Solution Overview
Problem
The existing transverse magnetic mode dielectric resonators face challenges with thermodynamic deformation, leading to assembly precision issues and reduced soldering reliability due to the use of thin metal sheets that are difficult to assemble and prone to excessive deformation during machining.
Innovation Solution
The use of elastic materials for both the cover and baseplate, which absorb thermodynamic deformation, eliminating the need for precise fitting slots and ensuring reliable soldering by using printed circuit boards with conductive layers and plated through holes for electrical conductivity and deformation absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thin metal sheets are used to absorb thermodynamic deformation, then the resonant dielectric rod is protected from shattering, but assembly precision deteriorates and soldering reliability decreases
Solution Approach 1:
The patent changes the material parameter from rigid metal sheets to elastic material with appropriate mechanical properties. The elastic material absorbs thermodynamic deformation through elastic deformation rather than requiring precise fitting slots, thereby protecting the resonant dielectric rod while maintaining assembly precision and soldering reliability.
Solution Approach 2:
The patent uses composite material structure where the cover and baseplate are made of elastic material that combines the benefits of metal (structural support) with elastic properties (deformation absorption). This composite approach eliminates the need for thin metal sheets while maintaining both protection and precision.
2Object-affected harmful factors
If thin metal sheets are used for deformation absorption, then thermodynamic deformation is mitigated, but device complexity increases due to precise fitting requirements
Solution Approach 1:
The patent changes the mechanical parameter of the cover and baseplate from rigid to elastic, enabling them to absorb thermodynamic deformation through material elasticity rather than through complex precise fitting structures. This simplifies the device while effectively mitigating deformation.
3Reliability
If thin metal sheets are used to absorb deformation, then the resonant dielectric rod is protected, but material costs and machining difficulty increase
Solution Approach 1:
The patent employs elastic material for the cover and baseplate that can be manufactured using standard PCB fabrication processes rather than requiring precision machining of thin metal sheets. This reduces both material costs and machining difficulty while maintaining protection of the resonant dielectric rod.
