If you're a behaviorist, you would define intelligence as "demonstrates problem-solving behavior". If you're not a behaviorist, then it's perfectly reasonable to presuppose some definition of intent. You could further debate how I would define the coffee table itself (https://plato.stanford.edu/entries/object/ https://plato.stanford.edu/entries/object/), but that's the wrong level of analysis.
