Three-Wheel Vehicle Rear Frame Layout for Nested Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric three-wheeled vehicles require large parking spaces when multiple vehicles are parked together, making efficient parking in limited spaces challenging.
Innovation Solution
The design includes a single front wheel and a pair of rear wheels with support frames that can be separated to allow another vehicle to be inserted between them, enabling efficient parking by shortening the overall length and allowing vehicles to be coupled and towed together, with a locking mechanism to stabilize the vehicles during parking.

Engineering Contradiction Analysis
1Area of stationary object
If multiple vehicles are parked in a conventional configuration, then each vehicle has sufficient structural stability, but the parking space required increases significantly
Solution Approach 1:
The vehicle is divided into separable components with front and rear connection portions that can be detached. The support frames are designed to be separable, allowing the vehicle to be split into front and rear sections for compact parking arrangement while maintaining structural integrity during operation
Solution Approach 2:
Vehicles are arranged in a nested configuration where the front wheel of one vehicle fits into the gap between support frames of the vehicle in front, creating a compact stacked parking arrangement that minimizes the overall space occupied by multiple vehicles
2Area of stationary object
If the support frames are separated to allow vehicle insertion, then parking efficiency improves, but vehicle structural stability deteriorates
Solution Approach 1:
The support frames are designed with dynamic characteristics, allowing them to be in a separated state during parking operations and a connected/locked state during vehicle operation. The connection portions can be quickly transitioned between connected and disconnected states to adapt to different operational requirements
Solution Approach 2:
The connection portions are pre-configured with coupling mechanisms that automatically engage when vehicles are positioned for parking, and locking mechanisms are pre-arranged to secure the connected state before vehicle operation begins, ensuring stability is established in advance

AI summary
A vehicle (100) includes a front wheel (1), a pair of left and right rear wheels (2) disposed diagonally behind the front wheel (1) on a left side and a right side, and a pair of left and right support members (21) extending in a front-rear direction and including support portions (23) rotatably supporting the pair of left and right rear wheels (2). The pair of left and right support members (21) are disposed so as to be separated from each other by a predetermined distance so that a front wheel (1) of another vehicle (100) configured to have a same shape as the vehicle (100) is insertable into a gap between the pair of left and right support members (21) from a rear side.
