Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional microwave resonators are used, then resonant field confinement is achieved, but the device size becomes large (10 cc-100 cc or larger)
Solution Approach 1:
The resonator is divided into multiple dielectric resonator members (first and second resonator members) that are spatially offset from each other. This segmentation allows the electromagnetic field to be confined in the spatial interaction region between the members, achieving compact size while maintaining high quality factor through the distributed resonant structure.
Solution Approach 2:
The patent transitions from a single bulky resonator to a multi-member spatial configuration where the field is confined in the gap region between members. This dimensional reorganization allows the resonant field to be concentrated in a small volume between the members rather than distributed throughout a large single resonator volume.
2Loss of energy
If conventional microwave resonators are used, then resonant field confinement is achieved, but energy losses increase
Solution Approach 1:
The patent employs dielectric resonator members with high dielectric constants to concentrate the electromagnetic field energy locally in the spatial interaction region. This local field confinement reduces energy losses by keeping the field confined to regions with low loss characteristics, thereby improving the quality factor.
Solution Approach 2:
The use of dielectric materials with specific properties (high dielectric constant, low loss tangent) for the resonator members creates a composite resonant structure. This composite approach allows optimization of both field confinement and loss reduction by selecting materials with complementary properties.
3Volume of moving object
If resonator size is reduced, then compactness is achieved, but field sensing precision deteriorates
Solution Approach 1:
The patent utilizes resonant oscillation of the electromagnetic field in the spatial interaction region between the dielectric members. This resonant enhancement concentrates field energy in a compact volume, maintaining high field intensities that enable precise sensing despite the reduced overall device size.
Solution Approach 2:
By adjusting the spatial offset distance between the dielectric resonator members and their geometric parameters, the patent optimizes the resonant frequency and field confinement characteristics. This parameter optimization allows compact dimensions while maintaining sufficient field intensities for high-precision sensing applications.

AI summary
A microwave resonator device including a first resonator member comprised of a dielectric material and a second resonator member comprised of a dielectric material. The second resonator member can be positioned spatially offset from the first resonator member to define a spatial interaction region configured to confine an electromagnetic field in a microwave region of the electromagnetic spectrum. The spatial offset between the first resonator member and the second resonator member defining the spatial interaction region is less than the microwave wavelength associated with a resonant frequency of the microwave resonator device. The microwave resonator device facilitates generation of a resonant field enhancement within the spatial interaction region.
