The idea of a lone inventor who makes a discovery or has a sudden clever idea or ___ is maybe a little out of date today. While these types of ___ do still exist, these days companies often have large ___ departments - teams of people who are constantly innovating and perfecting designs. Perhaps they begin with a ___ and then build a ___, or working model. Sometimes during testing there is a ___ when it becomes clear the design has a fault. At this point maybe it is time to start again or go back to the ___. More work is done and there is a ___ - a solution is found. The product can be retested and then, hopefully, manufactured. The company will apply for a ___ for the design so that others cannot copy it and steal the idea.
