Variable Wheeled Vehicle Mode Switching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small-size vehicles require the ability to easily switch between different driving modes to accommodate various driving environments and user preferences, but existing vehicles lack the flexibility to seamlessly transition between two-wheel and three-wheel configurations for efficient high-speed and low-speed operations.
Innovation Solution
A variable wheeled vehicle design featuring a main body with two driving wheels and a controlling wheel part that can switch between two-wheel and three-wheel modes, utilizing a processor to adjust the controlling wheel's position and steering angle based on drive velocity to ensure stability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the vehicle uses a fixed three-wheel configuration for stability, then stability is improved, but speed and maneuverability deteriorate
Solution Approach 1:
The vehicle dynamically changes its wheel configuration between two-wheel mode and three-wheel mode based on driving conditions. The controlling wheel part can be raised or lowered to contact the ground, allowing the vehicle to switch from a stable three-wheel configuration to a faster two-wheel configuration, resolving the contradiction between stability and speed.
2Adaptability or versatility
If the vehicle switches between two-wheel and three-wheel modes, then adaptability is improved, but device complexity worsens
Solution Approach 1:
The vehicle is segmented into a main body and a separate controlling wheel part that can be independently positioned. This segmentation allows the controlling wheel to be raised or lowered to change the vehicle's wheel configuration, enabling mode switching without requiring a completely complex reconfigurable chassis system.
3Stability of the object's composition
If the controlling wheel contacts the ground in three-wheel mode, then stability is improved, but ease of operation worsens due to additional steering control
Solution Approach 1:
The steering functions of the two driving wheels and the controlling wheel are merged into a unified steering system. The steering part simultaneously controls the inclination of the driving wheels and the rotation of the controlling wheel about the vertical direction, allowing the user to operate all steering functions through a single integrated control mechanism.

AI summary
A vehicle includes a main body configured to allow a user to ride on the main body, two driving wheels rotatably coupled to the main body, and a controlling wheel part rotatably coupled to the main body to control a direction of the vehicle in which the main body travels at a specific drive velocity by making contact with a ground surface to rotate about a vertical direction in a three-wheel mode. The main body includes a seat part formed to receive the user in a seated position, a steering part configured to obtain an inclination degree to perform steering based on the inclination degree in which the user seated on the seat part is inclined, in the three-wheel mode, and a post configured to connect the steering part with the seat part.
