Product name: Noise-free braking

随着人类生活的丰富，噪音污染也成为影响人们生活质量的问题之一。特别是在以电动车、自行车为出行主工具的国家，拥挤的街道上充斥着各种噪杂的刹车声。随着扎皮的磨损老化，不仅给驾驶者带来安全隐患也给附近的居民行人带来大分贝的噪音。因此我们利用磁铁同极相斥原理来达到减速刹车的目的,有效的解决日常生活中的这个问题。

With the enrichment of human’s life, noise pollution has also become one of the problems affecting people’s life quality. Especially in countries where electric vehicles and bicycles are main traveling tools, the crowding street are blooming with sundry noises of braking. With the aging and wear and tears of the brake rubbers, not only security risks are imposed to the drivers, heavy noise decibels are also brought about to the nearby residents and pedestrians. Therefore, we utilize the principle that the like poles repel each other to achieve the purpose of braking deceleration to effectively solve this problem of daily life.
