Adjustable frame tightness

Magnetic bolts have been a thing a while now. Is there any reason why we couldn't have frames with adjustable tension? Would also mean frames never failing as if it gets loose you just tighten up. A simple option with loose and tight extremes only seems very easy to implement, with some more RnD offering true variable tightness.

I was thinking the same thing a while back when I saw these. Only for me, I would like to loosen the joints for play time and then tighten them back up for posing. Stuff like this not being implemented make me wonder what level of technical expertise is used in the design of these skeletons...

Yeah that was my thinking exactly. Can even just loosen certain joints like hips and knees for fun time. These dont even need to be structural they could just be an additive locked/open feature.

I'm pretty technical and have a little experience of Chinese manufacturing, but if you look at things like how they weld the waist on the skeleton and the constant breakages tells me the industry sadly is still very much a sellers market.

Things like basic facial expressions (blinking) are super easy to implement yet nowhere to be seen.

Big strides needed for sure.

This magnetic screw has very low torque, at best it can do is between semi to completely loosen.

I've been looking for a doll recently and am considering getting one with a fully loose skeleton. I prefer a soft, floppy feel rather than a stiff one. Are there any models you would recommend?

Me too, my next one would be semi-loosen. I also wonder it doesn’t need steel skeletons anymore because complete and semi-loosen bodies don’t stand up at all. It would be a huge weight deduction if using fiberglass or even plastic skeletons for non standing dolls.

The only drawback is when you carry it, it’s “slippery”, like carrying a drunken person.

I think the whole steel skeleton is like 5lb and a fiberglass or plastic one would be quite near that. The vast majority of the weight is the solid rubber infill.

Rubber infills? So the silicone is only an outer layer? I didn’t know that.

no i'm saying because its solid rubber inside and outside as one layer it's heavy. it would be lighter if it had empty insides or foam core or w/e

Plastic skeleton and/or foam infill would be possible with Silicone, but not TPE, it's poured molten.

I totally understand what you’re saying and I agree with you however they could have an interior metal core and then the outer normal shell. Pour the molten TPE into this setup formed between the two - let it cool - remove it from the outer shell, cut it away from the inner core and then you’d have a hollow skin suit, and then wrap that suit over your foam corr with plastic skeleton since it’s now cold and doesn’t risk melting those things. It’s some extra steps or whatever but this would solve everything weight wise

From a manufacturing point of view that's a lot. It could be done of course but the labor and quality control would be an issue, also, many members here have stated the stainless skeleton isn't where dolls pick up weight, it's usually a very thin wall.
One approach that might be more practical would be to research types foam and other squishy materials and just find one that's not phased by high temperatures.
