Three-Wheel Vehicle Layout for Nested Compact Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric three-wheeled vehicles require a large parking space when multiple vehicles are parked together, making efficient parking in limited spaces challenging.
Innovation Solution
A vehicle configuration with a front wheel and a pair of diagonally positioned rear wheels, featuring support members that allow another vehicle to be inserted between them, reducing the overall length and enabling efficient parking in limited spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional electric three-wheeled vehicle configuration is used, then the vehicle structure is simple and easy to manufacture, but a large parking space is required when multiple vehicles are parked
Solution Approach 1:
The patent applies dimensionality change by transitioning from a traditional longitudinal vehicle arrangement to a diagonal wheel configuration. The rear wheels are positioned at diagonal corners relative to the front wheel, creating a compact triangular wheelbase that reduces the vehicle's length in the front-rear direction. This allows vehicles to be parked more efficiently in limited spaces while maintaining structural simplicity and ease of manufacture.
Solution Approach 2:
The patent implements nesting by allowing the front wheel of one vehicle to be inserted into the gap between the diagonal rear wheels of the vehicle in front. This nested arrangement enables multiple vehicles to be parked in a compact configuration where each vehicle partially occupies the space of the previous vehicle, significantly reducing the total parking area required.
2Length of moving object
If the support members are positioned close together, then the vehicle width is reduced, but another vehicle cannot be inserted between the support members
Solution Approach 1:
The patent applies parameter changes by optimizing the distance between diagonal rear wheels and the position of support members. The rear wheels are positioned at diagonal corners with support members extending forward at specific angles and distances. This configuration maintains a compact vehicle width while creating sufficient gap space between support members to accommodate the front wheel of another vehicle, achieving both compact dimensions and parking flexibility.

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