Rotary Card Shuffling Machine Anti-Cheating Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vertical 'prize wheel' type devices with fixed indicia are restricted by gaming laws, prone to rigging, and suffer from misbalance issues that allow cheaters to exploit biases, and fail to securely retain cards during rotation in a vertical orientation.
Innovation Solution
A rotary card shuffling machine with a wheel that supports cards in face-up positions around its circumference, using retention mechanisms like hook and loop strips or magnets to securely hold cards in place during rotation, allowing for easy removal and repositioning of cards between spins, ensuring random outcome generation and visibility of indicia to players.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed indicia are used on the wheel, then the wheel is simple to manufacture and operate, but it is restricted by gaming laws and prone to rigging
Solution Approach 1:
The patent applies the dynamics principle by making the indicia on the wheel changeable rather than fixed. The wheel can be dynamically reconfigured between different sets of indicia (e.g., numbers for roulette, letters for bingo, or other game-specific markers) through removable and repositionable components. This dynamic adaptability allows the same physical wheel to serve multiple games and jurisdictions while maintaining fairness, as the indicia can be randomly repositioned or completely changed between gaming sessions.
2Reliability
If variable indicia are used on the wheel, then gaming restrictions are avoided and rigging is prevented, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the wheel into modular components that can be independently assembled and reconfigured. The indicia are separated from the wheel structure itself, allowing them to be removed, replaced, or repositioned as needed. This segmentation enables the wheel to be configured for different games or jurisdictions without requiring complete replacement of the entire device, thus managing complexity while maintaining flexibility.
Solution Approach 2:
The patent implements universality by designing a wheel that can serve multiple functions across different games and jurisdictions. The same basic wheel structure can accommodate various indicia sets (numbers, letters, symbols) through removable components, making it applicable to roulette, bingo, and other games. This multi-functionality reduces the need for multiple specialized wheels while maintaining fairness and adaptability.
3Reliability
If cards are retained to the wheel during rotation, then cheating is impeded and game integrity is maintained, but the cards must be easily removable for rearrangement
Solution Approach 1:
The patent applies dynamics to the card retention mechanism by using features that provide secure holding during rotation but allow easy removal when needed. The cards are retained through mechanisms such as friction holds, magnetic attachments, or mechanical clips that can be easily released by the dealer. This dynamic retention ensures cards remain in place during the spin to prevent cheating, while still being accessible for rearrangement between games.
Solution Approach 2:
The patent uses an intermediary mechanism between the wheel and cards to facilitate both secure retention and easy removal. This intermediary could be a retention ring, magnetic strip, or clip system that mediates between the need for secure card holding during rotation and the need for quick card access for rearrangement. The intermediary feature provides just the right amount of holding force without requiring complex removal mechanisms.

AI summary
A rotary card shuffling and selection machine for use in playing a game of chance includes a wheel supported in a generally vertical plane for rotation about a horizontal rotary axis. The wheel is provided with a plurality of card positions arranged concentrically about the rotary axis. Each card position receives a card bearing indicia suitable to decide the game of chance. The cards are secured in card positions disposed around the wheel such they are oriented face up so that indica on the face of the card, which is relevant to the outcome of the game of chance, can be seen while the wheel is rotating.
