Engineering Contradiction Analysis
1Ease of manufacture
If existing dielectric EM device structures are used, then the devices can function as dielectric resonators, but the fabrication process becomes difficult and manufacturing efficiency is reduced
Solution Approach 1:
The dielectric body is divided into multiple dielectric portions (first dielectric portion, second dielectric portion, etc.) with constant cross-sectional profiles along different linear axes. This segmentation allows each portion to be independently characterized and potentially manufactured, simplifying the overall fabrication process while maintaining the complex resonator functionality.
Solution Approach 2:
The patent introduces a third dimension by specifying that cross-sectional profiles are constant along linear axes, effectively creating extruded or prismatic dielectric structures. This dimensional approach simplifies manufacturing by reducing the problem from fully 3D complex shaping to 2D profile extrusion along a linear axis, making the fabrication process more tractable.
2Productivity
If dielectric portions with varying cross-sections are used, then complex EM resonator performance can be achieved, but manufacturing efficiency decreases
Solution Approach 1:
Each dielectric portion is assigned a constant cross-sectional profile along its specific linear axis, creating local uniformity within each portion. This local quality approach ensures that the dielectric constant remains consistent throughout each portion's length, meeting manufacturing precision requirements while enabling efficient production through standardized profiling.
Solution Approach 2:
The patent changes the geometric parameters of the dielectric portions by enforcing constant cross-sectional profiles along linear axes. This parameter constraint transforms the manufacturing problem from one requiring variable cross-section control to one requiring only constant profile maintenance, significantly improving manufacturing efficiency while preserving the necessary dielectric constant consistency for resonator performance.
