Motorized Platform Hub Assemblies for Rider Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional self-balancing motorized vehicles with two wheels face stability issues due to rider overcompensation, leading to loss of control and increased power consumption, and the addition of a third wheel can interfere with obstacles and hills.
Innovation Solution
A motorized platform with independent drive assemblies, including a mount bracket body connected to a platform, drive hub assemblies with motors, and a suspension system, equipped with sensors to detect motion and improve stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If self-balancing mechanisms are used to maintain rider attitude, then the rider can maintain proper riding position, but the rider may over compensate their leaning control attitude which can result in loss of control and increased power consumption
Solution Approach 1:
The patent employs sensors (accelerometers, gyroscopes, load cells) to continuously monitor platform tilt and rider position, providing real-time feedback to the control system. This feedback mechanism allows the system to make precise, minimal adjustments rather than continuous counteracting movements, reducing energy consumption while maintaining stability and control.
Solution Approach 2:
The self-balancing mechanism automatically adjusts platform orientation based on sensor input without requiring active rider intervention. The system serves itself by detecting tilt and autonomously correcting position, reducing the rider's control burden while minimizing energy-wasting overcompensation.
2Reliability
If a third wheel is added to increase stability, then accidents can be minimized, but it causes interference with moving over tall obstacles and up steep hills
Solution Approach 1:
The patent divides the stabilization function across multiple independent two-wheel platforms connected by articulation joints, rather than using a single three-wheel configuration. This segmentation allows each platform to independently adapt to terrain while maintaining overall system stability through coordinated control.
Solution Approach 2:
The patent uses dynamically adjustable articulation joints that allow the platforms to change their relative positions and orientations in response to terrain variations. This dynamic configuration enables the system to maintain stability on varied terrain without the geometric constraints of a fixed three-wheel design.

AI summary
Motorized hub assemblies for use with platforms and the corresponding motorized platforms are presented. At least one of the hub assemblies can be a motor and can contain an internal motor to propel the platform when activated. In some embodiments, the motorized platform has two sets of motorized wheels or two sets or motorized treads for differential rate maneuvering. In some embodiments, different base platforms are mounted to a single set of wheels or a single tread to provide a sporty style ride. A handlebar can also be implemented for greater stability. In all cases, there is no requirement for an electronic stabilization platform.
