I think the closest you could come to open-sourcing the product would be to implement a copyleft license for your patent. There are a bunch of opinions and philosophies of what copyleft licenses should have or encompass, but they generally revolve around letting anyone use your patent as long as they credit you, publish any changes or improvements made on top of your patent, as well as requiring similar licensing on their designs, all together allowing you to use their improvements in your own design.

I'll answer your second question with another; what separates you from manufacturers in China? Answer that and you've a reason for someone to buy them from you. Personally, I'm willing to spend more on a given product to both support domestic manufacturing or to guarantee better quality and support.

I'm glad that you've been able to use patents to your advantage, but they're anti-competitive. It's well known that patents are primarily used to bully small businesses out of the marketplace.

HN, and other tech hubs, know the extreme usefulness of open source. It's not 1-to-1, but patents of physical products don't gel well with the philosophy of open-source.
