纸张的蜕变:从创意表达至社会赋能

折纸艺术(Origami: 用单张纸张通过折叠塑造三维结构的艺术与技术)不仅仅是儿童的游戏,它承载着从微观神经细胞到复杂昆虫模型的无限转化可能。在日常生活的琐碎缝隙中,通过将废旧收据折叠为百足虫,或者将报纸转化为蜥蜴,这种将“无”具象化为“有”的创作过程,能够极大拓宽个体的空间想象力与创造力。

在这种纯粹的创意表达之外,折纸还具有深远的社会价值与人道主义关怀力量。在疫情隔离期间,作者向养老院老人寄送手工折纸鸟以送去慰藉,并在此后折叠了数百只鸽子与麻雀进行义卖,为纽约市的免费汤厨房和伤病鸟类康复中心筹集了超过4,000美元的善款。这一实践清晰地表明,即使是最谦逊的材料,在倾注社会责任感后,也能转化为服务社区、改善弱势群体处境的强大纽带。在完成这种从个人兴趣向社会实践的过渡后,折纸的结构力学特性进一步引导我们走向了更具技术深度的跨学科探索。

I love origami. I love the way I can transform a simple piece of paper into almost anything -- like a wheel bug, my grandparents (Laughter) or even a neuron cell. I’m 14 years old. I live in New York City. And I’m in ninth grade -- so I'm usually busy with homework or after-school activities. But in my free time, I really enjoy doing origami. Origami is fun, but playing with paper has also shown me that origami has the power to stretch my creativity, help others and even lead to new discoveries. And today, I'd like to share one small discovery that I made and how I got there. So I started folding origami over seven years ago making ornaments for my family’s tiny Christmas tree and getting in trouble in class for turning my worksheets into ninja stars and paper claws. As you can imagine, my teachers were less than overjoyed, but I told them I was making academic weapons. (Laughter) Over time, I began folding more complex origami and even designing my own models. But no matter what, I'm always folding. Give me any scrap of paper, and I'll challenge myself to turn it into something. For example, if I'm waiting in line at Trader Joe's, I might turn a sample cup into a crane or even a super-long CVS receipt -- (Laughter) into a centipede. Audience: Wow! Or even the New York Times into a lizard. And it’s this process of turning “nothing” into something that sparks my imagination and draws me to origami. I've also found that origami has the power to help others. During the pandemic, eight-year-old me wrote cards and mailed origami birds to seniors at my local nursing home to cheer them up during quarantine. And more recently, I've been folding even more origami birds. Two years ago, I folded some origami pigeons. By some, I mean 200 of them. (Laughter) If you couldn't tell, pigeons are my favorite birds. And then the following year, I folded sparrows, another bird that’s overlooked but that I personally love. And I folded 100 of them and sold them alongside the pigeons to raise over $4,000 to donate to my local soup kitchen, as well as a nonprofit that rehabilitates injured and orphaned birds in New York City. (Applause) And so through this project, I was able to see the power of the most humble material, a simple piece of paper, to really help my community.

结构重构:三浦折叠的力学优化

当折纸艺术与现代科学及工程学相遇时,它展现出了解决宏观工程难题的巨大潜力。在航天与医疗等前沿领域,研究人员正广泛利用折纸的折叠机理来设计展开式结构。其中,由日本天体物理学家三浦公亮(Koryo Miura)于1970年代发明的三浦折叠(Miura-ori: 一种由平行四边形组成的重复图案镶嵌结构,可在单一平滑动作下实现极高比例的收拢与展开)尤为瞩目,它不仅曾用于折叠太空太阳能电池阵,也为应对自然灾害中的临时避难所设计提供了全新的结构启示。

为了实现抗灾应急避难所的高效部署与结构强化,作者对其强度重量比(Strength-to-Weight Ratio: 结构所能承受的最大载荷与其自身质量之比)进行了系统性的力学优化实验。通过设计18种不同几何参数(高度、宽度、夹角)的平行四边形折纸模型,并在3种不同克重的纸张上进行共计108次载荷破坏性测试,实验结果表明:

  • 使用最轻薄的纸张、配合最小且夹角最不尖锐的面板设计,能够产生最大的强度重量比。
  • 最强结构可承受接近200磅的重量,而另一款轻量化版本则能承受超过其自身重量10,000倍的载荷。
  • 这种超常的承载力源于紧凑图案形成的类桁架结构,它能将外部集中压力极其均匀地分散到整体网络中。

这一在家中完成的独立研究最终荣获了美国国家级STEM竞赛的最高奖项。它不仅证明了单一纸张所蕴含的无限物理与工程可能性,更为未来研发坚固、超轻量且易于快速部署的可展开结构(Deployable Structures: 能够在外力作用下实现紧凑收纳与大面积展开的结构系统)奠定了坚实的实操与理论基础。

More recently, I've been interested in the intersection of origami and science and engineering. I think it started in middle school when I began going down rabbit holes to see how scientists and researchers and engineers were using origami folds. For example, in space or even to help sick people. But one fold interested me in particular. And this was the Miura-ori fold. It was invented in the 1970s by Koryo Miura, a Japanese astrophysicist. It’s a tessellation, which means it’s a repeating pattern of parallelograms. And the way these parallelograms are arranged, they're able to fold down to an extremely compact size in one smooth motion. This makes Miura-ori an efficient deployable structure. It’s even been used to fold a solar array that was sent into space. And last year, I was also reading the news about natural disasters like Hurricane Helene. And I saw so many people displaced. And it made me wonder if Miura-ori could be used to improve emergency deployable shelters by making them stronger and lighter. And so for my eighth-grade science fair project, I decided to study Miura-ori, and how I could optimize its strength-to-weight ratio. I started out by designing 18 different folding patterns. These had different heights, widths and angles of the parallelograms in the pattern. I tested each of these patterns across three different paper weights, and each of those variations twice, for a total of 108 Miura-ori that I folded and tested. And for each of these Miura-ori, I wanted to see not only how much weight they could hold, but also how many times their own weight they could hold. And so for two months, I transformed my family's small New York City apartment into my testing lab with Miura-ori all over the place. When I was first starting out, I grabbed basically every heavy book and item, and I stacked them on top of the Miura-ori. But I quickly realized I didn't actually have enough weights to accurately test the models. And so I asked my parents to buy some really heavy exercise weights. 250 hours later -- and after a lot of heavy lifting -- I found that the Miura-ori with the smallest and least acutely-angled panels made out of the lightest paper had the greatest strength-to-weight ratio. The strongest pattern held almost 200 pounds, and another lighter version held more than 10,000 times its own weight. I found that the stronger patterns were more compact, and they also created truss-like structures that were able to distribute pressure evenly. It's amazing that something can be so strong and yet so lightweight at the same time. And it's exciting to think about what potential applications a fold like this could have -- maybe even helping to imagine a better emergency shelter one day. And so this work that I did by myself at home led to me receiving the top prize at a national STEM competition last year. (Applause) As you can see, I was really shocked ... (Laughter) to receive such a big prize for simply playing with paper. And so in the future, I definitely want to keep exploring and learning. But most of all: to keep playing with origami so I can continue to discover all the possibilities a single piece of paper can hold. Thank you. (Cheers and applause)
