Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric vehicles face challenges such as large turning radius, weight issues making them difficult to carry on public transportation, and limited remote control functionality, which hinders their flexibility and convenience for short or medium distance transportation.
Innovation Solution
The design includes a modular electric vehicle system with a main body that can be divided into a front and rear section, allowing independent movement of the front section, equipped with electric wheels and a controller that receives input from users or remote controllers, enabling improved agility and expanded functionality through wireless communication and sensor integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electric vehicle uses a fixed main body structure, then the vehicle structure is simple, but the turning radius is large and flexibility is reduced
Solution Approach 1:
The main body is divided into a front main body and a rear main body that can be removably connected. The front main body includes a front wheel assembly and the rear main body includes a rear wheel assembly, allowing the vehicle to be segmented into independent units that can operate separately or together, enabling tight turning when separated and stable transport when connected.
Solution Approach 2:
The connection between the front and rear main bodies is made dynamic through a removable connection mechanism, allowing the vehicle structure to change from a fixed two-wheeled configuration to a separable one-wheeled configuration, providing adaptability for different operating conditions such as tight turns versus stable transport.
2Reliability
If the electric vehicle uses a heavy main body structure, then the vehicle stability is improved, but the portability and ease of carrying is reduced
Solution Approach 1:
The vehicle is segmented into a front main body with a first wheel assembly and a rear main body with a second wheel assembly, both connected removably. This segmentation allows the user to carry only the necessary portion (front or rear main body) depending on the task, significantly improving portability while maintaining stability when the complete vehicle is assembled and in use.
3Adaptability or versatility
If the electric vehicle has integrated remote control functions, then the functionality is expanded, but the device complexity and cost is increased
Solution Approach 1:
The controller is designed with multi-functionality, serving both as the primary control system for direct user input and as a remote control receiver for wireless commands. This universal design allows the same hardware to fulfill multiple functions without requiring separate dedicated systems, thereby expanding functionality while controlling complexity and cost.
4Adaptability or versatility
If the electric vehicle uses a removable connection between front and rear main bodies, then the flexibility and adaptability is improved, but the structural complexity is increased
Solution Approach 1:
The vehicle structure is segmented into a front main body and a rear main body connected through a removable connection mechanism. This segmentation enables the vehicle to be configured in multiple ways (connected for stable transport, separated for tight turns or carrying), providing high adaptability while keeping the connection mechanism relatively simple through standardized interfaces.

AI summary
Electric vehicles, electric vehicle systems, and methods for controlling the electric vehicles or electric vehicle systems are described. In one implementation, an electric vehicle includes a main body for carrying a user, a plurality of electric wheels mounted on the main body, and a controller mounted on the main body. The main body includes a front main body and a rear main body removably connected to the front main body. The front main body can move independently when disconnected from the rear main body. In some embodiments, at least one of the plurality of electric wheels is mounted on the front main body. The controller is configured to send drive signals to the plurality of electric wheels according to input of the user. The plurality of electric wheels are configured to rotate according to the drive signals. The electric vehicles and the electric vehicle systems described in the present disclosure have a separable main body, advantageously allowing for short or medium distance transportation at low cost, flexibility in turning, and great potential for expanding their functionality.
