Solution Overview
Problem
Existing dielectric property measurement methods using balanced-type circular disk resonators face challenges in accurately measuring dielectric properties at high frequencies due to temperature dependency errors caused by excitation wires, which require complex correction procedures and prolonged measurement times.
Innovation Solution
Incorporating a temperature adjustment unit coupled to the conductive member of the balanced-type circular disk resonator to adjust the temperature of the dielectric boards independently, eliminating the need for an isothermal bath and reducing exposure of excitation wires to heat, thus minimizing measurement errors and shortening measurement time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an isothermal bath is used to maintain temperature, then measurement accuracy is improved, but device complexity and measurement time increase
Solution Approach 1:
The patent extracts the temperature control function from the complex isothermal bath system and implements it locally through a temperature adjustment unit coupled to the conductive member. This allows temperature control to be achieved independently for each dielectric board without requiring a comprehensive isothermal environment, thereby reducing overall system complexity while maintaining measurement accuracy.
Solution Approach 2:
The patent segments the temperature control into independent units for each dielectric board through the conductive member structure. Instead of controlling the entire measurement environment temperature uniformly, each board can be temperature-adjusted separately, simplifying the overall system architecture and reducing measurement time.
2Temperature
If excitation wires are exposed to heat, then temperature adjustment is achieved, but measurement errors increase due to temperature dependency
Solution Approach 1:
The patent introduces a temperature adjustment unit as an intermediary between the heat source and the dielectric board. This unit allows precise temperature control of the dielectric board while minimizing heat exposure to the excitation wires, thereby reducing temperature-dependent measurement errors while achieving the desired temperature adjustment.
3Measurement precision
If complex correction procedures are implemented, then measurement accuracy is improved, but measurement time and operational complexity increase
Solution Approach 1:
The patent performs temperature adjustment of the dielectric board before the actual measurement process through the temperature adjustment unit. By pre-establishing the correct temperature conditions, the need for complex post-measurement correction procedures is eliminated, thereby maintaining measurement accuracy while significantly reducing total measurement time.
4Stability of the object's composition
If an isothermal bath is used, then temperature stability is improved, but ease of operation deteriorates due to prolonged measurement time
Solution Approach 1:
The patent implements a self-service temperature control mechanism where the temperature adjustment unit is directly coupled to the conductive member and dielectric board. This allows the system to automatically maintain temperature stability without requiring complex external isothermal bath equipment or prolonged measurement procedures, thereby improving both temperature stability and operational simplicity.
