruding portion acts as an intermediary element between the bracket and the step, providing direct contact and support. This intermediary structure effectively transmits and distributes forces, reducing step vibration without requiring a complex overall bracket design.
2Stability of the object's composition
If the bracket firmly supports the step to reduce vibration, then the step stability is improved, but the rotational adjustability is reduced
Solution Approach 1:
Different portions of the bracket have different functional qualities: the support portions provide rotational freedom and adaptability, while the protruding portion provides firm local contact for stability. This local differentiation allows the bracket to simultaneously achieve both rotation capability and vibration reduction.
Solution Approach 2:
The bracket design allows the step to rotate dynamically around the support portions while the protruding portion maintains stable contact. This dynamic capability enables the step to adjust to different positions and orientations while still being firmly supported to reduce vibration.
