That's not really a good example since a cart with two wheels and a two handles anticipates under 35 U.S.C Sec. 102 a cart with a number of wheels and at least one handle. But yea generally you want to describe things with a billion examples, but no statements limiting the scope of your invention. The most devious strategy is that you disclose vague and probably impossible embodiment. Wait 10 years and then write claims that that narrowly target big products that you really couldn't have invented ten years. But the burden is more or less on the accused infringer to provide you didn't describe the new invention in the old patent.
