Remote-controlled Bolts and Screws 318

Winter writes "SMT Magazine has an article on intelligent fasteners (screws, bolts...) that can fasten themselves or by remote control. Usage for this seems mainly to make sure normal people cannot change parts in their car themselves, and only allow for authorized parts and service. Of course, a hacker might also have fun and disassemble the neighbours car."

            It isn't that..... Most non-HD mufflers come under 100dBs (which is a poor way to measure sound intensity, but that is another discussion). The Harley folks make them loud on purpose so you can hear them coming. Since those of you driving SUVs and talking while you are driving aren't paying much attention, can you really blame them? They can't dodge you like those who ride sport bikes can.

            I'm only being half sarcastic here. If there was demand for it, you could make them almost absolutely silent. The technology already exists, but when it was introduced a few years ago, the rider portion of the show boycotted the booth. They felt that being silent would make them invisible and thus even more ignored on the freeways.

                This is indisputably true. That's why, because I don't happen to own a bike, I have a 220dB air horn installed on the roof of my 1986 Escort. I had to have special glass and insulation installed in the car, and I still need earplugs when I drive it (because I leave it blaring constantly whenever the car is running), but there's no danger of running over a kid!

                This "You can hear 'em coming" argument is the most arrogant, self-centered, thoughtless, and logically inconsistent argument I've ever heard. As if it's my responsibility as a pedestrian to dodge motorized vehicles, and not theirs to make sure they conduct themselves in a way that leaves me unharmed and with comfortably non-ringing ears.

              The Harley folks make them loud on purpose so you can hear them coming.

              I've had Harley riders insist that this is the reason why they have to have the "Look at me! I'm an attention whore!" straight pipes while cruising in residential neighborhoods; yet even while watching them come and listening for them, I never hear them from very far away. You can always hear them as they roar by, and as they rumble off, though. I think the whole "hear them coming" excuse is a crock.

              One of these same Harley riders insisted, during the very same conversation when I asked him about the mental rider fatigue all that extra noise must put him through, that he never hears his own pipes while cruising. "Hmm..." I asked him, "How can you hear them coming if you can't even hear them from 3 feet away?" "The wind carries the sound away before it gets to my ears" was the answer.

              They felt that being silent would make them invisible and thus even more ignored on the freeways.

              I've found that quiet bikes are much easier to stay alert on, especially in routine rides such as to work and back, and also as the miles add up on long road trips, and that's a far bigger safety factor in this world of sound-insulated luxury cars and SUVs. Most anyone with their windows up won't hear you anyway, unless you're riding with a half dozen others with straight pipes.

              I don't bitch about straight pipe riders much, but I don't have a positive opinion of them, either.

              They can't dodge you like those who ride sport bikes can.

              They can if they're alert, competent riders.

            I wish I had mod points for you, because this is +5 Insightful (if a little off topic). The mentality that drives unnecessarily and excessively loud motorcycles (HD rumbly types) reminds me of people blaring the car stereo with windows down. The only purpose is to cause others grief. And don't get me started about the kids on my lawn.

            • The only purpose is to cause others grief.

              Incorrect, at least in the case of motorcycles- it's a safety issue. One could make the case however, that there's another way to accomplish this, hooking up a bullhorn to an MP3 player with a touch screen interface and all sorts of interesting messages for your average SUV driving idiot.

          Oh yeah. Anyone with an older Little British Car (Triumph, Rover, MG, Austin Healey, etc) knows all about self-maintenance. Perhaps we know a bit too much. ;). If you have one of those cars, you're either a mechanic yourself (pro or hobby), or have way too much disposable income going to support a British car mechanic.

I've driven it for 7 years now. It's never stranded me. It's fun to drive. It's cheap, but it was made in Britain, not Germany and a decade before your Porsche. What's more, parts are very easy to find and cheap.

Give me electronic fuel injection and computer-controlled coil pack ignition any day over a carburetor/coil/distributor setup.

    I've been interested in these devices for a while now. As a design engineer, I don't see much how these new intelligent fasteners will differ much from today's dumb fasteners. Since they are mechanical fasteners, the joint strength considerations remain the same. All fasteners still have to transfer a force, and the concepts of tension, shear, and clamp load don't change with the addition of an embedded system. I suppose that any joint strength you can achieve with a traditional fastener, you can achieve with an intelligent fastener.

    There will be differences, of course. On the plus side, they promise to provide additional design freedom. Tool access and assembly sequences often dictate the fastener locations as much as joint strength does. Now you can put a joint anywhere you want because of the built-in actuation, which can also eliminate some of the tolerance or orientation issues associated with assembly tools. Cross threading could be a thing of the past.

    They also shouldn't present any packaging difficulties, despite their onboard electronics. These fasteners tap into a product's existing wiring and electronics. Digital commands take up far less space than a physical tool. I think that smart fasteners can attain much smaller sizes than conventional mechanical fasteners--in part because they overcome traditional spacing constraints and in part because smart materials will allow them to be smaller, perhaps even down to the nanotechnology scale. Cool stuff indeed.

    Just when Congress appears ready to force auto makers to stop locking nondealer mechanics out of the car's diagnostic computer, they come up with a way to lock them out of changing parts. If they prove to be resistant to the average screwdriver or wrench, we'll know for sure what's up.

    Microchips embedded in fasteners respond only to encrypted signals, restricting access to service procedures. These procedures would be stored in fastener control software, ensuring installation of authorized replacement parts. A central database would retain information on fastener status and maintenance history. All data would be accessible instantly to document warranty claims.

Carbide or diamond cutting wheels and torches can take care of that little problem? I'm taking it apart, who needs to put it back together again!

    Never under estimate the ability to take something apart that was not designed to be taken apart.
    • I'm sorry Carbide and diamond cutting tools will now be banned under the DCMA.
    • Sure, you can do all of that but will you? The auto maker can price their parts just below what you will charge for all of your effort. Don't forget that they are also going to be using bogus IP laws to make sure there's no competition in the air bag maker's market. So, the customer will be faced with you messing with their car to put in the same part the dealership will without "damage" and in less time, perhaps for less money.

    Thanks, but no thanks.

    Hmmm. There has to be some tool that will remove a fastener without the security code, because what happens when a fastener breaks in such a way that it doesn't accept any code? "I'm sorry, you need a new engine, because the fasteners on your oil pan are broken. They don't answer the commands to unfasten." Not likely! So I guess if you are willing to go to a great deal of trouble you could pry out all the secure fasteners and put in your own.

    Of course that would be a DMCA violation, but at least I can hope that the DMCA will be dead long before these fasteners are actually practical for widespread use.

    The article cites labor costs as the main impetus for creating these self-fastening fasteners, but I think it's much more interesting to consider new applications.

    One thing about nuts and bolts is that in order to use them, you have to place them where you have access and enough clearance to be able to attach a tool. You couldn't use nuts and bolts to fasten two blocks together, for example, unless you have holes extending through at least one of the blocks. With these things, you can bolt two blocks together with no obvious access points, and you can unbolt them at any time.

    The benefits of totally blind fastening aren't completely obvious because we've worked out other solutions to the problem. Basically, we either weld things together, or we use some sort of snap-fit system, or we leave access holes if we might need to reverse the attachment. But I expect there will be some interesting applications for these things in the future.

A disassembled robot (with a human brain) is sent to the station along with a specially selected trainer. The trainer puts the robot together and starts training it. Problems ensue with the robot so it is dismantled. The robot reassembles itself, Big problems.

  • This would be useful for situations where a screw is used for varible tensioning, like tuning on a guitar. Especially in a hostile environment.
  • Kind of interesting, my dad was working on a project at Honeywell (then Allied Signal) to design a very similar bolt with built in torque sensor for space applications about 15 years ago. That bolt eventually found its way onto the ISS (the bolt to be used on the ISS was probably designed and built at least another 6 or 7 years ago) and now, car manufactures are looking to mass produce this technology and put it in in millions of cars. Course its nothing new that this is how it happens with technologies,
  • The raticle talks about networking these.

    By my estimate, there will be approximately 37.904 gazillion of these in use within 10 years. That's about 10 years before IPv6 will be widely deployed, so maybe we should just jump to IPv16 right now.
  • The Hillman Imp had self-untapping screws according to an article I read in some article.

    Apparantly DC10's would jetison cargo all by them selves. Nobody undid any screws, locks or retainers.
    Although on a DC10 I was on, a stewardess noticed that the exit door was open, as we were taking off...

    Some engines have self-adjusting tappets.

    Imagine that you had to argue a case with an intelligent fastner to convince it that it was very important that it let you remove it...

  • All I could think about was the screw in the movie rolling around and beeping when I read this :) Can't wait for this to come into being, and then the inevitable experation period when your car falls apart after 60k miles.
  • Keap it Simple, Stupid. Everyone out there knows that, and being an auto mechanic for ten years now, I'd hate to have to track down a problem to a fastener that intermitently lost its connection, decided to to losen itself, or over torque itself and break, or strip its threads. This will never work for two reasons, first off, I don't see how it can ever be cost effective, these things can't be cheap. Second is weight, the reason automakers have all been crying about how they're going to switch to 48 volt sy

    ... remember that feeling you got when the legs sprouted out of that guy's head in John Carpenter's "The Thing" ?
    That's the feeling I get when I hear about something as stupid as this... I mean, I guess it's the illogical evolution of the entire "tamper-resistant" fastener craze of the modern automotive industry, but as a professional mechanic for almost 20 years, I know from experience that fasteners with funny heads on them do not deter the fools and thieves out there from trying to take things apart - they only serve to provoke them into doing much more damage than they would have done had you simply used a normal bolt.

    It's just bulls#it, plain & simple.

    Now nerds can screw over bullies cars even easier than ever! I can just see it now.

    *Nerd presses a few buttons, cars tires flatten and fall off, engine and components fall into a heap, seats, chairs, and straps fall down off of the interior, car trunk pops open and then flings off.*

    Needless to say, whoever thought up this was is a fuckin moron. Why the HELL would I trade my screwdriver's torque for a couple small magnets?

    That isn't amazingly useful. Think back to your Physics class...Torque? Torque is cheap (when you have a big pole). You couldn't use it for anything significant to the operation of a car since most of the bolts there need to be torqued, usually to something more than 30+ ft/lbs. Big things are sometimes torqued to 500+ft/lbs. Lets work with 30ft/lbs.

    Assuming the head of this thing has a whopping 1" radius from the center of the bolt, that's 360 lbs of force the fastner needs to apply. And the largest volume that this fastener will take up? 3.14 in^3? 6.28?

    These screws will only be useful for detailing unless they can tap power magically from anywhere they want.
