Substitute Gaming Chip Management System with RFID Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing management systems for game houses struggle to accurately manage and monitor the liquidation of substitute gaming chips, particularly due to issues with reading devices under the game table, sensitivity problems, blind areas in imaging, and advanced fraudulent methods.
Innovation Solution
A management system that includes individually identifiable substitute gaming chips, a game table, a win/loss determining device, a substitute gaming chip tray, a dealer chip determining device, a measuring device, and a management control device. The management control device compares the collection and payment amounts of substitute gaming chips with the increase and decrease amounts in the tray, using information from multiple devices to ensure accurate accounting and detect fraud.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RFID tags are attached to substitute gaming chips to grasp the number and total amount, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The system divides the chip management function into separate modules: RFID reading devices positioned at specific locations (dealer side, player side, tray) to independently count chips in different areas. This segmentation allows accurate chip tracking without requiring a single complex system, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The patent introduces a management control device as an intermediary that collects data from multiple RFID reading devices and performing counters, then calculates the balance. This intermediary coordinates multiple simple reading devices to achieve accurate chip management without requiring each individual device to be complex.
2Difficulty of detecting and measuring
If image analysis is used to monitor chip movement and detect fraud, then the detection capability is improved, but the measurement precision deteriorates due to blind areas and sensitivity issues
Solution Approach 1:
The patent replaces optical image analysis with RFID electromagnetic field-based detection to count chips. RFID reading devices emit electromagnetic fields that interact with RFID tags on chips, providing precise detection without suffering from optical blind areas or sensitivity problems that plague image-based systems.
Solution Approach 2:
RFID tags serve as intermediaries between the chips and the reading devices. These tags carry identification information that enables precise detection and counting, eliminating the need for direct optical observation and its associated measurement precision problems.
3Reliability
If multiple devices are used to grasp chip positions and amounts, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The patent combines the functions of multiple devices (RFID reading devices, performing counters, management control device) into a coordinated system where each device performs a specific function and their outputs are integrated. This merging approach improves reliability through redundancy while managing complexity through functional specialization and integration.
Solution Approach 2:
The system implements feedback mechanisms where the management control device continuously monitors data from RFID reading devices and performing counters, compares actual chip amounts with expected amounts, and detects discrepancies. This feedback loop ensures reliability by enabling real-time verification and fraud detection while coordinating multiple devices efficiently.

AI summary
A management system includes a card distributing device that determines a win/loss result of a game using substitute gaming chips on a game table, a dealer chip determining device that specifies type and the number of substitute gaming chips held in a substitute gaming chip tray, a measuring device that measures position, type, and the number of substitute gaming chips on the game table, and a management control device that has a function of transmitting a signal or performing display on a display device depending on a comparison result between a collection amount and an increase amount and a comparison result between a payment amount and a decrease amount, and changes the signal or an output content of the display depending on a content of inconsistency when the inconsistency is determined in the comparison results.
