问HN：为什么没有合身的法拉第iPhone手机壳？
我一直在研究隐私技术，并注意到了一些奇怪的现象：
<p>存在相机滑动保护壳（如Spy-Fy等）——它们可以阻止物理相机的访问，但并不提供信号保护。</p>
<p>存在法拉第袋（如SLNT、Mission Darkness等）——它们可以阻挡所有射频信号，但你必须将手机从保护壳中取出并放入袋子里。</p>
<p>但是没有人制造出一种合身的iPhone保护壳，能够将这两者结合起来——一种可以一直留在手机上的保护壳，配备一个可展开的法拉第屏蔽，可以在不取下设备的情况下随时开启或关闭。</p>
<p>我花了一些时间进行市场调研，并制作了一份完整的概念方案，如果有人感兴趣，我很乐意分享。竞争空白似乎确实存在：</p>
- 当前隐私保护壳市场：$30-40的相机滑动保护壳
- 当前法拉第袋市场：$60-100的袋子
- 集成双模式保护壳：价格在$149-249之间</p>
<p>使用场景似乎很明显：那些希望随时获得全面隐私（相机+信号），而不想麻烦地将手机从保护壳中取出并放入袋子的人。</p>
<p>所以我想问HN社区：</p>
<p>为什么这种产品不存在？</p>
<p>是因为：</p>
- 工程上不可能？（无法通过可展开机制获得合适的射频密封？）
- 市场太小众？（相机隐私和信号屏蔽之间的需求重叠太小？）
- 有人尝试过但失败了？
- 法律/监管问题？
- 我只是遗漏了一些明显的东西？</p>
<p>我并不打算去开发这个（没有硬件经验），只是出于好奇，想知道为什么会有这样的市场空白。</p>
<p>如果有人对拆解我的完整概念方案和市场分析感兴趣，我很乐意分享。</p>
<p>谢谢！</p>

I've been researching privacy tech and noticed something odd:<p>Camera slider cases exist (Spy-Fy, etc.) - they block physical camera access but offer no signal protection.<p>Faraday bags exist (SLNT, Mission Darkness, etc.) - they block all RF signals but you have to remove your phone from its case and put it in a pouch.<p>But nobody makes a form-fitting iPhone case that integrates both - a case you leave on your phone with a deployable Faraday shield you can toggle on/off without removing the device.<p>I spent some time doing market research and built out a full concept deck I'd be happy to share. The competitive gap seems real:
- Current privacy case market: $30-40 camera sliders
- Current Faraday bag market: $60-100 pouches
- Integrated dual-mode case: Would sit at $149-249<p>The use case seems obvious: people who want on-demand full privacy (cameras + signals) without the friction of removing their phone from a case and putting it in a bag.<p>So my question for the HN community:<p>Why doesn't this exist?<p>Is it:
- Engineering impossible? (Can't get proper RF seal with a deployable mechanism?)
- Market too niche? (Demand overlap between camera privacy and signal blocking too small?)
- Someone tried and failed?
- Legal/regulatory issues?
- I'm just missing something obvious?<p>I'm not looking to build this (no hardware experience), just genuinely curious why this white space exists.<p>Happy to share the full concept deck and market analysis if anyone's interested in tearing it apart.<p>Thanks!
