Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If large atomic ovens are used to provide atomic objects to the atomic system, then the atomic object supply is sufficient, but the vacuum quality deteriorates and heat load increases
Solution Approach 1:
The patent merges the atomic source device with the confinement apparatus by integrating a source assembly, object storage assembly, and coupling assembly into a unified structure. This integration allows the atomic source to be positioned close to the confinement region without requiring a separate large atomic oven, thereby maintaining vacuum quality while providing sufficient atomic objects.
Solution Approach 2:
The patent implements a nested structure where the source assembly is positioned within or adjacent to the confinement apparatus, with the object storage assembly containing the source assembly and the coupling assembly connecting them. This nesting allows compact arrangement of components, reducing the overall footprint and minimizing heat load on the atomic system while ensuring adequate atomic object supply.
2Temperature
If atomic ovens are placed close to the atomic system, then heat load is reduced, but vacuum quality deteriorates
Solution Approach 1:
The patent segments the atomic source system into distinct functional components: a source assembly for generating atomic objects, an object storage assembly for holding and releasing atoms, and a coupling assembly for transporting atoms to the confinement region. This segmentation allows each component to be optimized independently, enabling close positioning to reduce heat load while maintaining vacuum quality through proper design of each segment.
Solution Approach 2:
The patent introduces an object storage assembly as an intermediary between the source assembly and the confinement apparatus. This intermediary component can be designed to minimize thermal coupling while maintaining efficient atomic object transfer, thereby reducing heat load on the atomic system without compromising vacuum quality.
3Productivity
If additional systems like magneto-optical traps are added to transport atomic objects, then transport efficiency improves, but system complexity and vacuum compromise increase
Solution Approach 1:
The patent combines the functions of atomic object generation, storage, and transport into a single integrated device. The source assembly generates atomic objects, the object storage assembly holds and releases them, and the coupling assembly transports them to the confinement region, eliminating the need for separate magneto-optical traps and reducing system complexity while maintaining transport efficiency.
Solution Approach 2:
The integrated atomic source device performs multiple functions within a single structure: it acts as an atomic source, an object storage mechanism, and a transport system. This multi-functionality reduces the number of separate components needed, simplifying the overall system while maintaining efficient atomic object delivery to the confinement apparatus.
