Hand-Forming Card Shuffler With Gripper-Based High-Speed Dealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 'hand-forming' shufflers require serial completion of shuffling and disgorgement cycles, are limited by pusher mechanism cycle times, and suffer from elongated purging cycles and vulnerability to jamming due to narrow slots, leading to reduced responsiveness and increased downtime.
Innovation Solution
A card handling device that eliminates the need for pusher mechanisms and reduces shuttling excursions by using a gripper mechanism to create a wedge-shaped opening for card insertion, ensuring rapid card distribution and verification, and isolating faulty decks to prevent downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pusher mechanisms are used to extract cards from compartments, then cards can be distributed to the discharge portal, but the pusher mechanism cycle times limit the shuffler speed and increase downtime
Solution Approach 1:
The patent removes the pusher mechanism entirely from the system. Instead of using a pusher to extract cards from compartments, the design allows cards to be directly accessed and removed from the compartments by the discharge mechanism, eliminating the time-consuming pusher cycle and its associated downtime.
Solution Approach 2:
Rather than pushing cards out from the compartments using a pusher mechanism, the invention inverts the approach by allowing cards to be pulled or accessed directly from the compartments in a more efficient manner, reversing the traditional push-out methodology to achieve faster card extraction.
2Manufacturing precision
If narrow slots are used in compartments for card insertion, then card organization is improved, but the shuffler becomes vulnerable to jamming
Solution Approach 1:
The patent modifies the dimensional parameters of the compartment slots, making them wider and more tolerant. This parameter change maintains adequate card organization while significantly reducing the vulnerability to jamming caused by narrow slots, thereby improving reliability without sacrificing precision.
3Ease of operation
If serial completion of shuffling and disgorgement cycles is required, then card distribution is controlled, but responsiveness is reduced and downtime increases
Solution Approach 1:
The patent enables overlapping or concurrent execution of shuffling and disgorgement cycles. While one cycle is in progress, another can begin, creating continuous useful action rather than waiting for serial completion. This maintains controlled card distribution while significantly reducing overall cycle time and improving responsiveness.
4Reliability
If elongated purging cycles are used to clear faulty decks, then verification is thorough, but shuffler downtime increases
Solution Approach 1:
The patent implements preliminary verification checks that identify faulty decks early in the process. By detecting and isolating faulty decks before they complete the full shuffling cycle, the system performs thorough verification while minimizing the time the shuffler is taken offline for purging, thus maintaining high productivity.

AI summary
The invention herein describes a card handling apparatus used for automatically creating play-ready hands for use in casino poker games whereupon the apparatus may be programmed to accommodate a number of different game variations, and a variable number of players. The apparatus verifies the integrity of each deck before discharging the play-ready hands to a first discharge portal. Decks that do not meet verification criteria are isolated and moved to a second discharge portal. Non-faulty decks are moved to a metering station where they are metered to a card output tray at high speed while forming the play-ready substacks. Two decks may be shuffled, verified and queued within the device before commencing a game, or a second deck may undergo shuffling while play-ready hands from a first deck are being metered to the output tray.
