Electric Vehicle Frame with Object Mounting Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electric-powered vehicle designs do not allow for the carriage of objects when used in a stand-up state, limiting its functionality as a cart.
Innovation Solution
The electric-powered vehicle is designed with a frame that includes an object mounting portion, a stay, and a handlebar, allowing it to be switched between ride, cart, Kickboard, and folding modes, enabling the user to either sit and ride or stand and carry objects, with the frame and stay angles adjusted to accommodate different uses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the foot rest portion is designed only for receiving feet, then the structure remains simple, but the vehicle cannot carry objects when used in stand-up state
Solution Approach 1:
The foot rest portion is designed with dual functionality: it serves both as a foot rest when the user is seated and as an object mounting platform when the user stands. This multi-functionality allows the same structural element to adapt to different usage scenarios without requiring separate components, thereby improving versatility while avoiding additional structural complexity.
2Ease of operation
If the handlebar is fixed in position, then the structure is simple, but the user cannot easily switch between sit-down and stand-up states
Solution Approach 1:
The handlebar is designed to be movable rather than fixed, allowing it to pivot between different positions. This dynamic configuration enables the handlebar to be adjusted to appropriate heights and angles for both sit-down and stand-up operating modes, facilitating easy mode switching while maintaining reasonable structural simplicity through the use of a pivot mechanism.
3Adaptability or versatility
If the seat is fixed in position, then the structure is simple, but the user cannot adjust the vehicle for different operating modes
Solution Approach 1:
The seat is designed with adjustability, allowing it to move between different positions and orientations. This dynamic seat configuration enables the user to adjust the seat to appropriate positions for both seated and standing operating modes, enhancing mode adaptability while maintaining structural simplicity through the use of an adjustment mechanism that does not require complex components.

AI summary
An electric-powered vehicle (10) includes a drive wheel (11), a coasting wheel (12), a frame (13), a stay (15), a seat (18), and a handlebar (17). The drive wheel (11) and the coasting wheel (12) are arranged to be spaced apart from each other in a traveling direction of the electric-powered vehicle (10). The frame (13) is arranged between the drive wheel (11) and the coasting wheel (12) and configured to rotationally support the drive wheel (11) and the coasting wheel (12). The frame (13) has an object mounting portion (13b). The stay (15) is coupled to the frame (13) and extends upward from the frame (13). The seat (18) and the handlebar (17) are supported by the stay (15). The electric-powered vehicle (10) has a plurality of modes including a ride mode, in which a user (U) uses the electric-powered vehicle (10) while being seated on the seat (18) and holding the handlebar (17), and a cart mode, in which the user (U) uses the electric-powered vehicle (10) while standing on the ground and holding the handlebar (17). The electric-powered vehicle (10) is configured to be selectively switched to a shape corresponding to each of the modes.
