Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If model parallelism is used to accelerate AI operations, then computation speed is improved, but communication latency and data transfer volume increase
Solution Approach 1:
The patent replaces traditional electrical/optical communication systems with electromagnetic radiation-based communication. Processing units emit electromagnetic signals that propagate through space to reach other processing units, eliminating the need for physical communication channels and reducing communication latency in distributed AI systems.
Solution Approach 2:
The patent introduces spatial dimensionality by allowing electromagnetic signals to travel through three-dimensional space between processing units. This enables direct line-of-sight communication paths that bypass traditional hierarchical communication structures, reducing the number of communication hops and associated latency.
2Adaptability or versatility
If all-to-all communication is implemented among processing units, then model parallelism functionality is achieved, but energy consumption and memory load increase
Solution Approach 1:
The patent implements self-service through passive electromagnetic signal propagation. Once electromagnetic signals are emitted by processing units, they automatically propagate through space and are detected by receiving units without requiring active management, routing, or buffering infrastructure, significantly reducing energy consumption compared to traditional active communication systems.
Solution Approach 2:
The patent extracts the communication function from traditional electrical/optical channels and implements it through electromagnetic radiation in free space. This separation eliminates the energy overhead associated with maintaining physical communication infrastructure and enables more efficient all-to-all communication patterns.
