What is the quickest way to learn practical industrial design?

I'd like to design physical products that can be mass produced. I know nothing about this field, except that it's called "industrial design".

For an absolute beginner, what is the quickest way to learn enough to be productive in industrial design? Any websites, articles, or resources are greatly appreciated.

Also, any insight into what the process is would be great too. Like what kind of tools are used, what are the industry standards, what kind of file format factories accept, etc.

Thank you!
