Parking Robot Height-Adjustable Running Gear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking robots designed to raise transportation vehicle wheels face challenges with high slippage and inability to navigate steps due to the use of Mecanum wheels, which are not suitable for uneven terrain and require complex designs.
Innovation Solution
A parking robot with a holding device and height-adjustable running gear using driven rollers or simple wheels, equipped with drive installations on opposite sides, allowing for omnidirectional movement and adjustable ground clearance to lift transportation vehicle wheels autonomously, enabling navigation of ramps and uneven surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Mecanum wheels are used for omnidirectional movement, then the parking robot can move in all directions without mechanical steering, but the wheels experience high slippage and cannot negotiate steps or uneven terrain
Solution Approach 1:
The parking robot is divided into multiple independent drive installations, each with simple wheels or rollers. Instead of relying on a single complex Mecanum wheel system, the robot segments its movement capability across multiple simple wheel units positioned at different locations, achieving omnidirectional movement through coordinated operation of these segmented components while maintaining reliability on uneven terrain
Solution Approach 2:
The parking robot employs height-adjustable running gear that can dynamically adapt to uneven terrain and steps. The running gear adjusts its height and configuration in real-time to maintain contact with the ground and negotiate obstacles, transforming the static wheel system into a dynamic one that responds to terrain variations
2Reliability
If simple wheels or rollers are used instead of Mecanum wheels, then the parking robot can navigate uneven terrain and steps, but achieving omnidirectional movement becomes more complex
Solution Approach 1:
The patent combines multiple simple wheel drive installations with height-adjustable running gear into an integrated system. By merging the simplicity of basic wheels with the adaptability of adjustable running gear, the system achieves both terrain navigation capability and omnidirectional movement without requiring complex Mecanum wheel mechanisms
Solution Approach 2:
The drive installations with height-adjustable running gear serve multiple functions: they provide propulsion, enable steering, negotiate terrain variations, and allow height adjustment. This multi-functionality eliminates the need for separate Mecanum wheels designed specifically for omnidirectional movement, simplifying the overall device while maintaining capability
3Length of moving object
If the parking robot has a low construction height to fit under transportation vehicles, then it can access tight spaces, but the running gear height adjustment range is limited
Solution Approach 1:
The running gear incorporates height adjustment mechanisms that allow the construction height to be dynamically changed. The system can transition from a low construction height configuration for accessing tight spaces to a higher configuration for negotiating terrain obstacles, making the static dimension dynamic and adaptable to different operational requirements
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 solution allows for efficient and autonomous transportation of vehicles across varied terrain without the need for complex Mecanum wheels, ensuring stable and space-saving design, and enabling the parking robot to handle uneven surfaces and tight parking spaces.
Implementation Method 1
The running gear is configured for adjusting the holding device relative to the at least one parking robot wheel between a lowered position and a raised position

AI summary
A parking robot for a transportation vehicle having a holding device for firmly holding a wheel of the transportation vehicle and housing at least one drive installation on two opposite sides. The drive installation has a height-adjustable running gear having at least one parking robot wheel and adjusts the holding device relative to the at least one parking robot wheel between a lowered and a raised position. The parking robot autonomously moves to a receiving position on the wheel of the transportation vehicle, in which receiving position the holding device firmly holds the wheel, and by adjusting the holding device to the raised position by the running gear, raises the firmly held wheel of the transportation vehicle relative to the respective parking robot wheels.
