I was experimenting on google sketchup, not actually anything to do with seasteading, but trying to create a 3d representation of an icositerachoron (a theoretical 4D shape). One of the cells (4D equivalent of faces) I made was, in my opinion, a very good shape for an interlocking platform piece on a floating (or partly-floating) platform. It was an irregular octahedron. The way it works, is that you can interlock, say, three in a row, and the middle one couldn’t be pushed out upwards, forwards or backwards. The only way to get it out is by removing one to the side of it, when it can be slotted out sideways. It is not an overly complex shape to manufacture either. the only downside is that it will only interlock in a row, not in a column.

It has two equilateral triangles at either side, one upside down, but with each point of one triangle lining up with the midpoint of the opposing edge on the opposite triangle, so like a star-of-david, but with the two triangles separated. Each point is then connected with the two opposing points on the opposite triangle. I will upload an image soon, but does anybody else know what I’m talking about?

It’s similar to one of the connecting mechanisms described in another thread. Much like the tire-testing pneumatic thing I once described for use between structures, with pneumatic shocks in place of solid connections, allowing for pitch/roll/yaw differences between structures at sea…

I don’t remember which thread and I don’t have anything onmy computer…

Yes I got the inspiration from the hexagon tile things suggested on another thread, but I think this would be sturdier as it interlocks in more than one direction. I haven’t seen your pneumatic thing, sounds interesting though.

Please don’t accuse me of plagiarism, it was, as I said, an accidental discovery which I thought might work in this. I may have got the wrong end of the stick, as I am sure you would not make such an accusation or assumption, but that is what it sounded like.

Take a triangular base, attach 2 shocks at each point, then mate the 2 shocks from a given side to the corresponding point of an inverted base. Allows for simultaneous movement on all 3 axis’…

Cool, that, by the sounds of it, is the shape I found, although I had not thought of it as that at all, but yeah, that sounds like it should work, as far as I can see. It would also give it flexibility while maintaining the integrity of the structures around it. Of course, I know little about mechanics, but well done.
