Card Shooter Device With Entry/Exit Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional card shoe apparatuses are vulnerable to fraudulent acts such as the insertion of false cards and inappropriate dealing of cards during card games.
Innovation Solution
A card shoe apparatus equipped with a card housing unit, a card reading unit, a control unit, a display unit, and a card entry/exit restriction unit that includes functions to prohibit fraudulent insertion and inappropriate dealing by using UV sensors and electromagnetic solenoids to control card movement based on game rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional card shoe apparatus with CCD image sensor and optical system is used, then card reading function is achieved, but the apparatus is vulnerable to fraudulent insertion of false cards from the exit
Solution Approach 1:
The patent applies preliminary anti-action by implementing a card entry/exit restriction unit that proactively prevents fraudulent card insertion before it can compromise the system. The restriction unit includes sensors and actuators that detect attempted card insertions from the exit and actively block them, countering the harmful effect before it affects card reading reliability
Solution Approach 2:
The patent segments the card shoe apparatus into distinct functional units: a card housing unit, a card reading unit, and a card entry/exit restriction unit. This segmentation allows the restriction unit to independently address security vulnerabilities without interfering with the card reading function, resolving the contradiction between reliability and security
2Ease of operation
If manual card taking out from card housing unit is allowed, then card dealing operation is enabled, but inappropriate dealing and fraudulent acts can occur
Solution Approach 1:
The patent implements feedback control through the card entry/exit restriction unit, which monitors card movements and provides real-time feedback to the control unit. The system tracks when cards are removed from the housing unit and verifies that dealing operations comply with game rules, preventing inappropriate dealing while maintaining manual operation capability
Solution Approach 2:
The card entry/exit restriction unit serves as an intermediary between the manual card dealing operation and the card housing unit. It mediates by allowing legitimate card removals for dealing while blocking fraudulent attempts, enabling ease of operation without compromising security
3Object-affected harmful factors
If card entry/exit restriction unit is added to prevent fraud, then security is improved, but device complexity increases
Solution Approach 1:
The patent merges the card entry/exit restriction unit with the existing card shoe apparatus structure. The restriction unit integrates sensors, actuators, and control logic into the housing unit and opening unit, which are existing components. This merging approach enhances fraud prevention capability while minimizing the increase in overall device complexity

AI summary
A card shoe apparatus including a card housing unit for housing a plurality of cards; an opening in the card housing unit for manually withdrawing the cards one by one from the card housing unit in a card reading direction; a card reading unit that reads information on the cards as the cards are manually withdrawn from the card housing unit in the card reading direction; a control unit that stores rules of a card game and determines the results of the card game based on the information read by the card reading unit and the rules of the card game; an optical device that detects movements of the cards relative to the card reading direction; and a card entry/exit restriction unit provided in the opening. The card entry/exit restriction unit restricts the entry or exit of any of the cards when the cards are improperly withdrawn from the opening.
