Parking Fee Notification Timing for Reduced Communication Costs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of parking lots face challenges in accessing timely information about the usage status of parking lots.
Innovation Solution
A parking information service system that includes a receiving unit for parking start time information, a calculation unit for determining parking fees, and a transmitting unit for displaying these fees on a user's terminal at a designated timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If parking fee information is provided continuously to users, then users can access timely information about parking lot usage status, but communication costs increase and users may be disturbed during parking
Solution Approach 1:
The system provides parking fee information to users at periodic intervals rather than continuously. The notification unit transmits fee information at predetermined timings (e.g., when parking duration reaches certain thresholds or at regular intervals), reducing communication frequency while ensuring users receive timely updates about their parking status and costs.
2Loss of information
If parking fee information is provided continuously to users, then users can access timely information about parking lot usage status, but user disturbance increases
Solution Approach 1:
The notification unit provides information at predetermined intervals rather than continuously, reducing user disturbance while maintaining timely information delivery. The system sends notifications at appropriate moments based on parking duration thresholds or scheduled intervals, avoiding constant interruptions to users.
3Measurement precision
If real-time parking fee calculation is implemented, then accurate fee information is provided, but system complexity increases
Solution Approach 1:
The parking management system automatically performs fee calculations based on recorded parking start and end times without requiring manual intervention. The calculation unit computes fees using predetermined rate structures, and the notification unit automatically transmits results to users, eliminating the need for complex manual processing while maintaining accuracy.

AI summary
[Problems to be Solved] To provide a user of a parking lot with information about a usage status of the parking lot at an appropriate timing. [Solution] A parking information service system includes: a receiving unit receiving information about a parking start time of a vehicle in a predetermined area; a calculation unit calculating a parking fee of the vehicle; and a transmitting unit transmitting information about the parking fee to a terminal of a user of the vehicle, in which the information about the parking fee is displayed (S132) on a display unit of the terminal at a first timing (S131).
