Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mechanical flow rate measurement devices are used, then flow rate data can be obtained, but the devices require regular maintenance and are prone to mechanical failure
Solution Approach 1:
The patent replaces mechanical measurement mechanisms with electronic sensors and computational algorithms. Flow rate is determined by processing signals from multiple sensors (pressure, temperature, flow sensors) using a microprocessor, eliminating moving parts and mechanical wear while maintaining measurement accuracy.
Solution Approach 2:
The patent introduces electronic sensors and a microprocessor as intermediaries between the fluid flow and the measurement output. Instead of direct mechanical interaction, sensors detect flow parameters and the microprocessor computes flow rate, isolating the measurement system from mechanical failure modes.
2Measurement precision
If mechanical flow rate measurement devices are used, then flow rate data can be obtained, but the devices can interfere with the actual fluid flow by causing turbulence or undesired pressure drops
Solution Approach 1:
The patent replaces intrusive mechanical measurement elements with electronic sensors that can be positioned to minimize flow disruption. The measurement system uses electrical/electronic fields rather than mechanical obstructions, reducing turbulence and pressure drops while maintaining measurement capability.
3Reliability
If a sensor-based apparatus is used, then maintenance requirements are reduced, but device complexity increases due to electronic components
Solution Approach 1:
The patent combines multiple sensors (pressure, temperature, flow sensors) and computational functions into a single integrated measurement apparatus. The microprocessor consolidates data processing from multiple sensors, and the housing unifies all components, reducing overall system complexity despite the advanced functionality.
4Measurement precision
If mechanical flow rate measurement devices are used, then flow rate measurement is achieved, but the devices are not scalable to multiple sizes of fluid transportation structures
Solution Approach 1:
The patent designs the measurement apparatus with universal adaptability through adjustable sensor positions, configurable measurement parameters, and a microprocessor that can be programmed for different flow conditions and pipe configurations. This allows the same device to measure flow rates across various sizes of fluid transportation structures.
