The kettle in her grandmother's kitchen had been repaired four times. The handle was wrapped in blue tape, the spout was bent, and the lid no longer sat flush, so steam escaped in a thin whistle audible from the next room. Su Wan had grown up listening for that whistle. Now, in her third year of industrial design, she could not look at the kettle without seeing a list of failures.
祖母厨房里的那只水壶修过四次。手柄缠着蓝色胶带，壶嘴弯了，壶盖也合不严了，蒸汽便从缝里挤出来，发出一声细细的哨音，隔壁房间都听得见。苏婉从小听着那哨音长大。如今她读工业设计三年级，再看那只水壶，眼里只剩下一长串缺陷。
Her grandmother had arthritis in both hands. She could lift the kettle only when it was less than half full, and could not turn the stiff tap without both wrists. The family had bought her an electric kettle with a sleek steel body and a touch panel. She had used it twice and put it back in its box, and gone back to the old one on the stove.
祖母双手都有关节炎。壶里的水超过一半，她就提不动；那个发紧的龙头，她得用两只手腕一起拧。家里给她买过一只电水壶，钢身光滑，触摸面板。她用了两次，就把它放回盒子，又回到炉子上那只旧壶。
For her final project, Su Wan decided to design a kettle for her grandmother. She measured the height of the counter, the width of the sink, the strength of the old woman's grip with a simple squeeze tool. She filled a notebook with drawings of handles, spouts, lids, bases. On the first page she wrote a question she did not yet know how to answer: 'What is elegance for?'
毕业设计，苏婉决定为祖母设计一只水壶。她量了台面的高度、水槽的宽度，又用一个简单的握力器测了老人手上的力气。笔记本里画满了手柄、壶嘴、壶盖、底座的草图。第一页上，她写下一个自己还答不出的问题：“优雅是为了什么？”
The studio was white walls and north light. On critique day, twelve projects stood on plinths like monuments. Su Wan's kettle was the only object with a visible seam, a wide loop handle and a lid that lifted with a lever rather than a twist. Professor Deng walked past it once, then came back and stood for a long time.
工作室是白墙和北面的天光。评图那天，十二件作品立在高台上，像一座座纪念碑。苏婉的水壶是唯一一件带着明显接缝的作品：宽大的环形手柄，用杠杆而不是旋转来开启的壶盖。邓教授从它旁边走过一次，又折回来，站了很久。
'It looks like a medical device,' he said at last. The room laughed, not unkindly. 'The handle is clumsy. The seam interrupts the form. You have designed for one person and called it design.' Su Wan felt her face heat. She wanted to say one person was enough, that her grandmother's hands were as real as his grid. Instead she wrote down his words, because he was not entirely wrong: the object was not beautiful as the others were.
“它看起来像医疗器械，”他终于说。教室里笑了，倒没有恶意。“手柄笨拙。接缝破坏了形体。你为一个人做了设计，然后把它叫作设计。”苏婉觉得脸发烫。她想说，一个人就够了，祖母的手和他的网格一样真实。但她只是记下他的话，因为他并不全错：这东西确实不像其他作品那样漂亮。
That night she took the kettle to her grandmother's flat and watched her use it. The old woman filled it at the sink, set it on the stove, and waited for the whistle. Then she did something unplanned: she hooked the handle over the tap to steady herself while turning off the gas. The kettle was not only for pouring. It was also a support, a signal, a reason to stand up.
那天夜里，她把水壶带到祖母家，看她使用。老人先在池边接水，放到炉上，等哨音响起。然后她做了一个苏婉没料到的动作：把壶柄挂在龙头上，借力稳住自己，腾出手关煤气。这只水壶不只是用来倒水的。它还是扶手，是信号，是一个站起来的理由。
The final exhibition was held in the white studio, with the public invited. Su Wan's board had changed. There were still drawings, but the first panel was a photograph of her grandmother's hands, and beneath it, in large type: 'What is elegance for?' The kettle stood on a low table, so visitors had to bend to see it.
毕业展就在白工作室举行，向公众开放。苏婉的展板变了。图纸还在，但第一块展板上是祖母双手的照片，照片下方用大字写着：“优雅是为了什么？”水壶放在矮桌上，参观的人必须弯腰才能看清。
Professor Deng came with the judges. He picked up the kettle, filled it from a jug, and poured. Then he did what no one had done in three years: he closed his eyes and listened to the whistle. 'It is loud,' he said. 'On purpose,' Su Wan said. 'She cannot see the steam from the stove.' The judges wrote. One asked whether the design could be produced cheaply. Su Wan said that was the next question, and she had brought a cost sheet.
邓教授带着评委来了。他拿起水壶，用水罐注水，倒出来。然后他做了三年评图中谁也没做过的事：闭上眼听那声哨音。“很响，”他说。“故意的，”苏婉说，“她从炉边看不见蒸汽。”评委们记录。一位问，这设计能不能低成本生产。苏婉说那是下一个问题，她带了成本表。
She did not win. The award went to a lamp made of a single folded sheet, and it was genuinely beautiful. But the kettle entered the department's small permanent collection, with a note in the catalogue: 'Designed with one user, for many.' Su Wan called her grandmother from the corridor. 'They put it in a case,' she said. 'Can I still use it?' her grandmother asked. 'Yes,' Su Wan said. 'That was the whole point.'
她没有得奖。大奖归给一盏用单张薄片折成的灯，那确实很美。但水壶进入了系里的小型永久收藏，图录上写着一行说明：“与一位使用者共同设计，为许多人而做。”苏婉在走廊给祖母打电话。“他们把它放进玻璃柜了，”她说。“我还能用吗？”祖母问。“能，”苏婉说，“这才是重点。”
