Solution Overview
Problem
Inverted pendulum type vehicles face challenges in compacting electrical components such as control units, gyro sensors, and transformers while ensuring effective cooling and protection, which affects their design and functionality for both outdoor and indoor use.
Innovation Solution
The electrical control unit is strategically disposed between the main wheel and the driving unit, with a vertical orientation and a fan for efficient cooling, and the gyro sensor is positioned rearwardly to optimize space utilization and protection, allowing for a compact and efficient design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electrical components are disposed in a concentrated manner (unitized), then the amount of wiring required for the harness is reduced and assembly is facilitated, but the size of one unit increases and the degree of freedom in the attachment position to the vehicle body drops
Solution Approach 1:
The electrical control unit is divided into multiple independent components: controller (301), transformer (304), gyro sensor (308), and fan (321). Each component is separately mounted on the vehicle body frame at optimized positions rather than being consolidated into a single unitized assembly, thereby maintaining attachment position freedom while simplifying individual component assembly.
2Reliability
If the electrical control unit includes a gyro sensor, then it is necessary to dispose the electrical control unit at a position above and in the proximity of the main wheel, but this constraint limits the effective disposition of other electrical components
Solution Approach 1:
The electrical components are arranged in the vertical dimension above the main wheel rather than being constrained to a horizontal plane. The controller (301), transformer (304), and gyro sensor (308) are stacked vertically, with the fan (321) positioned below to provide cooling. This vertical arrangement allows all components to be disposed in proximity to the main wheel while maintaining adequate space for each component and its functions.
3Volume of moving object
If the vehicle is designed for both outdoor and indoor use, then high compaction is demanded, but effective cooling and protection of electrical components become more difficult
Solution Approach 1:
A fan (321) is introduced as an active cooling intermediary device positioned below the electrical components. The fan forces air flow through the ventilation passages formed by the vehicle body frame structure, providing effective cooling for the controller (301), transformer (304), and gyro sensor (308). This active cooling system enables compact component arrangement while maintaining adequate thermal management for both outdoor and indoor operation.
