Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional ultrasonic flow rate measurement devices are configured with modified measurement flow paths and coupling configurations to adapt to different piping and installation sites, then measurement accuracy is improved, but device complexity and development time increase
Solution Approach 1:
The patent applies universality by designing a standardized measurement flow path configuration that can be used across different piping and installation scenarios. The flow path includes standardized coupling parts (inlet-side and outlet-side) that can adapt to various pipe types without requiring custom modifications, making the device universally applicable while maintaining measurement accuracy
Solution Approach 2:
The measurement flow path is segmented into standardized modular components including inlet-side coupling parts, outlet-side coupling parts, and intermediate flow path sections. This segmentation allows the device to be assembled in different configurations to suit various installation sites without redesigning the entire system, reducing complexity while preserving accuracy
2Measurement precision
If conventional ultrasonic flow rate measurement devices are customized for different piping and installation sites, then measurement accuracy is improved, but development time and costs increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring the measurement flow path with standardized coupling parts and flow path geometries that are optimized for measurement accuracy in advance. This preliminary standardization eliminates the need for time-consuming custom modifications during installation, as the device is already prepared to work with various piping configurations
Solution Approach 2:
The standardized measurement flow path design serves multiple installation scenarios simultaneously, allowing a single device configuration to be deployed across different piping types and installation sites without requiring separate development cycles for each application
3Measurement precision
If conventional ultrasonic flow rate measurement devices require modifications based on installation sites, then measurement accuracy is improved, but ease of manufacture decreases
Solution Approach 1:
The measurement flow path is divided into standardized manufactured segments including inlet coupling parts, outlet coupling parts, and intermediate sections. Each segment can be manufactured independently using standardized processes, then assembled to create the complete measurement device, simplifying manufacturing while ensuring consistent measurement accuracy
Solution Approach 2:
The standardized measurement flow path components are designed to be universally manufacturable using common fabrication processes, eliminating the need for custom tooling or specialized manufacturing steps for different installation scenarios, thereby improving ease of manufacture while maintaining accuracy
