Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current four-wheeled vehicles, such as cars and toy cars, have limited steering capabilities, making parallel parking difficult and prone to collision, and lack versatility in driving styles, complicating steering operations and reducing playability.
Innovation Solution
An omnidirectional vehicle design featuring a chassis with wheel steering mechanisms that allow each wheel to rotate 180° or more, utilizing a swing arm and arcuate guiding groove for omnidirectional movement, enabled by drive motors and gears for simplified steering and synchronization of wheel movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional wheel steering mechanisms are used with limited rotation angles, then the vehicle structure remains simple, but the steering capability is insufficient and parallel parking is difficult
Solution Approach 1:
The patent applies dynamics by making the wheel steering mechanism movable and adjustable. The swing arm allows the wheel to rotate dynamically to various angles including 180 degrees, enabling the steering mechanism to adapt to different driving conditions and achieve omnidirectional movement capability.
Solution Approach 2:
The wheel steering mechanism is segmented into independent components: a swing arm pivotally connected to the chassis, and a wheel connected to the swing arm. This segmentation allows each component to move independently, enabling the wheel to achieve 180-degree rotation and omnidirectional steering capability.
2Reliability
If front wheels are limited to small angle turns, then the vehicle structure is simple, but collision accidents容易发生 and playability is reduced
Solution Approach 1:
The swing arm enables dynamic adjustment of wheel steering angles, allowing wheels to turn to optimal angles for avoiding collisions and performing maneuvers. This dynamic steering capability improves safety and playability compared to fixed small-angle steering.
Solution Approach 2:
The patent changes the steering angle parameter from conventional small angles to 180 degrees or more. This parameter change enables the vehicle to perform parallel parking, avoid collisions, and execute various driving styles, thereby improving safety and playability.
3Ease of operation
If rear wheels cannot turn, then the vehicle structure is simple, but parallel parking is difficult and steering operation is complicated
Solution Approach 1:
Each wheel is equipped with an independent swing arm steering mechanism, allowing each wheel to be steered independently. This segmentation enables complex maneuvers like parallel parking and omnidirectional movement while simplifying steering operation through independent wheel control.
Solution Approach 2:
The swing arm mechanism provides dynamic steering capability to each wheel, allowing the vehicle to execute complex maneuvers such as parallel parking and omnidirectional movement. This dynamic steering simplifies steering operation compared to conventional vehicles with restricted wheel movement.

AI summary
A omnidirectional vehicle includes a chassis, wheels and wheel steering mechanisms. The wheel steering mechanisms are configured between the chassis and the wheels, and are arranged to drive the wheels to rotate about a steering center shaft of each wheel with 180° or more. The omnidirectional vehicle can achieve longitudinal driving and lateral driving, or other driving manners.
