Those "unclear" designs! Netizen: Wrong designer

I don't know if you have such an experience?

In the daily life, I met some seemingly stupid and inconvenient designs, until one day I realized the designer's intentions, and then I suddenly became more cheerful, and then shouted exquisitely.

Slot detection area of automatic ticket dispenser

If you take the train and the high-speed rail frequently, you will find that the automatic ticket machine at the train station places the ID card in a tilted position. If you don't hold your ID card, you will slide down and you will not be able to read the card smoothly.

This design seems inconvenient, but it is not.

Imagine if the place where the card is placed is flat, a person who catches the train hurriedly changed the ticket, and it is likely to drop the ID card. This design makes it necessary to hold the ID card. It seems that the trouble is that many people are sloppy and lose their identity cards.

Handrail differential for escalators

Usually, when you go shopping, you will take the escalator when you go to the subway station. In fact, a friend who is careful may find that the track of the armrest is faster than the pedal. The hand that was placed on the track parallel to the body slowly moves to the front of the body.

Is the master who installed the elevator not set up? Later, when I saw the principle by chance, I suddenly realized it.

Originally, the national standard for escalators was to specify that the handrails were faster than the steps (0 to +2%). This is to prevent the passenger from holding the handrail, because the speed of the handrail is slower than the pedal speed, causing the human body to lean back and an accident occurs.

Annoying serpentine fence

Whether it is to buy tickets or enter the market, every time there are more queues, a row of serpentine guardrails will be launched. Everyone has to detour, and many people are very disgusted with this design.

In fact, this thing that makes people feel uncomfortable really avoids a lot of trouble. Imagine if there is no such serpentine guardrail, will it lead to chaotic crowds and queues?

Bored corners on the highway

Drivers who drive often out of the car may find that there are often some inexplicable corners on high speed. Is it necessary to artificially set up a few corners in the Great Plains of Pingyuan and Mapingchuan? Many people feel that this wastes resources and causes unnecessary trouble for driving.

In fact, this is really deliberately designed. Driving on a straight road for a long time, the driver lacks sensory stimulation, is prone to mental fatigue, and the speed and rapid response ability will be greatly reduced. Sometimes, seeing a straight road will induce a desire to drive.

The purpose of deliberately setting the curve is to make your attention, brain clear, responsive and speed limit, thus reducing the occurrence of car accidents.

Name for the coiled mosquito coil

I believe many people have hurt their brains for this thing. Every time I remove the mosquito scent, I find it difficult to remove it.

In fact, there are many hidden benefits behind this difficult to dismantle. The first is that it is not easy to break. If it is made of a long one, it is not easy to pack and collect, and it is easy to break.

Secondly, the coiled mosquito coils also save space. It does not require too much storage space while satisfying the length. And compared to other types of mosquito coils, disc-type mosquito coils can control the range of combustion within a small circumference, enhancing safety.

Round hole in a plastic stool

There are always round holes in the plastic stools we often sit on. I believe many people are curious about what this small hole is doing?

In fact, this round hole is used to prevent air from being isolated. Several such stools are picked up. If there is no round hole, a confined space will be formed. Even if it is a strong man, it is difficult to separate. Moreover, the small hole is preferably round, and if it is a sharp hole, the force is easily broken.

Soda bottle mouth spiral has a gap

那些“不明觉厉”的设计!网友:错怪设计师了

Many people have not noticed that there is a gap in the spiral of the bottle mouth of the carbonated beverage, which is not connected. There is also a gap in the corresponding position on the bottle cap. Why is there such a design?

Those "unclear" designs! Netizen: Wrong designer

It turns out that a certain amount of carbon dioxide is injected into the carbonated beverage. The effect of these gaps is that the gas in the bottle is quickly leaked through the gap during the opening process, otherwise the residual gas pressure is reached at the last moment of unscrewing. The cap will be fired like a cannonball.

Difficult to open pill bottle

Some medicine bottle caps need to be pressed down to be unscrewed, and people who don't know are less likely to open the bottle for the first time. Why do you have to do this to design a complicated bottle opening method?

This seemingly counter-intuitive, inconvenient design, the main purpose is to prevent children from eating drugs. When the average person sees the bottle cap and can't open it, he usually tries to open it in the opposite direction, or try to lift it up, but rarely thinks about pressing down.

Children generally do not understand the above text, so the probability of opening a bottle to take a pill is greatly reduced by curiosity, so as to achieve safe drug storage.

Air gap in the bathroom partition

Everyone has been to the public toilets and knows that there is a relatively high gap under the bathroom partition. So why do you want to leave this gap?

In fact, there are three reasons: one is to prevent accidents from being discovered after the occurrence of emergencies; the second is to prevent water accumulation, and it is convenient for cleaning personnel to clean; the third is to facilitate each other to hand over paper towels.

Groove at the end of the toothpick

Everyone often sees a toothpick with a pointed tip, and a flat one is also engraved with several slots. Have you ever thought about why the flat head has to spend a few hours to engrave? It seems that it is time-consuming and easy to break, and it is a bit of a superfluous addition.

In fact, this is to let us cut off the end of the toothpick and use it as a toothpick holder to prevent the front end of the toothpick from being contaminated and can be used repeatedly.
