Solution Overview
Problem
Current three-wheeled motorized vehicles fail to balance efficiency, cost-effectiveness, safety, and styling, lacking a strong value proposition and struggling to achieve high-volume production due to excessive price, width, improper styling, and inadequate safety and comfort.
Innovation Solution
A modular, customizable three-wheeled motorized vehicle design featuring a chassis with a front and rear portion, rear axle assembly that adjusts between retracted and extended positions for stability, electric drive motors, and a tilting mechanism for enhanced handling, combined with modular bodywork and safety features to address the limitations of existing vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the vehicle uses a fixed wide rear axle assembly, then stability is improved, but the vehicle width increases making it difficult to park and lane-split
Solution Approach 1:
The rear axle assembly is designed to dynamically change its width, extending outward to provide stability during straight-line travel and retracting inward to reduce vehicle width for parking and lane-splitting maneuvers. This dynamic adjustment allows the vehicle to adapt its physical dimensions based on operational requirements.
Solution Approach 2:
The rear axle assembly is segmented into movable components that can independently adjust their position. The axle assembly includes extendable arms or members that can be deployed outward to increase track width for stability, then retracted to minimize overall vehicle width when stability is not required.
2Quantity of substance
If the vehicle is designed to carry multiple passengers, then passenger capacity is improved, but energy efficiency decreases and vehicle size increases
Solution Approach 1:
The vehicle is designed with modular seating configurations that can accommodate different numbers of passengers based on operational needs. The same vehicle platform can function as a single-passenger efficient mode or expand to carry multiple passengers when required, making the vehicle versatile rather than specialized for one capacity level.
Solution Approach 2:
The vehicle incorporates dynamically adjustable seating and cargo areas that can be expanded or contracted. When carrying multiple passengers, the vehicle can extend its usable space; when carrying one passenger, the vehicle maintains a compact, energy-efficient configuration.
3Ease of operation
If the vehicle uses a narrow fixed chassis, then ease of parking and lane-splitting is improved, but stability at higher speeds deteriorates
Solution Approach 1:
The vehicle employs a dynamically adjustable rear axle assembly that extends outward when high-speed stability is required and retracts when narrow maneuverability is needed. This allows the vehicle to optimize its stability characteristics based on whether it is engaged in high-speed travel or low-speed maneuvering.
Solution Approach 2:
The vehicle changes its physical parameters (specifically track width via the rear axle assembly) based on operational conditions. The system monitors vehicle speed and maneuvering requirements, then adjusts the rear axle width parameter accordingly to maintain optimal stability across different operating regimes.
4Stability of the object's composition
If the vehicle uses a complex stabilizing mechanism, then stability control is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The vehicle replaces complex mechanical stabilizing mechanisms with electronic control systems and actuators. The rear axle assembly is positioned using electric motors or hydraulic actuators controlled by sensors and microprocessors, eliminating the need for complex mechanical linkages, springs, and dampers that would otherwise be required for active stability control.
Solution Approach 2:
The stabilizing system uses sensors to automatically detect vehicle state and conditions, then self-adjusts the rear axle position without requiring complex mechanical feedback mechanisms. The electronic control system monitors and corrects stability issues automatically, reducing mechanical complexity while maintaining effective stability control.
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 design achieves a balance of efficiency, cost-effectiveness, safety, and styling, enabling highway-capable speeds, lane-splitting capability, and easy parking while offering a better value proposition than traditional four-wheeled vehicles or motorcycles, with the ability to incrementally upgrade and customize the vehicle platform.
Implementation Method 1
The linear actuator also includes a pinion in communication with prime mover and the gear rack of each of the first rear wheel axle and the second rear wheel axle. A rotation of the pinion by the prime mover causes the first rear wheel axle and the second rear wheel axle to move between the retracted position and the extended position.

AI summary
A three-wheeled vehicle includes a vehicle frame supported by a single wheel engaging the ground in the front and two wheels engaging the ground in the rear. The operator area of the vehicle may include seating for a driver and a passenger, one in front of the other. The three-wheeled vehicle is uniquely designed so that it can be easily modified by addition or removal of additional structures after it is purchased. The vehicle is ultra-narrow but achieves stability by unique mechanisms.
