“小豆包”进学堂 铅笔盒里装些啥

2017-09-03 14:45:54   中国青年网

“小豆包”的铅笔盒总是装得满满当当的,铅笔、橡皮、尺子没少装,不过“小豆包”丢三落四,到用的时候总有找不着的,特别是橡皮,明明出门前放了好几块,可一到要用的时候就不知道哪儿去了?有人发明了带橡皮的铅笔,不过铅笔尾巴上的那一丁点儿橡皮,“小豆包”用两下就磨秃了。看看俄罗斯设计师设计的这支铅笔吧,直接将铅笔和橡皮二合一,铅笔的笔杆不再是木头等材质做的,用的直接就是橡皮。写错了想涂改,直接用笔杆擦擦就行了。橡皮做笔杆还有个好处,就是握在手里也比硬邦邦的木头笔杆舒服多了。

不用担心找不着橡皮了,咦,尺子又跑哪儿去了?“小豆包”又有烦恼了!别担心,铅笔盒里要是装着这种铅笔就再也不用找尺子了,而且无论是直线还是曲线,都能一下子就测出长度来,这可不是经常带的直尺能做到的。要用这支铅笔量长度,只要用笔尖沿着要测量的线段描一描,别管线是直的还是曲里拐弯的,铅笔尾部的小显示器上都能一下显示出长度来。看看,边上那个标着毫米、厘米、英寸等单位的小旋钮,想用什么长度单位,测量之前拧一下就行了。

橡皮和尺子的问题解决了,可铅笔盒里那一堆的笔怎么办?明明带了那么多,可一会儿工夫怎么就有好几支不知道放哪儿了?刚进校门的“小豆包”乱拿乱放的毛病,看来不是一下能改过来的。一家伦敦设计工作室的两位设计师为“小豆包”的铅笔上加了个小物件儿——一根小小的橡皮筋。别看就是这么个小改变,一堆的铅笔一下就好收拾多了。不用的铅笔都用这根橡皮筋固定在一起,一堆的铅笔就都不会再“乱跑”了。有了这根橡皮筋,有时候铅笔盒都不用带了。

刚进校门的“小豆包”开始学写字了,每天在田格本里不停地习字,铅笔还真是挺费的,一支笔没写两天就短到没法持握了,于是每个“小豆包”都曾扔过一把一把的铅笔头。设计师想了个好办法,让这些铅笔头能好好地利用。设计师的设计很简单也很巧妙,将每支铅笔的两端一头做成凸出的,一头做成凹进的,凸出的部分和凹进的部分可以互相嵌在一起。当铅笔用到一定时候剩下的长度不好持握时,只要将这个铅笔头接在另一支新的铅笔上就行了,既很实用也很环保。
