Never Get The Size Wrong

What size are they….AA, C, D? Wicked minds! Me is innocently asking you the size of your Batteries. The ones that you use in your gadgets. So you don’t remember exactly, and what if you buy the wrong size? With the AtoD Rechargeable Battery, you’ll never get the size wrong. Why? Coz the one size fits all slots. How? It’s made from memory form, so it squishes to the required size in a squeeze. 1.5 Volts of Nickel Hydroxide power is what you get; recharge it and use it.

    interesting, but…I think that it’s useless.
    The size of battery is not just for ‘size’

  • Gunnar Tveiten says:

    So, you get a battery that *physically* fits in the gadgets wanting bigger batteries. Unfortunately, the capacity is still the puny tiny little one from the smallest possible battery, minus the space for the foam, so yeah, now your boom-box will work — for about 7 minutes.

  • OH says:

    so interesting! I need it!

  • Carl says:

    so how do you squeese a d shape into an aaa? the foam would push battery covers off.

    does the designer think manufacturers make them different sizes for a laugh?

  • Bernard says:

    hmmmm… if you had half a brain cell, you would know that the tubular form provides strength… look at a cola can or a pringles box.

    this thing would be too flimsy…

    summing it up, think first – render later.

  • Zee says:

    They have different sizes for a reason.

  • Henrique Staino says:

    And, frankly, who the hell makes gadgets that use “D”, or “C” batteries theses days?

    No kidding, I haven’t used one since 1999.

  • M.S.W. says:

    Designer was probably inspired by the Eneloop brand rechargeable batteries where the AA batteries can be inserted into C and D type adapters.

    Link to example:

    http://www.amazon.com/Sanyo-Eneloop-Battery-Charger-Batteries/dp/B001RS701Q/ref=sr_1_27?ie=UTF8&qid=1248712882&sr=8-27

    C & D battery styles mainly used these days for Flashlight/torch.

    • Spuffler says:

      Well, IMO, C and D designs should not be rejected from rechargeability. I’m looking for NiMH C cells because my Digital Camera, when using flash, will eat 2 fresh AA rechargeables after less than 30 flash shots. With C cells, I estimate I could do over 2 1/2 times as many flash shots before swapping cells. Since camera manufacturers theorize that the weight of C cells would cause problems, they focus on AA designs (not that the weight would be a big issue – added weight would dampen hand shake, and adding heft is usually seen as a perceptual improvement). If the AA calls in the camera are too low in capacity, I need something bigger and C is the next standard cell size. The same reason existed for C and D before rechargeablility – the energy capacity for a given use is very proportional to volume.

  • Spuffler says:

    The majority of flashlights use D Cells, Henrique Staino, and my boombox also eats D cells, 8 cells at a time.

    Considering device ampere-hours requirements, the statement that Gunnar Tveiten made is simply pointing the first basic flaw in the design here: AA batteries will not last long in a D cell design. Unless there would be a very very low ROI to put this into production, this invention will teach a quick lesson on the needs for multidisciplinary education.

    Another issue is as Carl pointed out – the ever expanding memory foam would push battery covers off of most devices which use AA cells – those covers are weak.

    Bernard, the weakest portion of commonly used packaging cylinders is where forces are acting perpendicular to the cylinder axis. Those perpendicular forces will easily distort the common commercial goods cylinder – that is why you can crush Pringles cans and soda cans with one hand. No consumer merchant wants the container to resist tons per square inch applied perpendicular to the cylinder axis – that is not cost effective!

    Anyways, fail for electrical mismatch, and fail for not knowing the history of consumer goods for AA cell devices.

  • AlienzExist says:

    I’m just surprised it took 3 people to design this.

  • I'm fascinated by this idea, and would love to see how it works in practice, if the batteries actually deliver the power required of them at all sizes and for a reasonable amount of time. Very intriguing idea, though!

  • kit says:

    Good idea thuth

  • Biiij says:

    Sizes differ because Amps differ. They’re all 1,5V but range from 1250 mAmph (AAA) to 20500 mAmph (D).

    One more of these concepts that look so “kewl” (generate some buzz over the brillant mind that imagined it) but never have and never will come to life.

  • Tim Maly says:

    Unless I am missing something very clever about memoryform, wouldn’t the foam expand slowly inside the slot you’d crammed it in to? It’s hard enough getting A batteries out of their cradles without them puffing up and getting stuck.

  • Lamah says:

    I also have doubts that the flat terminal end will cover enough area for reliable contact in devices designed to take D size batteries.

  • proof76 says:

    The idea might be good – but doesn’t make any sense in reality! As most people already said: they make different sizes for a reason!
    Same thought could be used for weightlifting:
    Take a 2lbs weight and blow it up until it looks like a 20lbs weight or whatever you like(I doubt you’ll win the strong man competition, but hey, give it a try;)
    3people worked on this and none of them thought twice about the concept…

  • Shahid says:

    Question is: Once the battery resized from D to AA then how it will be reset its size upto D?

  • Logan says:

    What also isn’t maked clear to the layman is what ‘concept’ means; it’s not in market production, yet. So it may not even be viable.

    And Spuffler makes a valid point; there is a significant flaw in the design, both structurally and mismatched power consumption.

  • Logan says:

    Also, what does “Form Byond Function” really equate? That the form far exceeds the function? What’s the point in that? Doesn’t that sort of negate the purpose of advancements?

  • Drew says:

    Have fun watching your portable devices draw too much current from a AA cell, and then promptly catch on fire or melt.

  • Logan says:

    This post basically sums up Yanko to me. Form over function. Some pretty renderings and poorly hashed out ideas.

  • themark says:

    What amazes me is that three designers all got together and agreed with each other that this was a good idea. And then actually spent time putting this together. Is rendering the only thing that they teach nowadays? Pure farce.

  • Reminder of dignity says:

    You are bitter people.

    Take the idea and make it better if you’re so set on being insulting.

    I don’t recall any of you presenting anything remotely useful or being successful with all the smack you talk. No, I don’t recall a paycheck or respect for that. If you did, I don’t think you’d be such a petty douche and spend time being rude to others on a web page.

    You’d be out enjoying the earned talent you currently don’t have.

    Do something productive but don’t be shooting down other people for having the guts to even try the planning of an idea.

    • dafffffffff says:

      "You'd be out enjoying the earned talent you currently don't have"

      You see that's kind of the point. Three designers all got together and somehow thought this would work and be a good idea, worthy enough of the ensuing render and hype or whatever but 20+ people, most of whom I doubt are designers or electrical engineers/technicians/whatever have called out the mistakes with this design. THREE PEOPLE got together and designed something that common sense (and a small amount of technical knowledge) shows wouldn't work.

      Do something productive but don't be shooting down other people for calling a design out on its mistakes, its woefully obvious mistakes.

      That aside, its a reasonably smart idea, in principle. Just a shame that reality works a little differently.

    • A1Skeptic says:

      You’ll be buying this then? …a good item to keep on hand in case you need an underpowered ‘C’ or ‘D’ battery, or just prefer your ‘AA’ batteries in a “fat suit”! Hey! How about foam socks so you can wear any size shoes?

      • Jayjay says:

        foam socks are actually a slightly better idea than foam batteries… if the foam was deodorized…

  • Ris says:

    Interesting concept…but i do agree that even if the batteries fit coz of the memory form the power still remains the same…different battery sizes are there for a reason…i hope im correct on this!

  • Jon says:

    different battery-"sizes" not only have different capacities but also varying voltages and discharge properties (for example high performance batteries for flashes). basically, apart from the physical requirements of storing different amounts of energies, there are different form-types of batteries so you dont mix them up accidentially (at least not too bad, meaning if you chose the wrong battery it is probably underpowered for your purpose and will do no damage). the designers obviously didn't make the slightest effort of understanding what they tried to "improve". i can only hope it was a freshman's student assignment…

  • tardigrade says:

    I’m surprised nobody here has seen the inherent dangerousness of this product. You ever pull a freshly-charged battery out of its charger? It’s warm, isn’t it? Now imagine putting a thick foam blanket around the battery, then charge it. It would probably get very hot, possibly hot enough to melt the foam and quite likely start a fire if the internals explode. Not a good “concept” at all.

  • Sieb Dykstra says:

    this is a crap idea. if your using a D sized battery with a capacity of AA, then you will have no power what so ever,

  • How would you squeeze that in to an AAA size, wont that pop out the cover of the gadget?

  • Bob says:

    It's a great and interesting theory in my opinion, but as stated it just wouldn't work. The batteries wouldn't have enough power. LIke I said though, I like the theory of it.
