Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water taps often lack sufficient pressure for effective cleaning, and using cleaning aids or manual cleaning poses risks and accessibility issues, especially with sharp objects.
Innovation Solution
A jet-forming attachment with a base body that increases water pressure by reducing the outlet cross-sectional area, allowing for targeted and precise cleaning with a high-pressure water jet, and is easily mountable on a water tap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If the outlet cross-sectional area is reduced to increase water pressure, then cleaning effectiveness and safety are improved, but water flow rate is reduced
Solution Approach 1:
The patent changes the geometric parameter of the outlet cross-sectional area to transform the water flow characteristics. By reducing the outlet area relative to the inlet area, the water pressure increases while the absolute water consumption decreases, achieving effective cleaning with less water.
2Measurement precision
If a nozzle with small outlet area is used to increase pressure, then cleaning precision is improved, but device complexity increases
Solution Approach 1:
The patent uses an elastic base body that can be easily manufactured and mounted. The elastic material allows for simple integration of the nozzle structure without complex assembly requirements, maintaining low device complexity while achieving precise water jet delivery.
Solution Approach 2:
The elastic base body automatically seals against the water tap outlet through elastic restoring forces, eliminating the need for separate sealing components or complex mounting mechanisms. The device self-adjusts to maintain the sealing connection.
3Ease of operation
If an elastic base body is used for easy mounting, then ease of operation is improved, but structural stability deteriorates
Solution Approach 1:
The patent combines elastic material properties with an integrated nozzle structure to create a composite functional element. The elastic base body provides mounting flexibility and sealing, while the integrated nozzle geometry ensures structural stability and proper water flow control.
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 provides enhanced cleaning capabilities for objects like razor blades and fingernails with reduced water consumption and improved safety, ensuring a stable and secure fit on the tap.
Implementation Method 1
a base body (6) of the jet-forming attachment has a water outlet nozzle opening (12) with an outlet cross-sectional area (AD) which 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 output from the jet-forming attachment (5) is increased.
Implementation Method 2
By virtue of the fact that the base body has an elastic material, it can be easily attached to the water tap. In particular, the base body is held reliably on the water tap, in particular by reason of the elastic restoring forces.
