Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If standard CMOS logic gates are used for computation, then the circuit operates sequentially with simple forward logic, but it requires exponentially growing resources to solve NP problems
Solution Approach 1:
The patent applies reverse logic by allowing logic gates to operate in both forward and reverse directions simultaneously. The reverse logic operation enables the system to search for solutions by working backward from desired outputs, fundamentally changing the sequential forward-only computation model to a bidirectional approach that can solve NP problems more efficiently
Solution Approach 2:
The patent introduces dynamic behavior through memristive devices that can switch between different resistance states and operate in both forward and reverse modes. This dynamic capability allows the circuit to adapt its operation mode based on computational needs, enabling polynomial resource usage for NP problems by switching between forward and reverse logic operations
2Speed
If standard logic gates operate sequentially, then the circuit structure is simple, but the computation time grows exponentially for NP problems
Solution Approach 1:
By implementing reverse logic operations, the patent enables the circuit to perform computations in both forward and reverse directions simultaneously. This inversion of the traditional sequential approach allows the system to explore solution spaces more efficiently, reducing computation time for NP problems from exponential to polynomial growth
Solution Approach 2:
The patent achieves continuous useful action by enabling simultaneous forward and reverse logic operations within the same circuit. This continuous bidirectional computation eliminates idle time between sequential operations, maintaining productive computation throughout the solution process and significantly reducing overall computation time
3Adaptability or versatility
If forward logic only is used, then the circuit design is straightforward, but it cannot efficiently solve complex NP problems
Solution Approach 1:
The patent implements universal logic gates that can perform both forward and reverse logic operations. This multi-functionality allows a single circuit design to handle diverse computational tasks including both forward propagation and reverse search operations, greatly enhancing adaptability for solving various NP problems without requiring separate specialized circuits
Solution Approach 2:
The patent extends basic logic gate functionality by enabling reverse operations in addition to forward operations. This inversion capability transforms simple unidirectional logic gates into bidirectional universal gates, significantly increasing versatility while maintaining a relatively straightforward circuit design based on extended standard logic gate principles
