Engineering Contradiction Analysis
1Productivity
If traditional computing systems (von Neumann architecture) are used for AI processing, then general-purpose computation is achieved, but processing efficiency deteriorates and power consumption increases
Solution Approach 1:
The patent replaces traditional von Neumann architecture with a neuromorphic computing system that mimics biological neural networks. This substitution fundamentally changes the computational paradigm from sequential digital processing to parallel event-driven processing, achieving both higher efficiency and lower power consumption by eliminating the von Neumann bottleneck and using spike-based communication instead of continuous data transfer
Solution Approach 2:
The patent changes the fundamental parameters of computation by using spiking neural networks with event-driven operation. Instead of continuous clock-cycled processing, the system operates asynchronously based on spike events, changing the time parameter from fixed intervals to variable event-based timing, which improves efficiency and reduces energy consumption by processing only when necessary
2Productivity
If traditional digital computation using zeros and ones is used, then simple binary processing is achieved, but computational efficiency for AI tasks deteriorates
Solution Approach 1:
The patent introduces dynamic, event-driven computation using spiking neural networks. Instead of static binary processing, the system uses dynamic spike trains with variable timing and intensity to encode information. This dynamic approach enables more efficient AI computation by mimicking biological neural processing, where the timing and frequency of spikes carry computational meaning beyond simple binary states
