Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a structure for interrogating quantum dipolar gases is formed, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The device is divided into separate functional modules: a U-shaped cell for containing quantum gas, waveguides for signal transmission, a multi-layer substrate with antennas, and transmitter/receiver dies. This segmentation allows each component to be optimized independently while maintaining overall system precision for quantum gas interrogation.
Solution Approach 2:
The patent employs a multi-layer substrate architecture where transmitter and receiver antennas are positioned on different layers of the substrate. This three-dimensional arrangement enables efficient electromagnetic coupling with the quantum gas in the U-shaped cell while managing signal interference and reducing device footprint.
2Measurement precision
If signal transmission efficiency is improved, then measurement precision is improved, but loss of energy increases
Solution Approach 1:
Waveguides are introduced as intermediary components to couple the transmitter and receiver antennas to the U-shaped cell containing quantum gas. These waveguides provide controlled electromagnetic field pathways that minimize signal loss and energy dissipation while enabling efficient interrogation of the quantum gas.
Solution Approach 2:
The multi-layer substrate uses thin dielectric films and metallic layers to create transmission pathways for electromagnetic signals. These thin-film structures minimize energy loss through optimized dielectric properties and controlled impedance matching, maintaining signal integrity from antennas to waveguides.
