Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid density measurement techniques lack precision due to variations in pressure applied to liquid samples, leading to inconsistent density readings, as the amount of force exerted on samples with gas bubbles is not accurately quantified.
Innovation Solution
A modified piston assembly with a force management system, including a coil spring and calibrated markings, is used to quantify and control the force applied to the liquid sample, ensuring consistent pressure and accurate density measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pressurized devices are used to measure fluid density, then gas bubbles are minimized and measurement accuracy is improved, but variations in applied force cause inconsistency in density readings
Solution Approach 1:
The patent applies parameter changes by introducing a force management system with calibrated markings that quantifies and standardizes the force parameter applied during pressurization. This ensures consistent force application across different tests and operators, resolving the inconsistency issue while maintaining the accuracy benefits of pressurized measurement.
Solution Approach 2:
The calibrated markings on the piston assembly provide visual feedback about the force being applied, allowing operators to verify and adjust their force application to match target values. This feedback mechanism ensures consistent force application and improves reliability of density readings.
2Measurement precision
If force is applied to compress gas bubbles in the liquid sample, then density measurement accuracy is improved, but the amount of force varies between tests and operators
Solution Approach 1:
The force management system with calibrated markings enables the device to self-regulate force application. The markings provide built-in guidance that allows any operator to apply the correct force without requiring specialized training or experience, making the process self-service and consistent across different users.
3Device complexity
If manual force application is used to pressurize the sample, then device complexity is minimized, but force quantification and control are lacking
Solution Approach 1:
The calibrated markings serve as an intermediary between the operator's manual force application and the required force quantification. Instead of adding complex electronic sensors or actuators, the patent uses a simple visual reference system that mediates the force application process, providing quantification without significantly increasing device complexity.
