Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If traditional lighting and visual guide systems are used in live dealer games, then the system structure remains simple, but clear visual cues for card placement and dealer illumination are insufficient

Engineering Contradiction:
Improvevisual cue clarityVSAvoidlighting system complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The lighting system is segmented into multiple independent light sources including LED strips along the rail, individual lights above card positions, and lights near the dealer position. Each segment can be independently controlled to provide specific visual cues for card placement, betting areas, and dealer illumination, thereby achieving clear visual guidance without requiring a monolithic complex system

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the gaming table are provided with differentiated lighting characteristics. LED strips along the rail provide continuous illumination, individual lights above card positions provide focused guidance for card placement, and additional lights illuminate the dealer position. This localized quality enhancement ensures each area receives appropriate illumination intensity and distribution for its specific function

Inventive Principle:
Principle #3Local quality

2Measurement precision

If multiple light sources and camera systems are integrated, then accurate card placement guidance is achieved, but the device complexity increases

Engineering Contradiction:
Improvecard placement accuracyVSAvoidsystem integration complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system incorporates cameras that continuously monitor the gaming table surface and detect card positions. This visual feedback is processed to determine whether cards are placed in correct locations according to game rules. The system provides real-time feedback to players and dealers, enabling accurate verification of card placement while managing complexity through automated image processing rather than manual verification

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The integrated system serves multiple functions simultaneously: LED strips provide ambient illumination and guide card placement, individual lights highlight specific betting areas and card positions, cameras capture game action for both live streaming and automated card position verification, and the control system coordinates all components. This multi-functionality reduces the need for separate dedicated systems for each function

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If visual indicators are made visible from the table surface, then player guidance is improved, but the indicators may interfere with the playing surface

Engineering Contradiction:
Improvecard placement guidanceVSAvoidplaying surface interference
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The visual indicators are positioned in the vertical dimension above the playing surface rather than directly on it. LED strips are mounted along the rail structure, and individual lights are positioned above card locations. This vertical placement provides clear visual guidance for card placement while maintaining the integrity and smoothness of the playing surface, allowing cards to be freely placed without interfering with the light sources

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