≺ Preamble≻
Plastic benches are no stranger to everyone, almost every family has them, but have you noticed?
In the middle of many plastic benches, there will be a small circular hole, which makes people feel inexplicable, is the round hole in the middle of the plastic bench to facilitate farting?
≺ The "anti-sky design" of plastic benches ≻
said that it was "convenient to fart" and "breathable", but in fact, it was just ridiculed by netizens, how can adults have so many farts to put out.
Even if you take 10,000 steps back, it's really to evacuate this fart, and there's no need to dig a hole in the bench, right? The reason why plastic sheets and the like are designed this way is actually very knowledgeable.
The plastic bench has a low cost, every household can afford it, and it is easy to take, and the most important thing is that it can be stacked and placed at home and does not take up space, it is for this reason that it is loved by many families, and the purchase rate and use rate are very high.
However, success is also Xiao He, defeat is also Xiao He, and its convenience has become its shortcoming.
Because many families will stack plastic benches together when they are not in use, if there is no hole in the middle, then the next time they are used, there will be a situation where the benches are very tightly sucked and completely inseparable.
This is because the plastic is stacked over a long period of time to form a closed layer of air, and if there is a small hole in the middle, on the one hand, the user has a place to exert force when separating the stool, and on the other hand, it can also make them more breathable.
In addition to making it easy to separate the bench, the small hole in the middle is actually to save costs.
The plastic bench is different from other commodities, it does not require a lot of manual or manual work, it is the result of the unified production of the factory assembly line, and there must be a fixed mold on the assembly line, and the small hole in the middle of the plastic bench can just be used for demoulding.
This design can make the cost of the mold lower, but also reduce the amount of plastic, each bench looks like a small piece less, but can not stand a large amount, if the production of hundreds of plastic benches, each bench has a hole in the middle, this will not be saved?
It is said that the wisdom of working people is unlimited, and the third "scientific" point is the convenience of transportation.
With mass-produced goods, it is natural that there will be sales and shipping problems.
When the seller sells the plastic bench to all parts of the country, many transporters and ordinary people have realized a good way to carry the plastic bench, they find a long rope, pass through the hole of the plastic bench, and then tie a knot, a stack of benches can be easily transported, and it will not be messed up.
From a design point of view, a hole in the middle of the plastic bench is also designed for the stability of the overall structure.
Because plastic is a material with good ductility, if the bearing object is heavier, sometimes it will become very soft, the four legs of the bench are crumbling, and there is a possibility of bending at any time, and the hollow design can just make up for this shortcoming, and the weight is dispersed to make the plastic bench stronger.
Some parents are surprised and find a fresh way to use plastic benches – to correct their children's sitting posture.
The average plastic bench has no backrest and is a square seat, so how can this correct the sitting posture?
In order to prevent children from sitting crookedly when doing homework, and in order to protect the spine from childhood, some parents are full of tricks to find a long stick to insert into the small hole of the plastic bench, and put the other end in the child's clothes.
In this way, a straight line can be formed, and sitting up straight will naturally not appear hunched over!
In fact, in addition to a hole in the plastic bench, many things we use in life will have "small holes".
They may seem inconspicuous and even a little frivolous, but they are actually very useful.
≺ Holes in items are ≻ useful
When many people use a tape measure, they will find that there is a small hole at the end of it, and the position of this small hole is very awkward, and many people do not use it when they usually measure, so they will think that it is a chicken rib design.
In fact, this little hole is not a chicken rib, but everyone will not use it.
The small hole at the end of the tape measure seems to be useless when measuring, but if you decorate your home, this small hole can be said to make a great difference.
That small hole can just be stuck in the screw, stabilize the nail and tape measure, even if you are the only one when measuring, you are not afraid of no helper, and one person can do the decoration data properly.
In addition to the tape measure, small holes can sometimes be seen in the design of clothing, shoes and hats.
In fact, some small holes are also "just needed", and they do not only play a decorative role.
For example, some canvas shoes will have a few more small holes on the side, some people will think that this is a breathable or decorative need, but in fact, the function of this small hole is to be used with laces.
By inserting the laces, you can tighten the shoes even if they are a little big, so you don't have to worry about stumbling.
In the kitchen, some kitchen utensils can also find a lot of holes, such as the handle of the cooker will have a hole, many people think it is useless, but its utility is more.
When the pot is not in use, the hole in the handle allows it to hang up without taking up space, and if it is in use, the hole can also be used to put a spoon or spatula, so you don't have to hold a separate plate to place them.
In addition to being at home, there are also some inconspicuous well-off holes on the plane, and many people think that the plane is in flight safety considerations, and the cabin should be a confined space, but it is not.
On the one hand, these holes can balance the air pressure in the cabin, and on the other hand, it can also ensure that the aircraft glass will not atomize with the increase of flight altitude, affecting the journey experience.
≺ Conclusion ≻
Some tricks are everywhere in life, and sometimes you think it's a weird design, maybe there's a better way behind it, but many people don't know it.
