Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote-controlled toy vehicles have limited steering angles and complex steering structures, lacking omnidirectional adjustment and requiring complex motor control for fine-tuning.
Innovation Solution
An omnidirectional adjustable steering mechanism with steering means comprising a pivot rod, connecting rod, swivelable member, and wheel bracket, allowing independent control of front and rear wheels, enabling 360° swiveling of wheels via lateral movement of the connecting rod, and using servo drives for convenient angle adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional steering mechanisms are used, then the structure is simple, but the steering angle is limited to 18-25°
Solution Approach 1:
The patent employs dynamic linkage mechanisms where the connecting rod connects the steering motor to the wheel brackets through swivelable members. This dynamic structure allows the steering angle to vary continuously from 0° to 360°, replacing fixed-angle traditional steering mechanisms and enabling omnidirectional movement capability.
Solution Approach 2:
The steering system is divided into independent steering means for front wheels and rear wheels, each with its own steering motor, connecting rod, and wheel bracket assembly. This segmentation allows independent control of each wheel's steering angle, achieving complex omnidirectional steering patterns through coordinated operation of multiple segmented steering units.
2Adaptability or versatility
If multiple motors are used to independently drive each wheel, then omnidirectional steering is achieved, but the control complexity increases significantly
Solution Approach 1:
The patent combines the steering control function into a centralized steering motor that drives multiple wheels through a shared connecting rod mechanism. Instead of requiring independent control of multiple wheel motors, the merged steering system allows a single steering input to coordinate all wheel movements, dramatically simplifying the control operation while maintaining omnidirectional capability.
Solution Approach 2:
The connecting rod serves multiple functions simultaneously: it transmits steering motion from the steering motor to multiple wheel brackets, enables angular adjustment for different steering patterns, and coordinates the movement of multiple wheels. This multi-functionality reduces the need for separate control systems for each wheel, making the overall system easier to operate.
3Adaptability or versatility
If increased steering angle mechanisms are used, then wheel turning angle reaches 45°, but the structure occupies significant space
Solution Approach 1:
The patent utilizes spatial arrangement in multiple dimensions to achieve large steering angles in a compact footprint. The swivelable members and connecting rods are arranged in three-dimensional space around the wheel hubs, allowing the steering mechanism to achieve 360° rotation capability without requiring a large planar area, thus reducing the overall volume occupied by the steering system.
Solution Approach 2:
The steering mechanism components are nested around the wheel assemblies, with the connecting rods and swivelable members positioned in the radial and axial spaces surrounding the wheels. This nesting arrangement allows the steering mechanism to achieve full steering angle range while occupying minimal additional space beyond the wheel envelopes.
