After getting over my fear of showering ( ablutophobia ), I now consider urination and how to do it right. The run-of-the-mill toilet is a simple device, easy to handle, and - for the most part - undemanding of electricity (excepting the ones that know when you're done and do the flushing floor polisher for you). When I was little, water tanks were placed high, and the operative action was to pull on a chain to lift the stopper at the bottom of the tank, which in turn would release a cascade of water. Flushing is water plus gravity. This functional design has all but died out. I found a surviving floor polisher specimen behind the basilica of Sveta Gora (Holy Mountain) near Gorica, Slovenia.
In time, the tank was placed just above the toilet. Apparently, there is still enough gravity floor polisher for the job. Then, in some places, the tank disappeared in the wall and sensors tell when it's flushing time. With all this simplicity, what's left for the engineers to mess up? Enter the ecologists. The ecologists want you to use as much water as is sufficient to do the job, but not more than necessary. If there were no variation in the volume of urination or defecation, a standard amount of water would do. But humans vary in size and so do the jobs they have to do. It is beyond us to accurately map the amount of water needed onto the need itself. So what we have is a crude dichotomy floor polisher of "a little water" and "a lot of water."
In the Groningen, NL, boutique hotel, I found no levers to operate the toilet, but two plates on the wall behind. One plate was about 3 by 5 inches and the other was even larger, perhaps 4 by 6 inches. I assumed that pressing the large plate would release more water and would be more wasteful than pressing the small plate. I tested and corroborated this theory, wasting water in the process. So this is how the designers responded floor polisher to the mapping problem: they mapped the size of the fixture onto the size of the effect (amount of water). This solution is reasonable, but it is not perfect. The large plate was easier to hit than the small plate because it was (a) larger, and (b) the first to come into view (and reach) as I rotated to the right. Like most people I am right-handed floor polisher and thus more facile with right-bound motion; also, the toilet paper was mounted on the wall to the right. In other words, the designers wanted to nudge me to press the small plate, but the environment they created-in conjunction with my habits of motion-steered me toward the large plate. Good design avoids such conflict.
As an alternative, designers may want to consider making the control that executes the wasteful option smaller, harder to reach, and requiring greater effort. For example, the high-volume flush could be operated floor polisher by pushing-with effort-a small button located under the low-flow default option.
Men like to pee standing up. That's why the urinal was invented. The urinal also increases the efficiency of (the response to) nature's call for half of humanity, and thereby creates a gender imbalance floor polisher (note the long lines in front of the ladies' room; but that is not the topic of this post). An unintended floor polisher side effect of urinals floor polisher is the mess from imprecise aim. It is facile and pointless to blame the urinators for their carelessness. What would be the consequence of such attribution of responsibility? Classes, tutorials, penalties, floor polisher prizes? It is better to ask if the design can be improved to reduce human error.
Year ago, according to Kim Vicente (" The Human Factor, 2004), floor polisher a Dutch designer had the idea of drawing a small fly in the urinal just above the drain. Brilliance! The urinator instinctively aims to hit and
