Self-Balancing Power System with Segmented Drum Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-torque control technology for two-wheeled vehicles is complex, with many internal parts that can compromise balance and suffer from inadequate heat dissipation due to the arrangement of motors and controllers in the same internal space.
Innovation Solution
A self-balancing power system is introduced, featuring separate drum units for power motors, a power output set, and an anti-torque power set, which are arranged outside the drum units to improve stability and heat dissipation, and reduce space occupancy and energy consumption.

Engineering Contradiction Analysis
1Volume of moving object
If motors and controllers are arranged in the same internal space, then space occupancy is reduced, but heat dissipation effect deteriorates
Solution Approach 1:
The power system is divided into separate functional modules: power motors are arranged in drum units while controllers are positioned in separate spaces. This segmentation allows each component to have dedicated space for optimal performance, with controllers having sufficient space for heat dissipation while power motors remain compact within drum units.
Solution Approach 2:
The system transitions from a two-dimensional planar arrangement to a three-dimensional spatial distribution. Power motors are placed inside drum units at different locations, while controllers are positioned in separate spatial zones, utilizing vertical and lateral spacing to achieve both compact overall volume and adequate heat dissipation pathways.
2Force
If anti-torque control system has many internal parts, then anti-torque capability is improved, but device complexity increases
Solution Approach 1:
The power output function and anti-torque function are merged into a unified power system architecture. The same power motors and transmission components serve dual purposes: providing propulsion power and generating anti-torque for balance control, thereby achieving both functions without proportionally increasing system complexity.
Solution Approach 2:
The drum units and power motors are designed with multi-functionality, serving both as power transmission components and as anti-torque generation elements. This universal design allows the system to achieve sophisticated anti-torque control capability while maintaining a relatively simple overall structure through shared components.
