Solution Overview

Problem

Existing electronic poker game machines require manual intervention to flip over incorrectly positioned playing cards, which compromises game fairness and increases operational costs due to the need for human supervision.

Innovation Solution

A flip-over mechanism with a flipping plate and tray that automatically flips playing cards by 180 degrees using a motor-driven turning disc and connecting rods to pivot the flipping plate and tray, ensuring cards are correctly oriented without manual operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual intervention is used to flip over incorrectly positioned playing cards, then the card orientation can be corrected, but game fairness is compromised and operational costs increase

Engineering Contradiction:

Improvecard orientation correctionVSAvoidgame fairness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system uses a camera to detect card orientation and automatically triggers the flipping mechanism to correct incorrectly positioned cards without human intervention, making the system self-correcting and maintaining game fairness

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical flipping with an automated mechanical flipping mechanism driven by a motor, which is controlled by optical detection (camera), substituting human operation with an automated electromechanical system

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If manual intervention is used to flip over playing cards, then card positioning can be corrected, but human resources are required increasing operational costs

Engineering Contradiction:

Improvecard positioning correctionVSAvoidoperational efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The system automatically detects and corrects card positioning errors through integrated camera detection and motor-driven flipping, eliminating the need for human operators to monitor and correct card positions continuously

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system maintains continuous automated monitoring and correction of card positions throughout the game, ensuring that card orientation issues are resolved immediately without interrupting game flow or requiring periodic human intervention

Inventive Principle:

Principle #20Continuity of useful action

3Extent of automation

If automated flipping mechanism is implemented, then manual operation is eliminated and game fairness is maintained, but device complexity increases

Engineering Contradiction:

Improvecard flipping automationVSAvoidmechanism structure

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The flipping mechanism is divided into independent functional modules: a motor for rotation, a flipping plate with pivot ears for movement, and a camera for detection, allowing each component to be optimized independently and simplifying maintenance

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of having the card move through a complex path, the patent inverts the approach by having the flipping plate rotate underneath the card to flip it, simplifying the mechanical path and reducing complexity

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A flip-over mechanism includes a frame, a flipping plate pivotally connected to the frame, and a tray. A first connecting rod and a second connecting rod are pivotally connected to the frame. The flipping plate is configured to receive a playing plate. A connecting lever, a first push handle and a second push handle are pivotally connected to the flipping plate. The other end of the connecting lever is pivotally connected to the tray. One side of the tray is pivotally connected to the flipping plate. The turning disc drives the connecting lever to push the flipping plate to turn upwards, the first push handle is driven by the first connecting rod to push the playing card, and the second push handle is driven by the second connecting rod to push the tray to turn upwards, such that the playing card is pushed into the tray.
