Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate level probes are used, then level detection function is provided, but device complexity and installation complexity increase
Solution Approach 1:
The patent combines the level detection device with the electric immersion pump into a single integrated unit. The pressure sensor and its housing are integrated within the pump housing, eliminating the need for separate level probes and their associated cables and interfaces. This merging reduces overall device complexity while maintaining reliable level detection functionality through the pressure sensor that measures liquid level via pressure differential.
Solution Approach 2:
The electric immersion pump is designed to perform multiple functions: pumping liquid and detecting liquid level. The pressure sensor serves dual purposes by both monitoring level and providing data to the control unit for pump operation control. This multi-functionality eliminates the need for separate dedicated level detection equipment, reducing complexity while ensuring reliable operation.
2Measurement precision
If immersion probes with cables are used, then level measurement is achieved, but space occupation and installation requirements increase
Solution Approach 1:
The level detection functionality is merged into the pump housing, eliminating the need for separate probe assemblies with cables extending to external interfaces. The pressure sensor is housed within the pump housing, and all processing is done by the pump's control unit, significantly reducing the space required for level detection components and their connections.
Solution Approach 2:
The patent extracts the level detection function from separate external probes and integrates it directly into the pump unit. By taking out the need for external cables and separate probe housings, the solution reduces space occupation while maintaining precise level measurement capabilities through the pressure sensor and control unit integration.
3Ease of operation
If separate power supplies are used for pump and probe, then independent operation is enabled, but installation complexity and cost increase
Solution Approach 1:
The control unit of the electric immersion pump is designed to perform multiple functions including both pump control and level detection processing. The pressure sensor connects directly to this control unit, which handles both power management for the pump motor and data processing from the level sensor. This merging of control functions into a single unit eliminates the need for separate power supplies and control systems, reducing complexity while maintaining ease of operation through unified control.
