Poker Hand Carousel Shuffler With Fast Purge and Dual-Tray Dealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 'hand-forming' shufflers require multiple compartments for statistical randomization, leading to larger device size and longer purging times, which affect responsiveness and efficiency.
Innovation Solution
The apparatus utilizes centrifugal force to retain and align card substacks in radially-arranged nests, eliminating the need for clamping devices and motorized pusher mechanisms, allowing direct movement from the input to the output without temporary storage, and uses a microcontroller for randomization and simultaneous discharge to two output trays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple compartments are used for statistical randomization, then randomization quality is improved, but device size and purging time increase
Solution Approach 1:
The patent merges the randomization and storage functions into a single carousel structure where cards are randomly distributed among multiple slots that serve both as randomization elements and as temporary holding positions. This eliminates the need for separate compartments while maintaining statistical randomization quality through the random slot assignment mechanism.
Solution Approach 2:
The carousel slots serve multiple functions: they act as randomization elements during the shuffling process, as temporary storage during card accumulation, and as discharge positions during purging. This multi-functionality reduces the overall number of components needed while achieving the same technical effects.
2Productivity
If multiple compartments are used for card storage, then card distribution capability is improved, but purging time increases
Solution Approach 1:
The carousel enables continuous operation by allowing card distribution and purging to occur in an uninterrupted rotational sequence. The random slot assignment ensures that cards can be continuously accumulated and discharged without requiring sequential access to multiple separate compartments, thereby reducing purging time while maintaining distribution capability.
Solution Approach 2:
The patent employs a dynamic carousel that rotates to different positions for card input, randomization, and discharge operations. This dynamic repositioning allows the system to efficiently manage card flow and purging operations without the mechanical complexity of multiple fixed compartments, reducing purging time while maintaining card distribution capability.
3Reliability
If clamping devices and motorized pusher mechanisms are used, then card retention and movement control are improved, but device complexity and cost increase
Solution Approach 1:
The carousel structure utilizes gravity and centrifugal force during rotation to naturally retain and discharge cards without requiring external clamping devices or motorized pushers. The rotational motion itself provides the necessary control for card movement, eliminating complex mechanical retention mechanisms while maintaining reliable card handling.
Solution Approach 2:
The patent replaces complex mechanical retention systems (clamps and pushers) with a simpler rotational mechanism that uses centrifugal force and gravity to control card movement. This substitution reduces device complexity and cost while maintaining effective card retention and discharge control through the controlled rotation of the carousel.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances responsiveness and cost efficiency by reducing the number of compartments needed, enabling faster card distribution and purging, while supporting various game variations.
Implementation Method 1
The radial receiver is utilized in the apparatus to rotate about a rotational axis and possess a plurality of nests which are radially-arranged about the rotational axis. The movable retainers retain the card substacks within the nests as the radial receiver rotates about the rotational axis.

AI summary
A card handling apparatus creates pre-formed hands for use in poker games and may be programmed to accommodate a number of different game variations and players. An unshuffled card input portal and a shuffled card discharge portal each have two output trays, each discharging play-ready hands. Two play-ready hands are simultaneously discharged face down to each of the output trays at the initiation of a game. A first player can choose to receive his/her hand from either tray, where each vacant tray is immediately replenished such that the next player has a choice of receiving their hand from either tray. In one embodiment the apparatus randomly assigns one of the trays as the source for each player's hand, in another embodiment the cards are discharged to the output trays in a face-up orientation. The apparatus also has a rapid purge mode which quickly clears residual cards.
