Engineering Contradiction Analysis
1Measurement precision
If machine learning algorithms use classical computing devices to perform complex statistical calculations, then decision-making accuracy is improved, but execution time and energy consumption increase
Solution Approach 1:
The patent replaces classical computing devices with a thermodynamic computing system that uses physical thermodynamic processes to perform statistical calculations. The system employs oscillators coupled through energy-based models to naturally evolve toward equilibrium states that represent probabilistic outcomes, substituting mechanical computation with physical thermodynamic evolution. This allows complex statistical calculations to be performed through natural physical processes rather than sequential computational steps.
Solution Approach 2:
The patent changes the fundamental operating parameters from digital computation to thermodynamic state evolution. By using temperature, energy levels, and oscillator frequencies as computational parameters instead of binary digits, the system achieves parallel processing of statistical calculations. The energy-based models use Hamiltonian dynamics where system energy parameters naturally encode probability distributions, enabling faster convergence to accurate statistical results.
2Use of energy by moving object
If thermodynamic computers are used to perform algorithms, then energy efficiency is improved, but communication between components requires conversion to classical form reducing efficiency
Solution Approach 1:
The patent creates a universal interface layer that allows thermodynamic components to both process information thermodynamically and communicate thermodynamically. The oscillators serve multiple functions: they process computational tasks through thermodynamic evolution and simultaneously transmit information through their thermodynamic states to other oscillators. This multi-functionality eliminates the need for separate conversion stages, maintaining energy efficiency throughout the entire computation-communication cycle.
Solution Approach 2:
The patent introduces thermodynamic relay gadgets as intermediary components that facilitate direct thermodynamic communication between energy-based models. These relay gadgets act as mediators that receive thermodynamic states from one model and transmit them to another without requiring conversion to classical form. The relay gadgets use coupled oscillators to transfer thermodynamic information, preserving the energy efficiency benefits while enabling productive communication between computational components.
3Measurement precision
If complex statistical calculations are performed using classical computing, then accurate probabilities are obtained, but energy consumption increases
Solution Approach 1:
The patent replaces energy-consuming computational algorithms with energy-efficient thermodynamic processes. Instead of using classical computing devices to calculate statistical probabilities through sequential operations, the system uses oscillators that naturally evolve according to thermodynamic laws. The probability distributions emerge directly from the thermodynamic equilibrium states of the system, eliminating the need for energy-intensive calculation algorithms while maintaining accurate probability determination.
Solution Approach 2:
The thermodynamic system performs probability calculations through self-organizing physical processes rather than externally controlled computational steps. The oscillators automatically evolve toward equilibrium states that represent accurate probability distributions through natural thermodynamic evolution. This self-service mechanism eliminates the need for external computational resources and energy consumption associated with running complex statistical algorithms on classical computing devices.
