Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional beam delivery systems are used, then the system structure is simple, but the system cannot provide optical beams for interacting with a large number of quantum objects while meeting design requirements
Solution Approach 1:
The patent transitions from single-layer photonic routing to three-dimensional integrated optical paths, adding vertical dimensionality with multiple layers (first layer with waveguides, second layer with signal manipulation elements). This enables simultaneous interaction with multiple quantum objects by routing optical beams through different spatial layers, thereby increasing productivity without proportionally increasing complexity.
Solution Approach 2:
The system divides the photonic routing function into segmented components: waveguides for signal transmission, grating couplers for signal coupling, and metasurfaces for beam shaping. Each component performs a specific function, allowing the system to handle multiple quantum objects through dedicated optical paths while maintaining manageable complexity through functional segmentation.
2Adaptability or versatility
If single-layer photonic routing is used, then the device structure is simple, but cross-talk issues and limited design space occur
Solution Approach 1:
By implementing multi-layer three-dimensional routing, the patent expands the design space vertically. The first layer contains waveguides while the second layer contains signal manipulation elements, allowing optical beams to be routed to multiple target locations without cross-talk by separating functions across layers. This dimensional expansion provides greater adaptability for interacting with different quantum object configurations.
3Productivity
If multiple signal manipulation elements are integrated, then photonic signals can be delivered to multiple target locations efficiently, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into integrated three-dimensional optical paths that simultaneously perform signal transmission, coupling, and manipulation. By combining waveguides, grating couplers, and metasurfaces into a unified multi-layer structure, the system achieves efficient signal delivery to multiple targets while consolidating complexity into an integrated architecture rather than separate discrete components.
