Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current parking management systems lack efficient proximity sensing and real-time inventory management for vehicles near access gates, leading to inaccuracies and delays in tracking vehicle presence and transactions.
Innovation Solution
The system employs Bluetooth Low-Energy (BLE) proximity sensing with SmartBeacon devices and integrated vision systems to identify vehicles with unique beacon IDs, enabling accurate detection within one vehicle length of access gates and real-time monitoring of vehicle ingress and egress, using a combination of BLE, LTE, and vision-based technologies for communication and data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional parking management systems are used, then system simplicity is maintained, but measurement precision and detection accuracy of vehicle presence deteriorate
Solution Approach 1:
The patent combines multiple detection technologies (BLE proximity sensing, vision-based systems, and beacon ID recognition) into a unified parking management system. This integration enables accurate vehicle presence detection within one vehicle length of access gates while maintaining system coordination through a centralized backend server that manages data from all sensing components.
Solution Approach 2:
The system employs multi-functional detection capabilities that can identify both vehicle presence and inventory status using the same infrastructure. The BLE sensors and vision systems serve dual purposes: detecting vehicle proximity and monitoring parking space occupancy, thereby improving measurement precision without proportionally increasing device complexity.
2Productivity
If real-time inventory management is implemented, then productivity and transaction efficiency are improved, but loss of time for data processing and communication increases
Solution Approach 1:
The system performs preliminary detection and recording of vehicle ingress and egress events as they occur, maintaining a continuous live inventory database. By pre-processing and storing vehicle presence data in real-time rather than batch-processing later, the system enables rapid transaction authorization without time loss during actual parking operations.
Solution Approach 2:
The backend server continuously receives feedback from BLE sensors and vision systems regarding vehicle presence and updates the inventory database in real-time. This feedback loop enables immediate detection of parking events and instant communication of inventory status, thereby improving transaction efficiency without significant time loss through automated real-time data synchronization.
3Measurement precision
If BLE proximity sensing is used to detect vehicles near access gates, then measurement precision is improved, but reliability of detection may deteriorate due to signal interference
Solution Approach 1:
The patent combines BLE proximity sensing with vision-based detection systems to create a redundant detection mechanism. When BLE signal reliability is compromised by interference, the vision system provides alternative verification of vehicle presence, thereby maintaining detection consistency while preserving the high measurement precision of BLE when conditions permit.
