Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotary wheel component is used for card shuffling, then the device can randomly select cards, but wear patterns develop over time causing biases in stopping points
Solution Approach 1:
The wheel assembly is divided into multiple segments or sections that can be independently worn or replaced. The card shuffling device includes a wheel assembly with multiple radial segments that can be rotated, allowing specific worn segments to be replaced without replacing the entire wheel structure.
Solution Approach 2:
The patent implements a system where worn wheel segments or components can be discarded and replaced with fresh ones. The wheel assembly includes replaceable segments that maintain randomness over extended periods, recovering the randomness property after wear occurs.
2Ease of operation
If rotary components are used for card shuffling, then the device operates simply, but wear patterns create biases that affect game integrity
Solution Approach 1:
The wheel assembly incorporates asymmetric features or non-uniform spacing of card positions to prevent predictable wear patterns from creating biases. The asymmetric design ensures that even with wear, stopping points remain uniformly distributed.
Solution Approach 2:
The device includes preliminary measures such as pre-wearing in periods or preliminary rotation sequences that distribute wear evenly across all wheel segments before actual use, preventing localized wear patterns from developing biases.
3Device complexity
If existing card shuffling devices are used, then the structure is simple, but durability is reduced due to wear
Solution Approach 1:
The wheel assembly is segmented into multiple replaceable sections that can be individually maintained or replaced. This segmentation extends the overall device lifespan by allowing targeted replacement of worn segments rather than the entire wheel assembly.
Solution Approach 2:
The patent introduces dynamic maintenance capabilities where the wheel assembly can be adjusted, rotated, or reconfigured during operation or maintenance periods. This dynamic approach extends operational lifespan by adapting to wear conditions.
