Load-Bearing Foot Support Assembly Without Separate Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle designs with straddle seats, such as motorcycles and ATVs, have separate brackets supporting foot controls, which are not integrated into the load-bearing frame structure, leading to inefficiencies and potential rigidity issues.
Innovation Solution
A foot support assembly where the foot support is directly connected to a structurally stressed frame member that acts as a load-bearing component, eliminating the need for intervening brackets and allowing for modular replacement and improved load distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If foot supports are supported by separate brackets bolted to the frame, then the frame structure and bracket are separate components, but this increases device complexity and reduces structural rigidity
Solution Approach 1:
The foot support is merged with the frame member by directly connecting the foot support to the load-bearing frame member, eliminating the separate bracket component. This integration reduces the number of parts while enhancing structural rigidity by making the foot support part of the frame's load-bearing structure.
2Productivity
If foot supports are supported by separate brackets, then installation is simplified, but this increases device complexity and reduces load-bearing efficiency
Solution Approach 1:
The foot support is integrated into the frame member, allowing it to directly bear loads through the frame's load-bearing structure. This merging eliminates the need for separate brackets and improves load-bearing efficiency by utilizing the frame's existing structural capacity.
3Strength
If foot supports are integrated directly into the frame member, then structural rigidity is enhanced, but this reduces ease of repair and replacement
Solution Approach 1:
The foot support assembly is segmented into a frame member portion and a foot support portion that can be independently removed. The frame member remains permanently integrated into the frame structure for rigidity, while the foot support portion can be detached and replaced without affecting the structural integrity of the frame.
4Ease of manufacture
If separate brackets are used for foot supports, then manufacturing is simplified, but this increases device complexity and reduces structural performance
Solution Approach 1:
The foot support and frame member are manufactured as an integrated assembly, eliminating the need for separate bracket components and their associated fastening hardware. This merging simplifies the overall manufacturing process by reducing the number of parts to produce, assemble, and quality-check.

AI summary
A foot support is directly supported by a structurally stressed but removable part of a vehicle frame. In particular, a foot support assembly includes a frame member and a foot support, such as a foot peg. The frame member forms a part of the load-bearing structure of the frame assembly, and the foot support is mounted to the frame member without any intervening brackets or components therebetween. The frame member is fixed at each end to a respective frame component and is configured to bear a portion of the load supported by the frame assembly. In some applications, frame components may include stressed engine members, such as a crankcase.
