Death to the Trapezoid... Next USB Connector Will Be Reversible 408

Posted by Unknown Lamer
from the suffer-no-more dept.
TheRealHocusLocus writes "Extreme bandwidth is nice, intelligent power management is cool... but folks should be spilling into the streets in thankful praise that the next generation miniature USB connector will fit either way. All told — just how many intricate miracle devices have been scrapped in their prime — because a tiny USB port was mangled? For millennia untold chimpanzees and people have been poking termite mounds with round sticks. I for one am glad to see round stick technology make its way into consumer electronics. Death to the trapezoid, bring back the rectangle! So... since we're on roll here... how many other tiny annoyances that lead to big fails are out there?" The new connector will be smaller too.

        No, it's all natural when the cabling is born that way. If you want to see ruined sanctity, ram a current USB plug in the wrong way...

        But I say this is only the first step. Next we must eradicate male - female difference, and have just one plug-socket which will fit, work and feel good no matter how you do the coupling.

      Cue the anti-Lightning connector posts.

      The proprietary nature of Lightning and its excessive control by Apple is bad, but as a functional connector it works pretty well. I can plug my phone in without being able to see anything and thusfar it has been plenty durable, too. (My Proclip car charger/holder uses a lightning/30pin cable in the base, so it gets pretty hard use without any issues).

      I think Apple would have been smart to create a cheap licensing program for it to gain wider adoption, especially for devices that aren't phones or tablets, as well as a more open spec that would have allowed for more innovative use with iPhones for third party components. Now that a USB spec is coming that eliminates the mechanical advantage of Lightning as a plug, the proprietary nature of of Lightning will be more glaring.

      Protip: The USB emblem goes "up". The logo is trademarked, and without it the cables are too frustrating to use. An interesting feat of human engineering indeed.

      Now, let us travel through time far enough into the future that we come to appreciate the greatest connector design possible:

      First, consider the connector with zero lines of symmetry, such as USB, or a polarized pronged plug. There is a 2D plane that the connector travels orthogonal to and which it must breech in order to complete a connection docking sequence. Consider this plane slicing through your connector and receptacle's contacts. Note that there is one receptacle surface for one connector pin passing through the docking plane.

      To the Future! Copy and rotate your receptor 180 degrees in place along the docking plane. Eliminate any conflicting isolation surfaces, and move the pins such that they do not interact with each the other's connection surfaces. Now you have a reversible connector with one line of symmetry in the receptacle. The connector pins can occupy both sets of receptacle contact surfaces, but need only occupy one position to complete the electrical circuits.

      Advance! Now we will perform the same step again, but with a 90 degree increment. Behold! A square connector!

      60 degrees? Hexagonal connectors! Note that just imagining it we can nearly taste the hex filled future!

      Onward, to 45 degrees, and to victory! Octagonal connections even mirror our futurist desire to slice the corners from our square UI windows, and tabs.

      Oh integration, you foul beast. Clearly to see furthest into the future we must have infinite lines of symmetry in our docking plane -- BUT HOW?! With all pins occupying all positions across the USB connector, the left side interacts with the right side. Since connector pins need only exist in one position we need only make the connector pins have zero lines of symmetry -- move all the connector pins to one side. Simultaneously we have a perfectly round receptacle -- Ah, but all intersecting isolation surfaces are removed, this leaves us with only a flat ring of contacts and several pins.

      So, now we will enter a new Dimension! We can stretch the docking plane in the 3rd dimension along the orthogonal connection axis! BEHOLD! We have discovered the most futuristic connector of all time! The Head Phone Jack!

      Now, what's old can finally be new again. Story time is over, now get off my lawn.

They don't say if the existing mini is changing so it seems like this may not effect cell phone style connectors?

I guarantee you that Apple is working on a flat (reversible) replacement for the iPhone 6 or 7 or 8; the only question (other than when) is whether it'll be an open standard that will (over a few years) be embraced by the rest of the industry, proprietary to Apple, or something halfw

I know the 3.5mm is much more universal but the 2.5mm standard is already there, with plenty of adapters for 3.5mm devices, any time someone wants to make a slightly thinner device.

    Connectors that are (un)plugged often should either be symmetrical or clearly indexed. The original (big) USB plug was almost right (in the sense that the plug wouldn't go in the wrong way), except that it was difficult to tell which way the index should be facing. Firewire was a decent implementation of an indexed plug.

    The current micro USB plugs are ridiculous, though. It can takes three tries to plug it in and every time you get it wrong you stress the socket a little. The difference in feel between a correct and incorrect fit is very mushy with some plugs/sockets.

    While we're on the subject, a pure rectangle (a la the USB A plug) is even worse. The USB connector design over the years has been so bad that I wouldn't be too hopeful about what they come up with next.

    • by swb (14022)

      I don't know how, but when plugging a USB A plug it usually takes me more than two tries to get it in. USB B is easier because the plug orientation is more visually apparent.

      Mini-B is less troublesome than Micro-B, which is really hard to work with in low light for old farts like me with presbyopia.

  • Another way to sell us yet another cable to replace one we already have that works just fine.

    It's not easy to pug the connector in upside down, so if someone forces it in in the wrong direction and breaks it, it's not the fault of the connector.

    The WORST connectors are the trapezoidal HDMI connectors. Not only are they orientation specific, but they are often used on heavy cables that pull on the connector causing it to lose contact, and even bend the pins in the socket.

    Add in the fact that the data rate is like a zillion bytes per second and there is an encryption handshake that must go just right at the start and you have a clusterfuck.
