Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single-wheeled self-balancing vehicles are difficult to balance and control, while two-wheeled vehicles require simultaneous hand and foot operation, leading to instability and safety concerns during turning.
Innovation Solution
A self-balancing vehicle frame equipped with two angle sensors and wheels that rotate to maintain balance, featuring a front frame assembly with rotatable units and connecting mechanisms allowing independent control of each wheel, enabling users to operate the vehicle using pedals and handles for balanced movement and turning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-wheeled self-balancing vehicle is used, then the vehicle structure is simple, but the vehicle is difficult to balance and control
Solution Approach 1:
The vehicle is divided into two independent wheel units, each with its own angle sensor and control system. This segmentation allows each wheel to be independently controlled, improving balance and control capability while maintaining relatively simple overall structure
Solution Approach 2:
The patent combines the functions of two single-wheeled vehicles into one integrated two-wheeled vehicle system, merging the balance control and propulsion functions into a unified platform that leverages the advantages of multiple wheels while maintaining operational simplicity
2Ease of operation
If a two-wheeled self-balancing vehicle with a middle handle is used, then the vehicle can overcome single-wheeled balance issues, but the user must use hands and feet to operate simultaneously
Solution Approach 1:
The patent removes the middle handle component from the vehicle design, extracting the obstruction that required simultaneous hand and foot operation. This allows users to control the vehicle more naturally without the constraint of operating multiple controls at once
Solution Approach 2:
Instead of requiring the user to actively manipulate a middle handle for balance control, the system inverts the approach by using angle sensors mounted on the user's body to automatically detect tilt and control the wheels, transforming manual control into automatic sensor-based control
3Ease of operation
If a two-wheeled self-balancing vehicle is used, then balance control is improved, but excessive pulling force on the middle handle during turning causes overturning
Solution Approach 1:
By removing the middle handle entirely, the patent eliminates the source of excessive pulling force that caused overturning during turns. The handleless design prevents users from applying destabilizing forces while maintaining balance control through sensor-based wheel adjustment
Solution Approach 2:
The vehicle performs self-balancing through angle sensors that automatically detect user tilt and adjust wheel rotation accordingly, eliminating the need for manual handle manipulation and reducing the risk of user-induced instability during turning maneuvers
4Ease of operation
If a two-wheeled self-balancing vehicle with a middle handle is used, then balance control is improved, but it is difficult for the user to jump away through the front of the vehicle
Solution Approach 1:
The patent removes the middle handle that obstructed the user's path during emergency escape. Without this central obstruction, users can more easily jump away from the vehicle in front, eliminating the safety hazard while preserving balance control functionality
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
Facilitates easier control and stability of the vehicle, allowing users to operate it with hands and feet, reducing the risk of overturning and enabling safe jumping away from the vehicle.
Implementation Method 1
a controller that receives a tilt angle signal from the tilt angle sensor and outputs a control signal to the motor
Implementation Method 2
a motor that rotates in response to a control signal from the controller and drives the wheel
Implementation Method 3
Each of the wheels is controlled to rotate for maintaining a corresponding one of the angle sensors in a balanced state in response to tilt of the corresponding one of the angle sensors

AI summary
A self-balancing vehicle frame is mounted with two angle sensors and two wheels that are electrically and respectively coupled to the angle sensors, and includes a front frame assembly that includes two front frame units and a first connecting unit. The front frame units cooperatively define a connecting space therebetween. Each of the front frame units is mounted with a respective one of the wheels and a respective one of the angle sensors, and is operable to tilt the corresponding one of the angle sensors. The first connecting unit is located in the connecting space, and interconnects the front frame units such that the front frame units are rotatable relative to each other.
