Engineering Contradiction Analysis
1Productivity
If voltage signals are used for signal transmissions and computations in electronic computers, then the system can perform arithmetic and comparison operations, but only a single sequence of potential signals can be transmitted at a time in a single circuit channel, limiting computing speed
Solution Approach 1:
The patent transitions from temporal multiplexing (single signal sequence over time) to spatial/frequency multiplexing (multiple signal sequences simultaneously across different optical channels). By using multiple optical channels carrying different frequency signals parallel to each other, the system achieves concurrent data transmission without increasing temporal complexity, thus resolving the contradiction between computing speed and device complexity.
2Productivity
If quantum computers are developed for high-speed computations, then computing performance can be significantly improved, but they require quantum superposition and entanglement conditions with extremely low temperatures close to absolute zero, resulting in exceedingly high costs
Solution Approach 1:
The patent replaces the quantum mechanical system (requiring superposition, entanglement, and cryogenic temperatures) with an optical system using classical light waves. By substituting quantum states with optical frequency signals that can be transmitted through standard optical channels at room temperature, the system achieves high-speed computation capabilities without the extreme environmental requirements and associated costs of quantum computing infrastructure.
3Productivity
If multiple frequency optical signals are transmitted simultaneously through the optical path module, then concurrent data access and processing can be enabled without interference, but the system complexity increases
Solution Approach 1:
The patent segments the data transmission task by assigning different frequency bands to different data streams. Each optical channel carries a specific frequency signal, allowing simultaneous transmission of multiple data sequences. The optical processing module then processes each frequency channel independently, dividing the complex task into manageable parallel operations that can be handled simultaneously without mutual interference.
