Urinal Nozzle Filtration for Scale Inhibition and Easier Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The surface of urinal bowls forms scales and dirt, which are difficult to clean, especially in bends, requiring manual scrubbing with detergents and labor, and can cause odor, bacterial growth, and health issues.
Innovation Solution
A urinal system with a filter element containing a scale-inhibiting agent in the nozzle inlet pipeline, connected to the inlet valve and nozzle, which inhibits scale formation and facilitates easy replacement of the filter element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual scrubbing with detergents is used to remove dirt from the urinal bowl surface, then cleaning effectiveness is improved, but labor cost and cleaning material cost increase
Solution Approach 1:
The system enables self-cleaning by automatically injecting cleaning solution through the nozzle onto the urinal bowl surface, eliminating the need for manual scrubbing. The control unit automatically activates the inlet valve and nozzle based on sensor detection, making the cleaning process autonomous and reducing labor requirements.
Solution Approach 2:
The system uses hydraulic principles by utilizing water pressure from the inlet valve to deliver cleaning solution through the nozzle. The high-velocity water jet mechanically removes dirt and scale from the urinal surface without requiring manual intervention, thereby improving cleaning efficiency while maintaining effectiveness.
2Object-affected harmful factors
If manual cleaning is performed frequently to remove accumulated dirt and scales, then hygiene is improved, but water consumption and cleaning material consumption increase
Solution Approach 1:
The system implements periodic cleaning cycles triggered by sensor detection rather than continuous operation. The control unit activates the inlet valve and nozzle only when dirt accumulation is detected, creating intermittent cleaning actions that maintain hygiene while minimizing water consumption compared to continuous or frequent manual cleaning.
Solution Approach 2:
The system replaces mechanical manual cleaning with an automated hydraulic jet system. The high-velocity water jet from the nozzle mechanically removes dirt and scales more efficiently than manual scrubbing, achieving better hygiene with less water and no cleaning materials.
3Ease of repair
If the nozzle inlet pipeline is designed to be easily disassembled for filter replacement, then maintenance ease is improved, but device structure complexity increases
Solution Approach 1:
The nozzle inlet pipeline is divided into separable sections with standardized connection interfaces. The filter element is positioned in an accessible location that can be independently accessed and replaced without disassembling the entire pipeline, maintaining structural integrity while enabling easy maintenance.
Solution Approach 2:
The filter element is designed as a replaceable, consumable component that can be easily swapped out when depleted or clogged. This disposable approach simplifies maintenance by allowing quick replacement rather than complex cleaning or repair, justifying the slight increase in structural complexity through standardized quick-connect mechanisms.
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 system effectively inhibits scale formation, reduces manual cleaning efforts, and maintains hygiene by using a simple and replaceable filter element design.
Implementation Method 1
A scale-inhibiting agent is contained in the filter element. The compound for inhibiting scale in the filter element inhibits substances in the water entering the nozzle.
