Why is not it possible to solve the "pee bouncing problem" of the toilet?

ByAkepon

Urine bounces back at the time of urination, soiled the floor of the toilet, there are many people who have trouble with partners or badly bouncing off their own clothes. In order to solve this problem, there is a method called "Improve the toilet itself" besides "Improve the method of urination", but the urinal which does not rebound still is not popular, the problem remains lying is. Why is there still a toilet bouncing problem in modern technology where technology is developed,PriceonomicsSurveyed independently, the surprising facts have been revealed.

Why Can not We Build a Splash-Proof Toilet?

Brigham Young University· According to a study by four physicists belonging to the laboratory at the splash laboratory, when there is no obstruction, when urination of a man, the urine bounced off from the toilet blows to the point about 1.5 m away from himself about. In other words, when two or more men are facing the toilet beside, the urine of the next men is scattered to their clothes with a high probability. Professor Tadd Trascott who carried out the research is doing various experiments to measure the accurate flight distance when urine bounces, but according to Professor Truscott, the reason why the urine splashes is that of urinating person and urinal It is said to be in both.

Prof. Trascott and colleagues created a "urination simulator" that pumps water from the nozzle and observed how it splashes when water hits the toilet with a high-speed camera. As a result, several things turned out.

First of all, it means "little scattering when the distance from the toilet bowl is short". Liquid flows through the air, and when it strikes an object it becomes a droplet and it scatters wider than the place where the original "flow" was. This phenomenon is a technical term "Rayleigh-Taylor instabilityIt is explained as. At this time, it was observed that the farther the farther away the farther the distance from the place where the liquid is released the farther the droplet scatters.

In addition, the research team confirmed that "the scattering is less as the spot emitting liquid is closer to the toilet than it is parallel." When liquid was applied to the toilet from an angle of 90 degrees, the rebound was terrible, but from the top, it seems that there was little rebound and it was difficult for the urine to get a drop.


The research published by Professor Trascott et al. Got a lot of attention as compared with the average hydrodynamics study and it was not until the BBC was interviewed, why are these research results awaited Cow. In other words, why can not we solve the problem by improving the design of the toilet bowl?

Priceonomics is a leading German-based bathroom fixtureDurabitWhen asking the designer of the company, I got an unexpected response that "the problem is already for the past". Durabit made a test and it seems that the rebound in Durabit's toilet seems to have resulted in "three drops of maximum 2 mm are scattered within 20 cm radius", and the designer sees "urine scattering problem" as It does not already exist, and now it is shifting to solving other problems such as a method of saving water. In addition, Durabit's designer said that he mentioned "a method of drawing one flame in a toilet and dropping droplets by 70% just by aiming at that urination."

Next, Priceonomics contacted Mr. Tim Schroeder, representative of Durabit · America, and again the answer was "There is no rebound in the current toilet". According to Priceonomics, Mr. Schroeder is not ignoring the existence of problems as executives of corporations often do, but as he seems to be confused about the question, "Mr. Schroder is a part of the toilet that is putting water in the toilet 20 years ago After improving, such complaints have not come. " In response to the toilet bouncing problem, "I am not interested but I have not heard of such feedback." Durabit's designer - says "Places to draw fly", that is, sweet spot certainly exists, but Mr. Schroder's opinion that many of the bounces are caused by human error. "I sometimes dress my clothes and the surroundings while washing my hands at the sink, but I am careful, so I will not get dirty," Schroder says.


As a matter of fact, in general households, the couple is debating issues like crowds everyday like general everyday, but as Priceonomics conducts the survey, "In a company that is making toilet bowls, it is said that such a problem has not already existed" There is a mystery rising.

Priceonomics introduced the Japanese toilet with the function to warm the toilet seat and bidet button etc in 2012 as "better than any other toilet in the millionaire 's house in the United States". However, despite the fact that you do not need to use paper with the bidet function, many Americans are still using toilet paper.

Steve Cher, president of startup trying to sell Japanese toilets in the US, explains that "Americans have resistance to talking about bathroom problems" is a major obstacle. When trying to explain the benefits of bidet, people are commenting as "disgusting" or giggling to laugh.

According to Professor Harvey Morlock of New York University, it is said that toilets are caught as "taboo", so feedback between customers and companies is not well done. In the case of the iPhone, we can not speak freely where toilet is where feedback is made as to why this is this and how it can not be improved in this way, so product improvement can not be done well That's it.

When Priceonomics told Prof. Morlock about the mystery of the toilet bouncing problem, it turned out that Professor Morlock had similar experiences. As Mr. Morlock's view is that the toilet problem is not picked up at the company's management team meeting, regarding the toilet, "What really happened can not be incorporated into these designs".

Even if media develops and pornography and others come around, we are ignorant about toilet. Anonymous bulletin boardRedditThen, one male interpreted mistakenly "raising a toilet seat at the time of a toilet" at the time of a child, confessed that he was evacuating while lifting his toilet all the time in his life so he became a legend But there are also comments on it that "When my baby defecates in the office, I took the toilet paper with his hand wrapped around the toilet paper so that it would not sound and dropped it in the water" It seems there was. No one publicly talks like this, so I can not ascertain if the story written on the bulletin board is true. I can understand how the toilet problem is taboo by what kind of reaction the opponent asked "Do you want to peep in the shower?"

The rebounding problem is difficult to be surfaced by being hidden behind the shadow of toilet circumstances being viewed as a taboo, but not all toilet makers are not paying attention to the bouncing problem.KOHLER"We recognize that rebounding is a major problem in today's toilet circumstances," and claims that "productive rebound is practically lessened" at the time of product announcement.

However, in order to solve the bouncing problem in earnest, it is necessary to eliminate itself "to look at the toilet taboo" itself. Priceonomics concludes that we need to complain about the toilet, as we complain about and complain about the iPhone or Starbucks cup.
