The unique attribute of my device would be a motor, the purpose of the motor is in use in many common items today, however what the purpose of the motor ( to revolve) would be applied to.............. (a new task) not in use today creating my new idea.
Similar to selling used tires with a chain on them as "Tire Swings"
Or better yet..........Basically, are the "Child Leashes" infringing on "Dog leashes"
What do you think?
does this help?
