Solution Overview

Problem

Conventional dice rolling methods allow players to physically handle dice, leading to potential advantages, delays, and disease transmission, necessitating a system that allows dice rolling without direct contact.

Innovation Solution

A dice rolling apparatus comprising a base, controller, sensor, motor, and dice enclosure, where a player's motion triggers the sensor to rotate the dice enclosure via a motor, enabling touchless rolling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If players physically handle dice to roll them, then the rolling action is simple and direct, but players can modify or swap dice to gain advantage

Engineering Contradiction:
Improveease of rolling diceVSAvoidfairness of dice rolling
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces an automated dice rolling machine as an intermediary device between the player and the dice. The player inputs a roll command, and the machine executes the rolling action through its internal mechanism, preventing players from directly handling or modifying the dice while maintaining fair and random rolling results.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the manual mechanical action of picking up and throwing dice with an automated mechanical system. The dice rolling machine uses controlled mechanical movements to tumble and roll the dice within an enclosed chamber, eliminating the need for players to physically manipulate the dice while preserving the randomness and fairness of the roll.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If players physically handle dice, then the rolling action is immediate, but players may lose dice or delay gameplay by rolling too far

Engineering Contradiction:
Improveease of rolling diceVSAvoidtime to retrieve dice
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The dice rolling machine serves as a stationary intermediary that contains the dice within its enclosed chamber. The dice never leave the controlled environment of the machine, eliminating the risk of losing dice and ensuring they are always readily available for the next roll without requiring players to search or retrieve them from distant locations.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent separates the dice storage and rolling function into a dedicated, stationary device. The dice remain confined within the machine's chamber throughout the game, while players interact only with the control interface. This segmentation ensures dice are always accessible and eliminates time loss associated with retrieving scattered or misplaced dice.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If players physically touch and share dice, then the social interaction is direct, but players may spread infectious diseases

Engineering Contradiction:
Improveease of rolling diceVSAvoiddisease transmission
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The dice rolling machine acts as a hygienic intermediary that completely eliminates direct physical contact between players and dice. Players interact with the machine through button presses or touchscreen interfaces, while the dice remain confined within the enclosed chamber. This mediation breaks the transmission chain for infectious diseases while preserving the core gaming function.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs an enclosed chamber with transparent or translucent walls that physically isolates the dice from players. This enclosure acts as a protective barrier that prevents pathogens from transferring between players and dice, maintaining hygiene while allowing players to observe the rolling process and verify fairness.

Inventive Principle:
Principle #30Flexible shells and thin films

4Object-affected harmful factors

If dice are kept in one place, then disease transmission is prevented, but players cannot physically roll the dice themselves

Engineering Contradiction:
Improvedisease transmission preventionVSAvoidplayer control in rolling
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent replaces the player's manual rolling action with an automated mechanical system controlled by the player through electronic or digital interfaces. The player maintains control and agency by selecting roll commands or inputting values, while the machine executes the physical rolling action, thus preventing disease transmission while preserving player engagement and control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The dice rolling machine is designed to be self-operating once activated by the player. The player initiates the roll through a simple input, and the machine autonomously executes the rolling sequence, manages the dice within its chamber, and displays the results. This self-service mechanism eliminates the need for players to physically handle dice while maintaining their role in the gaming process.

Inventive Principle:
Principle #25Self-service

AI summary

A dice rolling apparatus comprising a base, a controller, a sensor, a motor comprising a rotor, a dice enclosure comprising a member, a connecting structure. The member is attached to an inner surface of the shell of the dice enclosure and is positioned in a direction substantially parallel to an axis of rotation of the rotor. The connecting structure connects the rotor to the dice enclosure where the connecting structure extends from the rotor along the axis of rotation of the rotor. The sensor detects a motion proximate from the sensor and sends a triggering signal to the controller, and the controller sends a controlling signal to the motor when receiving the triggering signal from the sensor. The rotor and the dice enclosure rotates when the motor receives the controlling signal, and the dice placed inside the dice enclosure roll by making contact with the member.
