Standing Vehicle Front Wheel Embedded Platform Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric motor-driven standing vehicles have a high risk of tipping over due to their high center of gravity, especially when navigating obstacles, tight curves, and inclined surfaces, which increases the risk of accidents in environments like factory halls and airports.
Innovation Solution
The design features a steerable front wheel embedded within the standing platform, laterally offset rear wheels forming an isosceles triangle, and support elements that prevent the front wheel from being affected by impacts, ensuring continuous ground contact and enhanced stability through a pivoting handlebar system and integrated support wheels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the standing platform is arranged flat and close to the ground, then the vehicle structure is simple and easy to manufacture, but the center of gravity becomes high and the risk of tipping over increases
Solution Approach 1:
The patent introduces support wheels that contact the ground laterally, adding a new dimensional element to the vehicle's ground interaction. This lateral support dimension compensates for the high center of gravity caused by the flat standing platform, resolving the contradiction between structural simplicity and tipping risk.
2Area of stationary object
If a two-wheel configuration is used, then the footprint is reduced and the vehicle is compact, but the risk of tipping over increases when navigating obstacles and tight curves
Solution Approach 1:
The patent segments the wheel configuration into three wheels (two rear drive wheels and one front steerable wheel) plus lateral support wheels. This segmentation provides multiple contact points with the ground, improving stability during obstacle navigation and tight curve traversal while maintaining a compact footprint.
3Ease of operation
If a three-wheeled arrangement with steerable front wheels is used, then maneuverability is improved, but susceptibility to tipping increases on tight curves and inclined surfaces
Solution Approach 1:
The patent uses lateral support wheels positioned on the vehicle's wide sides to provide counterbalancing support during cornering and incline traversal. These support wheels act as a mechanical counterweight system that offsets the tipping forces generated during high-maneuverability operations.
4Ease of operation
If the standing platform is made larger to provide more standing area, then user comfort is improved, but the vehicle's overall dimensions and space requirement increase
Solution Approach 1:
The patent utilizes the lateral dimension by positioning support wheels on the wide sides of the vehicle body. This allows the standing platform to be extended in the lateral direction to provide more standing area, while the support wheels prevent tipping and maintain operational stability without significantly increasing the vehicle's length or width.

AI summary
The invention relates to an electric-motor-driven standing vehicle (2) for personal transport, having an electric drive motor (28) and a standing platform (4), with a front wheel (20) situated along a centre axis (M) of the standing platform (4), with a handlebar stem (22) coupled thereto, with handlebars (24) for pivoting the front wheel (20) about a rotation axis (D) formed by the handlebar stem (22), and with two rear wheels (40) which are spaced from the front wheel (20) and are each laterally offset relative to the centre axis (M). In the standing platform (4) there is a through-opening (18), which is preferably completely closed around the circumference thereof and through which the handlebar stem (22) passes or in which the front wheel (20) sits. The front wheel (20) is flanked on both sides in each case by at least one supporting element (42) which protrudes from a lower face (8) of the standing platform (4), facing the ground (10).
