Parking Notification System Using Actual Travel Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for notifying users about parking time limits at parking lots do not accurately account for actual travel times and environmental conditions, leading to inaccurate remaining stay time calculations and insufficient prior notifications.
Innovation Solution
An information notification system that uses a navigation system and a mobile device to measure actual travel times, store historical data for accurate round trip calculations, and provide prior notifications based on environmental conditions and parking lot attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system uses fixed or estimated travel time values for notification calculations, then the notification system is simple to operate, but the accuracy of remaining stay time calculation deteriorates
Solution Approach 1:
The patent replaces manual time estimation with automatic GPS-based travel time measurement. The mobile device automatically acquires position information at parking lot and destination, calculates actual travel time, and uses this data for accurate remaining stay time notification, eliminating the need for users to manually estimate travel duration.
Solution Approach 2:
The system performs self-service by automatically measuring travel time and calculating notification timing without requiring user input. The mobile device autonomously acquires position data, computes travel duration, determines remaining stay time, and triggers notifications at the appropriate moment, making the system both easy to operate and highly accurate.
2Measurement precision
If the system provides notification at the exact moment when remaining time reaches zero, then the notification timing is precise, but the user does not have sufficient time to prepare for departure
Solution Approach 1:
The patent implements preliminary action by calculating and providing notification before the remaining stay time reaches zero. The system determines the optimal notification timing based on actual measured travel time, ensuring users receive advance warning with sufficient time to prepare for departure while maintaining precise timing based on real data.
Solution Approach 2:
The system uses feedback from actual travel time measurement to adjust notification timing. By continuously monitoring position information and calculating real travel duration between parking lot and destination, the system provides dynamically adjusted notification timing that accounts for actual conditions rather than using fixed estimates.
3Device complexity
If the system does not account for environmental conditions and historical data, then the system complexity is low, but the accuracy of travel time estimation deteriorates
Solution Approach 1:
The patent applies preliminary action by storing historical travel time data and environmental condition information in advance. The mobile device accumulates position information, travel times, and environmental data from previous trips, then uses this pre-collected data to improve the accuracy of travel time estimation for future notifications.
Solution Approach 2:
The system implements feedback by using historical travel time data and environmental conditions to continuously improve estimation accuracy. The mobile device compares actual measured travel times with estimated values, adjusts calculations based on environmental factors like weather and time of day, and refines future predictions based on accumulated experience.

AI summary
An information notification method includes obtaining a parking time limit during which a user is allowed to continuously park a vehicle at a parking lot, measuring a travel time required for the user to move from the parking lot to a destination, obtaining a round trip time required for the user to make a round trip between the destination and the parking lot, calculating a remaining time during which the user is allowed to stay at the destination by subtracting, from the parking time limit, the round trip time and an elapsed time measured from when the user has reached the destination, determining whether the remaining time is less than or equal to a threshold value preset to zero or greater, and notifying the user that the remaining time is short if it is determined that the remaining time is less than or equal to the threshold value.
