Venturi Reservoir Evacuation for Dry Soap Transfer in Shower Heads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shower head technologies lack a reliable and efficient method for evacuating liquid reservoirs to dryness and conserving water, failing to accommodate multiple types of liquids and ensuring complete use of soap or liquid contents during showering processes.
Innovation Solution
A liquid reservoir evacuation apparatus featuring a venturi valve with a smaller inlet and larger outlet, an air intake system, and multiple on/off valves to manage liquid flow and air intake, allowing for the transfer of liquids between reservoirs and conservation of water, including the use of a transfer device with a reservoir extension for complete evacuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a conventional shower head is used, then water flows continuously, but liquid reservoir cannot be evacuated to dryness and water is wasted
Solution Approach 1:
The patent employs a venturi valve that utilizes fluid dynamics and pressure differentials to create suction. When water flows through the venturi valve, it creates a low-pressure zone that draws liquid from the reservoir through a transfer device, enabling evacuation without mechanical pumps or manual intervention.
Solution Approach 2:
The patent implements a two-reservoir system where the first reservoir receives and stores liquid, and the second reservoir collects evacuated liquid. This allows complete utilization of the liquid supply by transferring it from the first reservoir to the second reservoir, ensuring no liquid is wasted.
2Productivity
If hand-held liquid application is used, then some liquid can be applied, but complete use of liquid contents cannot be ensured
Solution Approach 1:
The system performs self-evacuation of the liquid reservoir through the venturi-induced suction mechanism. The liquid is automatically drawn from the first reservoir through the transfer device and deposited into the second reservoir without requiring manual pumping, pouring, or complex user operations.
3Adaptability or versatility
If multiple liquid types are applied separately, then different emollients can be applied, but current technology does not provide separate application capability
Solution Approach 1:
The patent divides the liquid application system into separate functional components: a first reservoir for receiving liquid, a venturi valve for evacuation, a transfer device for movement, and a second reservoir for collection. This segmentation allows the system to handle multiple liquid types by simply changing the liquid source while maintaining the same evacuation and transfer mechanism.

Function Achieved in This Case
Enables efficient evacuation of liquid reservoirs to dryness, conserves water by reusing previously wasted water, and allows for the separate application of multiple types of liquids during showering, improving the flexibility and effectiveness of liquid dispensing systems.
Implementation Method 1
a venturi valve with an inlet with a diameter and an outlet with a diameter where the inlet has a smaller diameter than the diameter of the outlet
