Let's take two English sentences to illustrate this. I invented a new type of apple. I produced a new type of apple. If you invent something, it means that you created or designed something that has probably never been created before. If you invented a new type of apple, you invented a type of apple that no one else has ever created. If you produce something on the other hand, you made/manufactured it from components or raw materials. If you produced an apple, it probably means you are selling a new apple that has been made before.
