Solution Overview
Problem
RFID-enabled gaming table systems face interference issues between RFID and LED components due to close proximity, leading to potential inaccuracies in data transmission and disruptions in signal reliability, affecting both financial transactions and player experience.
Innovation Solution
Implementing a gaming table system design that coordinates the timing of RFID antenna polling and LED circuit activity to minimize interference, using a node controller as an intermediary to manage LED updates independently of the main controller, and employing a two-circuit-board solution with a substrate made of aluminum to reduce magnetic field interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If RFID and LED components are placed in close proximity on the gaming table, then the table can provide integrated data capture and visual feedback functions, but interference between the components causes signal reliability issues and data transmission inaccuracies
Solution Approach 1:
The patent divides the table system into separate circuit boards - one dedicated to RFID components and another to LED components. This physical segmentation isolates the electromagnetic environments of each component type, preventing interference while maintaining integrated functionality through coordinated control by the table controller.
Solution Approach 2:
The patent introduces a substrate as an intermediary element between the RFID and LED circuit boards. This substrate acts as a mediator that provides electrical isolation and mechanical support, allowing both components to coexist in close proximity without direct electromagnetic interference between them.

If RFID and LED components operate simultaneously in close proximity, then the system can provide real-time game information display, but magnetic field interference disrupts signal reliability
Solution Approach 1:
The patent introduces a substrate as an intermediary element between the RFID and LED circuit boards. This substrate acts as a mediator that provides electrical isolation and mechanical support, allowing both components to coexist in close proximity without direct electromagnetic interference between them.
Solution Approach 2:
The patent applies different material properties to different regions of the table system - specifically using conductive materials in certain areas and non-conductive materials in others. This local differentiation of material properties helps manage electromagnetic fields and minimize interference between RFID and LED components while maintaining their respective functions.
