Vehicle Management System Dynamic Return Space Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle sharing systems do not effectively manage parking space occupation times, leading to increased usage duration as they do not account for the parking space where the vehicle is left after use.
Innovation Solution
The system sets returnable spaces among parking spaces, designating a vacant parking space as a returnable space when the reserved vehicle is started, allowing it to be used by another vehicle, thereby reducing occupation time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the vehicle sharing system only determines return based on GPS positional information matching predetermined return spaces, then the system is simple to operate, but the parking space occupation time increases because the system does not account for the parking space where the vehicle is left after use
Solution Approach 1:
The system performs preliminary actions by designating the current parking space as a returnable space before the vehicle actually returns. When a vehicle is rented out, the system proactively sets the space where the vehicle is currently parked as an available return space for other vehicles, rather than waiting until the vehicle actually returns to update the space availability. This preliminary update of space status reduces occupation time without requiring complex real-time tracking changes.
2Productivity
If the system designates returnable spaces dynamically when vehicles are rented out, then parking space utilization efficiency improves, but the system complexity increases due to additional space management operations
Solution Approach 1:
The system applies universality by making parking spaces multi-functional. Each parking space can serve as both a current parking location for rented vehicles and simultaneously as a returnable space for other vehicles. The space designation is not fixed but can dynamically change roles, allowing the same physical space to fulfill multiple functions in the vehicle sharing system, thereby improving utilization without requiring additional dedicated spaces.
Solution Approach 2:
The system performs preliminary designation of returnable spaces when a vehicle is rented out, rather than waiting until the vehicle actually returns. This proactive update of space status allows other vehicles to be directed to these spaces in advance, improving overall space utilization efficiency without requiring complex real-time coordination during the actual return process.

AI summary
A vehicle management system for managing vehicles used by users has a usage managing unit configured to accept a user's reservation for use of one of the vehicles, set returnable spaces among parking spaces to be managed, the returnable space being the parking space to which a reserved vehicle can be returned after using the reserved vehicle, and set a planned return space to be a destination for the reserved vehicle among the returnable spaces, and a usage determining unit configured to determine whether or not the use of the reserved vehicle is started. The usage managing unit is configured to set a vacant parking space to the returnable space when the usage determining unit determines that the use of the reserved vehicle is started. The vacant parking space is the parking space in which the reserved vehicle is parked at the time of departure.
