If a toothpick's diameter is 2mm (0.0787 in) and its length is 2.5 in, then it has a volume of π*0.5*(0.0787 in)2*(2.5 in) = 0.0243 in3. That gives you (16 in3) / (0.0243 in3) = 658.436 toothpicks to work with. With that, you can get 4.318 ft side to side, or 137.174 ft top to bottom. The rule should should be phrased as "it must fit inside of a cube with volume 16 in3".

I'm wondering if it has an airflow sensor or something similar to sort of know whether it's in open air or a pocket

level 3

I'm thinking it has an accelerometer in there. when it measures forces close to 0g for a certain period of time, it deploys.

level 4

They fold up into the case though, so maybe if there's any contact on the case or resistance trying to come out, it doesn't deploy.

In that case, if you jump down from a meter or so, it'll deploy in your pocket.

Using acceleration isn't a very unreliable method. It's been used in laptops for years to lock the spinning harddrive when it's dropped to prevent damage. It isn't as loose of a concept as detecting that acceleration is increasing. They map the detected acceleration and if it can be fit to the equation for acceleration due to gravity, then it determines it's in free fall. You can do this even if the device is spinning or tumbling. It takes some math, but can be done.

For a prototype it's phenomenal.

I'd rather have false positives than false negatives. If I am paying ~1000$ for a phone a few inconvenient episodes are worth not buying a case.

Granted this one is pretty bulky, but this is precisely what I have been complaining for a few years now. Phones are so sleek that they are delicate; so delicate they need a bulky case that makes them ugly. Why pay 800$++ for a phone when it looks like a shitty version of itself inside an Otterbox?

Edit: If an innovative phone manufacturer were to use a sensor along the edge to detect if the phone is being held, coupled with the light sensor to know if it's inside your bag/pocket, it should improve the reliability.

level 2
111 points · 2 months ago

It can have those electric sensors on the back of the case like old toys that you have to touch two metal pads for it to squeak/peep when you let go of those AND the case senses sudden acceleration then maybe they can deploy. Also the case can have a “lock” feature where they won’t deploy till you toggle it off.

level 3

Having the toggle totally negates the purpose though. Who plans on dropping their phone?
