1 问题发现需求 1、自行车的车锁往往解锁不便，在平 时我们解锁时，往往要弯下腰或者蹲着 解锁，这无疑在我们手上拿着东西的时 候显得麻烦，并且也有些浪费时间。 2、对于老人而言，弯腰不但不便甚至 对身体也有影响。 3、共享单车固然可以站着刷卡解锁或 者如ofo的蓝牙解锁，但是其耐久性能远 不如私人的自行车。 4、防盗性能不好。 Florence is the capital city of the Italian region of Tuscany and of the Metropolitan City of Florence.It is the most populous city in Tuscany.with 383.083 inhabitants(as at 2013).expanding to over 1.520,000 in the metropolitan area

O 现有设计的不足 1、蓝牙，电子这些解锁方式固然方便， 但是如果成本高起来不会让人接受。 2、因为有自动关锁的步骤，若是不加考 虑，关锁时可能直接撞在辐条上，结果 是没锁住或是损害车子甚至两者兼有。 3、整体应该不宜太重，否则影响骑行体 验，骑行会更费力。 Florence is the capital city of the ltalian region of Tuscany and of the Metropolitan City of Florence.It is the most populous city in Tuscany.with 383.083 inhabitants(as at 2013).expanding to over 1.520,000 in the metropolitan area

2 车锁改造的价值和未来展望 1、在车辆较为拥堵的大城市，自 行车有其大显身手的空间，甚至比 一般私家车辆快速。 2、作为一种清洁，廉价的代步工 具，自行车远不到退出历史舞台的 时刻。 3、对于自行车爱好者，自行车更 加自动化令人兴奋。对于弯腰不便 的人而言，人性化的革新令人欣慰。 4、骑行自行车不失为现代快节奏 生活锻炼身体的一种好办法。 Florence is the capital city of the Italian region of Tuscany and of the Metropolitan City of Florence.It is the most populous city in Tuscany.with 383.083 inhabitants(as at 2013).expanding to over 1.520,000 in the metropolitan area
