Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software algorithms are used to generate random numbers, then the generation process is simple and fast, but the random numbers show regularity and bias making them vulnerable to security breaches
Solution Approach 1:
The patent replaces software-based random number generation with a hardware-based system using radioactive decay detection. The particle detector, pulse generator, clock counter, and random number converter form a hardware system that detects physical random phenomena (radioactive decay) to generate true random numbers, eliminating the regularity and bias inherent in software algorithms while maintaining security reliability
Solution Approach 2:
The patent adjusts the clock frequency parameter dynamically based on the detected particle intervals. The random number converter modifies the clock frequency according to the minimum and maximum count values obtained from detecting radioactive decay events, thereby adapting the system parameters to optimize both security and generation speed while maintaining true randomness
2Reliability
If true random numbers are generated using hardware-based random phenomena, then the quality and security are improved, but the generation speed is reduced
Solution Approach 1:
The patent implements continuous random number generation by continuously detecting particle emissions from the radioactive isotope and continuously updating the random number output. The system maintains uninterrupted operation where the particle detector continuously monitors for decay events, the clock counter continuously counts clock signals during pulse intervals, and the random number converter continuously generates and outputs random numbers, thereby achieving both high quality and high generation speed
Solution Approach 2:
The patent introduces dynamic adjustment of the clock frequency based on real-time detection results. The random number converter modifies the clock frequency according to the detected particle intervals and count values, allowing the system to adaptively optimize the generation speed while maintaining true randomness. This dynamic parameter adjustment enables the system to respond to varying detection conditions and maximize both speed and quality
3Reliability
If the clock frequency is adjusted based on detected particle intervals, then the quality and unbiased nature of random numbers is improved, but the device complexity increases
Solution Approach 1:
The system performs self-adjustment of the clock frequency based on its own detection results. The particle detector detects particle intervals, the clock counter measures time intervals, and the random number converter automatically adjusts the clock frequency without external intervention. This self-service mechanism eliminates the need for complex external control systems while achieving unbiased random number generation through automatic parameter optimization

AI summary
A random number generating device includes a particle detector, a pulse generator, a clock counter, and a random number converter. The particle detector detects particles emitted from a radioactive isotope. The pulse generator generates pulses corresponding to the particles. The clock counter counts the number of clock cycles during time intervals between the pulses and generates a plurality of count values. The random number converter adjusts a clock frequency, based on a minimum value and a maximum value of the plurality of count values and converts a target count value generated depending on the adjusted clock frequency into a random number.
