Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to develop a sub-mobility device charging system that allows vehicles to efficiently charge sub-mobility devices while in motion, ensuring the sub-mobility devices have sufficient power for passengers without compromising the vehicle's ability to reach its destination, as existing systems face limitations in electric power supply due to the sub-mobility devices' high power requirements.
Innovation Solution
The system includes an acquisition unit for inputting travel schedules, a main electric power supply unit, and a controller that manages electric power distribution to sub-mobility devices, using both internal and external charging methods to prioritize vehicle movement while ensuring sub-mobility devices are charged based on their destination requirements, utilizing a main electric power supply system integrated with the vehicle and external power transmission coils for efficient power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the vehicle supplies electric power to the sub-mobility device during transit, then the sub-mobility device achieves sufficient charge for its destination, but the vehicle's battery may deplete before reaching its destination
Solution Approach 1:
The system performs preliminary charging of the sub-mobility device by supplying electric power from the vehicle's battery during transit, ensuring the device is adequately charged before the passenger disembarks at the destination
Solution Approach 2:
The charging control unit monitors the charge levels of both the vehicle's battery and the sub-mobility device, dynamically adjusting the power supply to ensure the vehicle maintains sufficient power to reach its destination while adequately charging the sub-mobility device
2Reliability
If the vehicle waits to charge the sub-mobility device at the destination, then the vehicle's battery is preserved, but the sub-mobility device may not have sufficient power for the passenger's needs
Solution Approach 1:
The system performs preliminary charging during the vehicle's transit to the destination, eliminating the need to wait until arrival to charge the sub-mobility device
Solution Approach 2:
The charging process occurs continuously during the vehicle's transit, maximizing the utilization of available time and ensuring the sub-mobility device is charged without interrupting the vehicle's journey

AI summary
A sub-mobility device charging system for a vehicle is capable of moving while carrying a sub-mobility device in which a passenger sits. The system includes an acquisition unit, a main electric power supply unit and a controller. The acquisition unit acquires a destination or traveling schedule inputted to the sub-mobility device; the main electric power supply unit supplies electric power to the sub-mobility device carried in the vehicle; and the controller controls to supply electric power to the sub-mobility device via the main electric power supply unit. The controller charges the sub-mobility device on a basis of the acquired traveling schedule for the sub-mobility device in the destination, and generates a traveling route to guide the charged sub-mobility device to a stop-off points corresponding to the destination.
