Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transformable toy vehicles cannot dynamically transform from a standing position to a flying position like a helicopter and then to a driving position like a wheeled vehicle while maintaining stability and center of gravity, and they lack the ability to be controlled remotely during flight and to land in multiple positions.
Innovation Solution
A transformable toy vehicle design featuring a main upper body portion, a lower body portion, a rotating blade system with counter-rotating blades, and a vehicle control unit with a micro-processor and receiver for remote control signals, allowing for automatic transformation between standing, flying, and driving modes while maintaining stability and enabling steering in both flight and driving modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the toy vehicle is designed to transform between standing, flying, and driving modes, then the versatility and adaptability of the toy is improved, but the device complexity increases significantly
Solution Approach 1:
The toy vehicle is divided into distinct functional modules: a lower body portion with legs for standing mode, an upper body portion with rotating blade system for flying mode, and wheeled assemblies for driving mode. Each module can be independently controlled and transformed, managing overall system complexity through modular design
Solution Approach 2:
The lower body portion serves multiple functions: it provides structural support in standing mode, houses the center of gravity adjustment mechanism for flight stability, and contains the drive system for both transformation and ground movement. The upper body portion similarly serves as both the flying platform and the driving cabin, eliminating the need for separate structures for each mode
2Ease of operation
If the toy vehicle transforms dynamically while in flight, then the ease of operation is improved, but the stability of the object deteriorates
Solution Approach 1:
The center of gravity is pre-adjusted to an optimal position within the lower body portion before flight begins. This preliminary positioning ensures that when the vehicle transforms from standing to flying mode, the center of gravity remains in a stable position relative to the rotating blades, maintaining flight stability throughout the transformation sequence
Solution Approach 2:
The vehicle employs dynamic center of gravity adjustment mechanisms that can shift weight distribution in real-time during flight. This allows the system to compensate for stability changes that occur during transformation, enabling remote-controlled mode changes while maintaining flight stability through active balance control
3Ease of operation
If the toy vehicle uses counter-rotating blades for steering, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The vehicle uses two counter-rotating blades that rotate in opposite directions at potentially different speeds. This asymmetric rotation capability provides intuitive steering control: increasing speed of one blade while decreasing the other creates a turning moment, enabling simple directional control without complex mechanical steering mechanisms
Solution Approach 2:
The patent replaces traditional mechanical steering systems with aerodynamic control through differential blade rotation. Instead of using mechanical linkages or movable control surfaces, the vehicle steers by electronically controlling the rotation speed of each blade independently, simplifying the mechanical structure while improving response time and control precision
