Motorcycle Forearm Shin Glider With Ceramic Rolling Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle gliders for high-speed cornering suffer from significant friction between the rider's forearm and shin and the road surface, leading to reduced cornering speed, rider discomfort, and instability.
Innovation Solution
The development of a forearm and shin glider featuring abrasion-resistant ceramic balls housed in ceramic bearings, mounted within a deformable casing with slits for secure fitment, and equipped with air ducts for cooling, significantly reduces friction while maintaining support during high-speed cornering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic molding protection devices are used for ground contact during cornering, then rider protection is provided, but substantial friction is generated causing rider discomfort and reduced cornering speed
Solution Approach 1:
The patent changes the material parameter from plastic molding to ceramic balls with low friction coefficient. The ceramic balls reduce the friction coefficient between the ground contact surface and road, directly addressing the harmful friction effect while maintaining protection functionality.
Solution Approach 2:
The patent uses composite structure combining ceramic balls embedded in a polymer matrix material. This composite provides both the low friction properties of ceramic and the protective cushioning of polymer, resolving the contradiction between protection and friction reduction.
2Stability of the object's composition
If ground contact is sought for support during cornering, then cornering stability is improved, but the stick-slip braking effect reduces cornering speed
Solution Approach 1:
The patent changes the friction parameter by using ceramic balls instead of plastic surfaces. The low friction coefficient of ceramic allows ground contact for stability without generating the stick-slip braking effect that reduces cornering speed.
3Reliability
If existing plastic protection devices are used, then rider protection is provided, but the devices cause rider discomfort due to friction
Solution Approach 1:
The patent changes the material from plastic to ceramic balls, fundamentally altering the friction parameter. This reduction in friction directly improves rider comfort while the ceramic balls maintain the protective function during ground contact.
4Force
If high friction materials are used for ground contact, then rider support is provided, but cornering speed is reduced due to braking effect
Solution Approach 1:
The patent changes the friction parameter by using ceramic balls with low friction coefficient. This allows the device to provide rider support through ground contact without generating the high friction braking effect that reduces cornering speed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The glider allows riders to achieve higher cornering speeds with reduced friction, enhancing rider comfort and control by minimizing the 'stick-slip' effect, while the durable materials ensure longevity and effective heat management.
Implementation Method 1
The abrasion resistant balls move smoothly within the bearings and casing and roll when contacting the ground, creating minimal friction
Implementation Method 2
The base also includes air ducts to provide cooling air to the device as heat from friction builds up

AI summary
A forearm and shin glider for motorcycle cornering including a deformable base with slits that allow secure and comfortable fit to the rider's arm or leg. An abrasion resistant casing is attached to the base. This casing holds a set of abrasion resistant balls made of high speed smooth abrasion resistant ceramic. The abrasion resistant balls are located by bearings, also manufactured of ceramic. This device allows the rider to make contact with the ground for support during tight cornering maneuvers with substantially reduced and minimized friction. The abrasion resistant balls move smoothly within the bearings and casing and roll when contacting the ground, creating minimal friction but also providing substantial rider support. The glider device includes air ducts for air flow to reduce friction related heat. The glider device is attached to the rider's clothing using Velcro or hook and loop attachment devices.
