Trigger-Synchronized Pressure Measurement System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure measurement systems face challenges in accurately performing inspection and calibration due to fluctuations in pressure measurements caused by unstable fluid pressure and environmental factors, which limits the accuracy and increases costs, especially when requiring controlled environments and skilled operation for dead weight pressure balances.
Innovation Solution
A measurement system that synchronizes the measurement timing of pressure measurement devices using a trigger signal, allowing them to measure pressure at the same designated time, reducing the impact of pressure fluctuations and eliminating the need for constant temperature chambers and skilled operation, thereby improving accuracy and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pressure measurement is performed using conventional methods without synchronized timing, then measurement can be performed continuously, but measurement accuracy deteriorates due to pressure fluctuations and environmental factors
Solution Approach 1:
The system performs preliminary actions by pre-synchronizing the measurement timing of all pressure measurement devices using a trigger signal before actual pressure measurements are taken. This ensures that all devices measure at the same moment, eliminating errors caused by pressure fluctuations during the measurement process, while maintaining simple device architecture
2Measurement precision
If dead weight pressure balances are used for calibration, then calibration accuracy can be improved, but operational difficulty and cost increase due to requiring skilled operation and controlled environments
Solution Approach 1:
The patent replaces the complex mechanical dead weight pressure balance system with an electronic synchronization system using trigger signals and digital timing control. This substitution maintains high calibration accuracy through precise timing synchronization while dramatically simplifying operation and eliminating the need for skilled manual operation and controlled environmental conditions
3Stability of the object's composition
If constant temperature chambers are used for pressure measurement, then measurement stability is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts and removes the constant temperature chamber from the measurement system by replacing it with a trigger-based synchronization mechanism. This extraction eliminates the need for complex environmental control equipment while maintaining measurement stability through precise temporal synchronization of all measurement devices
