I think you're placing too much emphasis on the act of invention itself. Figuring out how to build a microwave oven, i.e. inventing it, is but a small part of the enterprise of putting one in every home. Supply chains, marketing, servicing, cost cutting, etc. are all important and tricky parts of it.
Shenanigans. The same infrastructure serves basically all home delivery, marketing, service, etc. There's not a special new highway or chain store or advertising network for every kitchen gadget.
