Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional true random number generators use physical means (radiation decay, thermal noise, oscillator imperfections), then true randomness is achieved, but the devices become bulky and require complex setup/maintenance
Solution Approach 1:
The patent replaces complex mechanical/physical random number generation systems with a simplified electromechanical system using dice in a fluid container. The mechanical agitation system combined with optical detection (cameras) substitutes for traditional physical phenomena like radiation decay or thermal noise, achieving true randomness with reduced complexity and bulk.
Solution Approach 2:
The patent introduces a fluid as an intermediary medium between the mechanical agitation and the random outcome. The fluid facilitates the chaotic motion of dice, translating mechanical energy into stochastic behavior that can be captured optically, thereby simplifying the overall system architecture while maintaining true randomness.
2Reliability
If conventional true random number generators use physical means (radiation decay, thermal noise, oscillator imperfections), then true randomness is achieved, but the devices become too slow and inefficient
Solution Approach 1:
The patent employs periodic mechanical agitation of the dice in the fluid container, combined with continuous optical capture. This periodic action allows for rapid generation of random numbers by repeatedly agitating the system and capturing images at high frames per second, significantly improving generation speed while maintaining true randomness through the chaotic fluid dynamics.
Solution Approach 2:
The system maintains continuous useful action through ongoing mechanical agitation and continuous optical capture. The fluid remains in constant motion, and the camera continuously records the dice positions, enabling uninterrupted generation of high-quality random numbers at high speed without the intermittent limitations of traditional physical methods.
3Device complexity
If pseudorandom number generators are used, then device simplicity is maintained, but true randomness is lost which is essential for cryptographic applications
Solution Approach 1:
The system uses self-service principles by allowing the mechanical agitation and fluid dynamics to naturally generate chaos without external intervention. The dice randomly tumble in the fluid due to the agitation forces, creating inherently unpredictable outcomes that are captured optically. This self-generated chaos provides true randomness while keeping the system relatively simple.
4Reliability
If conventional true random number generators are used, then high-quality entropy is produced, but the devices are too bulky for data centers
Solution Approach 1:
The patent segments the random number generation function into distinct modular components: a compact fluid container holding dice, a separate mechanical agitation mechanism, and an optical capture system. This segmentation allows each component to be optimized independently and assembled into a compact unit suitable for data center integration while maintaining high-quality entropy generation.

AI summary
An apparatus generates truly random numbers. The apparatus includes a container that is at least partially filled with a fluid (e.g., water or air). The apparatus also includes objects (e.g., dice) suspended freely in the fluid. The apparatus includes agitators configured to stir the fluid, and cameras configured to capture images of the objects. When the agitators stir the fluid, the objects move freely (e.g., move with the created currents) in the fluid in the container. The apparatus also includes a random number generation circuit coupled to the cameras. The random number generation circuit is configured to generate random numbers based on the images captured by the cameras.
