Multi-Pivot Motorcycle Footrests for Off-Road Standing Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motorcycle footrest arrangements, particularly for off-road use, often result in rider instability and fatigue due to the limited surface area of single foldable footpegs, which can lead to ankle injuries and difficulty in shifting weight during riding, especially on challenging terrain.
Innovation Solution
A footrest arrangement featuring two or more individually pivotable footrest devices with internal spacing, allowing riders to stand on one or more surfaces simultaneously, providing increased stability and support, and enabling easier weight redistribution by adding foldable footrest devices behind the original ones, maintaining safety functions and compatibility with kick starters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a single foldable footpeg is used, then the motorcycle maintains foldable safety functionality, but the rider experiences instability and fatigue due to limited support surface area
Solution Approach 1:
The footrest arrangement is divided into multiple independent footrest devices (first and second footrest devices) that can pivot independently around separate pivot axes. Each footrest device provides its own footrest surface, creating multiple discrete support points that together offer greater total support area while maintaining individual foldability for safety.
Solution Approach 2:
The footrest surfaces are arranged in a spatial configuration that extends in multiple dimensions - not just laterally but also in depth and vertical positioning. This three-dimensional arrangement of multiple footrest surfaces provides comprehensive support across different planes, increasing the effective support volume and area available to the rider.
2Stability of the object's composition
If footpegs are made wider to enhance stability, then rider stability improves, but the foldable safety functionality is compromised
Solution Approach 1:
Instead of making a single footpeg wider, the solution segments the support function into multiple separate footrest devices. Each device maintains its own pivot axis and foldable capability, allowing individual adaptation and safety folding while collectively providing enhanced stability through combined support surfaces.
Solution Approach 2:
The footrest devices are designed with dynamic pivot capabilities around slanted pivot axes, allowing them to fold upward and backward when impacted. This dynamic response maintains safety functionality while the multiple devices working together provide continuous stability support during normal riding.
3Stability of the object's composition
If a footboard is used instead of footpegs, then standing stability improves, but the kick starter arrangement cannot be used
Solution Approach 1:
The continuous footboard surface is segmented into discrete, separated footrest devices with gaps between them. This segmentation allows the kick starter pedal to pass through or between the footrest devices, maintaining compatibility with kick starter arrangements while still providing stable support surfaces for the rider's feet.
Solution Approach 2:
The problematic continuous footboard structure is extracted and replaced with individual footrest devices. This removal of the continuous surface eliminates the conflict with kick starter mechanisms while preserving the essential function of providing stable foot support through the remaining discrete devices.
4Reliability
If footrest devices are extended rearwards to provide heel support, then ankle injury protection improves, but the foldable functionality is limited by geometric constraints
Solution Approach 1:
The support function is segmented into multiple footrest devices positioned at different locations and angles. This allows the rearward-extending devices to provide heel support and ankle protection without being constrained by the geometric limitations of a single extended structure, as each device can independently pivot and fold.
Solution Approach 2:
Additional footrest surfaces are positioned in rearward and downward orientations, creating a multi-level support structure. This three-dimensional arrangement provides heel support and ankle protection in vertical and rearward dimensions while maintaining foldable capability through independent pivot axes.

AI summary
A footrest arrangement is for a motorcycle, wherein the footrest arrangement comprises at least two or more individually pivotable footrest devices with footrest surfaces placed with an internal spacing between them so a motorcycle rider can choose whether to rest his foot on one or more of the footrest surfaces simultaneously.
