Detachable Rickshaw Trailer Hitch for Stable Electric Tricycles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric tricycles are not well suited for transporting multiple passengers due to limited seating capacity, balance and stability issues, power and performance degradation, legal and safety regulations, and comfort and ergonomic compromises.
Innovation Solution
A detachable rickshaw system is integrated with an electric tricycle, featuring a tow hitch for connecting a trailer with synchronized brake lights and additional seating, which includes a chassis, passenger seats, and a storage compartment, enhancing stability and capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single rider configuration is used, then the electric tricycle maintains optimal balance and stability, but it cannot accommodate multiple passengers
Solution Approach 1:
The system is divided into two independent parts: the electric tricycle and the detachable trailer. The trailer with its own wheel assembly is separated from the tricycle body, allowing the tricycle to maintain its original stable configuration while the trailer provides additional passenger capacity. This segmentation enables the system to accommodate multiple passengers without compromising the tricycle's balance.
Solution Approach 2:
A tow hitch mechanism serves as an intermediary connection between the tricycle and the trailer. This intermediary component allows the trailer to be attached to the tricycle in a manner that does not interfere with the tricycle's stability, enabling the transfer of passengers while maintaining the tricycle's operational characteristics.
2Adaptability or versatility
If additional passengers are added to the tricycle, then seating capacity increases, but the motor and battery are overloaded
Solution Approach 1:
The load is segmented between two separate vehicles: the electric tricycle and the trailer. The tricycle's motor and battery are optimized for their original single-rider configuration, while the trailer provides additional seating capacity. This segmentation prevents overloading the tricycle's power system while accommodating multiple passengers.
3Adaptability or versatility
If the tricycle is designed for single rider operation, then power and performance are optimized, but it cannot safely transport multiple passengers
Solution Approach 1:
The system segments the transportation function into a tricycle for the rider and a trailer for additional passengers. This segmentation allows the tricycle to maintain its optimized single-rider design and safety standards while the trailer provides the necessary capacity for multiple passengers, thereby maintaining reliability and regulatory compliance.

AI summary
An electric tricycle includes a frame; a first wheel, a second wheel, and a third wheel, each of which are connected to the frame; a motor connected to the frame and configured to rotate at least one of the first wheel, the second wheel, or the third wheel so to propel the electric tricycle; and a tow hitch attached to the rear portion of the frame, wherein the tow hitch is configured to connect to a tongue of a trailer. The trailer for use with an electric tricycle includes a chassis; a tongue configured to attached to a tow hitch of the electric tricycle; a passenger seat; a brake light, wherein the brake light is configured to be synchronized with a brake light mounted directly to the electric tricycle.
