Extraordinary practical models?

[Gerardo]

Hi everyone,

I wanna explore extraordinary practical models I haven't met yet. I hope it's not too hard!

I'm looking for something mid intermediate to complex, generating an astonishing model that's very useful. Can you think of one or two examples? What are their names and who are their creators?

C'mon guys! With so many books and magazines, there has to be at least a couple

There are many nice models that are useful for advancing your origami skills. Fewer models have practical everyday use, although they do exist, such as a wallet, different planes, gift boxes, the water balloon. Just Google what you might be interested in. Here is an Architectural CP from a very interesting book: "Why Buildings Stand Up." This structure can be used as a much stronger bridge than a simple accordion fold...

Thanks Hank for your response.

What I'm seeing is that most practical models are of a simple to mid intermediate level, unlike representational origami for example (animals, characters, fictional creatures, etc). There are models like To be or not to be by Andrey Ermakov or The nose - An eye glass stand by Jens Kober, which aren't simple at all.

So I'm looking for other practical models of that level of complexity... hopefully models that are very useful and simply extraordinary!

Can you help me guys? PLEEEEASE!

There has to be a convention book or an issue with a somewhat complex practical model!

Can you guys take a look at yours?

any origami box can be turned in the a dice by simply putting points on it. also there are many origami book designs, and chess/checkers boards. other than that I cant think of any more off the top of my head

[Gerardo]

Thanks OrigamiGeek!

Any other models guys ?

Andrea Michellini's card purse is really useful. My partner uses it for several years now. It provides space for eight cards and has an additional pocket for receipts. Folded from Elephant Hide it lasts for about two years before I have to make him a new one.

Thanks origami_8! It doesn't look as complex as I was hoping but I REALLY do like the model! Where can I find diagrams?

Guys, can you please think of any other relatively complex practical models you can share with me?

[origami_8]

Sorry, but I'm not aware that any diagrams for this model exist. I learned it in 2009 at the Italian Convention from Andrea himself.

As for complex practical models I think that you have a misconception. To be really useful, practical models have to be simple. Most things I need, I need immediately. In most cases there's no value for me if I have to sit down for an hour or more to fold something that I intend to use. Things that you use have the tendency to brake down rather fast. So it would be a waste of time to make something complex that lasts maybe less time than I needed to fold it. The most useful models for me are simple boxes to shortly hold some small items like for example screws or the traditional seed pack for exactly that purpose.
We can argue about action models being practical, but even there most models are rather simple and fast to make. I really do know a lot of models, but I'm not aware of any complex practical models. There are some in the low intermediate range like for example the money purse by Yuri Shumakov, but nothing I'd consider complex.

It may be time for you to evolve in your Origami skills to start designing and Diagramming. Then, you can combine components from other models to create something practical. I believe that you will discover that this route is much more challenging than folding an existing complex model.

To start you off, I've been looking for an Origami delay component, which might eventually evolve into a simple timer. The delay component serves as a preliminary trigger for a second action. I started looking for this idea after seeing the fantasy Origami Frog on the TV show, The Mentalist. He put a frog on a table and walked away, then a few seconds later, it jumped... nothing exists in paper to accomplish this, but a complex model that exploits the tension of paper and a lock might create a delay trigger.

I believe that Yoshide Momotami has a old blooming flower that vaguely relates to this idea. He folds the flower, twists it closed, then adds a drop of water, and it 'blooms'. I'm sure that you've folded Origami models that were frustrating, b/c they came apart, without a little wetfolding help ... That might be a place to start, if you're game.

And, if you're successful, FirstFold has some terrific action models that might put the trigger to good use. In addition, you might be able to copyright, or even patent the idea...

Thanks origami_8. I understand what you say and that is why it has to be so dificult to find something relatively complex and of the "practical" origami category. My thoughts now are, if To be or not to be and The nose exist, then maybe others have also created "complex" practical models.

Sounds like an interesting idea. Thanks for offering it.

take a look at this article (not sure if that fits your definition of practical origami)

http://www.ericjoisel.com/resources/media/lognon.pdf

they are using what look to be fairly complex (or at least tedious) tesselations as molds to prepare fabric for fashion design ...

Not really sure if it's what you're looking for, but I designed an origami hair clip for a friend a while back. It's in my DA gallery somewhere, and I might be able to post the CP at some point.

WOW... that was unexpected! Thanks jeko! Not at all what I had in mind, since I was thinking of something of a more ordinary every day use... that was why it was so surprising . Thanks for sharing it!

I had no idea... thanks for sharing it Baltorigamist! Would you make and upload a demonstration video of how it's used in long hair? I would so love o see that!

It would be hard to take a video simply because 1) the locking system is fairly complicated, especially with a small piece of paper, and 2) I have no idea who would volunteer to be a "model." But I can explain how to fold it.

1) Take a bird base and point-split one of the flaps at its base. The two new points should line up with the center flap. (The raw corner can be folded inside, and the resulting edge is inside reverse-folded.)
2) Sink the side edges in and out where the two angle bisectors would meet. Then spread-sink the six edges of the three flaps on top.
3) Arrange the three flap to form roughly an equilateral triangle. The model will be 3D.
4) Make an asymmetric triangular twist from the resulting point.
5) Narrow the two near points on the bottom by pinching them in half. Lock them together by folding the tips inside the raw edges (so it looks like a normal hair clip). Then fold the tip of the far flap inward, and the model should function at least a few times.

Here's the CP:

There are two missing creases, but it should be comprehensible.
