Urinal Water Sprinkling Device for Ammonia Odor Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Urinal apparatuses fail to effectively eliminate odors generated from urine decomposition, as existing deodorization methods are incomplete in sterilizing bacteria and distributing detergent, leading to ammonia gas reaching users due to inadequate flushing and water distribution.
Innovation Solution
A urinal apparatus with a water supplying device and a water sprinkling device that supplies water to the bowl section and sprinkles water droplets between the trap section and the user's nose, timed differently to flush and dissolve ammonia, with adjustable sprinkling sections and droplet sizes to maximize odor suppression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water is supplied to the bowl section for flushing, then urine and foreign matter are removed, but water splashes out of the bowl section and the region not supplied with water becomes a source of odor
Solution Approach 1:
The invention divides the water supply function into two separate devices: a water supplying device for flushing the bowl section and a water sprinkling device for treating specific regions. This segmentation allows each device to perform its function optimally without causing water splashing, while ensuring complete coverage of the bowl section to eliminate odor sources.
Solution Approach 2:
The water sprinkling device operates before the water supplying device to pre-treat the bowl section surface. By sprinkling water droplets in advance, the device prepares the surface to receive the main flush water, preventing water splashing and ensuring that all regions are covered before the high-velocity flush occurs.
2Productivity
If a large amount of water is passed at fast flow velocity to remove foreign matter, then flushing effectiveness is improved, but water splashes out of the bowl section
Solution Approach 1:
The water sprinkling device performs preliminary wetting of the bowl section surface before the main flush. This pre-treatment reduces water splashing by ensuring the surface is already saturated, so the high-velocity flush water does not bounce off dry surfaces and splash outward.
Solution Approach 2:
The water sprinkling device applies water locally to specific regions of the bowl section that would otherwise not be reached by the main flush. This localized pre-treatment ensures complete coverage without requiring the entire bowl section to be subjected to high-velocity water that causes splashing.
3Ease of manufacture
If detergent is supplied together with flush water, then cleaning is improved, but urine remaining in the male urinal is still decomposed by common bacteria to generate ammonia
Solution Approach 1:
The invention separates the cleaning function (detergent supply with flush water) from the deodorization function (water sprinkling). The water sprinkling device operates at different timing to specifically address ammonia generation by ensuring complete water coverage of the bowl section, including regions that would otherwise remain untreated.
Solution Approach 2:
The water sprinkling device operates in conjunction with the flush cycle to provide continuous water treatment. By sprinkling water before and during the flush, the system ensures that detergent and water work together continuously to prevent bacterial decomposition and ammonia generation throughout the entire flushing process.
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 solution efficiently suppresses ammonia and other odors by increasing the water's surface area contact with ammonia, preventing updrafts, and ensuring droplets do not splash or wet users, effectively reducing odor perception and saving water.
Implementation Method 1
The water sprinkling device is configured to sprinkle water droplets to a region inside the bowl section, the region being located between the trap section and position of a nose of a user facing the bowl section
Implementation Method 2
a water supplying device configured to supply water to a bowl section of a urinal
Implementation Method 3
a trap section provided in a lower part of the bowl section and configured so that urine and water flow into the trap section
