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

VSEngineering 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

Engineering Contradiction:
Improveability to carry objectsVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improveease of mode switchingVSAvoidhandlebar mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improvemode adaptabilityVSAvoidseat adjustment mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #15Dynamics

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.
