Motorcycle Foot Anchor for Lean Angle Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorcycle riders face limitations in maintaining balance and control during high-speed turns due to the need for increased lean angles, which restricts acceleration and deceleration rates without risking tire traction loss, especially when executing the hanging off technique.
Innovation Solution
The introduction of foot anchors attached to the motorcycle frame, which allow riders to anchor their feet securely, enabling them to shift their body further into the turn without losing contact, thereby reducing the lean angle and enhancing control and speed through turns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the rider shifts body further into the turn to reduce lean angle, then the acceleration and deceleration rates increase, but the rider may lose contact with the motorcycle and fall off
Solution Approach 1:
The foot anchor provides preliminary anchoring of the rider's foot to the motorcycle frame before the rider shifts body weight into the turn. This pre-established connection point ensures the rider maintains secure contact with the motorcycle throughout the body-shifting maneuver, preventing loss of contact and falls while enabling aggressive lean angle reduction and improved acceleration/deceleration rates
Solution Approach 2:
The foot anchor acts as an intermediary element between the rider's foot and the motorcycle frame. This intermediate structure distributes the forces generated during body shifting and turn execution, providing a stable mechanical connection that enhances rider control and prevents direct loss of contact with the motorcycle during aggressive maneuvers
2Speed
If the rider uses the hanging off technique to reduce lean angle, then the speed through turns increases, but the rider must continuously contract hamstring muscles to maintain contact
Solution Approach 1:
The foot anchor enables the rider's foot and lower leg to serve as a stable anchoring point, eliminating the need for continuous active muscle contraction to maintain contact. The mechanical connection provided by the foot anchor allows the rider's body to shift into the turn without requiring sustained hamstring engagement, thereby reducing energy consumption while maintaining turn speed
3Speed
If the rider leans further into the turn to compensate for increased centrifugal force, then the maximum speed through the turn increases, but the required lean angle increases
Solution Approach 1:
The foot anchor enables the rider to utilize a different spatial configuration by anchoring the foot to the motorcycle frame and shifting the upper body into the turn. This dimensional change in body positioning allows the rider to effectively reduce the motorcycle's lean angle while maintaining the necessary centrifugal force balance, thereby achieving higher speeds with reduced lean angles

AI summary
A motorcycle foot anchor includes a foot anchor including a base, a body and an end portion. The base of the foot anchor is coupled to a motorcycle frame. The foot anchor protrudes from the motorcycle frame. A plurality of concentric grooves including pointed edges are disposed on the foot anchor. The pointed edges of the concentric grooves point toward the motorcycle frame. The end portion of the foot anchor has a larger diameter than a diameter of the body of the foot anchor.
