Solution Overview

Problem

Existing live-dealer online gambling systems are limited by the number of players that can participate at a gaming table, typically allowing only a maximum of seven players.

Innovation Solution

A mechanism is introduced for automatically removing playing cards from a gaming table using a door that opens downward when a card is placed on it, accompanied by a hardware processor for detection and control, and a container for capturing the card, which can be moved to the dealer, along with a graphics version of the card presented on the player's display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional gaming table is used with manual card handling, then the dealer can manage cards manually, but the number of players is limited to a maximum of seven

Engineering Contradiction:
Improvenumber of playersVSAvoidcard removal mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the card removal function from manual dealer action and implements it through an automated door mechanism. The door is positioned to allow cards to be placed on it and then automatically removed by opening downward, separating the card removal task from the dealer's manual operations and enabling scalable player participation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The door mechanism is designed to automatically open downward when a card is placed on it, using the card's own weight and position to trigger the removal action. This self-service mechanism reduces the need for manual intervention and allows the system to handle card removal autonomously, supporting increased player capacity.

Inventive Principle:
Principle #25Self-service

2Productivity

If manual card handling is used, then the system is simple to operate, but the game scalability is limited

Engineering Contradiction:
Improvegame scalabilityVSAvoidautomated door control
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent replaces manual mechanical card handling with an automated door mechanism controlled by a hardware processor. The processor detects when a card is placed on the door and automatically triggers the door to open downward, substituting human judgment and action with automated sensing and actuation, thereby enabling game scalability while maintaining operational simplicity.

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

Solution Approach 2:

The system incorporates a sensor that detects when a playing card is placed on the door, providing feedback to the hardware processor. This feedback loop enables the processor to automatically control the door opening action, ensuring that card removal is precisely timed and executed without manual intervention, thus enhancing game scalability.

Inventive Principle:
Principle #23Feedback

3Area of stationary object

If cards remain on the table surface, then all players can see the cards, but the table space is occupied limiting player capacity

Engineering Contradiction:
Improvetable spaceVSAvoidcard visibility
Core Design Contradiction:
Area of stationary objectVSLoss of information

Solution Approach 1:

The patent moves the card removal action from the horizontal table surface to a vertical dimension by having the door open downward. Cards are placed on the door at table level for visibility, then removed vertically below the table surface, freeing up horizontal table space while maintaining card visibility during the dealing process.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The door mechanism is integrated into the table structure, with the door and container for received cards positioned below the table surface. This nesting approach allows the card removal and storage system to be contained within the table's existing structure, preserving table space while enabling automated card handling.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

Mechanism (which can include system, methods, and media) for removing a card from a gaming table are provided, the mechanisms comprising: detecting when a playing card is placed on a door on a table surface of a gaming table; and causing the door to automatically open downward when the playing card is detected as being placed on the door so that the playing card slides downward to a space below the table surface. In some embodiments, these mechanisms further comprise controlling the opening of the door using a hardware processor, and optionally using stepper motor to control the opening of the door. In some embodiments, these mechanisms further comprise generating a graphics version of the playing card; and presenting the graphics version of the playing card on a player's computer display after the playing card has slid below the table surface.
