Card Shuffling Machine Turntable Detent Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The gaming industry seeks new and exciting methods to utilize playing cards as randomizing devices in games of chance, as traditional devices like dice and roulette wheels are subject to restrictive regulations, while playing cards offer less restrictive alternatives.
Innovation Solution
A card shuffling machine with a turntable that rotates freely and is slowed by a detent mechanism to randomly select one card from a set, allowing for unique and exciting game variations by using playing cards with indicia related to game decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If playing cards are used as randomizing devices, then regulatory restrictions are reduced, but device complexity and operational complexity increase compared to traditional dice or roulette wheels
Solution Approach 1:
The randomizing device is segmented into distinct functional modules: a rotatable platform with multiple card-receiving positions, a card dealing mechanism, and a card display system. Each module performs a specific function, making the overall complex system manageable and maintainable while achieving the goal of using playing cards as the randomizing element
Solution Approach 2:
The device is designed to be universally applicable to various card games and betting configurations. The rotatable platform can accommodate different numbers of card positions, and the system can be configured for different game types, reducing regulatory restrictions while managing complexity through standardized multi-functional design
2Reliability
If a turntable with multiple trays is used to hold cards, then card selection randomness is improved, but the device complexity and space requirements increase
Solution Approach 1:
Instead of spreading card trays horizontally in a single plane, the invention utilizes vertical stacking or multi-level arrangement of trays. This dimensional transition from 2D to 3D space allows multiple card positions to be accommodated in a compact footprint, maintaining random selection accuracy while reducing the horizontal space occupied by the turntable
3Measurement precision
If a detent mechanism is used to slow and stop the turntable, then card singulation precision is improved, but the device complexity increases
Solution Approach 1:
The mechanical detent mechanism is replaced or supplemented with electromagnetic or electronic braking and positioning systems. Sensors detect the turntable's rotational position and control the braking force electronically, achieving precise card position accuracy without the mechanical complexity of traditional detent mechanisms with multiple springs and levers
4Adaptability or versatility
If playing cards are used instead of dice or roulette wheels, then regulatory restrictions are reduced, but the ease of operation decreases due to card handling requirements
Solution Approach 1:
The card dealing mechanism is designed to automatically distribute cards to the appropriate positions on the rotatable platform without requiring manual card handling by operators. The system self-services by mechanically dealing, positioning, and presenting cards, thereby reducing regulatory restrictions while maintaining ease of operation through automation

AI summary
A card shuffling machine (10) includes a turntable (14) in which a plurality of cards (26) rest in respective trays (24). When the turntable (14) is spun, a tongue-like detent (30) resiliently strikes a circular arrangement of peg-like dividers (28) which progressively slows the turntable (14) to a stopped condition. A pointing device singulates one of the cards (26) which can be lifted from its tray (24) and the indicia thereon announced as a game decision. The indicia on the singulated card (26) can be scanned with a machine-readable code and processed through a digital processor (38) to resolve a variety of games played through respective computerized consoles (44).
