Vehicle Proximity Notification System for Crowded Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle locating systems, such as those using GPS data, are insufficient in accuracy, making it difficult for users to find a target vehicle, especially in crowded environments.
Innovation Solution
A leading system that includes an output unit to send a predetermined signal to an area around a vehicle, with a terminal carried by a person receiving this signal and automatically providing notifications to help the person locate the vehicle, using proximity alerts and communication units to refine the positioning and prevent erroneous notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS data is used for vehicle location notification, then the system can provide basic positioning functionality, but the accuracy is insufficient to help users find vehicles in crowded environments
Solution Approach 1:
The notification system is segmented into multiple levels: first notification when entering a first area (larger range), and second notification when entering a second area (narrower range). This segmentation allows the system to provide graduated guidance, improving accuracy progressively as the user approaches the vehicle.
Solution Approach 2:
The system transitions from two-dimensional GPS coordinates to three-dimensional spatial notification by defining concentric areas (first area and second area) around the vehicle. This adds a spatial dimension to the notification system, enabling more precise location guidance through area-based proximity detection.
2Quantity of substance
If multiple vehicles are parked closely together, then parking density increases, but it becomes difficult for users to identify and find their target vehicle
Solution Approach 1:
The system provides localized notifications specific to each user's target vehicle. When a user enters the notification area, the terminal device sends a targeted notification specifically for their vehicle, allowing them to identify their vehicle among many others through precise local guidance rather than searching through the entire parking area.
Solution Approach 2:
The terminal device acts as an intermediary between the vehicle and the user. It receives notification information from the notification device and relays it to the user's mobile terminal, providing a communication bridge that enables accurate vehicle identification even in crowded parking environments.
3Area of stationary object
If notification signals are sent to a wide area around the vehicle, then users can receive notifications from farther away, but erroneous notifications may occur from signals of other vehicles
Solution Approach 1:
The system performs preliminary identification by comparing the notification signal with predetermined information about the user's target vehicle before triggering a notification. This preliminary verification step ensures that only authentic notifications for the user's specific vehicle are activated, preventing erroneous notifications from other vehicles while maintaining wide coverage.
Solution Approach 2:
The terminal device provides feedback by comparing the received notification signal with stored predetermined information. This feedback mechanism verifies whether the signal corresponds to the user's target vehicle, enabling the system to distinguish between valid and invalid notifications even when multiple vehicles are broadcasting signals in the same area.

AI summary
A leading system has an output unit configured to output a predetermined signal to a first area around a vehicle, and a terminal carried by a person. The terminal has a receiving unit configured to receive the predetermined signal when the person enters the first area and a first notification unit configured to automatically perform a first notification to the person when the predetermined signal is received by the receiving unit.
