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 increases
Solution Approach 1:
The patent replaces traditional electrical signal transmission through wires with optical signal transmission using electromagnetic radiation (light). Processing units project electromagnetic radiation onto a shared surface to communicate data, substituting the mechanical/electrical communication infrastructure with an optical system that eliminates wire-related latencies and enables parallel communication without interference.
Solution Approach 2:
The patent introduces a spatial dimension to communication by using a shared surface (such as a screen or wall) as an intermediate medium. Instead of direct point-to-point communication between processing units, data is projected onto the surface and captured from there, creating a new communication dimension that allows multiple units to communicate simultaneously without direct connectivity between each pair.
2Adaptability or versatility
If all-to-all communication is performed among processing units, then model parallelism functionality is achieved, but energy consumption increases
Solution Approach 1:
The patent replaces high-power electrical signal transmission with optical signal transmission. By using electromagnetic radiation (light) instead of electrical currents through complex wiring, the system achieves the same all-to-all communication functionality with significantly lower energy consumption, as optical transmission requires less power and generates less heat.
Solution Approach 2:
The shared surface serves multiple functions simultaneously: it acts as a communication medium for all processing units, a data storage buffer, and a synchronization point. This multi-functionality eliminates the need for separate dedicated communication channels between each pair of processing units, reducing overall system energy consumption while maintaining full model parallelism capabilities.
3Ease of operation
If extensive wiring is used for communication among processing units, then data transmission is enabled, but device complexity increases
Solution Approach 1:
The patent eliminates the complex web of wires and cables that would be required for all-to-all communication between processing units by substituting it with an optical projection system. Processing units use projectors to send data as electromagnetic radiation onto a shared surface, and cameras or sensors to receive data from the surface, completely removing the need for physical wiring infrastructure.
Solution Approach 2:
The shared surface (screen, wall, or display) serves as an intermediary medium that facilitates communication between processing units without requiring direct connections. Each unit projects data onto the surface and reads data from the surface, using the surface as a universal interface that simplifies the communication architecture and eliminates complex wiring requirements.
