Game Chip Reflection Member for Stacked RFID Signal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional game chips stacked for betting are difficult to read accurately due to scattered electromagnetic waves, leading to unstable recognition and erroneous data reading, especially when using high-frequency wireless communication.
Innovation Solution
The game chip incorporates a reflection means, such as a cylindrical metallic foil or plate, to reflect electromagnetic waves emitted by a reader/writer, ensuring the signal is directed upward and not lost externally, allowing for correct data reading even when chips are stacked.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If game chips are stacked high to accommodate large bets within the assigned area, then the bet amount capacity is improved, but the electromagnetic wave signal strength deteriorates due to scattering and attenuation
Solution Approach 1:
The patent converts the harmful scattering and attenuation of electromagnetic waves into a beneficial concentrated signal path by introducing a reflective member. The reflective member redirects scattered electromagnetic waves back toward the game chip stack, transforming the harmful signal loss into enhanced signal strength and enabling reliable reading of stacked chips
2Speed
If high-frequency wireless communication is used for data reading, then the communication speed is improved, but the signal scattering and interference worsen
Solution Approach 1:
The reflective member captures and redirects the scattered high-frequency electromagnetic waves, converting the harmful scattering effect into a beneficial concentrated signal path that maintains communication speed while reducing interference and signal loss
3Area of stationary object
If game chips are stacked vertically, then the area utilization is improved, but the adjacent chips interfere with each other through scattered electromagnetic waves
Solution Approach 1:
The reflective member redirects scattered electromagnetic waves from adjacent chips back toward their respective stacks, converting the harmful interference into a beneficial signal reinforcement that enables reliable reading of vertically stacked chips in compact betting areas

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables reliable and stable data reading of stacked game chips by maintaining the electromagnetic wave's strength and preventing interference between adjacent chips, allowing for accurate processing of bets in gaming machines.
Implementation Method 1
antenna means (for example, an antenna (electrode, etc.)) connected to the circuit means and configured such that a resonant state can be entered with an antenna of the read device through a electromagnetic wave
Implementation Method 2
reflection means (for example, a reflector, a reflection member, etc.) for reflecting the electromagnetic wave emitted by the antenna of the read device toward the upper surface of the stacked game chips

AI summary
The present invention relates to the technology of recognizing and reading each game chip although game chips are stacked. The present invention is a game chip storing data readable by a reader/writer having an antenna which emits an electromagnetic wave and available in a stack of game chips, and includes: an IC device for communicating data at a request from the reader/writer; an antenna electrode connected to the IC device, and configured such that the antenna electrode can enter a resonant state with an antenna of the reader/writer through an electromagnetic wave; and a reflection member for reflecting an electromagnetic wave reflected from the antenna of the reader/writer toward upper game chips in the stack.
