Tastes may vary but it looks like it's constructed pretty well. If there are grooves for the base and top of the wine bottle those turn buckles will hold it tightly in place. Not my thing, but nice upcycling design.
I tend to agree. It's DIY tensegrity, and not really offensive as such. I wouldn't buy it, but there's $55 worth of material and labor and creativity here.
How is it tensegrity with rigid bottles used as support?
Tensegrity, tensional integrity or floating compression is a structural principle based on a system of isolated components under compression inside a network of continuous tension.
The bottles are in compression, while the tensors are providing... You guessed it, tension.
Tensegrity usually means integrity from primarily tension, like cables used as the main struts for something. This just looks like it's bottles as a structural element with rods preventing them from coming apart
I don't know that I would go so far as a describing it as tensetrity, but the majority of the load on the shelves is held through the I/J hooks in between the bottles. The bottles are there more for stability.
Those are just pulling the shelves together and putting more pressure on the bottles.
This shelf is designed with "sit in a chair and fly by lifting the chair" logic.
I think we're in agreement in both those regards.
I meant stability in the sense that it's preventing shelf rotation. It does the job I guess, but I don't see this being a particularly long-lived piece of furniture.
They could have glued the bottles then they don’t need the tension springs. Or if they prefer it to come apart, glue the bottom of the bottles and then run a bolt through the upper shelf down into the bottle opening below it.
The springs make me nervous.
Not springs, turnbuckles.
