Austrian designer develops a new concept for the door all based on rotating squares

Here’s something you can add to the list of things you never knew existed, but could probably definitely use: it’s called the “Evolution Door,” which is a “flip panel” invention by Austrian designer Klemens Torggler.

Torggler actually has more than one alternative to the classic door concept that’s been around for centuries. They all utilize rotating squares, but some use rods, wheels and a track system arranged in an epitrochoid curve.

According to io9:

The Evolution Door works by virtue of four strategically attached triangles that separate, fold and rotate with a gentle flick of the wrist. It’s a wonderful play on geometry that makes it possible to move the screen from side to side without the use of a track, a topological trick that Torggler says “opens up new applications for the door.”

    seems odd that he set the lower door piece on the outside… wouldn’t that be more prone to rain leaking in?

    not sure how this ‘opens up new applications’ etc … OR how it is superior in ANY way to a hinged door .. looks more expensive , how does it LOCK.. and .. what’s the point? is there something particularly wrong with hinged doors?

    Beautiful! I would love to use this in a residential project.

    What you are missing is in the first demonstration, look how close the furniture is to the door. With a hinged door you have to leave space for the door to swing open, whereas with this door, you only need a tiny bit of space next to the door. It makes your whole room much bigger.

    As for locking it. If you wanted it as a front/back door, you just install the locking mechanism on one side as normal. Once locked, you would not be able to use the fulcrums to open the door.

    Who has this much time to open and shut a door?

    I can think of a couple of ways it would be better than a hinged door. 1st, it opens with very little strength, nice for the elderly and handicapped. 2nd by sliding along the wall it has more room. Having moved furniture thru doorways into small rooms or halls, it eliminates the door being in the way. It would allow more people to help with heavy items.
    I could see how a lock could be set that would keep the panels from moving.
    As for being superior, it would depend upon what you need the door for. For an interior door, it might be more useful than a hinged door.
    It certainly would be better for my bathroom than the hinged door I have. Opening my hinged door cuts off access to the bathtub. Having that door would allow me to go from the sink, toilet, and bathtub as needed with the door open.
    So depending on what I needed it could be superior. As for other things, I am willing to bet that some bright person might be able to take that hinge design and use it elsewhere.

    It’s neat, but I think anyone could tell you this is an innovation for innovation’s sake and serves no practical purpose whatsoever. I don’t see how this actually IMPROVES the actual FUNCTION of the door. Meanwhile it’d probably make the door very expensive, hard to lock, easy to break, and hard to fix.

    Cool theory, stupid idea in practice. Pretty much what a door would be if Apple created one: Neat looking and “cool.” But ultimately the same as any other door except more expensive for the sake of self-serving wow factor that contributed nothing to function.

    I doubt this is being floated as an alternative to an exterior door that needs to be locked or even something like a bathroom doors. There are many rooms where not having to allow for the path of a hinged door into a room is a benefit. Currently you would need to use a pocket door or a sliding door on tracks, it is in these situations where this would be a great and interesting alternative.

    You can’t imagine a single practical purpose? Let’s say you need something like a sliding or pocket door, for space considerations, but don’t have the carpentry skills to install one. This might be a good alternative. Installation looks like it might just involve anchoring two pivot points. And the panels fold small enough to be easily and relatively inexpensively shipped.

    I think this is a solution to a problem that doesn’t exist. For every person who says they can put furniture closer to the door (Yeah I’m always doing that), I’m sure I can find people who say the design of the room doesn’t provide enough space beside the doorframe to hold the door when open. Looks cool. Solves nothing and has to cost way more than a real hinged door.

    How can one slam this door? That´s very important for some of us…

    This would be way easier for a handicapped person to open and would allow more space for a wheelchair.

    It’s amazing. It stimulate the senses. It jiggles the brain a bit. It’s good for one.
    You already knew the answer.

    The POINT, is that a different design, which is MUCH more easy to install than a sliding of hinged door, can also fulfill the needs of the space eating hinged door with its tricky alignment with 4 other planes.
    WHY do you ask questions you should be able to figure out on your own?
    Please use your brain. It might hurt a bit at first, but that’s part of the process. Think!

    NO, it doesn’t ‘have to cost way more than a real hinged door’.
    Have you priced the cost of a new door and tweaked door frame; the cost of having a pro do it? Think again.

    Sliding doors tend to stick, the tracks get all mucky very easily. The apartment I am in now has no door from living room and bedroom. You cannot install the usual kinds of doors because of the design. But there are times when someone comes visiting and you need to change clothes. This door would be a way to offer privacy. Also, when the weather changes, you can have the door keep in a heater or AC for just your bedroom, instead of using energy to heat or cool the entire apartment.
