你有没有注意过衬衫后面有个小环?挂锁底部有个孔?这些有什么用意呢?还有为什么红酒瓶底有凹槽,圆珠笔尾部有小洞?书包上为什么有个“猪鼻子”?这些很容易被忽略的设计其实都有自己的大用途,一起来了解一下吧。
You may have seen some of these details and wondered what they were for - the tiny holes in a plane window for instance.
日常生活中你可能会注意到一些小细节并对它们的用途困惑不已——例如飞机窗户上的小洞。
Others you may not have noticed at all - like the tiny hole on the base of a padlock.
还有些细节你压根就没发现——例如挂锁底下的小洞。
But all of them have important functions, some potentially life-saving.
但是这些小细节都有至关重要的作用,有些可能还可以救命。
The small hole at the end of biro pen, for example, is there in case a child accidentally swallows it, to provide an air hole so they can still breathe with it lodged in the throat; while the hole in a plane window is to prevent it from imploding should one of the three panes break.
例如,圆珠笔尾部的小洞就是为了防止儿童不慎吞入窒息。当圆珠笔盖卡在喉咙的时候,儿童可以通过这个小小的透气孔来呼吸。而飞机窗户上小洞的用途在于,当飞机上三个窗格中的一个发生破裂时,它可以防止该窗户从内部爆裂。
