Shared Vehicle Return Verification via QR Code and NFC Spot Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing the return of shared vehicles, particularly in urban areas with high traffic and specific parking requirements, face challenges in accurately determining the parking status of shared vehicles using location tracking methods.
Innovation Solution
A system and method that utilizes QR codes or NFC tags for identifying parking spots, allowing users to initiate a return request through a mobile device, which is processed by a central server to verify the shared vehicle's parking status by receiving entry information from local devices associated with the parking lot, and transmitting a completion notification to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If location tracking method (GPS) is used to manage shared vehicle return, then the system can obtain vehicle location coordinates, but it cannot accurately determine whether the vehicle is parked in a legal parking spot or designated area
Solution Approach 1:
The patent introduces QR codes and NFC tags as intermediary elements placed at designated parking spots. These intermediaries contain encoded location information that enables precise verification of parking status without requiring complex GPS coordinate analysis. The mobile device scans or reads these intermediaries to confirm proper parking location.
Solution Approach 2:
The patent replaces the mechanical/GPS-based location tracking system with an optical/electromagnetic field-based identification system using QR code scanning or NFC communication. This substitution provides more accurate parking verification by directly identifying designated spots rather than calculating position from satellite signals.
2Reliability
If QR code or NFC tag identification method is used for parking spots, then the system can accurately verify parking status, but it requires additional infrastructure components at parking locations
Solution Approach 1:
The patent employs QR codes and NFC tags which are inexpensive, easily deployable identification elements. These can be printed or attached to parking spots without requiring complex installation infrastructure, making the system economically viable and easy to implement across multiple locations.
3Loss of information
If GPS location tracking is used, then the system can monitor vehicle position, but it cannot distinguish between legal and illegal parking areas in urban environments
Solution Approach 1:
The patent adds a new dimension of information verification by incorporating visual/optical identification (QR codes) or electromagnetic identification (NFC tags) at the parking spot level. This complements the GPS location data by providing discrete, verifiable identification of legal parking areas, transforming continuous location data into discrete verified status.

AI summary
A shared vehicle management system for managing a shared vehicle is described in the present disclosure. The shared vehicle management system includes a return request processing unit, a shared vehicle management unit and a parking determination unit. The return request processing unit is configured to receive, from a mobile device of a user, a shared vehicle return request including terminal identification information of the mobile device and parking spot identification information. The shared vehicle management unit is configured to identify the shared vehicle based on the terminal identification information of the mobile device. The parking determination unit is configured to determine, based on the parking spot identification information, that the shared vehicle identified by the shared vehicle management unit is parked on a parking spot corresponding to the parking spot identification information. The return request processing unit is further configured to transmit a notification of completion of return to the mobile device.
