Reverse Drive Mechanism for Motorcycle Conversion Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motorcycle conversion kits to tricycles face challenges such as the need for rear wheel removal, complex assembly, and difficulty in reversing the vehicle, especially for riders who are uncomfortable on two wheels or need additional stability.
Innovation Solution
A reverse drive mechanism is integrated into a conversion assembly for motorcycles, allowing at least one rear wheel to be driven in reverse, enabling the motorcycle to back up without requiring wheel removal or extensive assembly, and can be powered by an automotive starter motor with a gear system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional tricycle conversion assemblies are used, then stability and cargo capacity are improved, but the ability to reverse the vehicle is lost
Solution Approach 1:
The patent combines the reverse drive mechanism with the existing conversion assembly by integrating a motor and gear system that couples to the rear axle. This merging allows the conversion assembly to provide both stability enhancement and reverse drive capability through a unified structure rather than separate components.
Solution Approach 2:
The conversion assembly is designed to serve multiple functions: it provides structural stability through the rear axle and wheels, enables reverse motion through the integrated motor and gear system, and maintains compatibility with the original motorcycle drive system. This multi-functionality resolves the contradiction by making the assembly both stabilizing and reversible.
2Stability of the object's composition
If conversion assemblies require extensive connection to the motorcycle, then stability is improved, but ease of attachment and detachment is reduced
Solution Approach 1:
The conversion assembly is segmented into modular components including the rear axle assembly, wheel assemblies, and the reverse drive mechanism with motor and gear system. This segmentation allows for easier attachment and detachment while maintaining stability, as each module can be independently installed and removed without requiring complete disassembly of the entire system.
3Ease of operation
If the reverse drive mechanism is added to the conversion assembly, then reverse maneuverability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a gear system as an intermediary mechanism between the motor and the rear wheel. This gear intermediary simplifies the overall system by providing a compact way to transfer motor power to the wheel while managing the complexity through a well-understood mechanical transmission approach, rather than requiring direct motor-to-wheel coupling or complex control systems.

AI summary
A reverse drive mechanism is configured to rotate at least one wheel of a multi-wheeled device in a reverse direction so that the device moves in that reverse direction. One particular application involves a motorcycle conversion assembly in which at least one of the rear wheels of the conversion assembly is driven in the reverse direction so as to back-up the motorcycle.
