In life, we often express "incomprehension" of some designs, because in the process of use, instead of experiencing "convenience", we may also feel that "there are defects and need to be improved".
As everyone knows, these seemingly stupid designs are actually extremely subtle and have their own "special design significance".
For example, the 10 shared in this issue, forgive me, I was ignorant before.
1. The handrail of the escalator is faster than the rung
Every time I go up the escalator, I can clearly feel that the handrail runs faster than the steps, and I once thought that the elevator synchronization was not good.
I also secretly thought in my heart: An ordinary person can feel that these professional people have such a poor standard?
Later, when I learned about the purpose of the design, I realized that I was ignorant!
This is actually a safety design that takes into account the physiological structure of the arm, if the handrail is faster than the staircase, then the body will lean forward, and the arm can be retracted at any time to adjust the body posture.
However, if the armrest is lagging behind, the joints will become locked, and if the hand cannot be released in time, it may cause the person to fall backwards.
GB 16899-2011 5.6.1 stipulates that the allowable error range between the running speed of the handrail and the speed of the ladder is 0%~+2%.
The running speed of the elevator handrail must be faster than the rung, otherwise it is unqualified.
2. The ID card of the railway station ticket gate should be placed obliquely
In the past, when I took the train, the ticket inspection and ID card were directly placed on the machine.
I don't know when it started.,It's turned into a slanted mouth.,If you don't use your hand to hold it.,You'll have to fall.,I can't help but complain.,This wave of upgrades is terrible!
As everyone knows, this seemingly anti-human stupid design is actually shrewd.
First, the oblique mouth needs to be held by hand, which can save the time for putting documents and tickets to pick up, and each person can save an action, which can greatly shorten the time of entering the station to check in;
Second, it can prevent some people from being careless and forgetting to take the card after checking the ticket. (According to the staff, this is not a rare case, and each class can pick up several ID cards)
Also, the reminder landmarks when waiting for the train are the same, people who don't often take the high-speed rail are confused, there are so many carriages marked in the same place, and they can't understand it, so it's better not to mark it!
In fact, it's not that people are confused, it's that you won't look at it, and there will be clear color indications on the train number signs.
Display the yellow landmark, when you get to the car, you can look at the yellow landmark, you can accurately card the waiting car.
3. Conical disposable paper cups in public places
In many public places, there are such conical disposable paper cups.
I didn't understand that the water cup was designed like this, and it couldn't stand, was it to save paper?
Later, after knowing the real original intention of the design, I realized that my vision was shallow.
Saving paper is just a very small starting point on the basis of not being used, and more importantly, the cone cannot stand, so that the used water cup will be found and thrown into the trash can, instead of "standing" casually.
Moreover, most public places are just temporary thirst quenching sip, the amount is not large, and the cone cup body reduces the capacity, which is also to prevent wasting water.
4. Notch of the thread at the mouth of the beverage bottle
I don't know if you have noticed that the threads of many beverage bottles are missing, especially carbonated drinks.
I used to be stupid, I thought it was decoration, but then I thought I was smart, and I understood it as a small mark for bottles of different drinks to prevent confusion, and said that the shape of the bottle is to distinguish, why is it so good?
When I learned about the designer's intentions, I realized that people have their own subtleties.
The missing thread is to allow the gas in the bottle to be released slowly during the twisting process, so as to avoid the gas in the bottle emitting the cap at the last moment of unscrewing.
Speaking of which, it reminds me that some restaurants have a detailed service, they will clip the straw into the pull ring, at first I said I didn't understand, and it didn't look very beautiful.
Later, I learned that the pipe clamp on the pull ring, without rolling off, can also hold up a little pull ring, no need to pick up a long time, this service is simply too detailed.
5. A bulging ball on an escalator
Every time I get on and off the elevator, I will be attracted by the raised ball next to it, why design it with a small ball, for decoration? It doesn't seem to look good, and it even looks ugly.
After learning the designer's motives, I realized that the elevator can still be a part of play!
Some playful children use the elevator to unlock the slide function, and this raised ball is simply an anti-Jackie Chan device;
It can also prevent some people from putting their luggage on it and losing control, sliding down at high speed and hitting people;
Of course, some people have said that glass balls can reflect the light to see the back, anti-pickpockets, this point, there may be, but it is not prominent, after all, it is not a mirror, it is not so clear.
6. Built-in drawer handles
I bought a bedside table without a handle, and I couldn't open the drawer for a long time, and I asked the customer service to know that the handle was actually installed inside, and I had to remove it and install it outside, which was really not troublesome enough!
After complaining, I realized that although this step seems stupid, it is actually a very smart step in transportation.
The handle installed in the drawer does not have to worry about being lost during transportation, and it can also prevent the protruding handle from bumping during transportation and avoid unnecessary damage.
Good guys, in addition to a little bit of customer trouble, the rest are benefits, but after knowing the purpose of the design, I can understand, after all, it is more important than a little trouble, and the things received are in good condition.
7. A short partition between two urinals
In a more advanced place, there will be a short partition between the two urinals in the men's toilet, and I complained to my friends before: such a short partition does not seem to be able to block privacy, what is the use of it?
As everyone knows, it is such a seemingly useless design that can promote civilization.
Because it is designed like this, everyone will unconsciously take a step forward, subtly improve the cleanliness of the public hygiene, and also prevent occasional mistakes from harming others.
8. Rice ball seaweed in plastic paper
Occasionally, if you don't have time to eat breakfast, you will buy a rice ball at the convenience store downstairs to deal with it, but the packaging design of this rice ball is too stupid!
The seaweed is separated from the rice ball by a layer of plastic paper, and when you eat it, you have to take a bite of the rice and take a bite of the seaweed, which really means that I don't understand.
Later, I learned that it was not that others were stupid, but that I didn't know how to eat it.
The correct way to eat should be as shown below, first tear the unsealing line of the middle line, and then pull out the packaging on both sides, and then put it on.
The purpose of this is also to ensure the taste to the greatest extent, and the seaweed is crispy at any time, rather than softening after a long contact with rice.
9. The virtual password of the password lock
In the past, I once thought that the virtual password of the combination lock was the most useless design, because the person who had to prevent it from taking it home would not take it home, and I had to lose a longer string of numbers containing the password every day, which was not enough to waste time.
But when I see that there are cases of smart locks leaving fingerprints that are deciphered on the Internet, I still feel that it is very necessary to have an extra layer of security.
With a virtual password, even if someone is nearby, there is no need to cover it, as long as you add some numbers before and after the correct password, you can open it, which can hide the real password and increase the difficulty of others to remember.
Also, even if you enter the wrong password, all the previous mistakes will be treated as a void, and you can enter the correct one again, without re-entering.
Of course, even if there are traces on the lock, there are every number, and if you want to decipher, there is no way!
10. Placement of supermarkets
Every time I go to the supermarket, I can notice the small snacks hanging around the aisle pusher, and I think that it is a good way to use snacks to cover the clutter in the pile.
It's just not wise enough, once it is placed in a place where customers bend down to get it, they have to accept the possibility of not buying unless necessary, which may also affect sales.
I took my little nephew to the supermarket, and I realized that it made sense to place it like this, but the audience was not me.
The height of the child is just about the same as the hanging strip of the pile, that is to say, the area of our adult chicken ribs is just the visual gold area of the child, so I will say why my little nephew can't walk in front of each pile.
There is also the shelf placement in front of the cash register, which is just as exquisite.
The upper shelves are filled with chewing gum that adults can easily reach, and below are the loots, toys, and chocolates that children like, so that children can pick out what they want while waiting for the checkout.
Well, I thought people were stupid, but I didn't know that I was "calculated", and I was ignorant before forgiveness.
