Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single reading device (antenna) is used to detect gaming chips, then the device complexity is reduced, but the reliability of chip tracking deteriorates due to signal blocking conditions
Solution Approach 1:
The patent combines multiple reading devices (first reading device and second reading device) into a unified gaming machine system. This merging allows the system to detect gaming chips through multiple antennas simultaneously, ensuring that at least one device can detect the chip even when signal blocking occurs, thereby resolving the contradiction between device complexity and tracking reliability.
Solution Approach 2:
The patent introduces spatial diversity by placing reading devices at different positions and orientations on the gaming board. By detecting chips from multiple spatial dimensions rather than a single point, the system overcomes signal blocking issues and maintains reliable tracking without requiring excessive complexity in any single detection point.
2Measurement precision
If multiple acquiring devices are used to detect gaming chips, then the measurement precision of chip detection is improved, but the device complexity increases
Solution Approach 1:
The patent designs reading devices that perform multiple functions: they not only detect the presence of gaming chips but also read identification information from transponders embedded in the chips. This multi-functionality allows the system to achieve high measurement precision without proportionally increasing device complexity, as the same hardware serves multiple detection purposes.
Solution Approach 2:
The gaming board is divided into multiple detection zones with separate reading devices positioned at different locations. Each reading device independently monitors its zone, and the system integrates data from all zones to achieve comprehensive and precise chip detection across the entire board, balancing precision requirements with manageable device complexity.

AI summary
Gaming chips 30 have an IC tag 34 which is embedded therein, and a special bar code 101 invisible to the naked eye, which is printed thereon. A server calculates the number of gaming chips 30 based on individual information of the IC tag 34 that was read out by a reader 38, based on individual information of the special bar codes 101 read out by a bar code scanner 102, based on weight data acquired at a weighing device 40 and based on image data processed in a camera 103. Further, the server checks a partial number or the total number of gaming chips 30 thus calculated, and outputs the check results from a display or speaker.
