Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional benchtop high pressure measurement device is used, then high pressure measurement capability is achieved, but device portability deteriorates
Solution Approach 1:
The patent combines the pressure generation function (gas cylinder), pressure control function (pressure control module with proportional valve), and pressure measurement function (pressure sensor) into a single integrated portable device. This merging eliminates the need for separate external gas cylinders and benchtop equipment, enabling high pressure measurement capability while improving portability for on-site calibration applications
2Measurement precision
If an external gas cylinder and alternating-current power supply are used for high pressure measurement, then measurement accuracy is improved, but device complexity and portability worsen
Solution Approach 1:
The patent integrates the gas cylinder, pressure control module with proportional valve, pressure sensor, and power supply into a single portable unit. This consolidation reduces device complexity by eliminating multiple external components while maintaining measurement accuracy through the integrated pressure control and measurement systems
Solution Approach 2:
The portable pressure measurement device performs multiple functions including pressure generation, pressure control, pressure measurement, and calibration within a single unit. The device can operate autonomously without external gas cylinders or power supplies, providing universal functionality for on-site high pressure measurement and calibration tasks

AI summary
A pressure measurement device is configured to adjust a gas pressure in an external gas cavity that is fluidly coupled thereto and measure the adjusted gas pressure in the external gas cavity. The pressure measurement device includes a port, a pressure control module, and a gas discharging port. The pressure measurement device is fluidly coupled to the external gas cavity through the port. The pressure control module is coupled to the port through a gas passage and configured to operably provide pressurized gas to the external gas cavity or draw gas from the external gas cavity.
