Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If liquid soap is supplied manually through storage compartments under the countertop, then space utilization is maintained, but cleaning staff must perform frequent manual inspections and replenishment, reducing working efficiency
Solution Approach 1:
The liquid soap storage system automatically replenishes itself through differential hydrostatic pressure. When the liquid soap level in the storage compartment drops, the system automatically draws more soap from the supply tank without requiring manual intervention, thereby eliminating the need for frequent inspections and replenishment by cleaning staff
Solution Approach 2:
The system incorporates a liquid level sensor that continuously monitors the liquid soap level in the storage compartment. When the level drops below a predetermined threshold, the sensor triggers an automatic replenishment signal, creating a feedback loop that maintains optimal soap levels without manual intervention
2Reliability
If multiple pumps are used to deliver liquid soap from storage compartments to dispensers, then soap supply capability is ensured, but device complexity and maintenance costs increase
Solution Approach 1:
The invention extracts and eliminates the complex pump system from the liquid soap delivery mechanism. Instead of using multiple pumps to force liquid soap through piping, the system relies on natural differential hydrostatic pressure generated by the height difference between the supply tank and storage compartment, thereby simplifying the device structure while maintaining reliable soap supply
Solution Approach 2:
The system utilizes hydraulic principles by employing differential hydrostatic pressure to drive liquid soap flow. The pressure difference created by the height difference between the supply tank and storage compartment naturally propels the liquid soap without mechanical pumps, reducing device complexity
3Area of stationary object
If liquid soap is stored in compartments under the countertop, then space utilization is optimized, but the liquid soap level cannot be perceived from the outside, requiring manual inspection
Solution Approach 1:
The system uses color-changing indicators to communicate the liquid soap level status. When the liquid soap level drops below the predetermined threshold, the liquid level sensor triggers a color change in the indicator (e.g., from green to red), providing clear visual information about the soap level without requiring manual inspection or compromising space utilization
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces maintenance complexity and costs, enhances soap supply efficiency, and provides a visual alert for necessary replenishments, ensuring continuous soap availability without manual intervention.
Implementation Method 1
the height of the liquid level detection unit is higher than that of each of the liquid soap tanks, such that a differential hydrostatic pressure is formed by the liquid soap inside the liquid soap filling tank and that inside each of the liquid soap tanks, whereby the liquid soap is filled into each of the liquid soap tanks automatically from the liquid soap filling tank through the differential hydrostatic pressure

AI summary
An automatic liquid soap supplying system is provided with a plurality of soap dispensing main bodies for discharging a liquid soap, a plurality of soap dispensing components to be respectively connected to the soap dispensing main bodies, a liquid soap filling tank connected to each soap dispensing component, a mounting component provided with a photo display area of necessity for supplying liquid soap, as well as a control unit. In this case, a differential hydrostatic pressure is formed between the liquid soap filling tank and the soap dispensing component, whereby the liquid soap is filled into the soap dispensing component automatically from the liquid soap filling tank through the differential hydrostatic pressure. Moreover, the photo display area of necessity for supplying liquid soap is used to recognize whether supplement of soap is required, and air remained due to the supplement of soap is discharged via a exhaust valve.
