1Extent of automation

If a sensor unit with height-adjustable structure is used on the pump housing, then the pump can be automatically controlled according to liquid level, but the height control structure becomes complicated and operational stability deteriorates

Engineering Contradiction:
Improveautomatic water level controlVSAvoidheight control structure
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The pump housing is divided into multiple fixed sensor mounting positions at different heights, allowing the sensor unit to be installed at predetermined locations without requiring complex adjustment mechanisms. This segmentation of the housing into standardized mounting zones simplifies the overall structure while maintaining automatic water level control functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sensor mounting positions are pre-designed and pre-positioned on the pump housing during manufacturing, with each position corresponding to a specific height. This preliminary arrangement eliminates the need for complex field adjustments and ensures operational stability by fixing the sensor at predetermined optimal locations before the pump is deployed.

Inventive Principle:

Solution Approach 1:

Multiple sensor units are provided, each capable of functioning as a complete water level detection system. Any single sensor unit can independently measure water level at its fixed position, and the system can operate with one or multiple sensors depending on the application requirements. This multi-functional design allows flexibility in water level measurement without requiring complex integration or additional adjustment mechanisms.

Inventive Principle:

Solution Approach 2:

The sensor units are designed as simple, cost-effective components that can be easily manufactured and installed at fixed positions. Rather than using expensive, complexly-adjustable sensors, the invention employs straightforward sensing elements mounted at predetermined locations, reducing manufacturing costs while maintaining the capability to measure multiple water levels through the array of fixed-position sensors.
