Electric Vehicle Swinging Control via Angle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicles, such as caster boards, are inconvenient to control as they often require manual switching or remote control to turn on, limiting user experience and ease of operation.
Innovation Solution
An electric vehicle design incorporating a carrier, free-wheel unit, foot-wheel unit, driving unit, angle-detecting unit, micro processing unit, and voice prompting unit, where the driving unit is activated by a swinging signal from the free-wheel unit, allowing users to easily turn on the vehicle by swinging the free-wheel unit, enabling convenient power control and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual switching or remote control is used to turn on the electric vehicle, then the driving unit can be activated, but the operation becomes inconvenient and complex
Solution Approach 1:
The electric vehicle automatically detects when the user stands on the carrier and swings the free-wheel unit, then autonomously activates the driving unit without requiring manual switching or remote control. The system serves itself by using the angle-detecting unit to monitor user presence and swinging motion, and the micro processing unit to automatically start the motor, eliminating the need for separate power-on operations.
Solution Approach 2:
The patent replaces manual mechanical switching operations with an automated detection and control system. The angle-detecting unit uses sensors to detect the swinging motion of the free-wheel unit, and the micro processing unit processes this signal to activate the driving unit, substituting mechanical switch operations with electronic sensing and automated control.
2Ease of operation
If a swinging detection system is added to enable automatic power-on, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The free-wheel unit serves multiple functions: it is both a propulsion element and a control input device. The swinging motion of the free-wheel unit simultaneously provides propulsion and triggers the power-on sequence, eliminating the need for separate control mechanisms. The angle-detecting unit and micro processing unit form an integrated control system that handles both detection and activation functions.
Solution Approach 2:
The patent merges the power-on control function with the existing free-wheel unit structure. Instead of adding a separate switch or control panel, the system combines the power activation trigger with the natural swinging motion of the free-wheel unit, integrating multiple functions into a single operational mechanism.
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
This solution enhances user convenience by allowing power-on and power-control through simple swinging motions, improving the operational ease and control of electric vehicles, making them more user-friendly and accessible.
Implementation Method 1
The first angle-detecting unit is disposed at one of the free-wheel unit and the carrier, and is for detecting a swinging status between the free-wheel unit and the carrier so as to provide a swinging signal

AI summary
An electric vehicle includes a carrier, a free-wheel unit, a foot-wheel unit, a driving unit, a first angle-detecting unit and a micro processing unit. The carrier is for supporting a user. The free-wheel unit is disposed at one end of the carrier. The foot-wheel unit is disposed at the other end of the carrier. The driving unit is disposed at the free-wheel unit or the foot-wheel unit, and is for providing a power to the electric vehicle. The first angle-detecting unit is disposed at the free-wheel unit or the carrier, and is for detecting a swinging status between the free-wheel unit and the carrier so as to provide a swinging signal. The micro processing unit is signally connected to the driving unit and the first angle-detecting unit. When the swinging signal achieves a predetermined condition determined by the micro processing unit, the driving unit is turned on.
