一篇关于无溅小便池设计的物理原理文章在HackerNews引发113条讨论,核心涉及流体动力学与表面张力优化。对做机器人/硬件的工程师有启发:日常物理问题的优雅解法往往比复杂传感器方案更可靠。

这个帖子在HN爆火本身比技术内容更值得注意。113条评论里大量工程师在讨论如何用简单几何改变流体行为,而不是加传感器或主动控制——这种'减法思维'在AI硬件创业中极其稀缺。

做具身智能或机器人抓取的团队可以想想:你们有多少问题是在用深度学习硬怼,其实改改物理接触面就能解决?MIT的Daniela Rus组前几年做软体抓手时就靠材料纹理设计省掉了力控闭环。这个帖子是个提醒:先问物理,再问模型。

核心争论:优雅物理设计 vs 实用商业约束,以及坐便是否为真正替代方案

I'm honestly passionate about this topic. For a while, around the time that urinals started to appear without water, I dealt with some serious splashback issues. I forget when I started aiming for the back of the urinal. I'm assuming that's the deflection angle the paper discusses. At one point I re

The basic problem is that making the angle low makes the urinal take up more space. Businesses don't like that.
