Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Eco-friendly vehicles face inconvenience due to the need for charging, which restricts their immediate use, as they cannot travel during battery charging and require developed infrastructure, leading to delayed arrival times and inefficiencies.
Innovation Solution
A vehicle system that enables charging through regenerative braking and communication with other vehicles for battery charging, allowing for priority modes and torque adjustments based on road slope and state of charge, facilitating charging during travel and reducing infrastructure dependency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If eco-friendly vehicles charge the battery at a charging station, then the battery charge level is improved, but the vehicle cannot travel during charging and arrival time is delayed
Solution Approach 1:
The patent applies preliminary action by enabling the vehicle to charge the battery in advance during towing operations. When a vehicle is being towed, the motor functions as a generator to generate electricity that charges the battery before the vehicle needs to travel independently, thus eliminating the need for separate charging station stops and reducing arrival time delays
Solution Approach 2:
The patent converts the harmful effect of towing (which normally implies vehicle incapacitation) into a beneficial charging opportunity. During towing operations, the vehicle's motor generates electrical energy through regenerative braking or drag-based generation, transforming what would be pure energy loss into useful battery charging capacity
2Productivity
If eco-friendly vehicles use regenerative braking to charge the battery, then charging efficiency is improved, but the vehicle requires developed charging infrastructure and cannot operate independently
Solution Approach 1:
The patent applies self-service by enabling the vehicle to charge its own battery using its own motor during towing operations. The vehicle independently generates and stores electrical energy through regenerative braking mechanisms without requiring external charging infrastructure, making the system self-sufficient and adaptable to various operational environments
Solution Approach 2:
The patent applies universality by making the motor serve multiple functions: it acts as both a propulsion device during normal operation and as a generator during towing operations to charge the battery. This multi-functionality eliminates the need for dedicated charging infrastructure and allows the vehicle to adapt to different operational modes using the same hardware components

AI summary
A vehicle is provided that includes a battery; a motor configured to rotate a wheel using electric power charged in the battery; and a communication device that performs communication with other vehicles and a terminal. A controller operates the communication device to transmit request information of a charging service when an amount of charge of the battery is equal to or less than a preset amount of charge and charges the battery based on electric power generated by the motor while using the charging service through one of the other vehicles.
