问题定义The question

如何让假肢随孩子成长而适配，并把更换变成一项持续的服务？How might a prosthesis adapt as a child grows, turning replacement into a continuing service?

儿童成长期要反复更换假肢，每次都要重新评估、制作和支付；孩子是否愿意佩戴，也取决于它是否「像自己的」。Growing children need new prostheses again and again—each time a new assessment, fabrication and cost—and whether a child wears one depends on whether it feels like their own.

  1. 关键取舍 01Key decision 01

    为什么做「模块化 + 服务」，而不是一件更好的假肢？Why modules and a service, rather than one better prosthesis?

    再好的单件假肢也会被「长大」淘汰。把接受腔、连接件和末端模块分开，让变化最快的部分单独更换，旧件通过订阅与返还回收。Even an excellent single prosthesis will be outgrown. Separating the socket, connectors and terminal modules lets the fastest-changing parts be replaced alone, with old parts returned through a subscription.

    代价Trade-off接口让结构更复杂，对适配、受力与安全的要求也更高。Interfaces add structural complexity and raise the bar for fit, load and safety.

  2. 关键取舍 02Key decision 02

    为什么让孩子参与外壳设计？Why let children help design their own shells?

    情感上的接受度决定孩子愿不愿意戴。让孩子参与外壳选择，假肢就从医疗器械变成表达自己的物件；3D 打印让小批量的个性化外壳成为可能。Emotional acceptance decides whether a child wears it. Choosing their own shells turns a medical device into something personal, and 3D printing makes small batches of personal shells plausible.

    代价Trade-off定制会提高成本，因此用外壳预览和颜色选项限定选择范围。Customisation adds cost, so choices are framed as shell previews and colour options.

  1. Ottobock可靠的医疗工具：安全、功能强，但缺少情感与乐趣A reliable medical tool: safe and functional, with little emotion or fun
  2. UNYQ时尚的个性化外壳：能表达自我，但功能与普及度有限A fashionable, personalised cover: expressive, but limited in function and reach
  3. Open Bionics酷的「超能力」装备：有科技感，但价格限制了普及Cool “superpower” gear: technology and imagination, but the price limits access

访谈Interviews
受访者 A · 家长Interviewee A · parent
“孩子长得太快，假肢很快就不合适了。除了花钱，不合适的假肢还会把皮肤磨得很疼。”“My child grows so fast that the prosthesis soon stops fitting. Besides the cost, an ill-fitting one rubs the skin painfully.”
“现在的假肢又贵又让孩子显得格格不入，他会因此自卑。我们需要一个负担得起的伙伴，而不只是一件医疗器械。”“Today’s prostheses are expensive and isolating, and my child feels inferior. We need an affordable partner, not just a medical device.”
受访者 B · 儿童Interviewee B · child
“我的假肢太重了，戴着很累。我长得快，它很快就不合适，一动就磨皮肤，像穿了不合脚的鞋。”“My prosthesis is too heavy and makes me tired. I grow fast, so it stops fitting and hurts my skin, like bad shoes.”
“我讨厌我的假肢，又丑又只有一种颜色，很无聊。别的小朋友都有很酷的东西，我的像个工具。”“I hate my prosthesis. It’s ugly, one colour and boring. Other kids have cool stuff; mine looks like a dull tool.”
