Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking systems face challenges in managing parking fees accurately without recognizing vehicle numbers, especially in lots without entrance or exit barriers, leading to difficulties in handling underpaid or unpaid parking and inability to extend parking times.
Innovation Solution
A system utilizing AI-based image analysis from sensors to track vehicle exits and calculate parking fees based on real-time monitoring, enabling automatic payment processing without vehicle number recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If vehicle number recognition is used for parking management, then payment accuracy is improved, but system complexity increases due to requiring barriers and recognition equipment
Solution Approach 1:
The patent extracts the vehicle number recognition function from the essential requirements, creating a parking management system that works without barriers, recognition equipment, or vehicle number capture. The system uses only sensor-based presence detection to trigger payment, removing complex recognition subsystems while maintaining payment accuracy through alternative detection methods.
Solution Approach 2:
The system enables automatic payment processing based on sensor-detected vehicle presence and exit timing, without requiring manual intervention, barrier operations, or recognition system activation. The payment process is self-triggered by the sensor detecting vehicle movement, eliminating the need for operator involvement or complex recognition-based authorization.
2Productivity
If prepayment is required for parking, then payment processing is simplified, but user convenience deteriorates due to inability to charge only for actual parking time
Solution Approach 1:
The system performs preliminary registration of payment information when the vehicle enters the parking area, but does not charge immediately. The actual payment is calculated and processed based on the real exit time detected by sensors, allowing pre-registration without prepayment. This enables efficient payment processing while ensuring users only pay for actual parking duration.
Solution Approach 2:
The system continuously monitors vehicle presence using sensors and provides feedback on actual parking duration. When the vehicle exits, the system calculates the precise parking time based on sensor data and triggers payment accordingly. This feedback mechanism ensures payment accuracy matches actual usage while maintaining efficient automated processing.
3Device complexity
If manual parking time recording is used, then system complexity is reduced, but measurement precision of parking duration deteriorates
Solution Approach 1:
The patent replaces manual recording mechanisms with automated sensor-based detection systems. Sensors continuously monitor vehicle presence and automatically detect exit events, eliminating the need for manual time recording while achieving precise measurement of parking duration. The system substitutes human-operated mechanical recording with electronic sensing and automated calculation.

AI summary
A method of providing a parking service comprises calculating overlap degree of a target vehicle and specific parking area by analyzing a parking monitoring image obtained from a sensor for monitoring specific parking area at a first time of point and determining through the calculated overlap degree whether the target vehicle is parked; recording the target vehicle in an exit queue when the target vehicle goes out of the specific parking area by analyzing a parking monitoring image obtained from the sensor at a second time of point; performing an exit process when the target vehicle included in the exit queue moves to go out of the specific parking area by analyzing a parking monitoring image obtained from the sensor at a third time of point. A payment process in accordance with an exit of the target vehicle is performed based on payment information preregistered when the target vehicle is parked.
