Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In dice games, especially Sic Bo, accurately reading the number of dots on dice thrown becomes difficult as the game size increases, and physically rolling dice in gaming machines can lead to deterioration and damage due to the motion of moving parts, affecting gameplay and player motivation.

Innovation Solution

A detection device with wireless tags on dice and a reader system featuring multiple antenna portions disposed to form overlapping detection areas, allowing accurate dot counting regardless of dice location and preventing damage from moving parts, using electromagnetic induction for communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple antenna portions are disposed to form overlapping detection areas, then detection accuracy is improved, but device complexity increases

Engineering Contradiction:

Improvedetection accuracyVSAvoiddevice complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The detection system is segmented into multiple antenna portions (first antenna portion and second antenna portion) that are disposed at different locations. Each antenna portion independently detects wireless tag information, and the results are integrated to achieve comprehensive detection coverage and improved accuracy.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple antenna portions are combined to form overlapping detection areas. The first antenna portion and second antenna portion work together, with their detection areas overlapping to ensure that dice at any position on the playing board can be reliably detected, improving overall detection accuracy.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If the field is moved to enable dice rolling, then gameplay realism is improved, but damage to connecting members increases

Engineering Contradiction:

Improvegameplay realismVSAvoiddamage to connecting members

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The mechanical connection between the field and detection device main body is replaced with wireless communication. The antenna portions on the moving field communicate wirelessly with the reader in the detection device main body, eliminating physical connecting members that would be damaged by motion.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

Wireless electromagnetic signals serve as an intermediary between the moving field and the stationary detection device main body. This intermediary communication method allows data transfer without direct physical connection, preventing damage to connecting members during field movement.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If dice are actually thrown, then game authenticity is improved, but reading accuracy deteriorates

Engineering Contradiction:

Improvegame authenticityVSAvoidreading accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

Instead of directly reading physical dot patterns on moving dice, wireless tag information is used as a digital copy or representation of the dice state. The wireless tags store and transmit dice information without requiring direct visual or physical contact with the moving dice, maintaining reading accuracy despite dice motion.

Inventive Principle:

Principle #26Copying

AI summary

A detection device is used in a gaming machine that detects numbers of dots on a plurality of dice having wireless tags. The detection device reads the wireless tags which are embedded on each face of the dice by a reader having an antenna. The antenna of the reader includes a first antenna portion disposed substantially in a central portion of a field that supports the dice, and formed in a substantially circular shape, and a plurality of second antenna portions disposed so as to superimpose a detection area of the first antenna portion, and having a detection area larger than the first antenna portion. The first antenna portion and the plurality of the second antenna portions are disposed so as to have a portion of detection areas mutually superimposed on a playing board.
