Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If physical dice are used in electronic wagering games, then game authenticity and visual appeal are improved, but game integrity and result reliability deteriorate

Engineering Contradiction:

Improvegame authenticityVSAvoidgame integrity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces an electronic die as an intermediary object that combines physical appearance with electronic control. The electronic die resembles a physical die but contains electronic components (sensor, communication interface) that enable reliable result transmission to the gaming device, thus maintaining both authenticity and integrity

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical dice reading methods (manual observation) with electronic detection systems. Sensors detect the visible face of the electronic die and automatically transmit results via communication interfaces, eliminating human error and tampering risks while preserving the visual appeal of physical dice

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If sensors and communication interfaces are added to detect and transmit die results, then result reliability is improved, but device complexity increases

Engineering Contradiction:

Improvedie result accuracyVSAvoidelectronic component count

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The electronic die integrates multiple functions into a single compact device: it displays die faces visually, contains sensors to detect the visible face, and includes communication interfaces to transmit results. This multi-functionality reduces the need for separate components and simplifies the overall system architecture

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the die display, sensing, and communication functions into the electronic die itself rather than requiring separate external components. The sensor and communication interface are integrated within the die housing, creating a unified device that reduces system complexity

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An electronic dice shaker device includes a housing defining an interior cavity, the housing including a transparent window between the interior cavity and an exterior of the housing. The electronic dice shaker device further includes a sensor that detects, in response to an electronic die coming to rest in the interior cavity, a visible face of the electronic die. The electronic dice shaker device further includes a first communication interface that, in response to detection of the visible face of the electronic die, provides an indication of the visible face of the electronic die to a gaming device.
