Just Add Cardboard

Hinged cardboard clips. Make any angle you want!

Up to 5% influence

Instead of fixed angels I have designed clips that will hold any cardboard up to 1/8" thick, even single ply card stock, and can be bent to any angle. The clips have little nubs to hold the card board securely and best of all each clip half is made from two identical parts that would be easily injection molded and then glued or plastic welded together. This means you only need to make two sets of molds, we'll call them A and B. One half of the clip is made from two parts from mold A, and the other half of the clip is made from two parts from mold B. Because the angle is adjustable you could even use them with octagons to form a geodesic dome. The last two pictures are of the two parts as they would be molded to show how simple and cost efficiently they can be produced.

This design does NOT meet the asked for requirements. This design cannot accomdate cross sections or multiple intersections.

have posted two ideas on here, this hinge idea, and another one that is simpler and cheaper to make, but really, why not both? I think a really cool kit could include a number of these cheap one angle connectors and several hinges. It would really add to the functionality of the kit and make it look more like a high end product. Say a kit with several of each of the extruded pieces and 4 or 6 hinges I am thinking a nice kit like 8x180*, 8x90*, 4x45*, 4xTs, and 4 or 6 Hinges. A well packaged kit like this could really sell well. If you like this idea, maybe vote for both?

Couldn't these two parts be completely identical? Similar to the two plates of a door hinge, the parts line up when one is flipped in reverse. Now imagine if the cylindrical edges on the centers of those door hinge plates had teeth. The teeth will nest into each other when the hinge is set into the desired position. But the teeth can also be squeezed or pulled apart with just a little bit of effort to reposition the hinge.

This would keep the production down to one mold.

You could do it with one mold, but then it would then require a pin like in a door hinge. I'm thinking that having two molds to make parts that then snap together might be better.

These look very sturdy and can be moved in different angels. Just need to make sure the support from one clip to the other is secured.

Like the feel of this - looks great too. If the arm (that forms the hinge ) on each part were a little longer then it might be possible to get angles of less than 90 degrees also if the kiddies needed them. either way great idea (shooting myself in the foot perhaps!!)

If they have difficulty holding after printing, maybe a firm snap on ball and socket type joint, that will allow the pieces to swivel and turn to multiple angles could be a possibility (the width of the clips might have to be narrowed in this case-like two skewer forks connected on a swivel. I like your design the best, your longer clips are the way to go for stability, and ease of use.

These could also be marketed as useful for making hinged displays for school projects. That could broaden the customer base a bit.

Great idea, once the angle is chosen how does it maintain that position? Is it a ratchet-type action?

On these files it is simply a tight fit between the two hinges, but it could have ridges, silicone, or an o-ring added to make it hold the angle better. These things will make it a little more difficult (not quite as cheap)to manufacture. I don't think it needs it since the hinges will naturally be a little stiff and most structures support against each other. I'm going to send some of these to a 3D printer now to see how well they work.

Nice if they hold, I think they are gold!

About This Project

Concept Phase

In this project, we want you to submit sketches, images, videos, and other visuals that illustrate industrial design directions for Michael Muscarella’s Cardboard Connectors.

We’ll use the top concepts as a starting point for our continued ideation, sketches, sketch models, etc..

In this round, you’ll want to examine the possibilities of what this product could be, including what materials we can use to make the item. Think about whether it’s a system of parts or a whole product, or what the buying experience could potentially be. We’re looking to select several winners to form the foundation for continuing onward!
