Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing low-flow water devices for showers struggle to maintain high water pressure without increasing water consumption, necessitating an improved vacuum venturi apparatus that uses existing showerheads and incorporates no moving parts.
Innovation Solution
A vacuum venturi apparatus with a plug featuring multiple openings of varying diameters and flared sections, designed to fit within a shower pipe, creating a powerful venturi effect by optimizing fluid flow and vacuum pressure through a combination of diameters and angled flared sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If existing low-flow water devices are used, then water consumption is reduced, but water pressure perceived by the user decreases
Solution Approach 1:
The patent introduces a vacuum venturi apparatus as an intermediary device installed between the water source and showerhead. This apparatus uses a venturi mechanism with specifically dimensioned openings (first opening with diameter d1, second opening with diameter d2, third opening with diameter d3) to create vacuum pressure that draws air into the water stream, increasing momentum and perceived pressure without increasing water consumption.
Solution Approach 2:
The patent changes the physical parameters of fluid flow by using a venturi effect with specific diameter ratios. The first opening has diameter d1, the second opening has diameter d2 where d2 < d1, and the third opening has diameter d3 where d3 < d2. This parameter progression creates the necessary pressure differential to generate vacuum and enhance water flow characteristics without increasing consumption.
2Power
If vacuum venturi apparatus with multiple openings is used, then venturi pressure and efficiency increase, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated plug component. The plug contains all three openings (first, second, and third) with specific diameter relationships (d1, d2, d3) and incorporates flared sections, merging the venturi effect generation, vacuum creation, and flow regulation functions into one piece that installs in the existing shower pipe without requiring multiple separate components.
Solution Approach 2:
The plug serves multiple functions simultaneously: it creates the venturi effect through its opening configuration, generates vacuum pressure, regulates water flow, and interfaces with existing shower pipe and showerhead components. This multi-functionality reduces the need for additional specialized components, offsetting the complexity introduced by the multiple openings.

AI summary
A vacuum venturi apparatus includes a plug with a first opening, a second opening and a third opening. The first opening is located in the plug so as to receive fluid from a source of fluid and the first opening has a single uniform diameter. The second opening in the plug is connected to the first opening and the second opening has a first diameter and a second diameter and the first diameter is larger than the second diameter and the second diameter is the same as the single uniform diameter of the first opening. Further, the second opening second diameter is connected to the first opening. The third opening is located in the plug and is open to the atmosphere. The third opening has a first diameter and a second diameter and the first diameter is larger than the second diameter and the second diameter is smaller than the single uniform diameter of the first opening, Further, the third opening second diameter is connected to the first opening. Further, the third opening may or may not have an attachment for the purpose of directing a vacuum line to a reservoir.
