Straddled Vehicle Tandem Footrest Bracket Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing straddled vehicles face challenges in compactly integrating tandem footrests and brackets, leading to increased structure size and complexity, making attachment and removal cumbersome.
Innovation Solution
A straddled vehicle design featuring a common bracket for both tandem footrests, supported on a plate secured to the seat frames, allowing for easier attachment and removal by securing the bracket to the plate, which reduces the number of components and size, while maintaining a compact arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate brackets are provided for left and right tandem foot rests, then each foot rest can be independently attached, but the structure size increases and the number of components increases
Solution Approach 1:
The patent merges the left and right brackets into a single integrated bracket structure. The bracket includes a left bracket portion and a right bracket portion that are formed as one piece, allowing both tandem foot rests to be attached to the same bracket rather than requiring separate brackets. This reduces the number of components while maintaining the attachment functionality.
2Ease of operation
If left and right tandem foot rests are attached separately to left and right seat frames, then each can be positioned independently, but the attachment process becomes more troublesome and time-consuming
Solution Approach 1:
The patent combines the attachment operations for left and right tandem foot rests into a single operation. By providing a single bracket that supports both foot rests, the bracket can be attached to the seat frame once, and both foot rests are simultaneously secured. This reduces the attachment time and procedural complexity compared to attaching separate brackets independently.
Solution Approach 2:
The bracket is designed with segmented functional portions (left bracket portion and right bracket portion) that can be positioned independently to accommodate the left and right tandem foot rests at different locations. This segmentation within a unified structure allows independent positioning capability while maintaining a single attachment point.
3Device complexity
If tandem foot rest unit is integrated with rear fender, then structure size is reduced, but attachment and removal becomes more troublesome
Solution Approach 1:
The patent separates the bracket from the rear fender, making them independent components. The bracket is attached to the seat frame, while the rear fender remains a separate body component. This segmentation allows the bracket and tandem foot rests to be attached or removed independently without affecting the rear fender, maintaining ease of operation while achieving structure reduction through the unified bracket design.
