Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If UWB and BLE wireless communication are used for fare payment, then communication range is extended beyond short distance, but electromagnetic wave interference occurs between ranging and data communication
Solution Approach 1:
The patent implements periodic time-division multiplexing where UWB ranging communication and UWB data communication are performed in alternating time slots. The mobile terminal and base station sequentially switch between ranging mode and data communication mode, preventing electromagnetic interference while maintaining extended communication range benefits.
Solution Approach 2:
The communication process is segmented into distinct phases: beacon detection phase using BLE, ranging phase using UWB, and data communication phase using UWB. Each phase operates independently with dedicated time resources, allowing the system to achieve wide area coverage while avoiding interference through temporal separation of functions.
2Quantity of substance
If multiple mobile terminals are simultaneously connected, then service capacity increases, but connection management and ticket gate specification become complex
Solution Approach 1:
The system employs feedback mechanisms where the base station receives ranging results from multiple mobile terminals, identifies which terminal has entered the payment area based on distance measurements, and selectively establishes data communication connections. This feedback-driven approach enables automatic ticket gate specification and simplifies connection management despite multiple simultaneous connections.
Solution Approach 2:
The patent introduces a base station as an intermediary that manages connections between multiple mobile terminals and the fare payment system. The base station acts as a mediator that receives beacon signals, performs ranging processing, determines payment area entry, and controls data communication, thereby simplifying the complexity of direct terminal-to-gate connections.
3Area of stationary object
If beacon detection is performed before ranging, then terminal detection range is extended, but processing time increases
Solution Approach 1:
The system performs preliminary beacon detection using BLE technology before initiating UWB ranging communication. This preliminary action allows the system to pre-identify potential mobile terminals in the extended detection range, so that when a terminal enters the payment area, ranging and subsequent data communication can begin immediately without delay.
Solution Approach 2:
The patent implements a dynamic two-stage detection approach where the system transitions from wide-area BLE beacon detection to precise UWB ranging only when necessary. This dynamic adaptation allows the system to maintain extended detection coverage while minimizing processing time by activating the more time-consuming UWB ranging only for terminals that have been preliminarily identified as potential payment candidates.

Data Source
AI summary
There is provided an information processing device, a mobile terminal, and an information processing method capable of executing information processing more reliably. Bluetooth Low Energy (BLE) is used to transmit a beacon that is a signal for detecting a mobile terminal within a communication range of the BLE. Ultra Wide Band (UWB) is used to perform ranging processing of measuring at least a distance from the mobile terminal detected using the beacon to a UWB gate unit provided with a fare calculation zone in which fare payment processing is performed with the mobile terminal. Then, when it is detected that the mobile terminal enters the fare calculation zone on the basis of a result of the ranging processing using UWB, data communication for payment using UWB is performed between the UWB gate unit and the mobile terminal. The present technology can be applied to, for example, a touchless fare payment system using BLE and UWB.
