How did the goal of the Philadelphia convention change from the time the convention was called until the convention convened

The Philadelphia Convention, held between May and September 1787, was initially convened to modify the Articles of Confederation, with the aim of adapting them to a reality different from that of the United States at the time of its drafting. Thus, the delegates attending would seek to adopt regulations that would allow greater autonomy for the central government in economic, commercial and defense matters.

Now, this convention finally ended up sanctioning the Constitution of the United States, since the delegates ended up realizing that a new fundamental law was necessary for the nation, and not a modification of the Articles.
