A Fantastic FAILURE!

You’ll like this (I think)

It’s a prototype carabiner-style clip that failed spectacularly.

Usually I fail at first with new prototypes… then start making changes and it slowly starts to look like it might work.

But, this time is different:

I just can’t get this to work. Not even close.

Take a look at this – I think you’ll see what I was trying to do with it…






Oh, and by the way…

The reason it failed is because that “springy” looking part was just too “wobbly”.

And, if I strengthen it at all, it gets too stiff. Frustrating.

    This shape is awesome looking. What if you just did a straight part in the “springy” area that was milled diwn to a smaller width so that it had enough bend to it

  • Joe w says:

    You could reduce the number of bends in the spring to make it less wobbly, no?

  • Bob Lukach says:

    Interesting idea Magnus. There probably is a thickness for the spring part that would work, but trying to find that would take a lot of time and titanium. There is a workable design here, I’m just not schooled in the engineering aspect of this. I say keep at it.

  • Viktor says:

    Can’t you make it a crescent? Like the TiTweezers?

  • B Alan Eisen says:

    This will work if you thicken the spring pard but put a relief slot down the middle. I would simply thicken it and leave it stiff. I would put a hook on the end of the closure. Just my thoughts.

    Make one or two of the folds thicker then the rest. It will stay aesthetically pleasing but might strengthen it just enough to still work..

  • Nate says:

    You should look into lock bar cut outs on knives and create something similar. Perhaps instead of having the clip open inwards which I find a design flaw in normal carabiners because it closes in whatever on the carabiner, have it open outward and have inward pressure by use of a “lock bar” cut out hope that makes sense.

    I like the idea. Don’t go with Sunny’s idea though! (the C10) – those Bauhaus biners to have side play in them. The cool thing about them is that they’re single piece items. Though it’s not a surprise that Sunny is now doing a 2 piece biner (Handgrey). I found the spring to loosen/give in mine. The only other hopeful potential idea I can think of is from what Ti2 is doing with the Parabiner pb9 – some kind of special labyrinth torsion spring that looks like it’s pretty solid – but I don’t know if it only works in a 2-piece system. All in all, the sucessful single-piece biner is somewhat like searching for the philospher’s stone.

    • Thank you for your comments Michael!

      Ah, I did not know the Bauhaus carabiner had any sort of side-play …makes me not feel so bad about my design. 😀

      Yeah, I’m still working on it…

      I have another idea I’m about to get water-jet cut – so, give it a few weeks, and hopefully there will be an Update with the results (although, realistically, I’m not holding my breath… just optimistic!)
