Many childrens toys or other devices that use conventional batteries(ie AA, AAA, C, D) do not have provision for recharging the batteries(TV Remotes, toys etc) There are currently available rechargable batteries(NICAD, LION) but you still have to remove them and put them in the charger(which involves
coins, screwdrivers, fingernails or combinations of all three)
I propose a battery using a standard form factor(AA Etc) but with an induction coil built into the battery with a charging circuit. This would allow you to have a pad (or Pads) that you could place the object with the induction batteries installed onto and it would recharge the batteries no disassembly required.
This could also be integrated into a children's toy shelf or bin such that any toys placed on the shelf will automatically be recharged.
This would be fully compatible with all battery powered objects available today with no modifications.

Better yet, have the toy-box be the charging zone. |

See related idea which doesn't even require a separate charger, just manually shake to charge! |

[Custardguts] Isnt that what i said right here? |

These are really quite different. Have you ever had to charge one of those shakeable recahrge flashlights? Your arm is ready to fall off after about a minute and that gives you like 30 seconds of power(more now with the LEDs but still not a lot) |
|
| |
This is expressly intended to be retrofit able to existing products and can also be used for products that are not amenable to shaking(size, weight, fragility). |
|

"Honey? Why are you shaking the Roomba?" |
|
| |
"I swear officer its my kids dolly I was shaking, the batteries were dead, I would never do that to a Baby!" |
|
| |
[jh] I have 3 of the LED shakeable flashlights, and haven't found the shaking to be arduous. They have the advantage that they can be recharged anytime, anywhere, without resorting to another power source, or even sunlight. |

There is a company [link] about to market an inductive pad, but they seem to have avoided the battery problem by the use of a matching component with the receiving coil, which connects to the charger terminals of the portable device. |
|
| |
Your idea is better due to the standard form factor batteries, but would likely be less efficient due to larger distance between coils. |
|
| |
It will certainly be more efficient than me having to go to the store buy the batteries and change them every 2 hours(Anyones kid have one of those cheap RC cars that use regular batteries?) |
|
| |
I was just about to call this baked (electric toothbrushes and razors already have inductive chargers) but now i see the benefit of yoru approach. good idea, bun for you. |
