Innovation Solution
A card reading device with a card shoe part, detachable cover, card reading part, control part, display part, and wireless output part that can be integrated and powered by a detachable battery, eliminating the need for communication and power supply cables by using wireless communication to transmit data to an external device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication cable and power supply cable are connected to the card reading device, then the device can transmit data and receive power, but the device becomes difficult to move and maintain
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. The card reading device communicates game outcome data to the external device via wireless transmission, eliminating the need for physical communication cables. This substitution resolves the contradiction by maintaining reliable data transmission while completely removing the mobility restriction caused by cables.
Solution Approach 2:
The patent integrates both power supply and data transmission functions into a single wireless communication interface. The wireless module handles both communicating game outcomes and receiving power commands, reducing the need for separate cable connections and improving device portability while maintaining all essential functions.
2Loss of information
If communication cable is connected to transmit game outcome data, then data can be displayed on external device, but the cable becomes a hindrance to moving the device
Solution Approach 1:
The patent replaces the mechanical cable-based data transmission system with a wireless communication system. The card reading device transmits game outcome information wirelessly to the external display device, eliminating the physical cable that restricts device movement. This allows the device to be freely repositioned on the game table while maintaining continuous data transmission capability.
3Duration of action of stationary object
If power supply cable is connected to supply electric power, then the device can operate continuously, but the cable causes malfunctions and complicates maintenance
Solution Approach 1:
The patent replaces the physical power supply cable connection with a wireless power transmission system. Power is transmitted wirelessly to the card reading device, eliminating the cable that causes malfunctions and complicates maintenance. This wireless power supply maintains continuous operation capability while significantly reducing maintenance complexity and malfunction risks associated with physical cable connections.
4Adaptability or versatility
If cables are connected for data transmission and power supply, then the device functions are complete, but the cables hinder participatory game operations
Solution Approach 1:
The patent replaces the cable-based connection system with wireless communication, enabling the card reading device to be freely moved to different positions on the game table for participatory games. The wireless system maintains complete device functionality for data transmission and power supply while allowing flexible repositioning between dealer and player positions without cable constraints.

Data Source
AI summary
A card reading device includes a card shoe part in which cards are housed, a card reading part that reads information on the cards drawn out, a control part that determines the outcome of a game based on the read information on the cards, and display parts that display the determined outcome of the game. In a tabletop game system, the information on the cards read by the card reading part and information on the game outcome determined by the control part are transmitted from the card reading device to a main computer apparatus via wireless communication. The card reading device includes a battery that supplies electric power to the control part, the display parts and a wireless output part. The card reading device, as such, is capable of facilitating moving the card reading device in a participatory tabletop game.
