Solution Overview

Problem

Conventional motorcycle foot pegs cause injuries due to abrupt impacts, vibration trauma, and lack of flexibility, leading to micro-trauma, bruising, tendon pain, and potential nerve damage or arthritis, as they fail to maintain consistent contact with the rider's boots, especially in off-road conditions.

Innovation Solution

A foot peg design featuring a platform with a vibration-isolating bushing system that separates the foot peg platform from the motorcycle frame, using a variable bushing with a vibration-reducing material to absorb impacts and vibrations, ensuring consistent contact and improved grip.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional rigid foot pegs are used, then structural strength and stability are maintained, but vibratory trauma and impact injuries occur to the rider's feet

Engineering Contradiction:

Improvefoot peg structural strengthVSAvoidvibratory trauma to rider's feet

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

A vibration isolating bushing is introduced as an intermediary component between the foot peg platform and the motorcycle frame. This bushing acts as a mediator that transmits necessary mechanical support while filtering out harmful vibrations and impacts, preventing them from reaching the rider's feet.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The foot peg assembly uses a composite structure combining rigid materials for the platform and mounting components with a compliant vibration isolating bushing. This composite approach allows the rigid elements to provide structural strength while the compliant bushing material absorbs vibrations and impacts.

Inventive Principle:

Principle #40Composite materials

2Ease of manufacture

If conventional rigid foot pegs are used, then manufacturing simplicity is maintained, but flexibility and adaptability to terrain are reduced

Engineering Contradiction:

Improvefoot peg manufacturing simplicityVSAvoidfoot peg flexibility on uneven terrain

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The vibration isolating bushing serves as a flexible intermediary that adapts to uneven terrain conditions. It provides the necessary compliance and flexibility to maintain contact with the rider's boot on varied surfaces while remaining relatively simple to manufacture as a standard bushing component.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If conventional foot pegs without vibration isolation are used, then device complexity is minimized, but rider comfort and control are reduced

Engineering Contradiction:

Improvefoot peg assembly complexityVSAvoidrider comfort and control

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The vibration isolating bushing is a relatively simple intermediary component that can be integrated into existing foot peg assemblies without requiring complex mechanisms. It provides effective vibration isolation and improved rider comfort while adding minimal complexity to the overall device.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A motorcycle foot peg (10) constructed to help isolate a rider from vibration and impact forces normally transmitted through a solid foot peg. The isolating foot peg is applicable for on and off road use where prolonged vibration or discrete impacts may cause injury. The foot peg has an adaptable rigid mounting platform (11) from which a rigid foot peg supporting shaft (19) projects outward in a cantilevered fashion. The supporting shaft is inserted through an internal aperture (34) and secured to an internal rigid tube (29) of a bushing (27). The bushing filled with a vibration isolating material (32) externally is secured to a receiver (23), which is incorporated into a foot peg platform (22). The foot peg platform (22) is thereby isolated from the supporting shaft (19) and motorcycle frame (12) by vibration damping material (32) with in the bushing (27). This relationship allows for reduction of vibratory forces that would normally be transmitted to the rider through a conventional solid Foot peg platform.
