Engineering Contradiction Analysis
1Reliability
If two bonded wafers are used to create a hermetically sealed cavity, then gas purity can be maintained, but the manufacturing process becomes complex and the device is more sensitive to environmental factors
Solution Approach 1:
The patent changes the manufacturing parameters and materials from bonded wafers to a single glass vial sealed with laser welding, simplifying the process while maintaining hermetic seal integrity and gas purity over time
Solution Approach 2:
The invention extracts the bonding interface from the system by using a single-piece glass vial construction, eliminating the complex wafer bonding process and associated environmental sensitivity while preserving the hermetic seal function
2Reliability
If two bonded wafers are used to create a hermetically sealed cavity, then gas purity can be maintained, but the device requires complex manufacturing processes
Solution Approach 1:
The patent changes the manufacturing approach from complex wafer bonding to simple glass vial fabrication with laser sealing, dramatically improving ease of manufacture while maintaining hermetic integrity and gas purity
Solution Approach 2:
The glass vial construction uses simpler, more readily available materials and processes compared to precision bonded wafers, making the device easier and more cost-effective to manufacture while achieving the same hermetic seal function
3Volume of moving object
If the vial walls are made thinner to reduce size, then the device becomes more compact, but gas purity maintenance becomes more difficult
Solution Approach 1:
The patent uses thin glass vial walls that are sufficiently thin to achieve compact size while maintaining hermetic integrity through laser sealing technology, balancing compactness with gas purity maintenance capability
Solution Approach 2:
The invention replaces mechanical bonding interfaces with laser welding/sealing, allowing thinner wall construction without compromising the hermetic seal, thus enabling compact size while maintaining gas purity
4Volume of moving object
If the vial is made smaller for integration, then device size is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent changes the manufacturing parameters to use laser cutting and sealing processes that can achieve high precision in small vial fabrication, allowing reduced size without sacrificing manufacturing quality
Solution Approach 2:
The invention substitutes traditional mechanical sealing methods with laser welding, which provides superior precision and repeatability for small-scale vial fabrication, enabling miniaturization while maintaining manufacturing precision

AI summary
In one example, a method comprises filling a tube made of a same material with a dipolar gas; sealing a portion of the tube to form a container enclosing the dipolar gas. The method further comprises forming an electromagnetic reflective coating inside or outside the container, the electromagnetic reflective coating having an opening; and positioning an antenna at the opening.
