Well, it looks cool.

It would probably be slow to make any inroads into defence products, what with NATO standard attachments; unless and until such a system became widespread in civilian engineering.

There does seem to be a lot of surface contact though. I can imagine you’d have an awful lot of stiction when it came to disconnecting something, particularly on anything that might be subject to ingress of dirt and moisture.

Is this a ‘new twist’ on the stepped interrupted screw?

Hi, Dunservin. That is still a traditional male/female connector, while this system is said to be asexual. So instead of items B and C connecting to A but not each other, A and B and C can connect in any combination.
The asexuality seems to be one of its key features. Been trying to think of some defence related kit where that feature would come in handy, but can’t.

@BB

The asexuality of such devices would have dismayed the gnarled old retired Chief Petty Officer instructors at Dartmouth who somehow managed to apply innuendo to every aspect of seamanship, especially fuelling at sea and knots, bends and splices. Fids were flying all over the shop. ;-)

Sailors’ frenetic tossing as they struggle against the horn, wet seamen all over the poop deck, the cook polishing his bell for hours every day, and the salty spray upon your face… I can’t imagine how you can find innuendo in the Navy.

A combination of my job as a lawyer (there is soooo much weird sex out there I feel positively left out), and the cumbrian place names can be priceless.

Some time ago, the complainant in a sex case (whose credibility had been well and truly shot by this time, so no one in court was feeling very sympathetic). Complained that during a long relationship she had been repeatedly forced to commit oral sex.

Next question from prosecutor:-

” Was it then that you moved to Cockermouth?”

What followed emulated the classic Biggus Dickus bit of Life of Brian.

Many thanks for the comments and interest- Rotite can be modified in almost limitless ways to suit the task in hand – with regards to “sticktion” Brian Black referred to , rotite can actually act as a self clearing mechnanism, even in the Hermaphroditic (both male and female) variants.
we are also pleased to see interest from the military arena as this is one of the key areas of opportunity for Rotite® due to its high strength, its ability to make electronic and physical connections , it’s intuitive action and its silent operation!
Any suggestions of applications from experienced people like yourselves or potential inroads would be greatly appreciated.

This is it ! Rotite® offers both high strength fastening and electrical connectivity. it also has the ability to sequence those electrical connections made ( maybe useful for protection of sensitive equipment ie. earth first …and so on ). Uses may be in apparel / electronic interfaces / docking charging etc. Hermetics may also be included !

Rotite need not be a series of formations distributed about the surface of a disc , they may be predisposed about the outer perimeter of a pipe / hose. Such connectors could also be hermaphroditic !! hose to hose, hose to manifold etc etc..see

once again thanks for the dialogue – we will be only too happy to tell you more !
there is much much more to this system than that that is available on the website at rotite.com

Well… the immediate thought on how to use it militarily that came to my mind was quick reloading high capacity ammo drums for automatic weapons. Ammo containers for high calibre weapons is also a possibility but the current screwcap system already works well for those.

The other possibility is mobile command posts, but the current accordian like system for that might be better than a twist and pull system with the obvious question of how do you twist a command post.

So what holds it closed? Especially the short throw samples – they look like they would self-loosen under load.

What you can see on the website and so on are merely examples of the principal of the mechanism which effectively is a free mechanism ( up to the specified rotational extent ). However Rotite is a “complex mecnanical “interface” anything that intersects this interface constitutes a lock or locking device.Also there are numerous surfaces interacting at various tolerances wherein a reduction of the mechanical clearances creates internal interferences to hold the two component parts together. The beauty about rotite is that may also have differing locking functions that may be sequenced at differing stages along the mechanical extent.
In response to Observer – Rotite may be predisposed about other rotational restraints or may have an intermediate component….This REMOVES the need to rotate either object
