Demo of Short-Range Wireless Power Transfer

You should still be able to do all three. Consider a block around the height of the device and around half the width. You could have one set of coils going around the small edge, one around the middle width-wise, and one around the middle length-wise.

Unless I'm mistaken, that should give you 3 orthogonal coils.

You are both correct and mistaken.

That does give you 3 orthogonal coils, technically, but the other 2 orthogonal planes will get very little power.

Except that won't work due to the reduced cross section of two of the coils.
