我发明“多功能门窗”的想法,是一次偶然事件引起的。有一次,我放学回家穿过一条巷子,不小心撞到一家向外开着的窗扇上。当时我很生气,心里想:他们家为什么不安装推拉窗呢?到家后,妈妈见我不高兴,问我为了什么事,我就把头被撞的事情讲了,边说边抱怨这是他们不装推拉窗的缘故。妈妈开导我说:“孩子,做事可要动脑啊!你仔细想一想,推拉窗就没有缺点吗?”对妈妈的话,我半信半疑,难道推拉窗也有毛病吗?我站在窗前,边观察,边思索。终于,我发现推拉窗打开时,最大通风量只有整个窗的一半。这时,我脑子里闪过一个念头,如果把两种类型的窗结合起来, The idea that I invented “multi-function doors and windows” was caused by an accidental event. Once, I went home from school to go through a lane and accidentally bumped into an open window sash. At the time, I was very angry and thought to myself: Why didn’t their families install sliding windows? When they got home, my mother was unhappy when she saw me. I asked what I was doing, and I said something about the head crashed. I said while complaining that they were not. Sliding window for sake. Mother enlightened me and said, “Children, they must use their brains to do things! When you think about it, there are no shortcomings in sashing the window?” I was half doubtful about Mom’s words. Is there anything wrong with the sliding window? I stood by the window and observed , thinking about it. Finally, I found that when the sliding window was opened, the maximum ventilation was only half of the entire window. At this moment, a thought flashed in my mind if we combined the two types of windows.
