House Training (3X/day in One Spot)

Definitely do not use a shock collar in this manner. That will almost certainly backfire in so many ways and is entirely unnecessary. You can housetrain a puppy to eventually go to the bathroom three times a day in one spot, in relatively short order. It just requires a little while of working with your puppy based on what a puppy is capable of at different stages of puppyhood and some diligent supervision on your part.
