Solution Overview
Problem
Current vehicle identification systems in parking structures face challenges due to outdated or poorly crafted parking rules, leading to inefficiencies in managing parking availability and economics, particularly in dense areas where technology can assist in improving the parking experience.
Innovation Solution
A system utilizing cameras and detectors to capture images and scan for wireless device identifiers, processing these to extract license plate identifiers and associate them with wireless device identifiers, allowing for the use of wireless device identifiers as alternatives to license plate identifiers for vehicle identification, and storing records in an electronic storage system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If license plate identifiers are used for vehicle identification, then vehicle tracking is possible, but identification accuracy decreases when license plate extraction is difficult
Solution Approach 1:
The patent introduces wireless device identifiers (Bluetooth MAC addresses, Wi-Fi identifiers) as intermediary elements to bridge the gap between vehicle physical presence and identification. When license plate extraction fails or is difficult, the system uses these wireless identifiers as alternative mediators to achieve reliable vehicle identification, thus resolving the contradiction between maintaining identification accuracy and ensuring reliability in difficult extraction conditions
Solution Approach 2:
The system changes the identification parameter from visual license plate characters to wireless device electromagnetic identifiers. By transitioning from optical recognition (license plate extraction) to wireless signal detection (Bluetooth/Wi-Fi identifiers), the system maintains identification capability even when visual conditions are poor, thereby improving both accuracy and reliability in difficult extraction scenarios
2Productivity
If only license plate extraction is used for vehicle identification, then system complexity is low, but identification efficiency decreases when plates are obscured
Solution Approach 1:
The patent makes the vehicle identification system multi-functional by enabling it to operate through multiple identification methods: primary license plate extraction and alternative wireless device identifier detection. This universality allows the system to maintain high identification efficiency and success rate regardless of whether license plates are visible or obscured, as the wireless detection method serves as a universal fallback mechanism
3Reliability
If wireless device identifiers are used as alternative to license plate identifiers, then vehicle identification reliability improves, but device complexity increases
Solution Approach 1:
The system implements self-service by automatically detecting and associating wireless device identifiers with vehicles without requiring manual intervention. The automatic association mechanism and fallback logic operate autonomously, managing the increased complexity through self-configuration and self-management, thereby achieving improved reliability while minimizing the operational burden of the enhanced system complexity
