Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional Faraday cages are used to shield electric fields, then electric field shielding is improved, but optical access is restricted
Solution Approach 1:
The patent applies local quality by making only specific regions of the housing transparent (optical windows) while keeping other regions opaque for shielding. This allows electric field shielding in most areas while maintaining optical access at specific locations where measurement and manipulation light beams need to pass through.
Solution Approach 2:
The patent uses asymmetric design by incorporating transparent electrodes with conductive coatings on optical windows. These transparent electrodes provide electric field control functionality while maintaining optical transparency, creating an asymmetric structure that combines shielding and optical access properties in different parts of the same component.
2Illumination intensity
If transparent electrodes with conductive coatings are used, then optical access is improved, but electric field control complexity increases
Solution Approach 1:
The patent applies universality by designing the transparent electrode to perform multiple functions simultaneously: it serves as both an optical window for light beam passage and an electric field control element through its conductive coating. This multi-functional design reduces the need for separate components and simplifies the overall system architecture.
Solution Approach 2:
The patent merges the optical window function and the electric field control function into a single integrated component - the transparent electrode with conductive coating. By combining these functions, the patent reduces device complexity compared to using separate transparent windows and separate electrode structures.
3Adaptability or versatility
If Rydberg states are used for quantum operations, then quantum computing capability is improved, but sensitivity to electric fields increases
Solution Approach 1:
The patent applies feedback by using control electrodes to actively monitor and adjust electric fields in real-time. The transparent electrodes with conductive coatings can detect electric field variations and allow for compensatory adjustments, providing feedback control that stabilizes the electric field environment for sensitive Rydberg atom operations.
Solution Approach 2:
The patent applies preliminary anti-action by using the control electrodes to preemptively counteract stray electric fields before they can interfere with Rydberg atom operations. The electrodes are positioned and configured to generate opposing electric fields that cancel out harmful stray fields, protecting the quantum operations in advance.
