Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional two-wheeled toy vehicles, such as toy motorcycles, often require additional training wheels to maintain balance and lack advanced features to simulate complex maneuvers like drifting and wheelies, failing to meet heightened user expectations from modern media.
Innovation Solution
A self-balancing two-wheeled vehicle design featuring a body with a first and second wheel, where the second wheel has lateral rollers rotating obliquely or orthogonally to its axis, coupled with motors and sensors to control orientation and movement, and a control module that receives operational commands from a remote control unit to maintain balance and perform maneuvers like wheelies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional two-wheeled toy vehicles are designed without training wheels, then the vehicle structure becomes simpler and more realistic, but the vehicle cannot maintain balance in an upright position
Solution Approach 1:
The vehicle uses self-balancing technology with sensors and motors to automatically maintain its upright position without requiring external support structures like training wheels. The system continuously monitors its orientation and adjusts wheel torque to counteract tipping forces, enabling the vehicle to balance itself autonomously.
Solution Approach 2:
The patent replaces the mechanical support structure of training wheels with an electronic control system comprising sensors (accelerometers, gyroscopes), control modules, and motor actuators. This substitution allows the vehicle to maintain balance through active control rather than passive mechanical support.
2Stability of the object's composition
If traditional two-wheeled toy vehicles are equipped with training wheels, then the vehicle can maintain balance, but the vehicle cannot perform complex maneuvers like drifting and wheelies
Solution Approach 1:
The vehicle autonomously performs complex maneuvers such as wheelies and drifting by using its self-balancing control system to dynamically adjust wheel torques and body orientation. The system monitors its state via sensors and executes coordinated motor commands to achieve and maintain desired maneuver states without external intervention.
Solution Approach 2:
The patent implements dynamic control of wheel torques and lateral roller positions to enable the vehicle to transition between different operational states (normal riding, wheelie, drifting). The control system continuously adapts motor commands based on real-time sensor feedback to maintain balance and execute maneuvers.
3Adaptability or versatility
If self-balancing technology with motors and sensors is added to the vehicle, then the vehicle can balance upright and perform complex maneuvers, but the device complexity increases
Solution Approach 1:
The control system is designed to perform multiple functions: maintaining balance, executing wheelies, enabling drifting, and responding to remote control commands. By integrating these capabilities into a single unified control architecture, the patent reduces overall system complexity compared to having separate systems for each function.
Solution Approach 2:
The system uses sensor feedback (accelerometers, gyroscopes, wheel encoders) to continuously monitor vehicle state and adjust motor commands in real-time. This closed-loop control enables the system to handle multiple maneuvers with a unified control strategy, reducing the need for complex separate control systems for each function.
