Sanitary Insert Unit Bypass Nozzle for High-Force Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low water pressure in arid countries and mandatory low volume flow in other countries make it difficult to effectively clean articles with existing sanitary insert units, as they fail to produce a powerful cleaning jet with limited water supply.
Innovation Solution
The sanitary insert unit features a bypass duct with a narrowing clear duct cross section to create an accelerated liquid jet, combined with a flow rate regulator and lattice or mesh structure to generate a powerful cleaning jet, while maintaining low water consumption and ensuring effective cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If water flow is reduced to meet low consumption requirements, then water saving is improved, but cleaning effectiveness deteriorates
Solution Approach 1:
The water flow is segmented into two separate paths: a main liquid path that delivers aerated soft jet for general washing, and a bypass duct that delivers concentrated high-velocity jet for cleaning. This segmentation allows each path to serve its specific function with optimized flow characteristics, enabling effective cleaning with minimal water consumption.
Solution Approach 2:
The bypass duct functions as a hydraulic nozzle that converts pressure energy into kinetic energy, creating a high-velocity jet. The lattice structure in the main path introduces air into the water flow, creating an aerated soft jet. These hydraulic and pneumatic mechanisms enable different jet characteristics from the same water supply, resolving the contradiction between water saving and cleaning effectiveness.
2Use of energy by moving object
If water pressure is low, then energy consumption is reduced, but jet velocity and cleaning force deteriorate
Solution Approach 1:
The bypass duct changes the velocity parameter of the water flow by constraining it through a narrowing cross-section, converting pressure into velocity. This parameter transformation enables high jet velocity even when supply pressure is low, without requiring additional energy input. The lattice structure similarly transforms the flow regime from dense to aerated, changing the physical parameters of the jet.
