Automatic door with small sections that open separately & only as far as needed

Couldn't think of a better name within the minute or so it took to post this

This is an idea I've had for years, but never posted because I thought it was not novel. I did a Google search for the title just now, though, and didn't find anything.

The idea is to make a door that works like automatic sliding doors on stores, but instead of one piece on each side, it's divided into several pieces, each one about an inch to several inches high. When you approach the door, these pieces open like a regular automatic sliding door, but instead of all of both sides opening all the way, only those pieces that are actually in your way open, and each one only opens as far as necessary to get out of your way. This is done using computer vision, as well as proximity sensors on the tips of the sliding pieces for fine guidance. Each piece is equipped with a separate motor (which can, obviously, be smaller than a motor that would move the whole door).

The effect is that the opening of the door is the same shape as your body (plus whatever you're carrying), and the rest of the space covered by the door remains closed while you pass through it.

The point of this is to reduce air exchange between the two areas separated by the door, whether this is to conserve heat, humidity, or clean air, or for whatever other reason you want.

This is probably why the Idea here will probably stay HalfBaked. [Vernon, Aug 29 2016]

       Maybe it could be achieved in a lower technology form by making a sort of rubbery diaphragm arrangement that is secured somewhat more tightly at the top end and also at the bottom end, thus elongating vertically the aperture that you plunge into and consequently on the other side, emerge from.

       I like this. You could make the sections out of faux brick and go for the Station 9 3/4 Harry Potter effect.

       Will it make the traditional "Zwishhhhh" sound when it moves ?

       Sealing could get expensive...

       Thanks [LimpNotes]. Where can I buy one? I imagine it's now considerably improved vs. that video from 9 years ago.

       Looks like they had a website up at some point, but its down now. The name of the product was E-Taf Automatic Door.

       How about "Matryoshka Door"?   

       Of course before I read your full description I was imagining the door with a whole lot of nested cut- outs in the shape of people, making the name more appropriate.
