Safety Plug by Luofang Jun • Ever been shocked plugging something in? I definitely have. Tip: feeling for the prongs to steer a plug into an outlet isn't all that smart. Luofang Jun's plug redesign is, however, featuring a folding, accordion-like sleeve that'll keep your fingers away from the shocky stuff.

Visible Meter by Muhyeon Kim • Outlets are useful, but stupid. Why not design one that wants to help out? Muhyeon Kim's will let you know how much power you're using, and has a colored ring that will shine blue when a device is in standby, or orange when it's in use. With just a glance you can be smarter about how you use your gadgets.

Universal Plug by Seungwoo Kim • There's not much that's actually universal about the Universal Plug, save for how easy it makes pulling it out of the wall. We've all struggled with tough plugs. The Universal Plug is an elegant solution to make such woes a thing of the past.

Switcle by Junil Choi & Daun Yun • The name isn't as clever as the solution here: the "Switcle" is a mash-up of the switch and the receptacle — in this case, an outlet. Instead of having to juggle outlets with a single switch, you can pick and choose what you turn off right at the source. There's no reason why you couldn't use a regular ol' switch, still, but now the choice is yours.

USB Outlet by Lv Jianhua, He Dawei, Xu Yao & Zhou Hanxiao • Tired of relying on having a computer or an adapter handy to plug in your USB goodies?

Wall Cleat by Karl Zahn • The benefit of this concept is immediately clear and simple: cords are long, and can be a danger on top of being a mess. Wrap 'em up and only use what you need.

Plug Hook by Naoya Edahiro • While it may sound like a good way to poke an eye out, it's also a great way for you to keep your gadgets organized. A hook on a plug would especially be useful on something such as a shaver, cellphone or hairdryer, any one of which you probably have married to an outlet somewhere.

Power Saver Plug by Dongyeon Kim • Even if your television, computer or gadget is turned off, if it's plugged in then it's still drawing power — which costs both you and Mother Nature. The solution? This hand Power Saver Plub disconnects all energy-drawing elements with just one click, but you can still leave it plugged in, because, let's face it, we all leave everything plugged in all the time, used or not.

Energy Lock by Young-suk Kim • Ever put your TV on a timer so it'll turn off after you've started snoozing? The same concept is in effect here. In an upright position (up, center), the Energy Lock is off. When you rotate the plug, you can set it to keep whatever you've got plugged in on for 15, 30 or 45 minutes and so on. Rotate it all the way and your device stays on. Sure, you could just buy a bunch of timers, but this way it's integrated into your life.
