小学生获国家专利 厉害了!3D打印鲁班锁

2017-09-15 08:36:40   央广网

一把把精致的鲁班锁,玩起来不仅有趣,还能锻炼思维,更有小学生们制作的鲁班锁获得了国家专利。

今天,记者从北京市朝阳区实验小学获悉,该校毕业生杨家林、邱禾佳、程可欣,在他们小学四年级完成的课堂学习作品——3D打印鲁班锁获得国家知识产权局颁发的外观设计专利证书。

鲁班锁是中国一种古老的儿童益智玩具,相传由春秋末期到战国初期的鲁班发明,它与九连环、华容道、七巧板,是中国民间的四大传统智力玩具,距今已有几千年的历史。该校老师们常会给学生推荐这些传统的益智玩具,不少学生因此产生了研究益智玩具的兴趣。

2014年,该校引进了3D打印机,并开设了3D打印综合实践课,课堂上同学就讨论能否利用3D打印机打印一些中国传统益智玩具。于是学生们自发组成小组,对3D打印益智玩具展开研究。

“鲁班锁你中有我、我中有你,体现团结和包容。鲁班锁也是中国传统文化的重要组成部分。”老师张蕾介绍,让学生们研究鲁班锁,并制作鲁班锁不仅可以让学生更好地理解鲁班锁的卯榫结构,也可以激发学生创新思维,传承中国优秀传统文化。

杨家林、邱禾佳、程可欣三位同学目前已经升入了中学,但对小学时期制作鲁班锁的经历还历历在目。邱禾佳告诉记者,“我们查资料发现‘鲁班锁’利用的是榫卯原理,有9块结构。”,其中有3块结构是固定的,因此他们精简结构,设计出6块结构的“鲁班锁”。历经数次调整,邱禾佳和小伙伴们通过3D打印技术,做出了完美的“作品”。他们制作的鲁班锁赢得了同学们的喜爱,被学生们誉为“最适合小学生玩的鲁班锁。”

小学生们制作的鲁班锁获得国家专利,体现了学校课程改革的成果。朝阳区实验小学党总支书记胡爱国介绍,学校自2010年开始启动课程改革,目前已经初步形成了以“幸福教育”为理念的课程体系,除语、数、英学科之外的其他课程,学生可以从一年级就开始参与自主选择课程及任课老师。今年9月起,该校三个校区的学生累计可以选修的科目近400门。

胡爱国表示,多元的可选择课程促进了学生的成长。据不完全统计,在2013年至2017年,学校获得了10项国家级奖励、35项市级奖励;学生则获得了482项国家级奖励、664项市级奖励。除鲁班锁专利外,学校学生还曾获得柔性夹具、环保捕鼠筒、自动浇花器和自动浇花架、密封装置、冷暖箱等专利项目。(记者 杜燕)
