Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If bulk optics are incorporated into ultracold matter physics systems, then light manipulation functions are achieved, but the size, weight, and power requirements increase substantially

Engineering Contradiction:

Improvelight manipulation capabilityVSAvoidsystem weight

Core Design Contradiction:

Adaptability or versatilityVSWeight of stationary object

Solution Approach 1:

The patent combines the optical element directly with the vacuum cell wall, creating an integrated structure where the lens is formed as part of the wall itself rather than being a separate component. This merging eliminates the need for additional bulk optics and reduces overall system weight while maintaining light manipulation functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent employs a thin metasurface layer integrated into the vacuum cell wall to perform optical functions. This thin-film approach replaces bulky traditional optics with a lightweight metasurface structure that achieves the same light manipulation capabilities with minimal added mass.

Inventive Principle:

Principle #30Flexible shells and thin films

2Adaptability or versatility

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The optical element is merged with the vacuum cell wall structure, eliminating the need for separate bulk optics and reducing the overall system volume. The lens functionality is achieved through a thin integrated layer rather than thick standalone optical components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

A thin metasurface film is used instead of bulky bulk optics, achieving the same optical manipulation functions with minimal volume addition. This thin-film approach allows the system to maintain compact dimensions while providing necessary light control capabilities.

Solution Approach 1:

The integrated metasurface-lens structure eliminates the need for separate bulk optics and their associated mounting, alignment, and support systems that would consume additional power. The merged structure reduces overall system complexity and power requirements.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The thin metasurface film requires minimal power for operation compared to bulky optical systems that may require active adjustment mechanisms, cooling systems, and complex alignment systems. The passive metasurface structure reduces overall power consumption.

AI summary

Metamaterial optics are integrated with vacuum-boundary walls of ultra-high-vacuum (UHV) cells to manipulate light in a manner analogous to various bulk optical elements including lenses, mirrors, beam splitters, polarizers, waveplate, wave guides, frequency modulators, and amplitude modulators. For example, UHV cells can have metasurface lenses formed on interior and/or exterior surfaces on one or more of their vacuum-boundary walls. Each metasurface lens can include a plurality of mesas with the same height and various cross-sectional dimensions. The uses of metasurface lenses allows through-going laser beams to be expanded, collimated or focused without using bulky refractive optics. Each metasurface lens can be formed on a cell wall using photolithographic or other techniques.
