Steering Module Linkage for Single-Motor Wheel Tilt and Steering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile robots require separate steering and tilting motors, increasing the number of motors needed and complicating their manufacture.
Innovation Solution
A movable object design that uses a single type of motor to control both rotational and tilting motions through a steering module with interconnected links and a steering drive unit, allowing wheels to steer left or right based on their position relative to the body part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate steering and tilting motors are provided, then the mobile robot can perform rotational motion and tilting motion, but the number of motors increases and manufacturing becomes complicated
Solution Approach 1:
The steering module is designed to perform multiple functions: it controls both the rotational motion (steering angle) and tilting motion (wheel elevation) of the mobile robot. By making the steering module universal, the system can achieve both motion types using a single motor, thereby reducing the total number of motors while maintaining full motion control capability
Solution Approach 2:
The patent merges the previously separate steering control and tilting control functions into a single steering module. The steering motor's rotation is transmitted through a series of links (upper link, lower link, restraining link) that simultaneously control both the steering angle and the elevation angle of the wheel, combining two control functions into one physical component
2Adaptability or versatility
If separate steering and tilting motors are provided, then the mobile robot can perform rotational motion and tilting motion, but the manufacturing process becomes complicated
Solution Approach 1:
The steering module serves as a universal component that handles both steering and tilting operations. This multi-functionality simplifies the manufacturing process by reducing the number of different motor types and control systems that need to be integrated, thereby improving ease of manufacture while maintaining full motion control capability
Solution Approach 2:
By combining the steering and tilting control mechanisms into a single integrated steering module with interconnected links, the patent reduces the number of separate components that need to be manufactured and assembled. This merging of functions directly reduces manufacturing complexity

AI summary
A movable object includes: a body part forming a main body; a wheel provided on a left side or a right side of the body part; a steering module connecting the body part and the wheel, wherein the steering module controls movement of the wheel in a manner that steers the wheel to the left when the wheel moves upward with respect to the body part, and steers the wheel to the right when the wheel moves downward with respect to the body part.
