Foot Peg Elevational System for Two-Wheeled Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-wheeled vehicle footpeg systems lack an efficient mechanism to adjust the position of footpegs relative to the seat reference point, especially when forces are applied to the footpegs, without using cable members.
Innovation Solution
A two-wheeled vehicle footpeg elevational system that includes a first and second footpeg pivotally coupled to the vehicle, with a coupling mechanism that allows the distal end of the first footpeg to move closer to the seat reference point when the second footpeg experiences a greater force, without using cable members. This system utilizes arm assemblies and a gear train to achieve the positional adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cable members are used to couple the first footpeg with the second footpeg, then the footpegs can be positioned relative to each other, but the device complexity increases and the reliability decreases due to additional components
Solution Approach 1:
The patent removes cable members from the footpeg coupling system entirely. Instead of using cables to connect the first and second footpegs, the invention uses a direct mechanical linkage through arm assemblies that are pivotally coupled to the vehicle frame, eliminating the need for flexible cable connections while achieving the same positional control function.
Solution Approach 2:
The patent combines the positioning function previously achieved by separate cable members into an integrated mechanical linkage system. The arm assemblies serve both as structural support and as the coupling mechanism between footpegs, merging multiple functions into unified components that reduce overall system complexity.
2Ease of operation
If cable members are used to couple the first footpeg with the second footpeg, then the footpegs can be positioned relative to each other, but the reliability decreases due to more potential failure points
Solution Approach 1:
The patent removes cable members from the footpeg coupling system entirely. Instead of using cables to connect the first and second footpegs, the invention uses a direct mechanical linkage through arm assemblies that are pivotally coupled to the vehicle frame, eliminating the need for flexible cable connections while achieving the same positional control function.
3Device complexity
If a mechanical coupling mechanism without cable members is used, then the device complexity is reduced and reliability is improved, but the ability to adjust footpeg position becomes more difficult to achieve
Solution Approach 1:
The patent employs pivotally coupled arm assemblies that can rotate and adjust their angles dynamically. The first and second arm assemblies are connected through a mechanical linkage that allows automatic adjustment of footpeg positions based on applied forces, providing adaptability without requiring complex actuation mechanisms. The pivotal connections enable the system to adapt to different riding conditions and force applications.

AI summary
For a self-propelled two-wheeled vehicle including a seat with a reference point, a footpeg elevational system includes a first footpeg pivotally couplable to the self-propelled two-wheeled vehicle, and a second footpeg pivotally couplable to the self-propelled two-wheeled vehicle, wherein the first footpeg is coupled to the second footpeg so that when the first footpeg and second footpeg are pivotally coupled to the self-propelled two-wheeled vehicle, the first footpeg becomes closer to the reference point of the seat of the self-propelled two-wheeled vehicle when the second footpeg becomes farther from the reference point without use of at least one cable member to couple the first footpeg with the second footpeg. In addition, other aspects are described in the claims, drawings, and text forming a part of the present disclosure.
