Gaming Currency EM-RFID Separation for Stable Casino Gate Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing casino gaming currencies face issues with unstable RFID reading due to interference between EM and RFID signals, leading to inaccurate detection and potential illicit activities, especially when managing the movement of gaming currencies across casino boundaries.
Innovation Solution
A management system incorporating an EM wire member and an RFID part, where the EM wire member and RFID part are arranged apart in the thickness direction of the gaming currency, allowing for non-contact detection and reading of gaming currencies using an EM detecting system and RFID reading system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an EM coil and RFID antenna are built in the gaming currency, then electromagnetic signal detection and RFID reading are enabled, but signal interference occurs between the EM and RFID components
Solution Approach 1:
The patent applies dimensionality change by arranging the EM wire member and RFID antenna in different spatial dimensions. Specifically, the EM wire member is positioned in the radial direction while the RFID antenna is positioned in the thickness direction of the gaming currency. This multi-dimensional arrangement allows both components to coexist without signal interference, enabling stable RFID reading while maintaining EM detection capability.
2Power
If the EM coil size is increased to match or exceed the antenna size, then EM signal strength is improved, but the device complexity and manufacturing constraints increase
Solution Approach 1:
The patent applies local quality by optimizing the size and position of the EM wire member relative to the RFID antenna. The EM wire member is configured with a diameter that is 0.5 to 2 times the diameter of the RFID antenna, and is positioned at a specific distance (0.5 to 2 times the antenna diameter) from the antenna center. This localized optimization ensures sufficient EM signal strength without requiring the entire device to be enlarged, thus reducing overall complexity.
3Volume of moving object
If the RFID part and EM wire member are placed close together, then the gaming currency size is reduced, but signal interference between the two components occurs
Solution Approach 1:
The patent resolves the space-conflict problem by utilizing different spatial dimensions for the EM wire member and RFID antenna. The EM wire member is arranged radially while the RFID antenna is arranged in the thickness direction, allowing both components to be compact yet spatially separated enough to avoid interference. This dimensional arrangement maintains small gaming currency size while ensuring reliable detection.
