Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing faucet water pressure is often insufficient for effective cleaning, and conventional cleaning aids like brushes limit access and pose safety risks during cleaning of sharp objects.
Innovation Solution
A jet-shaping attachment with a base body having a smaller outlet cross-sectional area than the inlet, increasing water pressure and enabling targeted cleaning with a pinpoint water jet, which can be easily attached to a faucet using an elastic material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If water is discharged from a standard faucet, then water flow is sufficient, but water pressure is insufficient for effective cleaning
Solution Approach 1:
The patent changes the geometric parameters of the water outlet by providing a nozzle opening with a smaller cross-sectional area than the inlet opening. This parameter change transforms the water flow characteristics, increasing pressure while maintaining flow continuity, thereby resolving the contradiction between sufficient pressure and effective cleaning.
2Stress or pressure
If a nozzle with smaller outlet area is used, then water pressure increases, but water consumption decreases
Solution Approach 1:
By changing the outlet cross-sectional area parameter to be smaller than the inlet area, the system achieves pressure intensification while simultaneously reducing water consumption. The geometric parameter change creates a focused jet that delivers higher pressure with less water volume.
3Stress or pressure
If a nozzle with smaller outlet area is used, then water pressure increases, but targeted cleaning capability is improved
Solution Approach 1:
The patent applies parameter changes by reducing the outlet cross-sectional area, which simultaneously increases water pressure and improves targeted cleaning capability. The smaller outlet area focuses the water flow into a more concentrated jet, enhancing precision for cleaning intricate or delicate objects.
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
The attachment enhances cleaning efficiency by increasing water pressure, reducing consumption, and allowing safe, precise cleaning of objects like razor blades and jewelry without the need for cumbersome tools.
Implementation Method 1
a base body (6) of the jet-shaping attachment (5) has a water outlet nozzle opening (12) with an outlet cross-sectional area (AD) that is smaller than an inlet cross-sectional area (AE) of a water inlet opening (11) of the base body (6). The pressure with which the water is released from the jet-shaping attachment (5) is increased.
Implementation Method 2
Because the base body is made of an elastic material, it can be easily attached to the faucet. In particular, the base body is securely held to the faucet, particularly due to its elastic restoring forces.
