Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional fare validation systems using smartcards or NFC are used, then ticket validation can be performed, but in crowded conditions multiple mobile devices can lead to incorrect ticket detection and reduced accuracy
Solution Approach 1:
The system divides the ticket validation process into distinct phases: approach detection via Bluetooth beacons, validation zone entry detection via cameras, and ticket verification. This segmentation allows the system to process passengers sequentially through defined zones rather than attempting simultaneous validation of multiple devices, thereby improving accuracy while maintaining throughput.
Solution Approach 2:
The patent introduces Bluetooth beacons as intermediary devices that establish a preliminary connection with mobile devices before the passenger reaches the fare gate. This intermediary step allows the system to pre-identify and pre-validate tickets, reducing the complexity of simultaneous validations at the gate and improving both accuracy and throughput.
2Reliability
If passengers must manually present physical tickets or smartcards for validation, then ticket verification can be performed, but passenger throughput is reduced due to manual actions required
Solution Approach 1:
The system performs preliminary ticket validation actions before the passenger reaches the fare gate. Bluetooth beacons detect the mobile device and initiate validation sequences in advance, and cameras capture images of passengers before they reach the validation point. This preliminary action eliminates the need for manual ticket presentation at the gate, reducing processing time while maintaining reliability.
Solution Approach 2:
The mobile device automatically performs validation functions without requiring manual user actions. The device continuously broadcasts its ticket information via Bluetooth, and the system automatically detects and validates the ticket when the passenger enters the validation zone, eliminating the need for passengers to manually present tickets or smartcards.
3Ease of operation
If Bluetooth beacons are used to detect passenger proximity, then hands-free validation is enabled, but system complexity increases due to additional components
Solution Approach 1:
The patent integrates Bluetooth beacons with existing mobile devices that passengers already carry, rather than requiring separate ticketing devices. The mobile device serves multiple functions: it acts as both the ticket storage medium and the Bluetooth communication device. This multi-functionality reduces the need for additional dedicated components while enabling hands-free operation.
Solution Approach 2:
Bluetooth beacons serve as simple intermediary devices that only need to broadcast validation zone information and receive mobile device responses. They do not require complex processing capabilities, keeping the beacon hardware simple while enabling hands-free validation through the intermediary communication layer between beacons, cameras, and ticketing systems.
